Writing a dissertation for either a final-year project or a PhD is a large task. Here are a few thoughts to help along the way.

Preparatory reading

Your dissertation should be written in English. If this is not your native language, it is important that you ask someone literate to proof read your dissertation. Your supervisor only has a limited amount of time, so it would be sensible to ask two or three literate friends to read your dissertation before giving it to your supervisor. That way, he or she will be able to concentrate on the technical content without being distracted by the style.

Incidentally, it is a good idea to make sure that one of your readers is not a specialist in your area of research. That way they can check that you have explained the technical concepts in an accessible way.

Chapter 27 of Day's book gives some useful advice on the use (and misuse) of English.

• Tense — You should normally use the present tense when referring to previously published work, and you should use the past tense when referring to your present results. The principal exception to this rule is when describing experiments undertaken by others in the past tense, even if the results that they established are described in the present tense. Results of calculations and statistical analyses should also be in the present tense. So "There are six basic emotions [Ekman, 1972]. I have written a computer program that distinguishes them in photographs of human faces."
• Voice — The active voice is usually more precise and less wordy than the passive voice. So "The system distinguished six emotions" rather than "It was found that the system could distinguish six emotions".
• Person — The general preference nowadays is to write in the first person, although there is still some debate.
• Number — When writing in the first person, use the singular or plural as appropriate. For a dissertation with one author, do not use the "editorial we" in place of "I". The use of "we" by a single author is outrageously pretentious.
• The Future Perfect Web site has some useful hints and tips on English usage.
• Formality — A dissertation is a formal document. Writing in the first person singular is preferred, but remember that you are writing a scientific document not a child's diary. Don't use informal abbreviations like "don't".
• Repetition — Say everything three times: introduce the ideas, explain them, and then give a summary. You can apply this to the whole dissertation with introductory and closing chapters, and to each chapter with introductory and closing sections. However, do not simply copy entire paragraphs. The three variants of the text serve different purposes and should be written differently.
• Sidenotes — Avoid remarks in parentheses and excessive use of footnotes. If something matters, say it in the main text. If it doesn't matter, leave it out.
• References — Citations in brackets are parenthetical remarks. Don't use them as nouns. So "Ekman [1972] identifies six basic emotions" rather than "Six basic emotions are identified in [Ekman, 1972]".
• Simple language — Convoluted sentences with multiple clauses—especially nested using stray punctuation—make it harder for the reader to follow the argument; avoid them. Short sentences are more effective at holding the reader's attention.
• Remember the difference between adjectives and adverbs. Likely is an adjective, probably is an adverb. Purists would also say that due to is an adjectival preposition and owing to is adverbial, but this distinction is now largely lost (although because of probably reads better anyway).
• Try not to use nouns as adjectives. Alas, this is a common problem in Computer Science publications. At the very least, limit the number of nouns that are strung together.
• Try not to split infinitives. It is perfectly good English, but a lot of people don't like it.

Word processing

Learn how to use your word processor effectively. This will probably be MS Word or LaTeX. In either case, make sure that you now how to include numbered figures, tables of contents, indexes, references and a bibliography efficiently. With MS Word, learn how to use styles consistently. With LaTeX, consider a WYSIWYG editor such as LyX.

Think about your house style for pages and for things like fragments of computer programs.

Think of yourself as a member of a jury, listening to a lawyer who is presenting an opening argument. You'll want to know very soon whether the lawyer believes the accused to be guilty or not guilty, and how the lawyer plans to convince you. Readers of academic essays are like jury members: before they have read too far, they want to know what the essay argues as well as how the writer plans to make the argument. After reading your thesis statement, the reader should think, "This essay is going to try to convince me of something. I'm not convinced yet, but I'm interested to see how I might be."

An effective thesis cannot be answered with a simple "yes" or "no." A thesis is not a topic; nor is it a fact; nor is it an opinion. "Reasons for the fall of communism" is a topic. "Communism collapsed in Eastern Europe" is a fact known by educated people. "The fall of communism is the best thing that ever happened in Europe" is an opinion. (Superlatives like "the best" almost always lead to trouble. It's impossible to weigh every "thing" that ever happened in Europe. And what about the fall of Hitler? Couldn't that be "the best thing"?)

A good thesis has two parts. It should tell what you plan to argue, and it should "telegraph" how you plan to argue—that is, what particular support for your claim is going where in your essay.

Steps in Constructing a Thesis

First, analyze your primary sources.  Look for tension, interest, ambiguity, controversy, and/or complication. Does the author contradict himself or herself? Is a point made and later reversed? What are the deeper implications of the author's argument? Figuring out the why to one or more of these questions, or to related questions, will put you on the path to developing a working thesis. (Without the why, you probably have only come up with an observation—that there are, for instance, many different metaphors in such-and-such a poem—which is not a thesis.)

Once you have a working thesis, write it down.  There is nothing as frustrating as hitting on a great idea for a thesis, then forgetting it when you lose concentration. And by writing down your thesis you will be forced to think of it clearly, logically, and concisely. You probably will not be able to write out a final-draft version of your thesis the first time you try, but you'll get yourself on the right track by writing down what you have.

Keep your thesis prominent in your introduction.  A good, standard place for your thesis statement is at the end of an introductory paragraph, especially in shorter (5-15 page) essays. Readers are used to finding theses there, so they automatically pay more attention when they read the last sentence of your introduction. Although this is not required in all academic essays, it is a good rule of thumb.

Anticipate the counterarguments.  Once you have a working thesis, you should think about what might be said against it. This will help you to refine your thesis, and it will also make you think of the arguments that you'll need to refute later on in your essay. (Every argument has a counterargument. If yours doesn't, then it's not an argument—it may be a fact, or an opinion, but it is not an argument.)

This statement is on its way to being a thesis. However, it is too easy to imagine possible counterarguments. For example, a political observer might believe that Dukakis lost because he suffered from a "soft-on-crime" image. If you complicate your thesis by anticipating the counterargument, you'll strengthen your argument, as shown in the sentence below.

Some Caveats and Some Examples

A thesis is never a question.  Readers of academic essays expect to have questions discussed, explored, or even answered. A question ("Why did communism collapse in Eastern Europe?") is not an argument, and without an argument, a thesis is dead in the water.

A thesis is never a list.  "For political, economic, social and cultural reasons, communism collapsed in Eastern Europe" does a good job of "telegraphing" the reader what to expect in the essay—a section about political reasons, a section about economic reasons, a section about social reasons, and a section about cultural reasons. However, political, economic, social and cultural reasons are pretty much the only possible reasons why communism could collapse. This sentence lacks tension and doesn't advance an argument. Everyone knows that politics, economics, and culture are important.

A thesis should never be vague, combative or confrontational.  An ineffective thesis would be, "Communism collapsed in Eastern Europe because communism is evil." This is hard to argue (evil from whose perspective? what does evil mean?) and it is likely to mark you as moralistic and judgmental rather than rational and thorough. It also may spark a defensive reaction from readers sympathetic to communism. If readers strongly disagree with you right off the bat, they may stop reading.

An effective thesis has a definable, arguable claim.  "While cultural forces contributed to the collapse of communism in Eastern Europe, the disintegration of economies played the key role in driving its decline" is an effective thesis sentence that "telegraphs," so that the reader expects the essay to have a section about cultural forces and another about the disintegration of economies. This thesis makes a definite, arguable claim: that the disintegration of economies played a more important role than cultural forces in defeating communism in Eastern Europe. The reader would react to this statement by thinking, "Perhaps what the author says is true, but I am not convinced. I want to read further to see how the author argues this claim."

A thesis should be as clear and specific as possible.  Avoid overused, general terms and abstractions. For example, "Communism collapsed in Eastern Europe because of the ruling elite's inability to address the economic concerns of the people" is more powerful than "Communism collapsed due to societal discontent."

How To Write A Dissertation Introduction

A Simple Explainer With Examples + Free Template

By: Derek Jansen (MBA) | Reviewed By Dr Eunice Rautenbach (D. Tech) | March 2020

If you’re reading this, you’re probably at the daunting early phases of writing up the introduction chapter of your dissertation or thesis. It can be intimidating, I know. 

In this post, we’ll look at the 7 essential ingredients of a strong dissertation or thesis introduction chapter, as well as the essential things you need to keep in mind as you craft each section. We’ll also share some useful tips to help you optimize your approach.

Overview: Writing An Introduction Chapter

• The purpose and function of the intro chapter
• Craft an enticing and engaging opening section
• Provide a background and context to the study
• Clearly define the research problem
• State your research aims, objectives and questions
• Explain the significance of your study
• Identify the limitations of your research
• Outline the structure of your dissertation or thesis

A quick sidenote:

You’ll notice that I’ve used the words dissertation and thesis interchangeably. While these terms reflect different levels of research – for example, Masters vs PhD-level research – the introduction chapter generally contains the same 7 essential ingredients regardless of level. So, in this post, dissertation introduction equals thesis introduction.

Start with why.

To craft a high-quality dissertation or thesis introduction chapter, you need to understand exactly what this chapter needs to achieve. In other words, what’s its purpose ? As the name suggests, the introduction chapter needs to introduce the reader to your research so that they understand what you’re trying to figure out, or what problem you’re trying to solve. More specifically, you need to answer four important questions in your introduction chapter.

These questions are:

• What will you be researching? (in other words, your research topic)
• Why is that worthwhile? (in other words, your justification)
• What will the scope of your research be? (in other words, what will you cover and what won’t you cover)
• What will the limitations of your research be? (in other words, what will the potential shortcomings of your research be?)

Simply put, your dissertation’s introduction chapter needs to provide an overview of your planned research , as well as a clear rationale for it. In other words, this chapter has to explain the “what” and the “why” of your research – what’s it all about and why’s that important.

Simple enough, right?

Well, the trick is finding the appropriate depth of information. As the researcher, you’ll be extremely close to your topic and this makes it easy to get caught up in the minor details. While these intricate details might be interesting, you need to write your introduction chapter on more of a “need-to-know” type basis, or it will end up way too lengthy and dense. You need to balance painting a clear picture with keeping things concise. Don’t worry though – you’ll be able to explore all the intricate details in later chapters.

Now that you understand what you need to achieve from your introduction chapter, we can get into the details. While the exact requirements for this chapter can vary from university to university, there are seven core components that most universities will require. We call these the seven essential ingredients . 

The 7 Essential Ingredients

• The opening section – where you’ll introduce the reader to your research in high-level terms
• The background to the study – where you’ll explain the context of your project
• The research problem – where you’ll explain the “gap” that exists in the current research
• The research aims , objectives and questions – where you’ll clearly state what your research will aim to achieve
• The significance (or justification) – where you’ll explain why your research is worth doing and the value it will provide to the world
• The limitations – where you’ll acknowledge the potential limitations of your project and approach
• The structure – where you’ll briefly outline the structure of your dissertation or thesis to help orient the reader

By incorporating these seven essential ingredients into your introduction chapter, you’ll comprehensively cover both the “ what ” and the “ why ” I mentioned earlier – in other words, you’ll achieve the purpose of the chapter.

Side note – you can also use these 7 ingredients in this order as the structure for your chapter to ensure a smooth, logical flow. This isn’t essential, but, generally speaking, it helps create an engaging narrative that’s easy for your reader to understand. If you’d like, you can also download our free introduction chapter template here.

Alright – let’s look at each of the ingredients now.

#1 – The Opening Section

The very first essential ingredient for your dissertation introduction is, well, an introduction or opening section. Just like every other chapter, your introduction chapter needs to start by providing a brief overview of what you’ll be covering in the chapter.

This section needs to engage the reader with clear, concise language that can be easily understood and digested. If the reader (your marker!) has to struggle through it, they’ll lose interest, which will make it harder for you to earn marks. Just because you’re writing an academic paper doesn’t mean you can ignore the basic principles of engaging writing used by marketers, bloggers, and journalists. At the end of the day, you’re all trying to sell an idea – yours is just a research idea.

So, what goes into this opening section?

Well, while there’s no set formula, it’s a good idea to include the following four foundational sentences in your opening section:

1 – A sentence or two introducing the overall field of your research.

For example:

“Organisational skills development involves identifying current or potential skills gaps within a business and developing programs to resolve these gaps. Management research, including X, Y and Z, has clearly established that organisational skills development is an essential contributor to business growth.”

2 – A sentence introducing your specific research problem.

“However, there are conflicting views and an overall lack of research regarding how best to manage skills development initiatives in highly dynamic environments where subject knowledge is rapidly and continuously evolving – for example, in the website development industry.”

3 – A sentence stating your research aims and objectives.

“This research aims to identify and evaluate skills development approaches and strategies for highly dynamic industries in which subject knowledge is continuously evolving.”.

4 – A sentence outlining the layout of the chapter.

“This chapter will provide an introduction to the study by first discussing the background and context, followed by the research problem, the research aims, objectives and questions, the significance and finally, the limitations.”

As I mentioned, this opening section of your introduction chapter shouldn’t be lengthy . Typically, these four sentences should fit neatly into one or two paragraphs, max. What you’re aiming for here is a clear, concise introduction to your research – not a detailed account.

PS – If some of this terminology sounds unfamiliar, don’t stress – I’ll explain each of the concepts later in this post.

#2 – Background to the study

Now that you’ve provided a high-level overview of your dissertation or thesis, it’s time to go a little deeper and lay a foundation for your research topic. This foundation is what the second ingredient is all about – the background to your study.

So, what is the background section all about?

Well, this section of your introduction chapter should provide a broad overview of the topic area that you’ll be researching, as well as the current contextual factors . This could include, for example, a brief history of the topic, recent developments in the area, key pieces of research in the area and so on. In other words, in this section, you need to provide the relevant background information to give the reader a decent foundational understanding of your research area.

Let’s look at an example to make this a little more concrete.

If we stick with the skills development topic I mentioned earlier, the background to the study section would start by providing an overview of the skills development area and outline the key existing research. Then, it would go on to discuss how the modern-day context has created a new challenge for traditional skills development strategies and approaches. Specifically, that in many industries, technical knowledge is constantly and rapidly evolving, and traditional education providers struggle to keep up with the pace of new technologies.

Importantly, you need to write this section with the assumption that the reader is not an expert in your topic area. So, if there are industry-specific jargon and complex terminology, you should briefly explain that here , so that the reader can understand the rest of your document.

Don’t make assumptions about the reader’s knowledge – in most cases, your markers will not be able to ask you questions if they don’t understand something. So, always err on the safe side and explain anything that’s not common knowledge.

#3 – The research problem

Now that you’ve given your reader an overview of your research area, it’s time to get specific about the research problem that you’ll address in your dissertation or thesis. While the background section would have alluded to a potential research problem (or even multiple research problems), the purpose of this section is to narrow the focus and highlight the specific research problem you’ll focus on.

But, what exactly is a research problem, you ask?

Well, a research problem can be any issue or question for which there isn’t already a well-established and agreed-upon answer in the existing research. In other words, a research problem exists when there’s a need to answer a question (or set of questions), but there’s a gap in the existing literature , or the existing research is conflicting and/or inconsistent.

So, to present your research problem, you need to make it clear what exactly is missing in the current literature and why this is a problem . It’s usually a good idea to structure this discussion into three sections – specifically:

• What’s already well-established in the literature (in other words, the current state of research)
• What’s missing in the literature (in other words, the literature gap)
• Why this is a problem (in other words, why it’s important to fill this gap)

Let’s look at an example of this structure using the skills development topic.

Organisational skills development is critically important for employee satisfaction and company performance (reference). Numerous studies have investigated strategies and approaches to manage skills development programs within organisations (reference).

