Objectives: There is considerable actual and potential waste in research. Evidence-based research ensures worthwhile and valuable research. The aim of this series, which this article introduces, is to describe the evidence-based research approach.

Study design and setting: In this first article of a three-article series, we introduce the evidence-based research approach. Evidence-based research is the use of prior research in a systematic and transparent way to inform a new study so that it is answering questions that matter in a valid, efficient, and accessible manner.

Results: We describe evidence-based research and provide an overview of the approach of systematically and transparently using previous research before starting a new study to justify and design the new study (article #2 in series) and-on study completion-place its results in the context with what is already known (article #3 in series).

Conclusion: This series introduces evidence-based research as an approach to minimize unnecessary and irrelevant clinical health research that is unscientific, wasteful, and unethical.

Keywords: Clinical health research; Clinical trials; Evidence synthesis; Evidence-based research; Medical ethics; Research ethics; Systematic review.

11.1 The Purpose of Research Writing

Learning objectives.

  • Identify reasons to research writing projects.
  • Outline the steps of the research writing process.

Why was the Great Wall of China built? What have scientists learned about the possibility of life on Mars? What roles did women play in the American Revolution? How does the human brain create, store, and retrieve memories? Who invented the game of football, and how has it changed over the years?

You may know the answers to these questions off the top of your head. If you are like most people, however, you find answers to tough questions like these by searching the Internet, visiting the library, or asking others for information. To put it simply, you perform research.

Whether you are a scientist, an artist, a paralegal, or a parent, you probably perform research in your everyday life. When your boss, your instructor, or a family member asks you a question that you do not know the answer to, you locate relevant information, analyze your findings, and share your results. Locating, analyzing, and sharing information are key steps in the research process, and in this chapter, you will learn more about each step. By developing your research writing skills, you will prepare yourself to answer any question no matter how challenging.

Reasons for Research

When you perform research, you are essentially trying to solve a mystery—you want to know how something works or why something happened. In other words, you want to answer a question that you (and other people) have about the world. This is one of the most basic reasons for performing research.

But the research process does not end when you have solved your mystery. Imagine what would happen if a detective collected enough evidence to solve a criminal case, but she never shared her solution with the authorities. Presenting what you have learned from research can be just as important as performing the research. Research results can be presented in a variety of ways, but one of the most popular—and effective—presentation forms is the research paper . A research paper presents an original thesis, or purpose statement, about a topic and develops that thesis with information gathered from a variety of sources.

If you are curious about the possibility of life on Mars, for example, you might choose to research the topic. What will you do, though, when your research is complete? You will need a way to put your thoughts together in a logical, coherent manner. You may want to use the facts you have learned to create a narrative or to support an argument. And you may want to show the results of your research to your friends, your teachers, or even the editors of magazines and journals. Writing a research paper is an ideal way to organize thoughts, craft narratives or make arguments based on research, and share your newfound knowledge with the world.

Write a paragraph about a time when you used research in your everyday life. Did you look for the cheapest way to travel from Houston to Denver? Did you search for a way to remove gum from the bottom of your shoe? In your paragraph, explain what you wanted to research, how you performed the research, and what you learned as a result.

Research Writing and the Academic Paper

No matter what field of study you are interested in, you will most likely be asked to write a research paper during your academic career. For example, a student in an art history course might write a research paper about an artist’s work. Similarly, a student in a psychology course might write a research paper about current findings in childhood development.

Having to write a research paper may feel intimidating at first. After all, researching and writing a long paper requires a lot of time, effort, and organization. However, writing a research paper can also be a great opportunity to explore a topic that is particularly interesting to you. The research process allows you to gain expertise on a topic of your choice, and the writing process helps you remember what you have learned and understand it on a deeper level.

Research Writing at Work

Knowing how to write a good research paper is a valuable skill that will serve you well throughout your career. Whether you are developing a new product, studying the best way to perform a procedure, or learning about challenges and opportunities in your field of employment, you will use research techniques to guide your exploration. You may even need to create a written report of your findings. And because effective communication is essential to any company, employers seek to hire people who can write clearly and professionally.

