Welcome to the world of a French-loving, American couple

How to Write a Stellar Mémoire (French Master’s Thesis)

Pursuing graduate studies in France entails mastering all sorts of assignments, but perhaps none as daunting as the notorious mémoire , or master’s thesis. Writing and defending a master’s thesis is the cornerstone of many, though not all, French graduate degrees, making it a rite of passage for degree-seeking students in France. As part of my French master’s degree in Droit Public parcours Intégration Européenne et Gouvernance Globale , I was required to take on the infamous mémoire alongside my regular coursework during the final year of my studies.

Since I’m an international student at the Université de Reims Champagne-Ardenne , I had to contend not only with the base-level difficulties of putting together a master’s thesis, but also with the reality of writing fully in my second language and following the unforgiving methodology and writing norms of French law school to a tee. Needless to say, my year-long research project entailed late nights spent reading, countless trips to the library, typing until my fingers were sore, and shedding a few more tears than I’d like to admit!

My master’s thesis experience wasn’t all bad, of course. I genuinely enjoyed learning everything I could about my topic, discussing my progress with my classmates, refining my French-language skills , and presenting a piece of work that reflected my academic rigor. To my delight, at the end of my defense, the jury awarded me an 18/20 for my mémoire , entitled Associer les inégalités sociales et le changement climatique : Une étude comparative des contextes et approches aux États-Unis et dans l’Union européenne . The jury highlighted the following assets of my work:

• Qualité de recherche (Research quality)
• Qualité rédactionnelle (Writing quality)
• Qualité de français (French-language quality)
• Problématique innovante (Innovative research question)
• Posture épistémologique intéressant (Interesting epistemological posture)
• Bon cadrage théorique (Good theoretical framework)
• Limitations justifiées (Justified limitations)
• Structure impeccable (Impeccable structure)

Managing to receive the highest honors on my mémoire as an American studying law in France was no easy feat. Throughout the lengthy process of crafting my master’s thesis and defense, I discovered what worked well for me and what held me back – that’s why, in this post, I’m sharing my expert tips to help you write an outstanding French master’s thesis.

Honor Your Interests

Completing a mémoire takes months of daily research, reading, and writing, so you can imagine how painful the whole operation can become if your topic doesn’t inspire you! For a certain amount of time, your master’s thesis content will likely be all you can think about as you attempt to find and consume every piece of relevant literature ever written about it. To avoid misery and increase your motivation, you need to reflect upon the subjects within your degree field that excite you, the themes you’d be delighted to learn more about, and the concepts you truly want to call yourself an expert in come the day of your defense.

• My research topic combined my enthusiasm for the themes of public policy and governance, social justice issues, environmental protection, the United States, and the European Union.

Favor Innovation

The goal of producing a master’s thesis is not to reiterate the conclusions that other researchers have already drawn, but to pull from existing knowledge in order to demonstrate something new. To elevate your mémoire and impress your jury, innovation is indispensable. Creating a research question that hasn’t already been exhaustively answered will also prevent you from simply regurgitating what you read and will allow you to write a master’s thesis that relies on the important work of those before you, but is, ultimately, entirely your own.

• In my case, the concept of linking social inequality and climate change is relatively new on the whole. Moreover, my comparison of the United States’ and the European Union’s approaches for dealing with this phenomenon is something that hadn’t been done before.

Survey Your Sources

Because a finished mémoire is the culmination of in-depth research and analysis, you’ll need to choose a topic that you can thoroughly explore. For example, if your desired subject is too cutting-edge, you may struggle to find sufficient existing material upon which to build your master’s thesis. If essential documents that you need to read are confidential, located far away, or otherwise inaccessible, you won’t be able to use them for your work. It is therefore essential to consider whether adequate sources are available before you set your heart on a specific theme.

• When finalizing my topic, I ensured that the sources I would need to study were either located online, at my university , or in libraries near me.

Create a Timeline

You know that you should start working on your master’s thesis at the beginning of the school year , and that you need to have it finished by the end, but what happens between those two events is much less clear! With the help of a trusted professor or independently, you should make a realistic schedule with self-imposed deadlines to help you conceptualize the amount of work that needs to be done by each date. Your timeline should include targets for things like finalizing your research question, gathering sources for your bibliography, writing the various sections of the manuscript, submitting your mémoire for review, and preparing for your defense.

• Using a holistic timeline helped me to know when I was on track, when I could take breaks, and when I needed to speed things along. It also enabled me to beat procrastination, as delaying tasks for too long would have thrown me completely off schedule.