(this paragraph explains what’s already well-established in the literature)

However, these studies have traditionally focused on relatively slow-paced industries where key skills and knowledge do not change particularly often. This body of theory presents a problem for industries that face a rapidly changing skills landscape – for example, the website development industry – where new platforms, languages and best practices emerge on an extremely frequent basis.

(this paragraph explains what’s missing from the literature)

As a result, the existing research is inadequate for industries in which essential knowledge and skills are constantly and rapidly evolving, as it assumes a slow pace of knowledge development. Industries in such environments, therefore, find themselves ill-equipped in terms of skills development strategies and approaches.

(this paragraph explains why the research gap is problematic)

As you can see in this example, in a few lines, we’ve explained (1) the current state of research, (2) the literature gap and (3) why that gap is problematic. By doing this, the research problem is made crystal clear, which lays the foundation for the next ingredient.

#4 – The research aims, objectives and questions

Now that you’ve clearly identified your research problem, it’s time to identify your research aims and objectives , as well as your research questions . In other words, it’s time to explain what you’re going to do about the research problem.

So, what do you need to do here?

Well, the starting point is to clearly state your research aim (or aims) . The research aim is the main goal or the overarching purpose of your dissertation or thesis. In other words, it’s a high-level statement of what you’re aiming to achieve.

Let’s look at an example, sticking with the skills development topic:

“Given the lack of research regarding organisational skills development in fast-moving industries, this study will aim to identify and evaluate the skills development approaches utilised by web development companies in the UK”.

As you can see in this example, the research aim is clearly outlined, as well as the specific context in which the research will be undertaken (in other words, web development companies in the UK).

Next up is the research objective (or objectives) . While the research aims cover the high-level “what”, the research objectives are a bit more practically oriented, looking at specific things you’ll be doing to achieve those research aims.

Let’s take a look at an example of some research objectives (ROs) to fit the research aim.

• RO1 – To identify common skills development strategies and approaches utilised by web development companies in the UK.
• RO2 – To evaluate the effectiveness of these strategies and approaches.
• RO3 – To compare and contrast these strategies and approaches in terms of their strengths and weaknesses.

As you can see from this example, these objectives describe the actions you’ll take and the specific things you’ll investigate in order to achieve your research aims. They break down the research aims into more specific, actionable objectives.

The final step is to state your research questions . Your research questions bring the aims and objectives another level “down to earth”. These are the specific questions that your dissertation or theses will seek to answer. They’re not fluffy, ambiguous or conceptual – they’re very specific and you’ll need to directly answer them in your conclusions chapter .

The research questions typically relate directly to the research objectives and sometimes can look a bit obvious, but they are still extremely important. Let’s take a look at an example of the research questions (RQs) that would flow from the research objectives I mentioned earlier.

• RQ1 – What skills development strategies and approaches are currently being used by web development companies in the UK?
• RQ2 – How effective are each of these strategies and approaches?
• RQ3 – What are the strengths and weaknesses of each of these strategies and approaches?

As you can see, the research questions mimic the research objectives , but they are presented in question format. These questions will act as the driving force throughout your dissertation or thesis – from the literature review to the methodology and onward – so they’re really important.

A final note about this section – it’s really important to be clear about the scope of your study (more technically, the delimitations ). In other words, what you WILL cover and what you WON’T cover. If your research aims, objectives and questions are too broad, you’ll risk losing focus or investigating a problem that is too big to solve within a single dissertation.

Simply put, you need to establish clear boundaries in your research. You can do this, for example, by limiting it to a specific industry, country or time period. That way, you’ll ringfence your research, which will allow you to investigate your topic deeply and thoroughly – which is what earns marks!

#5 – Significance

Now that you’ve made it clear what you’ll be researching, it’s time to make a strong argument regarding your study’s importance and significance . In other words, now that you’ve covered the what, it’s time to cover the why – enter essential ingredient number 5 – significance.

Of course, by this stage, you’ve already briefly alluded to the importance of your study in your background and research problem sections, but you haven’t explicitly stated how your research findings will benefit the world . So, now’s your chance to clearly state how your study will benefit either industry , academia , or – ideally – both . In other words, you need to explain how your research will make a difference and what implications it will have .

Let’s take a look at an example.

“This study will contribute to the body of knowledge on skills development by incorporating skills development strategies and approaches for industries in which knowledge and skills are rapidly and constantly changing. This will help address the current shortage of research in this area and provide real-world value to organisations operating in such dynamic environments.”

As you can see in this example, the paragraph clearly explains how the research will help fill a gap in the literature and also provide practical real-world value to organisations.

This section doesn’t need to be particularly lengthy, but it does need to be convincing . You need to “sell” the value of your research here so that the reader understands why it’s worth committing an entire dissertation or thesis to it. This section needs to be the salesman of your research. So, spend some time thinking about the ways in which your research will make a unique contribution to the world and how the knowledge you create could benefit both academia and industry – and then “sell it” in this section.

#6 – The limitations

Now that you’ve “sold” your research to the reader and hopefully got them excited about what’s coming up in the rest of your dissertation, it’s time to briefly discuss the potential limitations of your research.

But you’re probably thinking, hold up – what limitations? My research is well thought out and carefully designed – why would there be limitations?

Well, no piece of research is perfect . This is especially true for a dissertation or thesis – which typically has a very low or zero budget, tight time constraints and limited researcher experience. Generally, your dissertation will be the first or second formal research project you’ve ever undertaken, so it’s unlikely to win any research awards…

Simply put, your research will invariably have limitations. Don’t stress yourself out though – this is completely acceptable (and expected). Even “professional” research has limitations – as I said, no piece of research is perfect. The key is to recognise the limitations upfront and be completely transparent about them, so that future researchers are aware of them and can improve the study’s design to minimise the limitations and strengthen the findings.

Generally, you’ll want to consider at least the following four common limitations. These are:

• Your scope – for example, perhaps your focus is very narrow and doesn’t consider how certain variables interact with each other.
• Your research methodology – for example, a qualitative methodology could be criticised for being overly subjective, or a quantitative methodology could be criticised for oversimplifying the situation (learn more about methodologies here ).
• Your resources – for example, a lack of time, money, equipment and your own research experience.
• The generalisability of your findings – for example, the findings from the study of a specific industry or country can’t necessarily be generalised to other industries or countries.

Don’t be shy here. There’s no use trying to hide the limitations or weaknesses of your research. In fact, the more critical you can be of your study, the better. The markers want to see that you are aware of the limitations as this demonstrates your understanding of research design – so be brutal.

#7 – The structural outline

Now that you’ve clearly communicated what your research is going to be about, why it’s important and what the limitations of your research will be, the final ingredient is the structural outline.The purpose of this section is simply to provide your reader with a roadmap of what to expect in terms of the structure of your dissertation or thesis.

In this section, you’ll need to provide a brief summary of each chapter’s purpose and contents (including the introduction chapter). A sentence or two explaining what you’ll do in each chapter is generally enough to orient the reader. You don’t want to get too detailed here – it’s purely an outline, not a summary of your research.

Let’s look at an example:

In Chapter One, the context of the study has been introduced. The research objectives and questions have been identified, and the value of such research argued. The limitations of the study have also been discussed.

In Chapter Two, the existing literature will be reviewed and a foundation of theory will be laid out to identify key skills development approaches and strategies within the context of fast-moving industries, especially technology-intensive industries.

In Chapter Three, the methodological choices will be explored. Specifically, the adoption of a qualitative, inductive research approach will be justified, and the broader research design will be discussed, including the limitations thereof.

So, as you can see from the example, this section is simply an outline of the chapter structure, allocating a short paragraph to each chapter. Done correctly, the outline will help your reader understand what to expect and reassure them that you’ll address the multiple facets of the study.

By the way – if you’re unsure of how to structure your dissertation or thesis, be sure to check out our video post which explains dissertation structure .

Keep calm and carry on.

Hopefully you feel a bit more prepared for this challenge of crafting your dissertation or thesis introduction chapter now. Take a deep breath and remember that Rome wasn’t built in a day – conquer one ingredient at a time and you’ll be firmly on the path to success.

Let’s quickly recap – the 7 ingredients are:

• The opening section – where you give a brief, high-level overview of what your research will be about.
• The study background – where you introduce the reader to key theory, concepts and terminology, as well as the context of your study.
• The research problem – where you explain what the problem with the current research is. In other words, the research gap.
• The research aims , objectives and questions – where you clearly state what your dissertation will investigate.
• The significance – where you explain what value your research will provide to the world.
• The limitations – where you explain what the potential shortcomings and limitations of your research may be.
• The structural outline – where you provide a high-level overview of the structure of your document

If you bake these ingredients into your dissertation introduction chapter, you’ll be well on your way to building an engaging introduction chapter that lays a rock-solid foundation for the rest of your document.

Remember, while we’ve covered the essential ingredients here, there may be some additional components that your university requires, so be sure to double-check your project brief!

The instruction given are perfect and clear. I was supposed to take the course , unfortunately in Nepal the service is not avaialble.However, I am much more hopeful that you will provide require documents whatever you have produced so far.

Thank you very much

Thanks so much ❤️😘 I feel am ready to start writing my research methodology

This is genuinely the most effective advice I have ever been given regarding academia. Thank you so much!

This is one of the best write up I have seen in my road to PhD thesis. regards, this write up update my knowledge of research

I was looking for some good blogs related to Education hopefully your article will help. Thanks for sharing.

This is an awesome masterpiece. It is one of the most comprehensive guides to writing a Dissertation/Thesis I have seen and read.

You just saved me from going astray in writing a Dissertation for my undergraduate studies. I could not be more grateful for such a relevant guide like this. Thank you so much.

Thank you so much Derek, this has been extremely helpful!!

I do have one question though, in the limitations part do you refer to the scope as the focus of the research on a specific industry/country/chronological period? I assume that in order to talk about whether or not the research could be generalized, the above would need to be already presented and described in the introduction.

Thank you again!

Phew! You have genuinely rescued me. I was stuck how to go about my thesis. Now l have started. Thank you.

This is the very best guide in anything that has to do with thesis or dissertation writing. The numerous blends of examples and detailed insights make it worth a read and in fact, a treasure that is worthy to be bookmarked.

Thanks a lot for this masterpiece!

Powerful insight. I can now take a step

Thank you very much for these valuable introductions to thesis chapters. I saw all your videos about writing the introduction, discussion, and conclusion chapter. Then, I am wondering if we need to explain our research limitations in all three chapters, introduction, discussion, and conclusion? Isn’t it a bit redundant? If not, could you please explain how can we write in different ways? Thank you.

Excellent!!! Thank you…

Thanks for this informative content. I have a question. The research gap is mentioned in both the introduction and literature section. I would like to know how can I demonstrate the research gap in both sections without repeating the contents?

I’m incredibly grateful for this invaluable content. I’ve been dreading compiling my postgrad thesis but breaking each chapter down into sections has made it so much easier for me to engage with the material without feeling overwhelmed. After relying on your guidance, I’m really happy with how I’ve laid out my introduction.

Thank you for the informative content you provided

Hi Derrick and Team, thank you so much for the comprehensive guide on how to write a dissertation or a thesis introduction section. For some of us first-timers, it is a daunting task. However, the instruction with relevant examples makes it clear and easy to follow through. Much appreciated.

It was so helpful. God Bless you. Thanks very much

I thank you Grad coach for your priceless help. I have two questions I have learned from your video the limitations of the research presented in chapter one. but in another video also presented in chapter five. which chapter limitation should be included? If possible, I need your answer since I am doing my thesis. how can I explain If I am asked what is my motivation for this research?

Thank you guys for the great work you are doing. Honestly, you have made the research to be interesting and simplified. Even a novice will easily grasp the ideas you put forward, Thank you once again.

Excellent piece!

I feel like just settling for a good topic is usually the hardest part.

Thank you so much. My confidence has been completely destroyed during my first year of PhD and you have helped me pull myself together again

Happy to help 🙂

I am so glad I ran into your resources and did not waste time doing the wrong this. Research is now making so much sense now.

Gratitude to Derrick and the team I was looking for a solid article that would aid me in drafting the thesis’ introduction. I felt quite happy when I came across the piece you wrote because it was so well-written and insightful. I wish you success in the future.

thank you so much. God Bless you

Thank you so much Grad Coach for these helpful insights. Now I can get started, with a great deal of confidence.

It’s ‘alluded to’ not ‘eluded to’.

Dissertation Methodology

In any research, the methodology chapter is one of the key components of your dissertation. It provides a detailed description of the methods you used to conduct your research and helps readers understand how you obtained your data and how you plan to analyze it. This section is crucial for replicating the study and validating its results.

Here are the basic elements that are typically included in a dissertation methodology:

• Introduction : This section should explain the importance and goals of your research .
• Research Design : Outline your research approach and why it’s appropriate for your study. You might be conducting an experimental research, a qualitative research, a quantitative research, or a mixed-methods research.
• Data Collection : This section should detail the methods you used to collect your data. Did you use surveys, interviews, observations, etc.? Why did you choose these methods? You should also include who your participants were, how you recruited them, and any ethical considerations.
• Data Analysis : Explain how you intend to analyze the data you collected. This could include statistical analysis, thematic analysis, content analysis, etc., depending on the nature of your study.
• Reliability and Validity : Discuss how you’ve ensured the reliability and validity of your study. For instance, you could discuss measures taken to reduce bias, how you ensured that your measures accurately capture what they were intended to, or how you will handle any limitations in your study.
• Ethical Considerations : This is where you state how you have considered ethical issues related to your research, how you have protected the participants’ rights, and how you have complied with the relevant ethical guidelines.
• Limitations : Acknowledge any limitations of your methodology, including any biases and constraints that might have affected your study.
• Summary : Recap the key points of your methodology chapter, highlighting the overall approach and rationalization of your research.

Types of Dissertation Methodology

The type of methodology you choose for your dissertation will depend on the nature of your research question and the field you’re working in. Here are some of the most common types of methodologies used in dissertations:

Experimental Research

This involves creating an experiment that will test your hypothesis. You’ll need to design an experiment, manipulate variables, collect data, and analyze that data to draw conclusions. This is commonly used in fields like psychology, biology, and physics.

Survey Research

This type of research involves gathering data from a large number of participants using tools like questionnaires or surveys. It can be used to collect a large amount of data and is often used in fields like sociology, marketing, and public health.

Qualitative Research

This type of research is used to explore complex phenomena that can’t be easily quantified. Methods include interviews, focus groups, and observations. This methodology is common in fields like anthropology, sociology, and education.

Quantitative Research

Quantitative research uses numerical data to answer research questions. This can include statistical, mathematical, or computational techniques. It’s common in fields like economics, psychology, and health sciences.

Case Study Research

This type of research involves in-depth investigation of a particular case, such as an individual, group, or event. This methodology is often used in psychology, social sciences, and business.

Mixed Methods Research

This combines qualitative and quantitative research methods in a single study. It’s used to answer more complex research questions and is becoming more popular in fields like social sciences, health sciences, and education.

Action Research

This type of research involves taking action and then reflecting upon the results. This cycle of action-reflection-action continues throughout the study. It’s often used in fields like education and organizational development.

Longitudinal Research

This type of research involves studying the same group of individuals over an extended period of time. This could involve surveys, observations, or experiments. It’s common in fields like psychology, sociology, and medicine.

Ethnographic Research

This type of research involves the in-depth study of people and cultures. Researchers immerse themselves in the culture they’re studying to collect data. This is often used in fields like anthropology and social sciences.