Writing at Work

Take a few minutes to think about each of the following careers. How might each of these professionals use researching and research writing skills on the job?

  • Medical laboratory technician
  • Small business owner
  • Information technology professional
  • Freelance magazine writer

A medical laboratory technician or information technology professional might do research to learn about the latest technological developments in either of these fields. A small business owner might conduct research to learn about the latest trends in his or her industry. A freelance magazine writer may need to research a given topic to write an informed, up-to-date article.

Think about the job of your dreams. How might you use research writing skills to perform that job? Create a list of ways in which strong researching, organizing, writing, and critical thinking skills could help you succeed at your dream job. How might these skills help you obtain that job?

Steps of the Research Writing Process

How does a research paper grow from a folder of brainstormed notes to a polished final draft? No two projects are identical, but most projects follow a series of six basic steps.

These are the steps in the research writing process:

  • Choose a topic.
  • Plan and schedule time to research and write.
  • Conduct research.
  • Organize research and ideas.
  • Draft your paper.
  • Revise and edit your paper.

Each of these steps will be discussed in more detail later in this chapter. For now, though, we will take a brief look at what each step involves.

Step 1: Choosing a Topic

As you may recall from Chapter 8 “The Writing Process: How Do I Begin?” , to narrow the focus of your topic, you may try freewriting exercises, such as brainstorming. You may also need to ask a specific research question —a broad, open-ended question that will guide your research—as well as propose a possible answer, or a working thesis . You may use your research question and your working thesis to create a research proposal . In a research proposal, you present your main research question, any related subquestions you plan to explore, and your working thesis.

Step 2: Planning and Scheduling

Before you start researching your topic, take time to plan your researching and writing schedule. Research projects can take days, weeks, or even months to complete. Creating a schedule is a good way to ensure that you do not end up being overwhelmed by all the work you have to do as the deadline approaches.

During this step of the process, it is also a good idea to plan the resources and organizational tools you will use to keep yourself on track throughout the project. Flowcharts, calendars, and checklists can all help you stick to your schedule. See Chapter 11 “Writing from Research: What Will I Learn?” , Section 11.2 “Steps in Developing a Research Proposal” for an example of a research schedule.

Step 3: Conducting Research

When going about your research, you will likely use a variety of sources—anything from books and periodicals to video presentations and in-person interviews.

Your sources will include both primary sources and secondary sources . Primary sources provide firsthand information or raw data. For example, surveys, in-person interviews, and historical documents are primary sources. Secondary sources, such as biographies, literary reviews, or magazine articles, include some analysis or interpretation of the information presented. As you conduct research, you will take detailed, careful notes about your discoveries. You will also evaluate the reliability of each source you find.

Step 4: Organizing Research and the Writer’s Ideas

When your research is complete, you will organize your findings and decide which sources to cite in your paper. You will also have an opportunity to evaluate the evidence you have collected and determine whether it supports your thesis, or the focus of your paper. You may decide to adjust your thesis or conduct additional research to ensure that your thesis is well supported.

Remember, your working thesis is not set in stone. You can and should change your working thesis throughout the research writing process if the evidence you find does not support your original thesis. Never try to force evidence to fit your argument. For example, your working thesis is “Mars cannot support life-forms.” Yet, a week into researching your topic, you find an article in the New York Times detailing new findings of bacteria under the Martian surface. Instead of trying to argue that bacteria are not life forms, you might instead alter your thesis to “Mars cannot support complex life-forms.”

Step 5: Drafting Your Paper

Now you are ready to combine your research findings with your critical analysis of the results in a rough draft. You will incorporate source materials into your paper and discuss each source thoughtfully in relation to your thesis or purpose statement.