Chat About Your Research

While a master’s thesis is definitely an individual project, you shouldn’t keep your thoughts and questions to yourself! Your professors, classmates, friends, and family are all valuable resources as you go through the mémoire process. Speaking with your professors (who have already successfully completed challenging research projects) and with your classmates (who are currently working on their own mémoires ) about things like methodological difficulties and research hardships can lead to helpful problem solving and sincere moral support. Moreover, explaining your research to friends and family (who are likely unfamiliar with your subject) will help you gauge how well you understand it yourself and how clearly you’re able to express your ideas.

• I personally checked in regularly with my classmates who always offered useful words of advice and encouragement. I also talked with my significant other, Jalen , frequently to get his feedback on my work.

Choose the Right Advisor

Selecting a directeur·rice de mémoire , or master’s thesis advisor, isn’t a decision to make lightly. To find the perfect fit, you need to be familiar with your potential advisors and know your own preferences very well. For example, asking a professor whose specialty has nothing to do with your research question is likely to be as uninteresting for them as it is unhelpful to you. Furthermore, if you’re a student who likes frequent and detailed feedback, choosing a professor with a tightly-packed schedule might not be the best idea. Take the time to weigh your options carefully before asking a professor to become your advisor.

• I made sure to pick an advisor who was familiar with the broad strokes of my topic and had a hands-off attitude so that I could work autonomously and at my own pace.

Write Meticulously

The quality of the content of your master’s thesis is crucial, but so is the quality of your writing. The most brilliant of ideas will still fall flat if your text is riddled with grammatical errors and spelling mistakes. Attempting to avoid all language blunders is especially vital when you’re writing in your second language – and even more so in a country like France where such mistakes are not looked upon kindly. If your manuscript is hard to understand, readers won’t be able to appreciate your analysis. Additionally, it’s tough for readers to take a piece of work seriously if they’re constantly distracted by careless errors. Try to compose every sentence with care in order to avoid these pitfalls.

• When writing my mémoire , I never hesitated to look up a word, phrase, or grammar rule when I was even the tiniest bit uncertain. I also double-checked for errors that I commonly make, like accidentally including a serial comma when I’m writing in French.

Perfect Your Formatting

You shouldn’t organize your master’s thesis like you would a novel, an essay, or a report. Depending on your field of study and your degree program’s requirements, you’ll likely have specific norms to apply and rules to follow for structuring your mémoire . Your acknowledgements, dedication, abstract, abbreviations, table of contents, references, and appendices can’t be placed just anywhere! You should also ensure that your work is pleasing to the eye, with an appropriate cover page, sensible headings, proper font sizes and line spacing, logical page breaks, and accurate citations. These details are what make the difference between a good master’s thesis and a great one.

• In French law school, for example, writing to a detailed, hierarchical outline, known as a plan , is often an absolute must. As such, the final version of my master’s thesis manuscript consists of an introduction, two chapters with three sections and eight sub-sections each, and a conclusion.

Prepare Your Defense

When you’re finally done writing your master’s thesis, it can be tempting to put it completely out of your mind. But once you conquer this first step, you still have one more challenge to tackle: your soutenance , or master’s thesis defense. To pass your defense, you need to do more than just prepare to present your research and findings to the jury. A quality presentation will also include explaining the reason you chose your topic, the sources you used, the problems you faced , the limitations of your work, any updates on your subject since you finished writing, and future research possibilities. Don’t forget to reread your mémoire with a critical eye to anticipate the jury’s critiques in advance. Going the extra mile to prepare your defense to the best of your ability is a recipe for triumph.

• I prepared for my defense one week in advance, and it consisted of a 20-minute presentation, a 25-minute question and answer session, and a 10-minute jury deliberation.

Take Your Work Seriously

It’s no secret that some degree programs are more rigorous than others, just as it’s true that some students take their studies more seriously than others. However, if you decide that writing a solid master’s thesis demonstrating your academic talents and integrity isn’t worth your time because you know that your program will accept work of lower calibre, you’ve effectively proven your degree to be a second-rate credential and yourself to be a substandard student. Would you rather throw together a mediocre mémoire that you’ll stuff away the moment it’s over, or compose a meaningful piece of work representing the best of your capacities that you’ll be excited to share with others for years to come? Taking your work seriously won’t steer you wrong, especially when it comes to an assignment as noteworthy as a master’s thesis.

• I know that my decision to do my absolute best played a large role in the jury’s attribution of my final grade, and I’m proud of myself for having done so.

Everyone’s master’s thesis journey is unique, but implementing these tips will put you on a path to success. Is writing a French mémoire in your future? Have you ever carried out a significant research project? Do you want to know more about my experience? Let me know in a comment!

The Dissertation: Writing in French

Dissertation is a very specific way to write what we call a “paper.” In France, this style is used in academics and the professional world alike.