Structure of Dissertation Methodology

The structure of a dissertation methodology can vary depending on your field of study, the nature of your research, and the guidelines of your institution. However, a standard structure typically includes the following elements:

• Introduction : Briefly introduce your overall approach to the research. Explain what you plan to explore and why it’s important.
• Research Design/Approach : Describe your overall research design. This can be qualitative, quantitative, or mixed methods. Explain the rationale behind your chosen design and why it is suitable for your research questions or hypotheses.
• Data Collection Methods : Detail the methods you used to collect your data. You should include what type of data you collected, how you collected it, and why you chose this method. If relevant, you can also include information about your sample population, such as how many people participated, how they were chosen, and any relevant demographic information.
• Data Analysis Methods : Explain how you plan to analyze your collected data. This will depend on the nature of your data. For example, if you collected quantitative data, you might discuss statistical analysis techniques. If you collected qualitative data, you might discuss coding strategies, thematic analysis, or narrative analysis.
• Reliability and Validity : Discuss how you’ve ensured the reliability and validity of your research. This might include steps you took to reduce bias or increase the accuracy of your measurements.
• Ethical Considerations : If relevant, discuss any ethical issues associated with your research. This might include how you obtained informed consent from participants, how you ensured participants’ privacy and confidentiality, or any potential conflicts of interest.
• Limitations : Acknowledge any limitations in your research methodology. This could include potential sources of bias, difficulties with data collection, or limitations in your analysis methods.
• Summary/Conclusion : Briefly summarize the key points of your methodology, emphasizing how it helps answer your research questions or hypotheses.

How to Write Dissertation Methodology

Writing a dissertation methodology requires you to be clear and precise about the way you’ve carried out your research. It’s an opportunity to convince your readers of the appropriateness and reliability of your approach to your research question. Here is a basic guideline on how to write your methodology section:

1. Introduction

Start your methodology section by restating your research question(s) or objective(s). This ensures your methodology directly ties into the aim of your research.

2. Approach

Identify your overall approach: qualitative, quantitative, or mixed methods. Explain why you have chosen this approach.

• Qualitative methods are typically used for exploratory research and involve collecting non-numerical data. This might involve interviews, observations, or analysis of texts.
• Quantitative methods are used for research that relies on numerical data. This might involve surveys, experiments, or statistical analysis.
• Mixed methods use a combination of both qualitative and quantitative research methods.

3. Research Design

Describe the overall design of your research. This could involve explaining the type of study (e.g., case study, ethnography, experimental research, etc.), how you’ve defined and measured your variables, and any control measures you’ve implemented.

4. Data Collection

Explain in detail how you collected your data.

• If you’ve used qualitative methods, you might detail how you selected participants for interviews or focus groups, how you conducted observations, or how you analyzed existing texts.
• If you’ve used quantitative methods, you might detail how you designed your survey or experiment, how you collected responses, and how you ensured your data is reliable and valid.

5. Data Analysis

Describe how you analyzed your data.

• If you’re doing qualitative research, this might involve thematic analysis, discourse analysis, or grounded theory.
• If you’re doing quantitative research, you might be conducting statistical tests, regression analysis, or factor analysis.

Discuss any ethical issues related to your research. This might involve explaining how you obtained informed consent, how you’re protecting participants’ privacy, or how you’re managing any potential harms to participants.

7. Reliability and Validity

Discuss the steps you’ve taken to ensure the reliability and validity of your data.

• Reliability refers to the consistency of your measurements, and you might discuss how you’ve piloted your instruments or used standardized measures.
• Validity refers to the accuracy of your measurements, and you might discuss how you’ve ensured your measures reflect the concepts they’re supposed to measure.

8. Limitations

Every study has its limitations. Discuss the potential weaknesses of your chosen methods and explain any obstacles you faced in your research.

9. Conclusion

Summarize the key points of your methodology, emphasizing how it helps to address your research question or objective.

Example of Dissertation Methodology

An Example of Dissertation Methodology is as follows:

Chapter 3: Methodology

• Introduction

This chapter details the methodology adopted in this research. The study aimed to explore the relationship between stress and productivity in the workplace. A mixed-methods research design was used to collect and analyze data.

Research Design

This study adopted a mixed-methods approach, combining quantitative surveys with qualitative interviews to provide a comprehensive understanding of the research problem. The rationale for this approach is that while quantitative data can provide a broad overview of the relationships between variables, qualitative data can provide deeper insights into the nuances of these relationships.

Data Collection Methods

Quantitative Data Collection : An online self-report questionnaire was used to collect data from participants. The questionnaire consisted of two standardized scales: the Perceived Stress Scale (PSS) to measure stress levels and the Individual Work Productivity Questionnaire (IWPQ) to measure productivity. The sample consisted of 200 office workers randomly selected from various companies in the city.

Qualitative Data Collection : Semi-structured interviews were conducted with 20 participants chosen from the initial sample. The interview guide included questions about participants’ experiences with stress and how they perceived its impact on their productivity.

Data Analysis Methods

Quantitative Data Analysis : Descriptive and inferential statistics were used to analyze the survey data. Pearson’s correlation was used to examine the relationship between stress and productivity.

Qualitative Data Analysis : Interviews were transcribed and subjected to thematic analysis using NVivo software. This process allowed for identifying and analyzing patterns and themes regarding the impact of stress on productivity.

Reliability and Validity

To ensure reliability and validity, standardized measures with good psychometric properties were used. In qualitative data analysis, triangulation was employed by having two researchers independently analyze the data and then compare findings.

Ethical Considerations

All participants provided informed consent prior to their involvement in the study. They were informed about the purpose of the study, their rights as participants, and the confidentiality of their responses.

Limitations

The main limitation of this study is its reliance on self-report measures, which can be subject to biases such as social desirability bias. Moreover, the sample was drawn from a single city, which may limit the generalizability of the findings.

Where to Write Dissertation Methodology

In a dissertation or thesis, the Methodology section usually follows the Literature Review. This placement allows the Methodology to build upon the theoretical framework and existing research outlined in the Literature Review, and precedes the Results or Findings section. Here’s a basic outline of how most dissertations are structured:

• Acknowledgements
• Literature Review (or it may be interspersed throughout the dissertation)
• Methodology
• Results/Findings
• References/Bibliography

In the Methodology chapter, you will discuss the research design, data collection methods, data analysis methods, and any ethical considerations pertaining to your study. This allows your readers to understand how your research was conducted and how you arrived at your results.

Advantages of Dissertation Methodology

The dissertation methodology section plays an important role in a dissertation for several reasons. Here are some of the advantages of having a well-crafted methodology section in your dissertation:

• Clarifies Your Research Approach : The methodology section explains how you plan to tackle your research question, providing a clear plan for data collection and analysis.
• Enables Replication : A detailed methodology allows other researchers to replicate your study. Replication is an important aspect of scientific research because it provides validation of the study’s results.
• Demonstrates Rigor : A well-written methodology shows that you’ve thought critically about your research methods and have chosen the most appropriate ones for your research question. This adds credibility to your study.
• Enhances Transparency : Detailing your methods allows readers to understand the steps you took in your research. This increases the transparency of your study and allows readers to evaluate potential biases or limitations.
• Helps in Addressing Research Limitations : In your methodology section, you can acknowledge and explain the limitations of your research. This is important as it shows you understand that no research method is perfect and there are always potential weaknesses.
• Facilitates Peer Review : A detailed methodology helps peer reviewers assess the soundness of your research design. This is an important part of the publication process if you aim to publish your dissertation in a peer-reviewed journal.
• Establishes the Validity and Reliability : Your methodology section should also include a discussion of the steps you took to ensure the validity and reliability of your measurements, which is crucial for establishing the overall quality of your research.

What is the methodology?

The methodology of a dissertation is like constructing a house of cards. Having strong and stable foundations for your research relies on your ability to make informed and rational choices about the design of your study. Everything from this point on – your results and discussion –  rests on these decisions, like the bottom layer of a house of cards.

The methodology is where you explicitly state, in relevant detail, how you conduced your study in direct response to your research question(s) and/or hypotheses. You should work through the linear process of devising your study to implementing it, covering the important choices you made and any potential obstacles you faced along the way.

Methods or methodology?

Some disciplines refer to this chapter as the research methods , whilst others call it the methodology . The two are often used interchangeably, but they are slightly different. The methods chapter outlines the techniques used to conduct the research and the specific steps taken throughout the research process. The methodology also outlines how the research was conducted, but is particularly interested in the philosophical underpinning that shapes the research process. As indicated by the suffix, -ology , meaning the study of something, the methodology is like the study of research, as opposed to simply stating how the research was conducted.

This guide focuses on the methodology, as opposed to the methods, although the content and guidance can be tailored to a methods chapter. Every dissertation is different and every methodology has its own nuances, so ensure you adapt the content here to your research and always consult your supervisor for more detailed guidance.

What are my markers looking for?

Your markers are looking   for your understanding of the complex process behind original (see definition) research. They are assessing your ability to...

• Demonstrate   an understanding of the impact that methodological choices can have on the reliability and validity of your findings, meaning you should engage with ‘why’ you did that, as opposed to simply ‘what’ you did.
• Make   informed methodological choices that clearly relate to your research question(s).

But what does it mean to engage in 'original' research? Originality doesn’t strictly mean you should be inventing something entirely new. Originality comes in many forms, from updating the application of a theory, to adapting a previous experiment for new purposes – it’s about making a worthwhile contribution.

Structuring your methodology

The methodology chapter should outline the research process undertaken, from selecting the method to articulating the tool or approach adopted to analyse your results. Because you are outlining this process, it's important that you structure your methodology in a linear way, showing how certain decisions have impacted on subsequent choices.

Scroll to continue reading, or click a link below to jump immediately to that section:

The 'research onion'

To ensure you write your methodology in a linear way, it can be useful to think of the methodology in terms of layers, as shown in the figure below.

Figure: 'Research onion' from Saunders et al. (2007).

You don't need to precisely follow these exact layers as some won't be relevant to your research. However, the layered 'out to in' structure developed by Saunders et al. (2007) is appropriate for any methodology chapter because it guides your reader through the process in a linear fashion, demonstrating how certain decisions impacted on others. For example, you need to state whether your research is qualitative, quantitative or mixed before articulating your precise research method. Likewise, you need to explain how you collected your data before you inform the reader of how you subsequently analysed that data.

Using this linear approach from 'outer' layer to 'inner' layer, the next sections will take you through the most common layers used to structure a methodology chapter.

Introduction and research outline

Like any chapter, you should open your methodology with an introduction. It's good to start by briefly restating the research problem, or gap, that you're addressing, along with your research question(s) and/or hypotheses. Following this, it's common to provide a very condensed statement that outlines the most important elements of your research design. Here's a short example:

This study adopted qualitative research through a series of semi-structured interviews with seven experienced industry professionals.

Like any other introduction, you can then provide a brief statement outlining what the chapter is about and how it's structured (e.g., an essay map ).

Restating the research problem (or gap) and your research question(s) and/or hypotheses creates a natural transition from your previous review of the literature - which helped you to identify the gap or problem - to how you are now going to address such a problem. Your markers are also going to assess the relevance and suitability of your method and methodological choices against your research question(s), so it's good to 'frame' the entire chapter around the research question(s) by bringing them to the fore.

Research philosophy

A research philosophy is an underlying belief that shapes the way research is conducted. For this reason, as featured in the 'research onion' above, the philosophy should be the outermost layer - the first methodological issue you deal with following the introduction and research outline - because every subsequent choice, from the method employed to the way you analyse data, is directly influenced by your philosophical stance.

You can say something about other philosophies, but it's best to directly relate this to your research and the philosophy you have selected - why the other philosophy isn't appropriate for you to adopt, for instance. Otherwise, explain to your reader the philosophy you have selected (using secondary literature), its underlying principles, and why this philosophy, therefore, is particularly relevant to your research.

The research philosophy is sometimes featured in a methodology chapter, but not always. It depends on the conventions within your school or discipline , so only include this if it's expected.

The reason for outlining the research philosophy is to show your understanding of the role that your chosen philosophy plays in shaping the design and approach of your research study. The philosophy you adopt also indicates your worldview (in the context of this research), which is an important way of highlighting the role you, the researcher, play in shaping new knowledge.

Research method

This is where you state whether you're doing qualitative, quantitative or mixed-methods research before outlining the exact instrument or strategy (see definition) adopted for research (interviews, case study, etc.). It's also important that you explain why you have chosen that particular method and strategy. You can also explain why you're not adopting an alternate form of research, or why you haven't used a particular instrument, but keep this brief and use it to reinforce why you have chosen your method and strategy.

Your research method, more than anything else, is going to directly influence how effectively you answer your research question(s). For that reason, it's crucial that you emphasise the suitability of your chosen method and instrument for the purposes of your research.                       

Data collection

The data collection part of your methodology explain the process of how you accessed and collected your data. Using an interview as a qualitative example, this might include the criteria for selecting participants, how you recruited the participants and how and where you conducted the interviews. There is often some overlap with data collection and research method, so don't worry about this. Just make sure you get the essential information across to your reader.

The details of how you accessed and collected your data are important for replicability purposes - the ability for someone to adopt the same approach and repeat the study. It's also important to include this information for reliability and consistency purposes (see  validity and reliability  on the next tab of this guide for more).

Data analysis

After describing how you collected the data, you need to identify your chosen method of data analysis. Inevitably, this will vary depending on whether your research is qualitative or quantitative (see note below).

Qualitative research tends to be narrative-based where forms of ‘coding’ are employed to categorise and group the data into meaningful themes and patterns (Bui, 2014). Quantitative deals with numerical data meaning some form of statistical approach is taken to measure the results against the research question(s).

Tell your reader which data analysis software (such as SPSS or Atlast.ti) or method you’ve used and why, using relevant literature. Again, you can mention other data analysis tools that you haven’t used, but keep this brief and relate it to your discussion of your chosen approach. This isn’t to be confused with the results and discussion chapters where you actually state and then analyse your results. This is simply a discussion of the approach taken, how you applied this approach to your data and why you opted for this method of data analysis.

Detail of how you analysed your data helps to contextualise your results and discussion chapters. This is also a validity issue (see next tab of guide), as you need to ensure that your chosen method for data analysis helps you to answer your research question(s) and/or respond to your hypotheses. To use an example from Bui (2014: 155), 'if one of the research questions asks whether the participants changed their behaviour before and after the study, then one of the procedures for data analysis needs to be a comparison of the pre- and postdata'.

Validity and reliability

Validity simply refers to whether the research method(s) and instrument(s) applied are directly suited to meet the purposes of your research – whether they help you to answer your research question(s), or allow you to formulate a response to your hypotheses.

Validity can be separated into two forms: internal and external. The difference between the two is defined by what exists inside the study (internal) and what exists outside the study (external).

• Internal validity is the extent to which ‘the results obtained can be attributed to the manipulation of the independent variable' (Salkind, 2011: 147).
• External validity refers to the application of your study’s findings outside the setting of your study. This is known as generalisability , meaning to what extent are the results applicable to a wider context or population.

Reliability

Reliability refers to the consistency with which you designed and implemented your research instrument(s). The idea behind this is to ensure that someone else could replicate your study and, by applying the instrument in the exact same way, would achieve the same results. This is crucial to quantitative and scientific based research, but isn’t strictly the case with qualitative research given the subjective nature of the data.

With qualitative data, it’s important to emphasise that data was collected in a consistent way to avoid any distortions. For example, let’s say you’ve circulated a questionnaire to participants. You would want to ensure that every participant receives the exact same questionnaire with precisely the same questions and wording, unless different questionnaires are required for different members of the sample for the purposes of the research.

Ethical considerations

Any research involving human participants needs to consider ethical factors. In response, you need to show your markers that you have implemented the necessary measures to cover the relevant ethical issues. These are some of the factors that are typically included:

• How did you gain the consent of participants, and how did you formally record this consent?
• What measures did you take to ensure participants had enough understanding of their role to make an informed decision, including the right to withdraw at any stage?
• What measures did you take to maintain the confidentiality of participants during the research and, potentially, for the write-up?
• What measures did you take to store the raw data and protect it from external access and use prior to the write-up?