When you cite your reference sources, it is important to pay close attention to standard conventions for citing sources in order to avoid plagiarism , or the practice of using someone else’s words without acknowledging the source. Later in this chapter, you will learn how to incorporate sources in your paper and avoid some of the most common pitfalls of attributing information.

Step 6: Revising and Editing Your Paper

In the final step of the research writing process, you will revise and polish your paper. You might reorganize your paper’s structure or revise for unity and cohesion, ensuring that each element in your paper flows into the next logically and naturally. You will also make sure that your paper uses an appropriate and consistent tone.

Once you feel confident in the strength of your writing, you will edit your paper for proper spelling, grammar, punctuation, mechanics, and formatting. When you complete this final step, you will have transformed a simple idea or question into a thoroughly researched and well-written paper you can be proud of!

Review the steps of the research writing process. Then answer the questions on your own sheet of paper.

  • In which steps of the research writing process are you allowed to change your thesis?
  • In step 2, which types of information should you include in your project schedule?
  • What might happen if you eliminated step 4 from the research writing process?

Key Takeaways

  • People undertake research projects throughout their academic and professional careers in order to answer specific questions, share their findings with others, increase their understanding of challenging topics, and strengthen their researching, writing, and analytical skills.
  • The research writing process generally comprises six steps: choosing a topic, scheduling and planning time for research and writing, conducting research, organizing research and ideas, drafting a paper, and revising and editing the paper.

Every day people do research as they gather information to learn about something of interest. In the scientific world, however, research means something different than simply gathering information. Scientific research is characterized by its careful planning and observing, by its relentless efforts to understand and explain, and by its commitment to learn from everyone else seriously engaged in research. We call this kind of research scientific inquiry and define it as “formulating, testing, and revising hypotheses.” By “hypotheses” we do not mean the hypotheses you encounter in statistics courses. We mean predictions about what you expect to find and rationales for why you made these predictions. Throughout this and the remaining chapters we make clear that the process of scientific inquiry applies to all kinds of research studies and data, both qualitative and quantitative.

Part I. What Is Research?

Have you ever studied something carefully because you wanted to know more about it? Maybe you wanted to know more about your grandmother’s life when she was younger so you asked her to tell you stories from her childhood, or maybe you wanted to know more about a fertilizer you were about to use in your garden so you read the ingredients on the package and looked them up online. According to the dictionary definition, you were doing research.

Recall your high school assignments asking you to “research” a topic. The assignment likely included consulting a variety of sources that discussed the topic, perhaps including some “original” sources. Often, the teacher referred to your product as a “research paper.”

Were you conducting research when you interviewed your grandmother or wrote high school papers reviewing a particular topic? Our view is that you were engaged in part of the research process, but only a small part. In this book, we reserve the word “research” for what it means in the scientific world, that is, for scientific research or, more pointedly, for scientific inquiry .

Exercise 1.1

Before you read any further, write a definition of what you think scientific inquiry is. Keep it short—Two to three sentences. You will periodically update this definition as you read this chapter and the remainder of the book.

This book is about scientific inquiry—what it is and how to do it. For starters, scientific inquiry is a process, a particular way of finding out about something that involves a number of phases. Each phase of the process constitutes one aspect of scientific inquiry. You are doing scientific inquiry as you engage in each phase, but you have not done scientific inquiry until you complete the full process. Each phase is necessary but not sufficient.

In this chapter, we set the stage by defining scientific inquiry—describing what it is and what it is not—and by discussing what it is good for and why people do it. The remaining chapters build directly on the ideas presented in this chapter.

A first thing to know is that scientific inquiry is not all or nothing. “Scientificness” is a continuum. Inquiries can be more scientific or less scientific. What makes an inquiry more scientific? You might be surprised there is no universally agreed upon answer to this question. None of the descriptors we know of are sufficient by themselves to define scientific inquiry. But all of them give you a way of thinking about some aspects of the process of scientific inquiry. Each one gives you different insights.

An image of the book's description with the words like research, science, and inquiry and what the word research meant in the scientific world.