The Necessities

• Personal reaction: Be sincere, though not informal.
• Use examples to affirm your point. Using examples limits verbiage, generalities, and banalities.
• Be clear and coherent : A good paper should resemble a mathematical proof more than a lyrical flood of words. Be understandable and operate by the Law of Occam’s Razor (the simplest explanation tends to be the best one.)
• Outline : Getting your ideas on paper is harder than coming up with them in the first place. In order to convey your ideas effectively to the reader, outline!

The Schema of a Dissertation

In order to write a dissertation, you need a problem or problématique. Situate that problem within your topic or subject. Do not begin to write without these ideas in mind.

Introduction

• The introduction must rapidly situate and introduce the problem. Cite briefly.
• Give an idea of the movement of the paper, but do not announce each step of your work.
• Define key words.
• Attract the reader!  

The Body 

Separated into parts and paragraphs, where each part is a main point in the problem and each paragraph is one idea or one aspect of an idea.

• Thesis – often the predominant point of view (the most common analysis)
• Synthesis: Establish some nuanced truth in between the two arguments or overcome of the initial contradiction by bringing in additional information.
• “Problem-Cause-Solution” Plan: Introduce and define a problem, pinpoint its causes, and propose a solution.
• Separate your argument into parts (in this case, two: benefits and pleasures)
• Order your arguments within each part
• first element of comparison (one point of view on an issue, for example)
• second element of comparison (an opposing point of view)
• Meditation on the facts presented in the first two parts
• Explanation of the formula (definition, par ex.)
• Commentary on the formula, for example, expansion of a definition, comments on appropriateness

The Conclusion

A conclusion must be written in the spirit of synthesis and with logical rigor. Coming to the end of an argument, a conclusion must be concise and strong. If desired, it can situate the results or thesis a more general sense.

The Dissertation Abstract: 101

How to write a clear & concise abstract (with examples).

By:   Madeline Fink (MSc) Reviewed By: Derek Jansen (MBA)   | June 2020

So, you’ve (finally) finished your thesis or dissertation or thesis. Now it’s time to write up your abstract (sometimes also called the executive summary). If you’re here, chances are you’re not quite sure what you need to cover in this section, or how to go about writing it. Fear not – we’ll explain it all in plain language , step by step , with clear examples .

Overview: The Dissertation/Thesis Abstract

• What exactly is a dissertation (or thesis) abstract
• What’s the purpose and function of the abstract
• Why is the abstract so important
• How to write a high-quality dissertation abstract
• Example/sample of a quality abstract
• Quick tips to write a high-quality dissertation abstract

What is an abstract?

Simply put, the abstract in a dissertation or thesis is a short (but well structured) summary that outlines the most important points of your research (i.e. the key takeaways). The abstract is usually 1 paragraph or about 300-500 words long (about one page), but but this can vary between universities.

A quick note regarding terminology – strictly speaking, an abstract and an executive summary are two different things when it comes to academic publications. Typically, an abstract only states what the research will be about, but doesn’t explore the findings – whereas an executive summary covers both . However, in the context of a dissertation or thesis, the abstract usually covers both, providing a summary of the full project.

In terms of content, a good dissertation abstract usually covers the following points:

• The purpose of the research (what’s it about and why’s that important)
• The methodology (how you carried out the research)
• The key research findings (what answers you found)
• The implications of these findings (what these answers mean)

We’ll explain each of these in more detail a little later in this post. Buckle up.

What’s the purpose of the abstract?

A dissertation abstract has two main functions:

The first purpose is to  inform potential readers  of the main idea of your research without them having to read your entire piece of work. Specifically, it needs to communicate what your research is about (what were you trying to find out) and what your findings were . When readers are deciding whether to read your dissertation or thesis, the abstract is the first part they’ll consider. 

The second purpose of the abstract is to  inform search engines and dissertation databases  as they index your dissertation or thesis. The keywords and phrases in your abstract (as well as your keyword list) will often be used by these search engines to categorize your work and make it accessible to users. 

Simply put, your abstract is your shopfront display window – it’s what passers-by (both human and digital) will look at before deciding to step inside. 

Why’s it so important?

The short answer – because most people don’t have time to read your full dissertation or thesis! Time is money, after all…

If you think back to when you undertook your literature review , you’ll quickly realise just how important abstracts are! Researchers reviewing the literature on any given topic face a mountain of reading, so they need to optimise their approach. A good dissertation abstract gives the reader a “TLDR” version of your work – it helps them decide whether to continue to read it in its entirety. So, your abstract, as your shopfront display window, needs to “sell” your research to time-poor readers.

You might be thinking, “but I don’t plan to publish my dissertation”. Even so, you still need to provide an impactful abstract for your markers. Your ability to concisely summarise your work is one of the things they’re assessing, so it’s vital to invest time and effort into crafting an enticing shop window.  

A good abstract also has an added purpose for grad students . As a freshly minted graduate, your dissertation or thesis is often your most significant professional accomplishment and highlights where your unique expertise lies. Potential employers who want to know about this expertise are likely to only read the abstract (as opposed to reading your entire document) – so it needs to be good!