These are only a few examples of the ethical factors you need to write about in your methodology. Depending on the nature of your research, ethical considerations might form a significant part of your methodology chapter, or may only constitute a few sentences. Either way, it’s imperative that you show your markers that you’ve considered the relevant ethical implications of your research.

Limitations

Don’t make the mistake of ignoring the limitations of your study (see the next tab, 'What to Avoid', for more on this) – it’s a common part of research and should be confronted. Limitations of research can be diverse, but tend to be logistical issues relating to time, scope and access . Whilst accepting that your study has certain limitations, the key is to put a positive spin on it, like the example below:

Despite having a limited sample size compared to other similar studies, the number of participants is enough to provide sufficient data, whilst the in-depth nature of the interviews facilitates detailed responses from participants.

What to avoid

This portion of the guide will cover some common missteps you should try to avoid in writing your methodology.

Ignoring limitations

It might seem instinctive to hide any flaws or limitations with your research to protect yourself from criticism. However, you need to highlight any problems you encountered during the research phase, or any limitations with your approach. Your markers are expecting you to engage with these limitations and highlight the kind of impact they may have had on your research.

Just be careful that you don’t overstress these limitations. Doing so could undermine the reliability and validity of your results, and your credibility as a researcher.

Literature review of methods

Don’t mistake your methodology chapter as a detailed review of methods employed in other studies. This level of detail should, where relevant, be incorporated in the literature review chapter, instead (see our Writing the Literature Review guide ). Any reference to methodological choices made by other researchers should come into your methodology chapter, but only in support of the decisions you made.

Unnecessary detail

It’s important to be thorough in a methodology chapter. However, don’t include unnecessary levels of detail. You should provide enough detail that allows other researchers to replicate or adapt your study, but don’t bore your reader with obvious or extraneous detail.

Any materials or content that you think is worth including, but not essential in the chapter, could be included in an appendix (see definition). These don’t count towards your word count (unless otherwise stated), and they can provide further detail and context for your reader. For instance, it’s quite common to include a copy of a questionnaire in an appendix, or a list of interview questions.

Q: Should the methodology be in the past or present tense?

A: The past tense. The study has already been conducted and the methodological decisions have been implemented, meaning the chapter should be written in the past tense. For example...

Data was collected over the course of four weeks.

I informed participants of their right to withdraw at any time.

The surveys included ten questions about job satisfaction and ten questions about familial life (see Appendix).

Q: Should the methodology include secondary literature?

A: Yes, where relevant. Unlike the literature review, the methodology is driven by what you did rather than what other people have done. However, you should still draw on secondary sources, when necessary, to support your methodological decisions.

Q: Do you still need to write a methodology for secondary research?

A: Yes, although it might not form a chapter, as such. Including some detail on how you approached the research phase is always a crucial part of a dissertation, whether primary or secondary. However, depending on the nature of your research, you may not have to provide the same level of detail as you would with a primary-based study.

For example, if you’re analysing two particular pieces of literature, then you probably need to clarify how you approached the analysis process, how you use the texts (whether you focus on particular passages, for example) and perhaps why these texts are scrutinised, as opposed to others from the relevant literary canon.

In such cases, the methodology may not be a chapter, but might constitute a small part of the introduction. Consult your supervisor for further guidance.

Q: Should the methodology be in the first-person or third?

A: It’s important to be consistent , so you should use whatever you’ve been using throughout your dissertation. Third-person is more commonly accepted, but certain disciplines are happy with the use of first-person. Just remember that the first-person pronoun can be a distracting, but powerful device, so use it sparingly. Consult your supervisor for further guidance.

It’s important to remember that all research is different and, as such, the methodology chapter is likely to be very different from dissertation to dissertation. Whilst this guide has covered the most common and essential layers featured in a methodology, your methodology might be very different in terms of what you focus on, the depth of focus and the wording used.

What’s important to remember, however, is that every methodology chapter needs to be structured in a linear, layered way that guides the reader through the methodological process in sequential order. Through this, your marker can see how certain decisions have impacted on others, showing your understanding of the research process.

Here’s a final checklist for writing your methodology. Remember that not all of these points will be relevant for your methodology, so make sure you cover whatever’s appropriate for your dissertation. The asterisk (*) indicates any content that might not be relevant for your dissertation. You can download a copy of the checklist to save and edit via the Word document, below.

Writing your dissertation - structure and sections

Posted in: dissertations

In this post, we look at the structural elements of a typical dissertation. Your department may wish you to include additional sections but the following covers all core elements you will need to work on when designing and developing your final assignment.

The table below illustrates a classic dissertation layout with approximate lengths for each section.

Hopkins, D. and Reid, T., 2018.  The Academic Skills Handbook: Your Guid e to Success in Writing, Thinking and Communicating at University . Sage.

Your title should be clear, succinct and tell the reader exactly what your dissertation is about. If it is too vague or confusing, then it is likely your dissertation will be too vague and confusing. It is important therefore to spend time on this to ensure you get it right, and be ready to adapt to fit any changes of direction in your research or focus.

In the following examples, across a variety of subjects, you can see how the students have clearly identified the focus of their dissertation, and in some cases target a problem that they will address:

An econometric analysis of the demand for road transport within the united Kingdom from  1965 to 2000

To what extent does payment card fraud affect UK bank profitability and bank stakeholders?  Does this justify fraud prevention?

A meta-analysis of implant materials for intervertebral disc replacement and regeneration.

The role of ethnic institutions in social development; the case of Mombasa, Kenya.

Why haven’t biomass crops been adopted more widely as a source of renewable energy in the United Kingdom?

Mapping the criminal mind: Profiling and its limitation.

The Relative Effectiveness of Interferon Therapy for Chronic Hepatitis C

Under what conditions did the European Union exhibit leadership in international climate change negotiations from 1992-1997, 1997-2005 and 2005-Copenhagen respectively?

The first thing your reader will read (after the title) is your abstract. However, you need to write this last. Your abstract is a summary of the whole project, and will include aims and objectives, methods, results and conclusions. You cannot write this until you have completed your write-up.

Introduction

Your introduction should include the same elements found in most academic essay or report assignments, with the possible inclusion of research questions. The aim of the introduction is to set the scene, contextualise your research, introduce your focus topic and research questions, and tell the reader what you will be covering.  It should move from the general  and work towards the specific. You should include the following:

• Attention-grabbing statement (a controversy, a topical issue, a contentious view, a recent problem etc)
• Background and context
• Introduce the topic, key theories, concepts, terms of reference, practices, (advocates and critic)
• Introduce the problem and focus of your research
• Set out your research question(s) (this could be set out in a separate section)
• Your approach to answering your research questions.

Literature review

Your literature review is the section of your report where you show what is already known about the area under investigation and demonstrate the need for your particular study. This is a significant section in your dissertation (30%) and you should allow plenty of time to carry out a thorough exploration of your focus topic and use it to help you identify a specific problem and formulate your research questions.

You should approach the literature review with the critical analysis dial turned up to full volume. This is not simply a description, list, or summary  of everything you have read. Instead, it is a synthesis of your reading, and should include analysis and evaluation of readings, evidence, studies and data, cases, real world applications and views/opinions expressed.  Your supervisor is looking for this detailed critical approach in your literature review, where you unpack sources, identify strengths and weaknesses and find gaps in the research.

In other words, your literature review is your opportunity to show the reader why your paper is important and your research is significant, as it addresses the gap or on-going issue you have uncovered.

You need to tell the reader what was done. This means describing the research methods and explaining your choice. This will include information on the following:

• Are your methods qualitative or quantitative... or both? And if so, why?
• Who (if any) are the participants?
• Are you analysing any documents, systems, organisations? If so what are they and why are you analysing them?
• What did you do first, second, etc?
• What ethical considerations are there?

It is a common style convention to write what was done rather than what you did, and write it so that someone else would be able to replicate your study.

Here you describe what you have found out. You need to identify the most significant patterns in your data, and use tables and figures to support your description. Your tables and figures are a visual representation of your findings, but remember to describe what they show in your writing. There should be no critical analysis in this part (unless you have combined results and discussion sections).

Here you show the significance of your results or findings. You critically analyse what they mean, and what the implications may be. Talk about any limitations to your study, evaluating the strengths and weaknesses of your own research, and make suggestions for further studies to build on your findings. In this section, your supervisor will expect you to dig deep into your findings and critically evaluate what they mean in relation to previous studies, theories, views and opinions.

This is a summary of your project, reminding the reader of the background to your study, your objectives, and showing how you met them. Do not include any new information that you have not discussed before.

This is the list of all the sources you have cited in your dissertation. Ensure you are consistent and follow the conventions for the particular referencing system you are using. (Note: you shouldn't include books you've read but do not appear in your dissertation).

Include any extra information that your reader may like to read. It should not be essential for your reader to read them in order to understand your dissertation. Your appendices should be labelled (e.g. Appendix A, Appendix B, etc). Examples of material for the appendices include detailed data tables (summarised in your results section), the complete version of a document you have used an extract from, etc.

Language of the Dissertation

Page and text requirements, body of text, tables, figures, and captions, dissertation acceptance certificate, copyright statement.

• Table of Contents

Front and Back Matter

Supplemental material, dissertations comprising previously published works, top ten formatting errors, further questions.

• Related Contacts and Forms

When preparing the dissertation for submission, students must follow strict formatting requirements. Any deviation from these requirements may lead to rejection of the dissertation and delay in the conferral of the degree.

The language of the dissertation is ordinarily English, although some departments whose subject matter involves foreign languages may accept a dissertation written in a language other than English.

Most dissertations are 100 to 300 pages in length. All dissertations should be divided into appropriate sections, and long dissertations may need chapters, main divisions, and subdivisions.

• 8½ x 11 inches, unless a musical score is included
• At least 1 inch for all margins
• Body of text: double spacing
• Block quotations, footnotes, and bibliographies: single spacing within each entry but double spacing between each entry
• Table of contents, list of tables, list of figures or illustrations, and lengthy tables: single spacing may be used

Fonts and Point Size

Use 10-12 point size. Fonts must be embedded in the PDF file to ensure all characters display correctly. 

Recommended Fonts

If you are unsure whether your chosen font will display correctly, use one of the following fonts: 

If fonts are not embedded, non-English characters may not appear as intended. Fonts embedded improperly will be published to DASH as-is. It is the student’s responsibility to make sure that fonts are embedded properly prior to submission. 

Instructions for Embedding Fonts

To embed your fonts in recent versions of Word, follow these instructions from Microsoft:

• Click the File tab and then click Options .
• In the left column, select the Save tab.
• Clear the Do not embed common system fonts check box.

For reference, below are some instructions from ProQuest UMI for embedding fonts in older file formats:

To embed your fonts in Microsoft Word 2010:

• In the File pull-down menu click on Options .
• Choose Save on the left sidebar.
• Check the box next to Embed fonts in the file.
• Click the OK button.
• Save the document.

Note that when saving as a PDF, make sure to go to “more options” and save as “PDF/A compliant”

To embed your fonts in Microsoft Word 2007:

• Click the circular Office button in the upper left corner of Microsoft Word.
• A new window will display. In the bottom right corner select Word Options . 
• Choose Save from the left sidebar.

Using Microsoft Word on a Mac:

Microsoft Word 2008 on a Mac OS X computer will automatically embed your fonts while converting your document to a PDF file.

If you are converting to PDF using Acrobat Professional (instructions courtesy of the Graduate Thesis Office at Iowa State University):  

• Open your document in Microsoft Word. 
• Click on the Adobe PDF tab at the top. Select "Change Conversion Settings." 
• Click on Advanced Settings. 
• Click on the Fonts folder on the left side of the new window. In the lower box on the right, delete any fonts that appear in the "Never Embed" box. Then click "OK." 
• If prompted to save these new settings, save them as "Embed all fonts." 
• Now the Change Conversion Settings window should show "embed all fonts" in the Conversion Settings drop-down list and it should be selected. Click "OK" again. 
• Click on the Adobe PDF link at the top again. This time select Convert to Adobe PDF. Depending on the size of your document and the speed of your computer, this process can take 1-15 minutes. 
• After your document is converted, select the "File" tab at the top of the page. Then select "Document Properties." 
• Click on the "Fonts" tab. Carefully check all of your fonts. They should all show "(Embedded Subset)" after the font name. 
•  If you see "(Embedded Subset)" after all fonts, you have succeeded.

The font used in the body of the text must also be used in headers, page numbers, and footnotes. Exceptions are made only for tables and figures created with different software and inserted into the document.

Tables and figures must be placed as close as possible to their first mention in the text. They may be placed on a page with no text above or below, or they may be placed directly into the text. If a table or a figure is alone on a page (with no narrative), it should be centered within the margins on the page. Tables may take up more than one page as long as they obey all rules about margins. Tables and figures referred to in the text may not be placed at the end of the chapter or at the end of the dissertation.

• Given the standards of the discipline, dissertations in the Department of History of Art and Architecture and the Department of Architecture, Landscape Architecture, and Urban Planning often place illustrations at the end of the dissertation.

Figure and table numbering must be continuous throughout the dissertation or by chapter (e.g., 1.1, 1.2, 2.1, 2.2, etc.). Two figures or tables cannot be designated with the same number. If you have repeating images that you need to cite more than once, label them with their number and A, B, etc. 

Headings should be placed at the top of tables. While no specific rules for the format of table headings and figure captions are required, a consistent format must be used throughout the dissertation (contact your department for style manuals appropriate to the field).

Captions should appear at the bottom of any figures. If the figure takes up the entire page, the caption should be placed alone on the preceding page, centered vertically and horizontally within the margins.

Each page receives a separate page number. When a figure or table title is on a preceding page, the second and subsequent pages of the figure or table should say, for example, “Figure 5 (Continued).” In such an instance, the list of figures or tables will list the page number containing the title. The word “figure” should be written in full (not abbreviated), and the “F” should be capitalized (e.g., Figure 5). In instances where the caption continues on a second page, the “(Continued)” notation should appear on the second and any subsequent page. The figure/table and the caption are viewed as one entity and the numbering should show correlation between all pages. Each page must include a header.

Landscape orientation figures and tables must be positioned correctly and bound at the top so that the top of the figure or table will be at the left margin. Figure and table headings/captions are placed with the same orientation as the figure or table when on the same page. When on a separate page, headings/captions are always placed in portrait orientation, regardless of the orientation of the figure or table. Page numbers are always placed as if the figure were vertical on the page.

If a graphic artist does the figures, Harvard Griffin GSAS will accept lettering done by the artist only within the figure. Figures done with software are acceptable if the figures are clear and legible. Legends and titles done by the same process as the figures will be accepted if they too are clear, legible, and run at least 10 or 12 characters per inch. Otherwise, legends and captions should be printed with the same font used in the text.

Original illustrations, photographs, and fine arts prints may be scanned and included, centered between the margins on a page with no text above or below.

Use of Third-Party Content

In addition to the student's own writing, dissertations often contain third-party content or in-copyright content owned by parties other than you, the student who authored the dissertation. The Office for Scholarly Communication recommends consulting the information below about fair use, which allows individuals to use in-copyright content, on a limited basis and for specific purposes, without seeking permission from copyright holders.

Because your dissertation will be made available for online distribution through DASH , Harvard's open-access repository, it is important that any third-party content in it may be made available in this way.

Fair Use and Copyright 

What is fair use?