Think about it this way – if your thesis or dissertation were a book, then the abstract would be the blurb on the back cover. For better or worse, readers will absolutely judge your book by its cover .

How to write your abstract

As we touched on earlier, your abstract should cover four important aspects of your research: the purpose , methodology , findings , and implications . Therefore, the structure of your dissertation or thesis abstract needs to reflect these four essentials, in the same order.  Let’s take a closer look at each of them, step by step:

Step 1: Describe the purpose and value of your research

Here you need to concisely explain the purpose and value of your research. In other words, you need to explain what your research set out to discover and why that’s important. When stating the purpose of research, you need to clearly discuss the following:

• What were your research aims and research questions ?
• Why were these aims and questions important?

It’s essential to make this section extremely clear, concise and convincing . As the opening section, this is where you’ll “hook” your reader (marker) in and get them interested in your project. If you don’t put in the effort here, you’ll likely lose their interest.

Step 2: Briefly outline your study’s methodology

In this part of your abstract, you need to very briefly explain how you went about answering your research questions . In other words, what research design and methodology you adopted in your research. Some important questions to address here include:

• Did you take a qualitative or quantitative approach ?
• Who/what did your sample consist of?
• How did you collect your data?
• How did you analyse your data?

Simply put, this section needs to address the “ how ” of your research. It doesn’t need to be lengthy (this is just a summary, after all), but it should clearly address the four questions above.

Need a helping hand?

Step 3: Present your key findings

Next, you need to briefly highlight the key findings . Your research likely produced a wealth of data and findings, so there may be a temptation to ramble here. However, this section is just about the key findings – in other words, the answers to the original questions that you set out to address.

Again, brevity and clarity are important here. You need to concisely present the most important findings for your reader.

Step 4: Describe the implications of your research

Have you ever found yourself reading through a large report, struggling to figure out what all the findings mean in terms of the bigger picture? Well, that’s the purpose of the implications section – to highlight the “so what?” of your research. 

In this part of your abstract, you should address the following questions:

• What is the impact of your research findings on the industry /field investigated? In other words, what’s the impact on the “real world”. 
• What is the impact of your findings on the existing body of knowledge ? For example, do they support the existing research?
• What might your findings mean for future research conducted on your topic?

If you include these four essential ingredients in your dissertation abstract, you’ll be on headed in a good direction.

Example: Dissertation/thesis abstract

Here is an example of an abstract from a master’s thesis, with the purpose , methods , findings , and implications colour coded.

The U.S. citizenship application process is a legal and symbolic journey shaped by many cultural processes. This research project aims to bring to light the experiences of immigrants and citizenship applicants living in Dallas, Texas, to promote a better understanding of Dallas’ increasingly diverse population. Additionally, the purpose of this project is to provide insights to a specific client, the office of Dallas Welcoming Communities and Immigrant Affairs, about Dallas’ lawful permanent residents who are eligible for citizenship and their reasons for pursuing citizenship status . The data for this project was collected through observation at various citizenship workshops and community events, as well as through semi-structured interviews with 14 U.S. citizenship applicants . Reasons for applying for U.S. citizenship discussed in this project include a desire for membership in U.S. society, access to better educational and economic opportunities, improved ease of travel and the desire to vote. Barriers to the citizenship process discussed in this project include the amount of time one must dedicate to the application, lack of clear knowledge about the process and the financial cost of the application. Other themes include the effects of capital on applicant’s experience with the citizenship process, symbolic meanings of citizenship, transnationalism and ideas of deserving and undeserving surrounding the issues of residency and U.S. citizenship. These findings indicate the need for educational resources and mentorship for Dallas-area residents applying for U.S. citizenship, as well as a need for local government programs that foster a sense of community among citizenship applicants and their neighbours.

Practical tips for writing your abstract

When crafting the abstract for your dissertation or thesis, the most powerful technique you can use is to try and put yourself in the shoes of a potential reader. Assume the reader is not an expert in the field, but is interested in the research area. In other words, write for the intelligent layman, not for the seasoned topic expert. 

Start by trying to answer the question “why should I read this dissertation?”

Remember the WWHS.

Make sure you include the  what , why ,  how , and  so what  of your research in your abstract:

• What you studied (who and where are included in this part)
• Why the topic was important
• How you designed your study (i.e. your research methodology)
• So what were the big findings and implications of your research

Keep it simple.

Use terminology appropriate to your field of study, but don’t overload your abstract with big words and jargon that cloud the meaning and make your writing difficult to digest. A good abstract should appeal to all levels of potential readers and should be a (relatively) easy read. Remember, you need to write for the intelligent layman.

Be specific.