Fair use is a provision in copyright law that allows the use of a certain amount of copyrighted material without seeking permission. Fair use is format- and media-agnostic. This means fair use may apply to images (including photographs, illustrations, and paintings), quoting at length from literature, videos, and music regardless of the format. 

How do I determine whether my use of an image or other third-party content in my dissertation is fair use?  

There are four factors you will need to consider when making a fair use claim.

1) For what purpose is your work going to be used?

• Nonprofit, educational, scholarly, or research use favors fair use. Commercial, non-educational uses, often do not favor fair use.
• A transformative use (repurposing or recontextualizing the in-copyright material) favors fair use. Examining, analyzing, and explicating the material in a meaningful way, so as to enhance a reader's understanding, strengthens your fair use argument. In other words, can you make the point in the thesis without using, for instance, an in-copyright image? Is that image necessary to your dissertation? If not, perhaps, for copyright reasons, you should not include the image.  

2) What is the nature of the work to be used?

• Published, fact-based content favors fair use and includes scholarly analysis in published academic venues. 
• Creative works, including artistic images, are afforded more protection under copyright, and depending on your use in light of the other factors, may be less likely to favor fair use; however, this does not preclude considerations of fair use for creative content altogether.

3) How much of the work is going to be used?  

• Small, or less significant, amounts favor fair use. A good rule of thumb is to use only as much of the in-copyright content as necessary to serve your purpose. Can you use a thumbnail rather than a full-resolution image? Can you use a black-and-white photo instead of color? Can you quote select passages instead of including several pages of the content? These simple changes bolster your fair use of the material.

4) What potential effect on the market for that work may your use have?

• If there is a market for licensing this exact use or type of educational material, then this weighs against fair use. If however, there would likely be no effect on the potential commercial market, or if it is not possible to obtain permission to use the work, then this favors fair use. 

For further assistance with fair use, consult the Office for Scholarly Communication's guide, Fair Use: Made for the Harvard Community and the Office of the General Counsel's Copyright and Fair Use: A Guide for the Harvard Community .

What are my options if I don’t have a strong fair use claim? 

Consider the following options if you find you cannot reasonably make a fair use claim for the content you wish to incorporate:

• Seek permission from the copyright holder. 
• Use openly licensed content as an alternative to the original third-party content you intended to use. Openly-licensed content grants permission up-front for reuse of in-copyright content, provided your use meets the terms of the open license.
• Use content in the public domain, as this content is not in-copyright and is therefore free of all copyright restrictions. Whereas third-party content is owned by parties other than you, no one owns content in the public domain; everyone, therefore, has the right to use it.

For use of images in your dissertation, please consult this guide to Finding Public Domain & Creative Commons Media , which is a great resource for finding images without copyright restrictions. 

Who can help me with questions about copyright and fair use?

Contact your Copyright First Responder . Please note, Copyright First Responders assist with questions concerning copyright and fair use, but do not assist with the process of obtaining permission from copyright holders.

Pages should be assigned a number except for the Dissertation Acceptance Certificate . Preliminary pages (abstract, table of contents, list of tables, graphs, illustrations, and preface) should use small Roman numerals (i, ii, iii, iv, v, etc.). All pages must contain text or images.  

Count the title page as page i and the copyright page as page ii, but do not print page numbers on either page .

For the body of text, use Arabic numbers (1, 2, 3, 4, 5, etc.) starting with page 1 on the first page of text. Page numbers must be centered throughout the manuscript at the top or bottom. Every numbered page must be consecutively ordered, including tables, graphs, illustrations, and bibliography/index (if included); letter suffixes (such as 10a, 10b, etc.) are not allowed. It is customary not to have a page number on the page containing a chapter heading.

• Check pagination carefully. Account for all pages.

A copy of the Dissertation Acceptance Certificate (DAC) should appear as the first page. This page should not be counted or numbered. The DAC will appear in the online version of the published dissertation. The author name and date on the DAC and title page should be the same. 

The dissertation begins with the title page; the title should be as concise as possible and should provide an accurate description of the dissertation. The author name and date on the DAC and title page should be the same. 

• Do not print a page number on the title page. It is understood to be page  i  for counting purposes only.

A copyright notice should appear on a separate page immediately following the title page and include the copyright symbol ©, the year of first publication of the work, and the name of the author:

© [ year ] [ Author’s Name ] All rights reserved.

Alternatively, students may choose to license their work openly under a  Creative Commons  license. The author remains the copyright holder while at the same time granting up-front permission to others to read, share, and (depending on the license) adapt the work, so long as proper attribution is given. (By default, under copyright law, the author reserves all rights; under a Creative Commons license, the author reserves some rights.)

• Do  not  print a page number on the copyright page. It is understood to be page  ii  for counting purposes only.

An abstract, numbered as page  iii , should immediately follow the copyright page and should state the problem, describe the methods and procedures used, and give the main results or conclusions of the research. The abstract will appear in the online and bound versions of the dissertation and will be published by ProQuest. There is no maximum word count for the abstract. 

• double-spaced
• left-justified
• indented on the first line of each paragraph
• The author’s name, right justified
• The words “Dissertation Advisor:” followed by the advisor’s name, left-justified (a maximum of two advisors is allowed)
• Title of the dissertation, centered, several lines below author and advisor

Dissertations divided into sections must contain a table of contents that lists, at minimum, the major headings in the following order:

• Front Matter
• Body of Text
• Back Matter

Front matter includes (if applicable):

• acknowledgements of help or encouragement from individuals or institutions
• a dedication
• a list of illustrations or tables
• a glossary of terms
• one or more epigraphs.

Back matter includes (if applicable):

• bibliography
• supplemental materials, including figures and tables
• an index (in rare instances).

Supplemental figures and tables must be placed at the end of the dissertation in an appendix, not within or at the end of a chapter. If additional digital information (including audio, video, image, or datasets) will accompany the main body of the dissertation, it should be uploaded as a supplemental file through ProQuest ETD . Supplemental material will be available in DASH and ProQuest and preserved digitally in the Harvard University Archives.

As a matter of copyright, dissertations comprising the student's previously published works must be authorized for distribution from DASH. The guidelines in this section pertain to any previously published material that requires permission from publishers or other rightsholders before it may be distributed from DASH. Please note:

• Authors whose publishing agreements grant the publisher exclusive rights to display, distribute, and create derivative works will need to seek the publisher's permission for nonexclusive use of the underlying works before the dissertation may be distributed from DASH.
• Authors whose publishing agreements indicate the authors have retained the relevant nonexclusive rights to the original materials for display, distribution, and the creation of derivative works may distribute the dissertation as a whole from DASH without need for further permissions.

It is recommended that authors consult their publishing agreements directly to determine whether and to what extent they may have transferred exclusive rights under copyright. The Office for Scholarly Communication (OSC) is available to help the author determine whether she has retained the necessary rights or requires permission. Please note, however, the Office of Scholarly Communication is not able to assist with the permissions process itself.

• Missing Dissertation Acceptance Certificate.  The first page of the PDF dissertation file should be a scanned copy of the Dissertation Acceptance Certificate (DAC). This page should not be counted or numbered as a part of the dissertation pagination.
• Conflicts Between the DAC and the Title Page.  The DAC and the dissertation title page must match exactly, meaning that the author name and the title on the title page must match that on the DAC. If you use your full middle name or just an initial on one document, it must be the same on the other document.  
• Abstract Formatting Errors. The advisor name should be left-justified, and the author's name should be right-justified. Up to two advisor names are allowed. The Abstract should be double spaced and include the page title “Abstract,” as well as the page number “iii.” There is no maximum word count for the abstract. 
•  The front matter should be numbered using Roman numerals (iii, iv, v, …). The title page and the copyright page should be counted but not numbered. The first printed page number should appear on the Abstract page (iii). 
• The body of the dissertation should be numbered using Arabic numbers (1, 2, 3, …). The first page of the body of the text should begin with page 1. Pagination may not continue from the front matter. 
• All page numbers should be centered either at the top or the bottom of the page.
• Figures and tables Figures and tables must be placed within the text, as close to their first mention as possible. Figures and tables that span more than one page must be labeled on each page. Any second and subsequent page of the figure/table must include the “(Continued)” notation. This applies to figure captions as well as images. Each page of a figure/table must be accounted for and appropriately labeled. All figures/tables must have a unique number. They may not repeat within the dissertation.
• Any figures/tables placed in a horizontal orientation must be placed with the top of the figure/ table on the left-hand side. The top of the figure/table should be aligned with the spine of the dissertation when it is bound. 
• Page numbers must be placed in the same location on all pages of the dissertation, centered, at the bottom or top of the page. Page numbers may not appear under the table/ figure.
• Supplemental Figures and Tables. Supplemental figures and tables must be placed at the back of the dissertation in an appendix. They should not be placed at the back of the chapter. 
• Permission Letters Copyright. permission letters must be uploaded as a supplemental file, titled ‘do_not_publish_permission_letters,” within the dissertation submission tool.
•  DAC Attachment. The signed Dissertation Acceptance Certificate must additionally be uploaded as a document in the "Administrative Documents" section when submitting in Proquest ETD . Dissertation submission is not complete until all documents have been received and accepted.
• Overall Formatting. The entire document should be checked after all revisions, and before submitting online, to spot any inconsistencies or PDF conversion glitches.
• You can view dissertations successfully published from your department in DASH . This is a great place to check for specific formatting and area-specific conventions.
• Contact the  Office of Student Affairs  with further questions.

Advice on planning and writing essays and dissertations

University essays differ from school essays in that they are less concerned with what you know and more concerned with how you construct an argument to answer the question. This means that the starting point for writing a strong essay is to first unpick the question and to then use this to plan your essay before you start putting pen to paper (or finger to keyboard).

A really good starting point for you are these short, downloadable Tips for Successful Essay Writing and Answering the Question resources. Both resources will help you to plan your essay, as well as giving you guidance on how to distinguish between different sorts of essay questions. 

You may find it helpful to watch this seven-minute video on six tips for essay writing which outlines how to interpret essay questions, as well as giving advice on planning and structuring your writing:

Different disciplines will have different expectations for essay structure and you should always refer to your Faculty or Department student handbook or course Canvas site for more specific guidance.

However, broadly speaking, all essays share the following features:

Essays need an introduction to establish and focus the parameters of the discussion that will follow. You may find it helpful to divide the introduction into areas to demonstrate your breadth and engagement with the essay question. You might define specific terms in the introduction to show your engagement with the essay question; for example, ‘This is a large topic which has been variously discussed by many scientists and commentators. The principal tension is between the views of X and Y who define the main issues as…’ Breadth might be demonstrated by showing the range of viewpoints from which the essay question could be considered; for example, ‘A variety of factors including economic, social and political, influence A and B. This essay will focus on the social and economic aspects, with particular emphasis on…..’

Watch this two-minute video to learn more about how to plan and structure an introduction:

The main body of the essay should elaborate on the issues raised in the introduction and develop an argument(s) that answers the question. It should consist of a number of self-contained paragraphs each of which makes a specific point and provides some form of evidence to support the argument being made. Remember that a clear argument requires that each paragraph explicitly relates back to the essay question or the developing argument.

• Conclusion: An essay should end with a conclusion that reiterates the argument in light of the evidence you have provided; you shouldn’t use the conclusion to introduce new information.
• References: You need to include references to the materials you’ve used to write your essay. These might be in the form of footnotes, in-text citations, or a bibliography at the end. Different systems exist for citing references and different disciplines will use various approaches to citation. Ask your tutor which method(s) you should be using for your essay and also consult your Department or Faculty webpages for specific guidance in your discipline. 

Essay writing in science subjects

If you are writing an essay for a science subject you may need to consider additional areas, such as how to present data or diagrams. This five-minute video gives you some advice on how to approach your reading list, planning which information to include in your answer and how to write for your scientific audience – the video is available here:

A PDF providing further guidance on writing science essays for tutorials is available to download.

Short videos to support your essay writing skills

There are many other resources at Oxford that can help support your essay writing skills and if you are short on time, the Oxford Study Skills Centre has produced a number of short (2-minute) videos covering different aspects of essay writing, including:

• Approaching different types of essay questions  
• Structuring your essay  
• Writing an introduction  
• Making use of evidence in your essay writing  
• Writing your conclusion

Extended essays and dissertations

Longer pieces of writing like extended essays and dissertations may seem like quite a challenge from your regular essay writing. The important point is to start with a plan and to focus on what the question is asking. A PDF providing further guidance on planning Humanities and Social Science dissertations is available to download.

Planning your time effectively

Try not to leave the writing until close to your deadline, instead start as soon as you have some ideas to put down onto paper. Your early drafts may never end up in the final work, but the work of committing your ideas to paper helps to formulate not only your ideas, but the method of structuring your writing to read well and conclude firmly.

Although many students and tutors will say that the introduction is often written last, it is a good idea to begin to think about what will go into it early on. For example, the first draft of your introduction should set out your argument, the information you have, and your methods, and it should give a structure to the chapters and sections you will write. Your introduction will probably change as time goes on but it will stand as a guide to your entire extended essay or dissertation and it will help you to keep focused.

The structure of  extended essays or dissertations will vary depending on the question and discipline, but may include some or all of the following:

• The background information to - and context for - your research. This often takes the form of a literature review.
• Explanation of the focus of your work.
• Explanation of the value of this work to scholarship on the topic.
• List of the aims and objectives of the work and also the issues which will not be covered because they are outside its scope.

The main body of your extended essay or dissertation will probably include your methodology, the results of research, and your argument(s) based on your findings.

The conclusion is to summarise the value your research has added to the topic, and any further lines of research you would undertake given more time or resources. 

Tips on writing longer pieces of work

Approaching each chapter of a dissertation as a shorter essay can make the task of writing a dissertation seem less overwhelming. Each chapter will have an introduction, a main body where the argument is developed and substantiated with evidence, and a conclusion to tie things together. Unlike in a regular essay, chapter conclusions may also introduce the chapter that will follow, indicating how the chapters are connected to one another and how the argument will develop through your dissertation.

“You will use a range of tenses depending on what you are writing about . ” Elizabeth M Fisher, Richard C Thompson, and Daniel Holtom,   Enjoy Writing Your Science Thesis Or Dissertation!

Tenses can be tricky to master. Even well respected journals differ in the guidance they give their authors for their use. However, their are some general conventions about what tenses are used in different parts of the report/dissertation. This page gives some advice on standard practice.

What tenses will you use?

There are exceptions however, most notably in the literature review where you will use a mixture of past , present and present perfect tenses (don't worry, that is explained below), when discussing the implications of your findings when the present tense is appropriate and in the recommendations where you are likely to use the future tense.

The tenses used as standard practice in each of these sections of your report are given and explained below.

In your abstract

You have some leeway with tense use in your abstract and guidance does vary which can sometimes be confusing. We recommend the following:

Describing the current situation and reason for your study

Mostly use the present tense,  i.e. "This is the current state of affairs and this is why this study is needed."

Occasionally, you may find the need to use something called the present perfect tense when you are describing things that happened in the past but are still relevant. The present perfect tense uses have/has and then the past participle of the verb i.e. Previous research on this topic has focused on... 

Describing the aims of your study

Here you have a choice. It is perfectly acceptable to use either the present or past tense,  i.e. "This study aims to..." or "This study aimed to..." 

Describing your methodology

Use the past tense to describe what you did, i.e. "A qualitative approach was used." "A survey was undertaken to ...". "The blood sample was analysed by..."

Describing your findings

Use the past tense to describe what you found as it is specific to your study, i.e. "The results showed that...", "The analysis indicated that..."

Suggesting the implications of your study

Use the present tense as even though your study took place in the past, your implications remain relevant in the present, i.e. Results revealed x which indicates that..."

Example abstract 

An example abstract with reasoning for the tenses chosen can be found at the bottom of this excellent blog post: 

Using the Present Tense and Past Tense When Writing an Abstract

In your methodology

The methodology is one of the easiest sections when it comes to tenses as you are explaining to your reader what you did. This is therefore almost exclusively written in the past tense.

Blood specimens were frozen at -80 o C.

A survey was designed using the Jisc Surveys tool.

Participants were purposefully selected.

The following search strategy was used to search the literature:

Very occasionally you may use the present tense if you are justifying a decision you have taken (as the justification is still valid, not just at the time you made the decision). For example: 

Purposeful sampling was used to ensure that a range of views were included. This sampling method maximises efficiency and validity as it identifies information-rich cases and ... (Morse & Niehaus, 2009).

In your discussion/conclusion

This will primarily be written in the present tense as you are generally discussing or making conclusions about the relevance of your findings at the present time. So you may write:

The findings of this research suggest that.../are potentially important because.../could open a new avenue for further research...

There will also be times when you use the past tense , especially when referring to part of your own research or previous published research research - but this is usually followed by something in the present tense to indicate the current relevance or the future tense to indicate possible future directions:

Analysis of the survey results found most respondents were not concerned with the processes, just the outcome. This suggests that managers should focus on...

These findings mirrored those of Cheung (2020), who also found that ESL pupils failed to understand some basic yet fundamental instructions. Addressing this will help ensure...

In your introduction

The introduction generally introduces what is in the rest of your document as is therefore describing the present situation and so uses the present tense :

Chapter 3  describes  the research methodology.

Depending on your discipline, your introduction may also review the literature so please also see that section below.

In your literature review

The findings of some literature may only be applicable in the specific circumstances that the research was undertaken and so need grounding to that study. Conversely, the findings of other literature may now be accepted as established knowledge. Also, you may consider the findings of older literature to be still relevant and relatively recent literature be already superseded. The tenses you write in will help to indicate a lot of this to the reader. In other words, you will use a mix of tenses in your review depending on what you are implying.

Findings only applicable in the specific circumstances

Use the past tense . For example: 

In an early study, Sharkey et al. (1991)  found  that isoprene emissions  were doubled  in leaves on sunnier sides of oak and aspen trees. 

Using the past tense indicates that you are not implying that isoprene emissions are always doubled on the sunnier side of the trees, just that is what was found in the Sharkey et al. study.

Findings that are still relevant or now established knowledge

Mostly use the present tense , unless the study is not recent and the authors are the subject of the sentence (which you should use very sparingly in a literature review) when you may need to use a mixture of the past and present. For example:

A narrowing of what 'graduateness' represents damages students’ abilities to thrive as they move through what will almost certainly be complex career pathways (Holmes, 2001).

Holmes (2001) argued strongly that a narrowing of what 'graduateness' represents damages  students’ abilities to thrive as they move through what will almost certainly be complex career pathways

Both of these imply that you think this is still the case (although it is perhaps more strongly implied in the first example). You may also want to use some academic caution too - such as writing 'may damage' rather than the more definite 'damages'.

Presenting your results

As with your methodology, your results section should be written in the past tense . This indicates that you are accepting that the results are specific to your research. Whilst they may have current implications, that part will not be considered until your discussion/conclusions section(s).

Four main themes were identified from the interview data.

There was a significant change in oxygen levels.

Like with the methodology, you will occasionally switch to present tense to write things like "Table 3.4 shows that ..." but generally, stick to the past tense.

In your recommendations

Not everyone will need to include recommendations and some may have them as part of the conclusions chapter. Recommendations are written in a mixture of the present tense and  future tense :

It is recommended that ward layout is adapted, where possible, to provide low-sensory bays for patients with autism. These will still be useable by all patients but...

Trump Leads in 5 Key States, as Young and Nonwhite Voters Express Discontent With Biden

A new set of Times/Siena polls, including one with The Philadelphia Inquirer, reveal an erosion of support for the president among young and nonwhite voters upset about the economy and Gaza.

SIENA COLLEGE POLL

Pennsylvania

Margin of error

If the 2024 presidential election were held today, who would you vote for if the candidates were Joe Biden and Donald Trump ?

By Nate Cohn

Donald J. Trump leads President Biden in five crucial battleground states, a new set of polls shows , as a yearning for change and discontent over the economy and the war in Gaza among young, Black and Hispanic voters threaten to unravel the president’s Democratic coalition.

The surveys by The New York Times, Siena College and The Philadelphia Inquirer found that Mr. Trump was ahead among registered voters in a head-to-head matchup against Mr. Biden in five of six key states: Michigan, Arizona, Nevada, Georgia and Pennsylvania. Mr. Biden led among registered voters in only one battleground state, Wisconsin.

[You can find the full results of the polls, including the exact questions that were asked, here . You can see answers to common questions about our polling process here .]

The race was closer among likely voters. Mr. Trump led in five states as well, but Mr. Biden edged ahead in Michigan while trailing only narrowly in Wisconsin and Pennsylvania. While Mr. Biden won all six of those states in 2020, victories in Pennsylvania, Michigan and Wisconsin would be enough for him to win re-election, provided he won everywhere else he did four years ago.

The results were similar in a hypothetical matchup that included minor-party candidates and the independent candidate Robert F. Kennedy Jr., who won an average of 10 percent of the vote across the six states and drew roughly equally from the two major-party candidates.

The findings are mostly unchanged since the last series of Times/Siena polls in battleground states in November. Since then, the stock market has gained 25 percent, Mr. Trump’s criminal trial in Manhattan has started, and the Biden campaign has unleashed tens of millions of dollars in advertisements across the battleground states.

The polls offer little indication that any of these developments have helped Mr. Biden, hurt Mr. Trump or quelled the electorate’s discontent. Instead, the surveys show that the cost of living, immigration, Israel’s war in Gaza and a desire for change continue to be a drag on the president’s standing. While Mr. Biden benefited from a burst of momentum in the wake of his State of the Union address in March, he continues to trail in the average of national and battleground state polls.

How support for the candidates differ

between registered and likely voters

The findings reveal widespread dissatisfaction with the state of the country and serious doubts about Mr. Biden’s ability to deliver major improvements to American life. A majority of voters still desire the return to normalcy promised by Mr. Biden in the last campaign, but voters in battleground states remain particularly anxious, unsettled and itching for change. Nearly 70 percent of voters say that the country’s political and economic systems need major changes — or even to be torn down entirely.

Only a sliver of Mr. Biden’s supporters — just 13 percent — believe that the president would bring major changes in his second term, while even many of those who dislike Mr. Trump grudgingly acknowledge that he would shake up an unsatisfying status quo.

The sense that Mr. Biden would do little to improve the nation’s fortunes has helped erode his standing among young, Black and Hispanic voters, who usually represent the foundation of any Democratic path to the presidency. The Times/Siena polls found that the three groups wanted fundamental changes to American society, not just a return to normalcy, and few believed that Mr. Biden would make even minor changes that would be good for the country.

Mr. Trump and Mr. Biden are essentially tied among 18-to-29-year-olds and Hispanic voters, even though each group gave Mr. Biden more than 60 percent of their vote in 2020. Mr. Trump also wins more than 20 percent of Black voters — a tally that would be the highest level of Black support for any Republican presidential candidate since the enactment of the Civil Rights Act of 1964.

The polls suggest that Mr. Trump’s strength among young and nonwhite voters has at least temporarily upended the electoral map, with Mr. Trump surging to a significant lead in Arizona, Georgia and Nevada — relatively diverse Sun Belt states where Black and Hispanic voters propelled Mr. Biden to signature victories in the 2020 election.

Mr. Biden nonetheless remains within striking distance. He has maintained most of his support among older and white voters, who are much less likely to demand fundamental changes to the system and far likelier to say that democracy is the most important issue for their vote. As a result, Mr. Biden is more competitive in the three relatively white Northern swing states: Michigan, Pennsylvania and Wisconsin.

The economy and the cost of living, however, remain the most important issues for one-quarter of voters — and a significant drag on Mr. Biden’s prospects. More than half of voters still believe that the economy is “poor,” down merely a single percentage point since November despite cooling inflation, an end to rate hikes and significant stock market gains.

Nearly 40 percent of Mr. Trump’s supporters said that the economy or the cost of living was the most important issue in the election, among them Jennifer Wright, a registered nurse in Sterling Heights, Mich. She supported Mr. Trump in 2016 and 2020, and to her the election comes down to one question: “Who is the best candidate who is going to help me be in a financial situation to retire?”

“Even me, as a registered nurse, I’m buying Kroger brand or store brand. I’m not buying Jif. We’ve all had to cut back,” she said.

The Biden administration’s insistence that the economy is faring well has fallen flat for many voters, including Jacob Sprague, 32, who works as a systems engineer in Reno, Nev. He says that he voted for Mr. Biden in 2020 but will not be doing so this time.

“It is concerning to me when I keep seeing press come out of the White House where they keep saying the economy is good,” Mr. Sprague said. “That’s really weird because I’m paying more on taxes and more on groceries and more on housing and more on fuel. So that doesn’t feel good.”

With less than six months to go until the election, there is still time for an improving economy to lift Mr. Biden’s standing. Historically, polls at this early stage have not been necessarily indicative of the outcome, and Mr. Trump’s breakthrough among traditionally Democratic young, Black and Hispanic voters may not rest on a solid foundation. His strength is concentrated among irregular, disengaged voters who do not pay close attention to politics and may not yet be tuned into the race. They may be prone to shift their views as the race gets underway.

In a finding that will frustrate Democrats, even as it presents opportunity for Mr. Biden, nearly 20 percent of voters blame him more than they do Mr. Trump for the Supreme Court’s decision in 2022 to overturn Roe v. Wade. They may be the kind of voters that the Biden campaign hopes to persuade as the campaign heats up.

The polls showed that abortion loomed as one of Mr. Trump’s biggest vulnerabilities. On average, 64 percent of voters in battleground states said that abortion should be always or mostly legal, including 44 percent of Mr. Trump’s own supporters.

In recent weeks, the Biden campaign has sought to emphasize Mr. Trump’s support for the Supreme Court justices who overturned Roe v. Wade. For now, though, voters preferred Mr. Biden over Mr. Trump to handle the issue of abortion by 11 points, 49 to 38 percent.

A bigger challenge for Mr. Biden than disengaged voters may ultimately be the disaffected and the disillusioned — those who desire fundamental changes to American society, or who believe that the political and economic systems need to be torn down altogether. Not long ago, these anti-system voters might have been reliably Democratic, but Mr. Trump’s anti-establishment populist brand of conservatism has flipped the usual political dynamic.

Seventy percent of voters believe that Mr. Trump will either bring major changes to the political or economic system or tear down the systems altogether, compared with 24 percent who expect the same from Mr. Biden. And while many voters express deep reservations about Mr. Trump personally, 43 percent of voters believe that he will bring good changes to the country, compared with 35 percent who think the changes will be bad.

Do you think the changes that [this candidate] would make would be good

Mr. Trump fares especially well among those who believe that the political and economic systems ought to be torn down, a group that represents about 15 percent of registered voters. He leads among these anti-system voters by 32 points, and the tear-it-down voters are especially likely to have defected from the president. In contrast, Mr. Biden retains nearly all of his 2020 supporters who believe only minor changes are necessary.

These change voters are not necessarily demanding a more ideologically progressive agenda. In the last Times/Siena poll of the same states, 11 percent of registered voters thought that Mr. Biden was not progressive or liberal enough. And while many liberal or progressive voters want major changes, relatively few of those voters are defecting from Mr. Biden.

Instead, Mr. Biden’s losses are concentrated among moderate and conservative Democratic-leaning voters, who nonetheless think that the system needs major changes or to be torn down altogether. Mr. Trump wins just 2 percent of Mr. Biden’s “very liberal” 2020 voters who think the system at least needs major changes, compared with 16 percent of those who are moderate or conservative.

One exception is Israel’s war in Gaza, an issue on which most of Mr. Biden’s challenge appears to come from his left. Around 13 percent of the voters who say they voted for Mr. Biden last time, but do not plan to do so again, said that his foreign policy or the war in Gaza was the most important issue to their vote. Just 17 percent of those voters reported sympathizing with Israel over the Palestinians.

Gerard Willingham, 30, works as a web administrator and lives in Riverdale, Ga. He voted for Mr. Biden in 2020, but he plans to vote for a third-party candidate in November because of the president’s response to the conflict in Gaza, the issue about which he cares most right now.

“I think it’s made quite a bit of difference in that it made me more heavily than in the past push toward voting for a third party, even if I feel that the candidates almost 100 percent won’t win,” Mr. Willingham said. “It’s starting to reach into my moral conscience, I guess.”

Mr. Trump’s trial in Manhattan, on charges that he falsified business records related to a hush-money payment to cover up an affair with the adult film star Stormy Daniels, was already underway when the polls began in late April. However, the survey offered little indication that the trial had damaged the former president’s political fortunes, at least so far. Just 29 percent of voters in battleground states said that they were paying “a lot” of attention to Mr. Trump’s legal woes, and 35 percent thought that the trial was likely to end in a conviction.

Alyce McFadden contributed reporting.

Here are the key things to know about how these polls were conducted:

We spoke with 4,097 registered voters in Arizona, Georgia, Michigan, Nevada, Pennsylvania and Wisconsin from April 28 to May 9, 2024.

Our polls are conducted by telephone, using live interviewers, in both English and Spanish. Nearly 95 percent of respondents were contacted on a cellphone for this poll. You can see the exact questions that were asked and the order in which they were asked here .

Voters are selected for the survey from a list of registered voters. The list contains information on the demographic characteristics of every registered voter, allowing us to make sure we reach the right number of voters of each party, race and region. For this set of polls, we placed nearly 500,000 calls to about 410,000 voters.

To further ensure that the results reflect the entire voting population, not just those willing to take a poll, we give more weight to respondents from demographic groups underrepresented among survey respondents, like people without a college degree. You can see more information about the characteristics of our respondents and the weighted sample on the methodology page , under “Composition of the Sample.”

When the states are joined together, the margin of sampling error among registered voters is plus or minus 1.8 percentage points. Each state poll has a margin of error ranging from plus or minus 3.6 points in Pennsylvania to plus or minus 4.6 points in Georgia. In theory, this means that the results should reflect the views of the overall population most of the time, though many other challenges create additional sources of error. When computing the difference between two values — such as a candidate’s lead in a race — the margin of error is twice as large.

Published on 25 February 2019 by Shona McCombes . Revised on 10 October 2022.

Your research methodology discusses and explains the data collection and analysis methods you used in your research. A key part of your thesis, dissertation, or research paper, the methodology chapter explains what you did and how you did it, allowing readers to evaluate the reliability and validity of your research.

It should include:

• The type of research you conducted
• How you collected and analysed your data
• Any tools or materials you used in the research
• Why you chose these methods
• Your methodology section should generally be written in the past tense .
• Academic style guides in your field may provide detailed guidelines on what to include for different types of studies.
• Your citation style might provide guidelines for your methodology section (e.g., an APA Style methods section ).

Correct my document today

Your methods section is your opportunity to share how you conducted your research and why you chose the methods you chose. It’s also the place to show that your research was rigorously conducted and can be replicated .

It gives your research legitimacy and situates it within your field, and also gives your readers a place to refer to if they have any questions or critiques in other sections.

You can start by introducing your overall approach to your research. You have two options here.

Option 1: Start with your “what”

What research problem or question did you investigate?

• Aim to describe the characteristics of something?
• Explore an under-researched topic?
• Establish a causal relationship?

And what type of data did you need to achieve this aim?