When writing your abstract, clearly outline your most important findings and insights and don’t worry about “giving away” too much about your research – there’s no need to withhold information. This is the one way your abstract is not like a blurb on the back of a book – the reader should be able to clearly understand the key takeaways of your thesis or dissertation after reading the abstract. Of course, if they then want more detail, they need to step into the restaurant and try out the menu.

Psst… there’s more (for free)

• How to Write an Abstract for a Dissertation or Thesis
• Doing a PhD

What is a Thesis or Dissertation Abstract?

The Cambridge English Dictionary defines an abstract in academic writing as being “ a few sentences that give the main ideas in an article or a scientific paper ” and the Collins English Dictionary says “ an abstract of an article, document, or speech is a short piece of writing that gives the main points of it ”.

Whether you’re writing up your Master’s dissertation or PhD thesis, the abstract will be a key element of this document that you’ll want to make sure you give proper attention to.

What is the Purpose of an Abstract?

The aim of a thesis abstract is to give the reader a broad overview of what your research project was about and what you found that was novel, before he or she decides to read the entire thesis. The reality here though is that very few people will read the entire thesis, and not because they’re necessarily disinterested but because practically it’s too large a document for most people to have the time to read. The exception to this is your PhD examiner, however know that even they may not read the entire length of the document.

Some people may still skip to and read specific sections throughout your thesis such as the methodology, but the fact is that the abstract will be all that most read and will therefore be the section they base their opinions about your research on. In short, make sure you write a good, well-structured abstract.

How Long Should an Abstract Be?

If you’re a PhD student, having written your 100,000-word thesis, the abstract will be the 300 word summary included at the start of the thesis that succinctly explains the motivation for your study (i.e. why this research was needed), the main work you did (i.e. the focus of each chapter), what you found (the results) and concluding with how your research study contributed to new knowledge within your field.

Woodrow Wilson, the 28th President of the United States of America, once famously said:

The point here is that it’s easier to talk open-endedly about a subject that you know a lot about than it is to condense the key points into a 10-minute speech; the same applies for an abstract. Three hundred words is not a lot of words which makes it even more difficult to condense three (or more) years of research into a coherent, interesting story.

What Makes a Good PhD Thesis Abstract?

Whilst the abstract is one of the first sections in your PhD thesis, practically it’s probably the last aspect that you’ll ending up writing before sending the document to print. The reason being that you can’t write a summary about what you did, what you found and what it means until you’ve done the work.

A good abstract is one that can clearly explain to the reader in 300 words:

• What your research field actually is,
• What the gap in knowledge was in your field,
• The overarching aim and objectives of your PhD in response to these gaps,
• What methods you employed to achieve these,
• You key results and findings,
• How your work has added to further knowledge in your field of study.

Another way to think of this structure is:

• Introduction,
• Aims and objectives,
• Discussion,
• Conclusion.

Following this ‘formulaic’ approach to writing the abstract should hopefully make it a little easier to write but you can already see here that there’s a lot of information to convey in a very limited number of words.

How Do You Write a Good PhD Thesis Abstract?

The biggest challenge you’ll have is getting all the 6 points mentioned above across in your abstract within the limit of 300 words . Your particular university may give some leeway in going a few words over this but it’s good practice to keep within this; the art of succinctly getting your information across is an important skill for a researcher to have and one that you’ll be called on to use regularly as you write papers for peer review.

Keep It Concise

Every word in the abstract is important so make sure you focus on only the key elements of your research and the main outcomes and significance of your project that you want the reader to know about. You may have come across incidental findings during your research which could be interesting to discuss but this should not happen in the abstract as you simply don’t have enough words. Furthermore, make sure everything you talk about in your thesis is actually described in the main thesis.

Make a Unique Point Each Sentence

Keep the sentences short and to the point. Each sentence should give the reader new, useful information about your research so there’s no need to write out your project title again. Give yourself one or two sentences to introduce your subject area and set the context for your project. Then another sentence or two to explain the gap in the knowledge; there’s no need or expectation for you to include references in the abstract.

Explain Your Research

Some people prefer to write their overarching aim whilst others set out their research questions as they correspond to the structure of their thesis chapters; the approach you use is up to you, as long as the reader can understand what your dissertation or thesis had set out to achieve. Knowing this will help the reader better understand if your results help to answer the research questions or if further work is needed.

Keep It Factual

Keep the content of the abstract factual; that is to say that you should avoid bringing too much or any opinion into it, which inevitably can make the writing seem vague in the points you’re trying to get across and even lacking in structure.

Write, Edit and Then Rewrite

Spend suitable time editing your text, and if necessary, completely re-writing it. Show the abstract to others and ask them to explain what they understand about your research – are they able to explain back to you each of the 6 structure points, including why your project was needed, the research questions and results, and the impact it had on your research field? It’s important that you’re able to convey what new knowledge you contributed to your field but be mindful when writing your abstract that you don’t inadvertently overstate the conclusions, impact and significance of your work.