• Quantitative data , qualitative data , or a mix of both?
• Primary data collected yourself, or secondary data collected by someone else?
• Experimental data gathered by controlling and manipulating variables, or descriptive data gathered via observations?

Option 2: Start with your “why”

Depending on your discipline, you can also start with a discussion of the rationale and assumptions underpinning your methodology. In other words, why did you choose these methods for your study?

• Why is this the best way to answer your research question?
• Is this a standard methodology in your field, or does it require justification?
• Were there any ethical considerations involved in your choices?
• What are the criteria for validity and reliability in this type of research ?

Once you have introduced your reader to your methodological approach, you should share full details about your data collection methods .

Quantitative methods

In order to be considered generalisable, you should describe quantitative research methods in enough detail for another researcher to replicate your study.

Here, explain how you operationalised your concepts and measured your variables. Discuss your sampling method or inclusion/exclusion criteria, as well as any tools, procedures, and materials you used to gather your data.

Surveys Describe where, when, and how the survey was conducted.

• How did you design the questionnaire?
• What form did your questions take (e.g., multiple choice, Likert scale )?
• Were your surveys conducted in-person or virtually?
• What sampling method did you use to select participants?
• What was your sample size and response rate?

Experiments Share full details of the tools, techniques, and procedures you used to conduct your experiment.

• How did you design the experiment ?
• How did you recruit participants?
• How did you manipulate and measure the variables ?
• What tools did you use?

Existing data Explain how you gathered and selected the material (such as datasets or archival data) that you used in your analysis.

• Where did you source the material?
• How was the data originally produced?
• What criteria did you use to select material (e.g., date range)?

The survey consisted of 5 multiple-choice questions and 10 questions measured on a 7-point Likert scale.

The goal was to collect survey responses from 350 customers visiting the fitness apparel company’s brick-and-mortar location in Boston on 4–8 July 2022, between 11:00 and 15:00.

Here, a customer was defined as a person who had purchased a product from the company on the day they took the survey. Participants were given 5 minutes to fill in the survey anonymously. In total, 408 customers responded, but not all surveys were fully completed. Due to this, 371 survey results were included in the analysis.

Qualitative methods

In qualitative research , methods are often more flexible and subjective. For this reason, it’s crucial to robustly explain the methodology choices you made.

Be sure to discuss the criteria you used to select your data, the context in which your research was conducted, and the role you played in collecting your data (e.g., were you an active participant, or a passive observer?)

Interviews or focus groups Describe where, when, and how the interviews were conducted.

• How did you find and select participants?
• How many participants took part?
• What form did the interviews take ( structured , semi-structured , or unstructured )?
• How long were the interviews?
• How were they recorded?

Participant observation Describe where, when, and how you conducted the observation or ethnography .

• What group or community did you observe? How long did you spend there?
• How did you gain access to this group? What role did you play in the community?
• How long did you spend conducting the research? Where was it located?
• How did you record your data (e.g., audiovisual recordings, note-taking)?

Existing data Explain how you selected case study materials for your analysis.

• What type of materials did you analyse?
• How did you select them?

In order to gain better insight into possibilities for future improvement of the fitness shop’s product range, semi-structured interviews were conducted with 8 returning customers.

Here, a returning customer was defined as someone who usually bought products at least twice a week from the store.

Surveys were used to select participants. Interviews were conducted in a small office next to the cash register and lasted approximately 20 minutes each. Answers were recorded by note-taking, and seven interviews were also filmed with consent. One interviewee preferred not to be filmed.

Mixed methods

Mixed methods research combines quantitative and qualitative approaches. If a standalone quantitative or qualitative study is insufficient to answer your research question, mixed methods may be a good fit for you.

Mixed methods are less common than standalone analyses, largely because they require a great deal of effort to pull off successfully. If you choose to pursue mixed methods, it’s especially important to robustly justify your methods here.

Prevent plagiarism, run a free check.

Next, you should indicate how you processed and analysed your data. Avoid going into too much detail: you should not start introducing or discussing any of your results at this stage.

In quantitative research , your analysis will be based on numbers. In your methods section, you can include:

• How you prepared the data before analysing it (e.g., checking for missing data , removing outliers , transforming variables)
• Which software you used (e.g., SPSS, Stata or R)
• Which statistical tests you used (e.g., two-tailed t test , simple linear regression )

In qualitative research, your analysis will be based on language, images, and observations (often involving some form of textual analysis ).

Specific methods might include:

• Content analysis : Categorising and discussing the meaning of words, phrases and sentences
• Thematic analysis : Coding and closely examining the data to identify broad themes and patterns
• Discourse analysis : Studying communication and meaning in relation to their social context

Mixed methods combine the above two research methods, integrating both qualitative and quantitative approaches into one coherent analytical process.

Above all, your methodology section should clearly make the case for why you chose the methods you did. This is especially true if you did not take the most standard approach to your topic. In this case, discuss why other methods were not suitable for your objectives, and show how this approach contributes new knowledge or understanding.

In any case, it should be overwhelmingly clear to your reader that you set yourself up for success in terms of your methodology’s design. Show how your methods should lead to results that are valid and reliable, while leaving the analysis of the meaning, importance, and relevance of your results for your discussion section .

• Quantitative: Lab-based experiments cannot always accurately simulate real-life situations and behaviours, but they are effective for testing causal relationships between variables .
• Qualitative: Unstructured interviews usually produce results that cannot be generalised beyond the sample group , but they provide a more in-depth understanding of participants’ perceptions, motivations, and emotions.
• Mixed methods: Despite issues systematically comparing differing types of data, a solely quantitative study would not sufficiently incorporate the lived experience of each participant, while a solely qualitative study would be insufficiently generalisable.

Remember that your aim is not just to describe your methods, but to show how and why you applied them. Again, it’s critical to demonstrate that your research was rigorously conducted and can be replicated.

1. Focus on your objectives and research questions

The methodology section should clearly show why your methods suit your objectives  and convince the reader that you chose the best possible approach to answering your problem statement and research questions .

2. Cite relevant sources

Your methodology can be strengthened by referencing existing research in your field. This can help you to:

• Show that you followed established practice for your type of research
• Discuss how you decided on your approach by evaluating existing research
• Present a novel methodological approach to address a gap in the literature

3. Write for your audience

Consider how much information you need to give, and avoid getting too lengthy. If you are using methods that are standard for your discipline, you probably don’t need to give a lot of background or justification.

Regardless, your methodology should be a clear, well-structured text that makes an argument for your approach, not just a list of technical details and procedures.

Methodology refers to the overarching strategy and rationale of your research. Developing your methodology involves studying the research methods used in your field and the theories or principles that underpin them, in order to choose the approach that best matches your objectives.

Methods are the specific tools and procedures you use to collect and analyse data (e.g. interviews, experiments , surveys , statistical tests ).

In a dissertation or scientific paper, the methodology chapter or methods section comes after the introduction and before the results , discussion and conclusion .

Depending on the length and type of document, you might also include a literature review or theoretical framework before the methodology.

Quantitative research deals with numbers and statistics, while qualitative research deals with words and meanings.

Quantitative methods allow you to test a hypothesis by systematically collecting and analysing data, while qualitative methods allow you to explore ideas and experiences in depth.

A sample is a subset of individuals from a larger population. Sampling means selecting the group that you will actually collect data from in your research.

For example, if you are researching the opinions of students in your university, you could survey a sample of 100 students.

Statistical sampling allows you to test a hypothesis about the characteristics of a population. There are various sampling methods you can use to ensure that your sample is representative of the population as a whole.

What is Memorial Day? The true meaning of why we celebrate the federal holiday

For many Americans, Memorial Day is more than a long weekend and an unofficial start to the summer season. The real meaning of the holiday is meant to honor all U.S. soldiers who have died serving their country.

Originally called Decoration Day, Memorial Day's history goes back to the Civil War. It was was declared a national holiday by Congress in 1971, according to the U.S. Department of Veterans' Affairs.

Although Veterans Day in November also honors military service members, Memorial Day differs by honoring all military members who have died while serving in U.S. forces in any current or previous wars.

The late-May holiday has also evolved into an opportunity for Americans to head to the beach or lake , travel to see friends and family , or even catch a Memorial Day parade .

Here's what to know about the history and the reason behind why we observe Memorial Day.

When is Memorial Day?

One of 11 federal holidays recognized in the U.S., Memorial Day is always observed on the last Monday of May. This year, the holiday falls on Monday, May 27.

Why do we celebrate Memorial Day?  

The origins of the holiday can be traced back to local observances for soldiers with neglected gravesites during the Civil War.

The first observance of what would become Memorial Day, some historians think, took place in Charleston, South Carolina at the site of a horse racing track that Confederates had turned into a prison holding Union prisoners. Blacks in the city organized a burial of deceased Union prisoners and built a fence around the site, Yale historian David Blight wrote in  The New York Times  in 2011.

Then on May 1, 1865, they held an event there including a parade – Blacks who fought in the Civil War participated – spiritual readings and songs, and picnicking. A commemorative marker was erected there in 2010.

One of the first Decoration Days was held in Columbus, Mississippi, on April 25, 1866 by women who decorated graves of Confederate soldiers who perished in the battle at Shiloh with flowers. On May 5, 1868, three years after the end of the Civil War, the tradition of placing flowers on veterans’ graves was continued by the establishment of Decoration Day by an organization of Union veterans, the Grand Army of the Republic. 

General Ulysses S. Grant presided over the first large observance, a crowd of about 5,000 people, at Arlington National Cemetery in Virginia on May 30, 1873.

This tradition continues to thrive in cemeteries of all sizes across the country. 

Until World War I, Civil War soldiers were solely honored on this holiday. Now, all Americans who’ve served are observed. 

At least 25 places in the North and the South claim to be the birthplace of Memorial Day. Some states that claim ownership of the origins include Illinois, Georgia, Virginia, and Pennsylvania, according to Veterans Affairs.

Despite conflicting claims, the U.S. Congress and President Lyndon Johnson declared Waterloo, New York, as the “birthplace” of Memorial Day on May 30, 1966, after Governor Nelson Rockefeller's declaration that same year. The New York community formally honored local veterans May 5, 1866 by closing businesses and lowering flags at half-staff. 

Why is Memorial Day in May? 

The day that we celebrate Memorial Day is believed to be influenced by Illinois U.S. Representative John A. Logan, who was elected to the U.S. House of Representatives as a Democrat in November 1858, and served as an officer during the Mexican War.

It is said that Logan, a staunch defender of the Union, believed Memorial Day should occur when flowers are in full bloom across the country, according to the  National Museum of the U.S. Army.

Congress passed an act making May 30 a holiday in the District of Columbia in 1888,  according to the U.S. Congressional Research Service.

In 2000, the National Moment of Remembrance Act – which created the White House Commission on the National Moment of Remembrance and encourages all to pause at 3 p.m. local time on Memorial Day for a minute of silence – was signed into law by Congress and the President.

What is the difference between Memorial Day and Veterans Day?

Memorial Day and Veterans Day both honor the sacrifices made by U.S. veterans, but the holidays serve different purposes.

Veterans Day, originally called “Armistice Day,” is a younger holiday established in 1926 as a way to commemorate all those who had served in the U.S. armed forces during World War I.

Memorial Day honors all those who have died.

In a baffling closing argument, Trump attorney Todd Blanche used DA's evidence against his own client

• In closings Tuesday, Trump's lawyer Todd Blanche tried the classic "but if he did do it" defense.
• If Trump did falsify documents, he didn't do it with the required criminal intent, Blanche argued.
• He showed jurors three prosecution exhibits where Trump acknowledged the hush-money reimbursement.

It's the classic defense closing argument: My client didn't do it, ladies and gentlemen — but if he did do it, it wasn't intentional.

This is the argument that former President Donald Trump's lawyer Todd Blanche tried out Tuesday on the hush-money jury in Manhattan.

Yes, Blanche spent the bulk of his arguments denying that Trump committed the crimes he's accused of.

Prosecutors say Trump falsified 34 business records to hide a year's worth of reimbursement payments to his then-attorney Michael Cohen , who had fronted a $130,000 hush-money payment to the porn star Stormy Daniels.

Trump was not involved in any such conspiracy to influence the 2016 election, Blanche told jurors Tuesday — during a three-hour summation where he walked them through a more than 180-part slideshow presentation ahead of the start of their deliberations on Wednesday.

But if he was involved, there was no intent to commit fraud, Blanche argued. How could there be, he asked, when Trump freely and repeatedly acknowledged reimbursing Cohen?

Blanche then showed the jury three exhibits from the prosecution's case.

The exhibits — showing a tax form, a tweet, and a government ethics form — were shown on the courtroom's display screens.

Each bolsters the prosecution's case: Trump knew full well that the $130,000 he paid Cohen in installments throughout 2017 was for reimbursement, not legal fees, as his business-record entries falsely claimed.

"The government has to prove to you that President Trump caused these entries — even if they were false — with an intent to defraud," Blanche told jurors.

"Where is the intent to defraud on the part of President Trump?" the lawyer asked the jury.

Prosecutors must demonstrate Trump had an intent to defraud in order for them to prove first-degree falsifying of business records, which Trump is accused of doing 34 times throughout 2017, including when he personally signed nine of Cohen's reimbursement checks.

In his own closing argument, Joshua Steinglass, an assistant district attorney, said Trump had to have approved the reimbursement scheme.

Cohen would never have fronted the $130,000 without his micromanaging boss' preapproval and guarantee of repayment, Steinglass argued.

"Michael Cohen had 130,000 reasons to get Mr. Trump's sign-off," the prosecutor told jurors.

During his closing argument, Blanche angered the judge by telling jurors that "you cannot send somebody to prison based on what Michael Cohen is saying."

Jurors are supposed to weigh only the facts in their deliberations — not the potential punishment.

"That was outrageous, Mr. Blanche," Justice Juan Merchan of the New York Supreme Court told Blanche after jurors were dismissed for lunch.

"Someone who's been a prosecutor as long as you have, and a defense lawyer as long as you have, knows it's highly inappropriate," the judge said.

"It's simply not allowed, period," the judge added. He gave a curative instruction to the jury, saying that Blanche's comment was "improper" and that if Trump was convicted, "a prison sentence is not required." Falsifying business records carries a sentence of anywhere from zero jail to four years in prison.

Here are the three exhibits that Blanche displayed for jurors as "proof" that Trump had nothing to hide and therefore could not have intended to defraud anyone.

But each is highly incriminating of Trump, prosecutors have argued.

1. A 1099 tax form from 2017

The Trump Organization — and Trump as an individual — reported that it paid Cohen a total of $420,000 in income in 2017.

Related stories

Prosecutors say this is the sum Trump's then-CFO, Allen Weisselberg, calculated would be reimbursed for Cohen's hush-money outlay, plus taxes and other money Trump owed him.

Why would Trump announce to the IRS "if there was some deep-rooted intent to defraud on the part of President Trump?" Blanche asked jurors.

But the 1099s are "false," Steinglass, the prosecutor, told jurors in his closing arguments, which went on for five hours, ending at 8 p.m.

The 1099s demonstrate that Trump "filled out phony forms" to report income for Cohen that did not exist, Steinglass said — "because it wasn't income; it was reimbursement."

2. A 2018 tweet

On May 3, 2018, Trump posted a somewhat garbled tweet that said the payments he'd made to Cohen throughout 2017 were, in his word, "reimbursement."

This tweet was posted just five months after Trump signed the last of nine $35,000 checks to Cohen. Each check was labeled "RETAINER."

3. A government ethics form

Finally, during closing arguments, Blanche showed jurors what's called an Executive Branch Personnel Public Financial Disclosure Report for the year 2017. This was the then-president's mandatory disclosure of his assets and liabilities.

Under "Liabilities" — which is the section where Trump must list the money he's borrowed — Trump certified that in 2017, he "fully reimbursed" Cohen an interest-free sum of between $100,000 and $250,000.

"President Trump tweeted what happened when it came out" and then signed a government ethics form that also acknowledged the reimbursement, Blanche told jurors Tuesday.

"That's not evidence of any intent to defraud," Blanche said.

But prosecutors have argued this form shows Trump knew the money he paid Cohen was reimbursement for money lent — the Daniels hush money.

Cohen the 'GLOAT'

Blanche spent most of his summation impugning the credibility of Cohen, whose testimony is key to the prosecution case .

Cohen is "literally like an MVP of liars," the defense lawyer told jurors. Two jurors — a woman in the front row and a man in the back row — smiled when Blanche went on to call Cohen "the GLOAT," for "greatest liar of all time."

The district attorney's reliance on Cohen's testimony demonstrates the weakness of the prosecution's case, Blanche said. He said that Cohen committed "per-ju-ry" — stressing every syllable — on the witness stand and was "the human embodiment of reasonable doubt."

"You should want and expect more than the testimony of Michael Cohen," he said.

Blanche sidestepped the most pivotal documents in the case, handwritten notes from Weisselberg and the Trump Organization's then-comptroller, Jeffrey McConney , that appeared to explain how Cohen would be repaid for hush money in $35,000 payments, including a "gross up" to cover taxes.

Blanche claimed that if the document was truly proof of an illegal conspiracy, the Trump Organization would have destroyed it instead of keeping it in a filing cabinet — from which they were ultimately turned over to prosecutors.

Steinglass countered that it must have been hard for Blanche to make that argument "with a straight face," saying the illegal conspiracy was laid out "in the document itself."

"These documents are so damning that you almost have to laugh," he said.

At the beginning of the prosecution's closing argument on Tuesday afternoon, Steinglass said that while Cohen may have a track record of dishonesty , he had come clean and "been consistently explaining the facts of this case for six years."

"We didn't choose Michael Cohen. We didn't pick him up at the witness store," Steinglass said. "The defendant chose Michael Cohen because of his willingness to lie."

Blanche had also criticized prosecutors for spending time teasing out testimony from Daniels, which he said wasn't critical to the criminal charges, related to falsified documents. Prosecutors, the defense lawyer said, just wanted to "embarrass" Trump.

Daniels' vivid and "cringeworthy" details "ring true" and were "uncomfortable," which is why they were so important, Steinglass said. Trump wanted to cover up her story to influence the election, he added.

"That's kind of the point," Steinglass said. "That's the display the defendant didn't want the American people to see."

Trump didn't pay $130,000 to cover up a photo of him and Daniels on a golf course — but to cover up a scandal, Steinglass said.

"Stormy Daniels is the motive," he said.

Want to use ChatGPT to help prepare for court? This is what lawyers say you should and shouldn't do

With a few quick prompts, an artificial intelligence chatbot can write a song, tell you a joke or teach you a new skill — and increasingly, people are using it to help represent themselves in court.

It's led Queensland to follow in the footsteps of Victoria, New Zealand and England in issuing guidelines on how people who aren't lawyers can use generative AI like ChatGPT responsibly.

Earlier this year in Queensland's Supreme Court, Justice Elizabeth Wilson noted a man representing himself used the program to add "flourish" to his submissions.

The plaintiff, who was awarded more than $85,000 in damages after a motorbike crash, vouched for the accuracy of his submissions, with Justice Wilson adding that ChatGPT "assisted in their organisational structure".

The guidelines released by Queensland Courts states generative AI is not a "substitute for a qualified lawyer and cannot give you tailored legal advice".

"Currently available Generative AI chatbots have been known to provide inaccurate information on Australian law," it states.

"If you choose to use Generative AI chatbots to help you with your court case, you should not rely on this as your sole or main source of legal information."

AI not being 'widely used' yet

The purpose of the guidelines is to draw awareness to the strengths and limitations of chatbots. 

That's according to Queensland Chief Justice Helen Bowskill, who says the guidelines also highlight the importance of checking for accuracy and being aware of confidentiality.

"Its capacity for effective use in court proceedings is not yet fully known, but based on what we do already know it was considered appropriate to issue guidelines for the responsible use of generative AI by non-lawyers," she says.

Chief Justice Bowskill says the most likely way AI is currently being used is for legal research, but it is hard to say what the future will hold.

"It is very much a matter of waiting and seeing how the technology develops."

The court didn't consider it necessary to publish guidelines for lawyers, with law societies thought to be better placed to address the broader implications of using AI.

Queensland University of Technology professor Anna Huggins provided recommendations to the Supreme Court judges who prepared the guidance. 

She says harnessing the benefits of AI tools, while minimising their potential risks, requires a thoughtful approach to ensure it's used responsibly and ethically.

"It's beneficial for new users of generative AI to seek to develop a basic understanding of the nature of the AI tool they are using, the dataset it's trained on, and its strengths and limitations for particular tasks," she says.

"Developing skills in writing and augmenting prompts, or instructions, for generative AI chatbots is valuable to enhance the quality of outputs."

Professor Huggins says although generative AI can help with some legal tasks, it's important for users to check the accuracy of the information is provides before relying on it.

What's the positives of having access to AI chatbots?

Queensland University of Technology associate professor Michael Guihot says generative AI can improve access to justice for those who can't afford to hire a lawyer.

"If people who previously couldn't access justice, had a problem with language or couldn't put their words into the required language, for a Statement of Claim for example, can do it now using ChatGPT I think that is a good thing," he says. 

"If we can make people speak in the language they have to in court and clear, logical structured arguments that's good thing."

Dr Guihot says he believes the benefits outweigh the potential for mistakes. 

"The risk is that we might get some citations wrong, or we might get a Statement of Claim that is not as logical as it should be but that can be addressed, rather than it doesn't go to court in the first place at all," he says.

"It may be just that we have a couple of more people who can access justice, and they've got a clear tool to help them logically structure their argument." 

He says lawyers shouldn't be making use of chatbots in the same way, but rather as a springboard to then use their own skill and judgement. 

In the United States, lawyers have been caught for relying on ChatGPT to find legal precedents, with the chatbot fabricating cases.

Where do 'real lawyers' come in?

Queensland Law Society (QLS) chief executive Matt Dunn says AI isn't disrupting the profession enormously, but has the potential to with its ability to allow lawyers to work smarter and faster.

"AI is great to be able to find information and to be able to start the job, but there's still a role for real lawyers with real experience to be able to understand the facts, understand the law, apply the law to a person's individual facts, and then come up with an informed outcome," he says.  

"It's a very big matter of discussion, and everyone's talking about it and looking at it and trying to figure out how to use it in a way that's appropriate and safe and respects all of the ethical and confidentiality obligations that practitioners have."

He says AI is useful for people to organise information, rewrite summaries, change the tone and for put the chronology of events in order.

However, his favourite analogy to explain the ability of AI is that it is like asking an actor who has played a doctor for medical advice. 

"Sometimes they'll be quite right in what they say, and it'll sound really convincing, but they're not always going to be right," Mr Dunn said.  

Mr Dunn says QLS will be releasing separate guidance on the use of AI for lawyers.

"We want our practitioners to be experimenting and trying things, but they also need to be doing it in a way that's conscious of some of the limitations," he says.

The voice in your head may help you recall and process words. But what if you don’t have one?

Can you imagine hearing yourself speak? A voice inside your head – perhaps reciting a shopping list or a phone number? What would life be like if you couldn’t?

Some people, including me, cannot have imagined visual experiences. We cannot close our eyes and conjure an experience of seeing a loved one’s face, or imagine our lounge room layout – to consider if a new piece of furniture might fit in it. This is called “ aphantasia ”, from a Greek phrase where the “a” means without, and “phantasia” refers to an image. Colloquially, people like myself are often referred to as having a “blind mind”.

While most attention has been given to the inability to have imagined visual sensations, aphantasics can lack other imagined experiences. We might be unable to experience imagined tastes or smells. Some people cannot imagine hearing themselves speak.

A recent study has advanced our understanding of people who cannot imagine hearing their own internal monologue. Importantly, the authors have identified some tasks that such people are more likely to find challenging.

What the study found

Researchers at the University of Copenhagen in Denmark and at the University of Wisconsin-Madison in the United States recruited 93 volunteers . They included 46 adults who reported low levels of inner speech and 47 who reported high levels.

Both groups were given challenging tasks: judging if the names of objects they had seen would rhyme and recalling words. The group without an inner monologue performed worse. But differences disappeared when everyone could say words aloud.

Importantly, people who reported less inner speech were not worse at all tasks. They could recall similar numbers of words when the words had a different appearance to one another. This negates any suggestion that aphants (people with aphantasia) simply weren’t trying or were less capable.

A welcome validation

The study provides some welcome evidence for the lived experiences of some aphants, who are still often told their experiences are not different, but rather that they cannot describe their imagined experiences. Some people feel anxiety when they realise other people can have imagined experiences that they cannot. These feelings may be deepened when others assert they are merely confused or inarticulate.

In my own aphantasia research I have often quizzed crowds of people on their capacity to have imagined experiences.

Questions about the capacity to have imagined visual or audio sensations tend to be excitedly endorsed by a vast majority, but questions about imagined experiences of taste or smell seem to cause more confusion. Some people are adamant they can do this, including a colleague who says he can imagine what combinations of ingredients will taste like when cooked together. But other responses suggest subtypes of aphantasia may prove to be more common than we realise.

The authors of the recent study suggest the inability to imagine hearing yourself speak should be referred to as “anendophasia”, meaning without inner speech. Other authors had suggested anauralia (meaning without auditory imagery). Still other researchers have referred to all types of imagined sensation as being different types of “imagery”.

Having consistent names is important. It can help scientists “talk” to one another to compare findings. If different authors use different names, important evidence can be missed.

We have more than 5 senses

Debate continues about how many senses humans have, but some scientists reasonably argue for a number greater than 20 .

In addition to the five senses of sight, smell, taste, touch and hearing, lesser known senses include thermoception (our sense of heat) and proprioception (awareness of the positions of our body parts). Thanks to proprioception, most of us can close our eyes and touch the tip of our index finger to our nose. Thanks to our vestibular sense, we typically have a good idea of which way is up and can maintain balance.

It may be tempting to give a new name to each inability to have a given type of imagined sensation. But this could lead to confusion. Another approach would be to adapt phrases that are already widely used. People who are unable to have imagined sensations commonly refer to ourselves as “aphants”. This could be adapted with a prefix, such as “audio aphant”. Time will tell which approach is adopted by most researchers.

Why we should keep investigating

Regardless of the names we use, the study of multiple types of inability to have an imagined sensation is important. These investigations could reveal the essential processes in human brains that bring about a conscious experience of an imagined sensation.

In time, this will not only lead to a better understanding of the diversity of humans, but may help uncover how human brains can create any conscious sensation. This question – how and where our conscious feelings are generated – remains one of the great mysteries of science.

When medical devices such as pacemakers are implanted in the body, they usually provoke an immune response that leads to buildup of scar tissue around the implant. This scarring, known as fibrosis, can interfere with the devices’ function and may require them to be removed.

In an advance that could prevent that kind of device failure, MIT engineers have found a simple and general way to eliminate fibrosis by coating devices with a hydrogel adhesive. This adhesive binds the devices to tissue and prevents the immune system from attacking it.

“The dream of many research groups and companies is to implant something into the body that over the long term the body will not see, and the device can provide therapeutic or diagnostic functionality. Now we have such an ‘invisibility cloak,’ and this is very general: There’s no need for a drug, no need for a special polymer,” says Xuanhe Zhao, an MIT professor of mechanical engineering and of civil and environmental engineering.

The adhesive that the researchers used in this study is made from cross-linked polymers called hydrogels, and is similar to a surgical tape they previously developed to help seal internal wounds. Other types of hydrogel adhesives can also protect against fibrosis, the researchers found, and they believe this approach could be used for not only pacemakers but also sensors or devices that deliver drugs or therapeutic cells.

Zhao and Hyunwoo Yuk SM ’16, PhD ’21, a former MIT research scientist who is now the chief technology officer at SanaHeal, are the senior authors of the study, which appears today in Nature . MIT postdoc Jingjing Wu is the lead author of the paper.

Preventing fibrosis

In recent years, Zhao’s lab has developed adhesives for a variety of medical applications, including double-sided and single-sided tapes that could be used to heal surgical incisions or internal injuries. These adhesives work by rapidly absorbing water from wet tissues, using polyacrylic acid, an absorbent material used in diapers. Once the water is cleared, chemical groups called NHS esters embedded in the polyacrylic acid form strong bonds with proteins at the tissue surface. This process takes about five seconds.

Several years ago, Zhao and Yuk began exploring whether this kind of adhesive could also help keep medical implants in place and prevent fibrosis from occurring.

To test this idea, Wu coated polyurethane devices with their adhesive and implanted them on the abdominal wall, colon, stomach, lung, or heart of rats. Weeks later, they removed the device and found that there was no visible scar tissue. Additional tests with other animal models showed the same thing: Wherever the adhesive-coated devices were implanted, fibrosis did not occur, for up to three months.

“This work really has identified a very general strategy, not only for one animal model, one organ, or one application,” Wu says. “Across all of these animal models, we have consistent, reproducible results without any observable fibrotic capsule.”

Using bulk RNA sequencing and fluorescent imaging, the researchers analyzed the animals’ immune response and found that when devices with adhesive coatings were first implanted, immune cells such as neutrophils began to infiltrate the area. However, the attacks quickly quenched out before any scar tissue could form.

“For the adhered devices, there is an acute inflammatory response because it is a foreign material,” Yuk says. “However, very quickly that inflammatory response decayed, and then from that point you do not have this fibrosis formation.”

One application for this adhesive could be coatings for epicardial pacemakers — devices that are placed on the heart to help control the heart rate. The wires that contact the heart often become fibrotic, but the MIT team found that when they implanted adhesive-coated wires in rats, they remained functional for at least three months, with no scar tissue formation.

“The formation of fibrotic tissue at the interface between implanted medical devices and the target tissue is a longstanding problem that routinely causes failure of the device. The demonstration that robust adhesion between the device and the tissue obviates fibrotic tissue formation is an important observation that has many potential applications in the medical device space,” says David Mooney, a professor of bioengineering at Harvard University, who was not involved in the study.

Mechanical cues

The researchers also tested a hydrogel adhesive that includes chitosan, a naturally occurring polysaccharide, and found that this adhesive also eliminated fibrosis in animal studies. However, two commercially available tissue adhesives that they tested did not show this antifibrotic effect because the commercially available adhesives eventually detached from the tissue and allowed the immune system to attack.

In another experiment, the researchers coated implants in hydrogel adhesives but then soaked them in a solution that removed the polymers’ adhesive properties, while keeping their overall chemical structure the same. After being implanted in the body, where they were held in place by sutures, fibrotic scarring occurred. This suggests that there is something about the mechanical interaction between the adhesive and the tissue that prevents the immune system from attacking, the researchers say.

“Previous research in immunology has been focused on chemistry and biochemistry, but mechanics and physics may play equivalent roles, and we should pay attention to those mechanical and physical cues in immunological responses,” says Zhao, who now plans to further investigate how those mechanical cues affect the immune system.

Yuk, Zhao, and others have started a company called SanaHeal, which is now working on further developing tissue adhesives for medical applications.

“As a team, we are interested in reporting this to the community and sparking speculation and imagination as to where this can go,” Yuk says. “There are so many scenarios in which people want to interface with foreign or manmade material in the body, like implantable devices, drug depots, or cell depots.”

The research was funded by the National Institutes of Health and the National Science Foundation.