Thesis and Dissertation Abstract Examples

Perhaps the best way to understand how to write a thesis abstract is to look at examples of what makes a good and bad abstract.

Example of A Bad Abstract

Let’s start with an example of a bad thesis abstract:

In this project on “The Analysis of the Structural Integrity of 3D Printed Polymers for use in Aircraft”, my research looked at how 3D printing of materials can help the aviation industry in the manufacture of planes. Plane parts can be made at a lower cost using 3D printing and made lighter than traditional components. This project investigated the structural integrity of EBM manufactured components, which could revolutionise the aviation industry.

What Makes This a Bad Abstract

Hopefully you’ll have spotted some of the reasons this would be considered a poor abstract, not least because the author used up valuable words by repeating the lengthy title of the project in the abstract.

Working through our checklist of the 6 key points you want to convey to the reader:

• There has been an attempt to introduce the research area , albeit half-way through the abstract but it’s not clear if this is a materials science project about 3D printing or is it about aircraft design.
• There’s no explanation about where the gap in the knowledge is that this project attempted to address.
• We can see that this project was focussed on the topic of structural integrity of materials in aircraft but the actual research aims or objectives haven’t been defined.
• There’s no mention at all of what the author actually did to investigate structural integrity. For example was this an experimental study involving real aircraft, or something in the lab, computer simulations etc.
• The author also doesn’t tell us a single result of his research, let alone the key findings !
• There’s a bold claim in the last sentence of the abstract that this project could revolutionise the aviation industry, and this may well be the case, but based on the abstract alone there is no evidence to support this as it’s not even clear what the author did .

This is an extreme example but is a good way to illustrate just how unhelpful a poorly written abstract can be. At only 71 words long, it definitely hasn’t maximised the amount of information that could be presented and the what they have presented has lacked clarity and structure.

A final point to note is the use of the EBM acronym, which stands for Electron Beam Melting in the context of 3D printing; this is a niche acronym for the author to assume that the reader would know the meaning of. It’s best to avoid acronyms in your abstract all together even if it’s something that you might expect most people to know about, unless you specifically define the meaning first.

Example of A Good Abstract

Having seen an example of a bad thesis abstract, now lets look at an example of a good PhD thesis abstract written about the same (fictional) project:

Additive manufacturing (AM) of titanium alloys has the potential to enable cheaper and lighter components to be produced with customised designs for use in aircraft engines. Whilst the proof-of-concept of these have been promising, the structural integrity of AM engine parts in response to full thrust and temperature variations is not clear.

The primary aim of this project was to determine the fracture modes and mechanisms of AM components designed for use in Boeing 747 engines. To achieve this an explicit finite element (FE) model was developed to simulate the environment and parameters that the engine is exposed to during flight. The FE model was validated using experimental data replicating the environmental parameters in a laboratory setting using ten AM engine components provided by the industry sponsor. The validated FE model was then used to investigate the extent of crack initiation and propagation as the environment parameters were adjusted.

This project was the first to investigate fracture patterns in AM titanium components used in aircraft engines; the key finding was that the presence of cavities within the structures due to errors in the printing process, significantly increased the risk of fracture. Secondly, the simulations showed that cracks formed within AM parts were more likely to worsen and lead to component failure at subzero temperatures when compared to conventionally manufactured parts. This has demonstrated an important safety concern which needs to be addressed before AM parts can be used in commercial aircraft.

What Makes This a Good Abstract

Having read this ‘good abstract’ you should have a much better understand about what the subject area is about, where the gap in the knowledge was, the aim of the project, the methods that were used, key results and finally the significance of these results. To break these points down further, from this good abstract we now know that:

• The research area is around additive manufacturing (i.e. 3D printing) of materials for use in aircraft.
• The gap in knowledge was how these materials will behave structural when used in aircraft engines.
• The aim was specifically to investigate how the components can fracture.
• The methods used to investigate this were a combination of computational and lab based experimental modelling.
• The key findings were the increased risk of fracture of these components due to the way they are manufactured.
• The significance of these findings were that it showed a potential risk of component failure that could comprise the safety of passengers and crew on the aircraft.

The abstract text has a much clearer flow through these different points in how it’s written and has made much better use of the available word count. Acronyms have even been used twice in this good abstract but they were clearly defined the first time they were introduced in the text so that there was no confusion about their meaning.

The abstract you write for your dissertation or thesis should succinctly explain to the reader why the work of your research was needed, what you did, what you found and what it means. Most people that come across your thesis, including any future employers, are likely to read only your abstract. Even just for this reason alone, it’s so important that you write the best abstract you can; this will not only convey your research effectively but also put you in the best light possible as a researcher.

A new French teaching program, “French for Spanish Speakers” (FSS) is spreading throughout Southern California whose aim is to bridge Spanish and English to facilitate learning French. FSS speculates that Spanish-English speakers have a greater advantage in learning French than monolingual English speakers (MES). This thesis is the first to empirically examine these speculations. The first section contrasts four linguistically different groups’ French grammar and French written fluency, accuracy, and complexity. The second section attempts to evaluate the FSS program. This study found a statistically significant difference in which Spanish-English speakers produced more fluent and complex compositions than MES. In addition, the findings of this study predict that Spanish-English speakers will ultimately internalize and retain French longer than MES. However, there seems to be no statistical significance in terms of written performance between Spanish-English speakers enrolled in FSS and those enrolled in regular French courses.

How to Write an Abstract | Steps & Examples

Published on February 28, 2019 by Shona McCombes . Revised on July 18, 2023 by Eoghan Ryan.

An abstract is a short summary of a longer work (such as a thesis ,  dissertation or research paper ). The abstract concisely reports the aims and outcomes of your research, so that readers know exactly what your paper is about.

Although the structure may vary slightly depending on your discipline, your abstract should describe the purpose of your work, the methods you’ve used, and the conclusions you’ve drawn.

One common way to structure your abstract is to use the IMRaD structure. This stands for:

• Introduction

Abstracts are usually around 100–300 words, but there’s often a strict word limit, so make sure to check the relevant requirements.

In a dissertation or thesis , include the abstract on a separate page, after the title page and acknowledgements but before the table of contents .

Hover over the different parts of the abstract to see how it is constructed.

This paper examines the role of silent movies as a mode of shared experience in the US during the early twentieth century. At this time, high immigration rates resulted in a significant percentage of non-English-speaking citizens. These immigrants faced numerous economic and social obstacles, including exclusion from public entertainment and modes of discourse (newspapers, theater, radio).

Incorporating evidence from reviews, personal correspondence, and diaries, this study demonstrates that silent films were an affordable and inclusive source of entertainment. It argues for the accessible economic and representational nature of early cinema. These concerns are particularly evident in the low price of admission and in the democratic nature of the actors’ exaggerated gestures, which allowed the plots and action to be easily grasped by a diverse audience despite language barriers.

Keywords: silent movies, immigration, public discourse, entertainment, early cinema, language barriers.

Here's why students love Scribbr's proofreading services

Discover proofreading & editing

You will almost always have to include an abstract when:

• Completing a thesis or dissertation
• Submitting a research paper to an academic journal
• Writing a book or research proposal
• Applying for research grants

It’s easiest to write your abstract last, right before the proofreading stage, because it’s a summary of the work you’ve already done. Your abstract should:

• Be a self-contained text, not an excerpt from your paper
• Be fully understandable on its own
• Reflect the structure of your larger work

Start by clearly defining the purpose of your research. What practical or theoretical problem does the research respond to, or what research question did you aim to answer?

You can include some brief context on the social or academic relevance of your dissertation topic , but don’t go into detailed background information. If your abstract uses specialized terms that would be unfamiliar to the average academic reader or that have various different meanings, give a concise definition.

After identifying the problem, state the objective of your research. Use verbs like “investigate,” “test,” “analyze,” or “evaluate” to describe exactly what you set out to do.

This part of the abstract can be written in the present or past simple tense  but should never refer to the future, as the research is already complete.

• This study will investigate the relationship between coffee consumption and productivity.
• This study investigates the relationship between coffee consumption and productivity.

Next, indicate the research methods that you used to answer your question. This part should be a straightforward description of what you did in one or two sentences. It is usually written in the past simple tense, as it refers to completed actions.

• Structured interviews will be conducted with 25 participants.
• Structured interviews were conducted with 25 participants.

Don’t evaluate validity or obstacles here — the goal is not to give an account of the methodology’s strengths and weaknesses, but to give the reader a quick insight into the overall approach and procedures you used.

Receive feedback on language, structure, and formatting

Professional editors proofread and edit your paper by focusing on:

• Academic style
• Vague sentences
• Style consistency

See an example

Next, summarize the main research results . This part of the abstract can be in the present or past simple tense.

• Our analysis has shown a strong correlation between coffee consumption and productivity.
• Our analysis shows a strong correlation between coffee consumption and productivity.
• Our analysis showed a strong correlation between coffee consumption and productivity.

Depending on how long and complex your research is, you may not be able to include all results here. Try to highlight only the most important findings that will allow the reader to understand your conclusions.

Finally, you should discuss the main conclusions of your research : what is your answer to the problem or question? The reader should finish with a clear understanding of the central point that your research has proved or argued. Conclusions are usually written in the present simple tense.

• We concluded that coffee consumption increases productivity.
• We conclude that coffee consumption increases productivity.

If there are important limitations to your research (for example, related to your sample size or methods), you should mention them briefly in the abstract. This allows the reader to accurately assess the credibility and generalizability of your research.

If your aim was to solve a practical problem, your discussion might include recommendations for implementation. If relevant, you can briefly make suggestions for further research.

If your paper will be published, you might have to add a list of keywords at the end of the abstract. These keywords should reference the most important elements of the research to help potential readers find your paper during their own literature searches.

Be aware that some publication manuals, such as APA Style , have specific formatting requirements for these keywords.

It can be a real challenge to condense your whole work into just a couple of hundred words, but the abstract will be the first (and sometimes only) part that people read, so it’s important to get it right. These strategies can help you get started.

Read other abstracts

The best way to learn the conventions of writing an abstract in your discipline is to read other people’s. You probably already read lots of journal article abstracts while conducting your literature review —try using them as a framework for structure and style.

You can also find lots of dissertation abstract examples in thesis and dissertation databases .

Reverse outline

Not all abstracts will contain precisely the same elements. For longer works, you can write your abstract through a process of reverse outlining.

For each chapter or section, list keywords and draft one to two sentences that summarize the central point or argument. This will give you a framework of your abstract’s structure. Next, revise the sentences to make connections and show how the argument develops.

Write clearly and concisely

A good abstract is short but impactful, so make sure every word counts. Each sentence should clearly communicate one main point.

To keep your abstract or summary short and clear:

• Avoid passive sentences: Passive constructions are often unnecessarily long. You can easily make them shorter and clearer by using the active voice.
• Avoid long sentences: Substitute longer expressions for concise expressions or single words (e.g., “In order to” for “To”).
• Avoid obscure jargon: The abstract should be understandable to readers who are not familiar with your topic.
• Avoid repetition and filler words: Replace nouns with pronouns when possible and eliminate unnecessary words.
• Avoid detailed descriptions: An abstract is not expected to provide detailed definitions, background information, or discussions of other scholars’ work. Instead, include this information in the body of your thesis or paper.

If you’re struggling to edit down to the required length, you can get help from expert editors with Scribbr’s professional proofreading services or use the paraphrasing tool .

Check your formatting

If you are writing a thesis or dissertation or submitting to a journal, there are often specific formatting requirements for the abstract—make sure to check the guidelines and format your work correctly. For APA research papers you can follow the APA abstract format .

Checklist: Abstract

The word count is within the required length, or a maximum of one page.

The abstract appears after the title page and acknowledgements and before the table of contents .

I have clearly stated my research problem and objectives.

I have briefly described my methodology .

I have summarized the most important results .

I have stated my main conclusions .

I have mentioned any important limitations and recommendations.

The abstract can be understood by someone without prior knowledge of the topic.

An abstract is a concise summary of an academic text (such as a journal article or dissertation ). It serves two main purposes:

• To help potential readers determine the relevance of your paper for their own research.
• To communicate your key findings to those who don’t have time to read the whole paper.

Abstracts are often indexed along with keywords on academic databases, so they make your work more easily findable. Since the abstract is the first thing any reader sees, it’s important that it clearly and accurately summarizes the contents of your paper.

An abstract for a thesis or dissertation is usually around 200–300 words. There’s often a strict word limit, so make sure to check your university’s requirements.

The abstract is the very last thing you write. You should only write it after your research is complete, so that you can accurately summarize the entirety of your thesis , dissertation or research paper .

Avoid citing sources in your abstract . There are two reasons for this:

• The abstract should focus on your original research, not on the work of others.
• The abstract should be self-contained and fully understandable without reference to other sources.

There are some circumstances where you might need to mention other sources in an abstract: for example, if your research responds directly to another study or focuses on the work of a single theorist. In general, though, don’t include citations unless absolutely necessary.

The abstract appears on its own page in the thesis or dissertation , after the title page and acknowledgements but before the table of contents .

A current challenge in silicon chemistry is to perform liquid-phase synthesis of silicon nanoparticles, which would permit the use of colloidal synthesis techniques to control size and shape. Herein we show how silicon nanoparticles were synthesized at ambient temperature and pressure in organic solvents through a redox reaction. Specifically, a hexacoordinated silicon complex, bis( N , N ′-diisopropylbutylamidinato)dichlorosilane, was reduced by a silicon Zintl phase, sodium silicide (Na 4 Si 4 ). The resulting silicon nanoparticles were crystalline with sizes tuned from a median particle diameter of 15 nm to 45 nm depending on the solvent. Photoluminescence measurements performed on colloidal suspensions of the 45 nm diameter silicon nanoparticles indicated a blue emission signal, attributed to the partial oxidation of the Si nanocrystals or to the presence of nitrogen impurities.