Exercise 1.2

As you read about each descriptor below, think about what would make an inquiry more or less scientific. If you think a descriptor is important, use it to revise your definition of scientific inquiry.

Creating an Image of Scientific Inquiry

We will present three descriptors of scientific inquiry. Each provides a different perspective and emphasizes a different aspect of scientific inquiry. We will draw on all three descriptors to compose our definition of scientific inquiry.

Descriptor 1. Experience Carefully Planned in Advance

Sir Ronald Fisher, often called the father of modern statistical design, once referred to research as “experience carefully planned in advance” (1935, p. 8). He said that humans are always learning from experience, from interacting with the world around them. Usually, this learning is haphazard rather than the result of a deliberate process carried out over an extended period of time. Research, Fisher said, was learning from experience, but experience carefully planned in advance.

This phrase can be fully appreciated by looking at each word. The fact that scientific inquiry is based on experience means that it is based on interacting with the world. These interactions could be thought of as the stuff of scientific inquiry. In addition, it is not just any experience that counts. The experience must be carefully planned . The interactions with the world must be conducted with an explicit, describable purpose, and steps must be taken to make the intended learning as likely as possible. This planning is an integral part of scientific inquiry; it is not just a preparation phase. It is one of the things that distinguishes scientific inquiry from many everyday learning experiences. Finally, these steps must be taken beforehand and the purpose of the inquiry must be articulated in advance of the experience. Clearly, scientific inquiry does not happen by accident, by just stumbling into something. Stumbling into something unexpected and interesting can happen while engaged in scientific inquiry, but learning does not depend on it and serendipity does not make the inquiry scientific.

Descriptor 2. Observing Something and Trying to Explain Why It Is the Way It Is

When we were writing this chapter and googled “scientific inquiry,” the first entry was: “Scientific inquiry refers to the diverse ways in which scientists study the natural world and propose explanations based on the evidence derived from their work.” The emphasis is on studying, or observing, and then explaining . This descriptor takes the image of scientific inquiry beyond carefully planned experience and includes explaining what was experienced.

According to the Merriam-Webster dictionary, “explain” means “(a) to make known, (b) to make plain or understandable, (c) to give the reason or cause of, and (d) to show the logical development or relations of” (Merriam-Webster, n.d. ). We will use all these definitions. Taken together, they suggest that to explain an observation means to understand it by finding reasons (or causes) for why it is as it is. In this sense of scientific inquiry, the following are synonyms: explaining why, understanding why, and reasoning about causes and effects. Our image of scientific inquiry now includes planning, observing, and explaining why.

An image represents the observation required in the scientific inquiry including planning and explaining.

We need to add a final note about this descriptor. We have phrased it in a way that suggests “observing something” means you are observing something in real time—observing the way things are or the way things are changing. This is often true. But, observing could mean observing data that already have been collected, maybe by someone else making the original observations (e.g., secondary analysis of NAEP data or analysis of existing video recordings of classroom instruction). We will address secondary analyses more fully in Chap. 4 . For now, what is important is that the process requires explaining why the data look like they do.

We must note that for us, the term “data” is not limited to numerical or quantitative data such as test scores. Data can also take many nonquantitative forms, including written survey responses, interview transcripts, journal entries, video recordings of students, teachers, and classrooms, text messages, and so forth.

An image represents the data explanation as it is not limited and takes numerous non-quantitative forms including an interview, journal entries, etc.

Exercise 1.3

What are the implications of the statement that just “observing” is not enough to count as scientific inquiry? Does this mean that a detailed description of a phenomenon is not scientific inquiry?

Find sources that define research in education that differ with our position, that say description alone, without explanation, counts as scientific research. Identify the precise points where the opinions differ. What are the best arguments for each of the positions? Which do you prefer? Why?

Descriptor 3. Updating Everyone’s Thinking in Response to More and Better Information

This descriptor focuses on a third aspect of scientific inquiry: updating and advancing the field’s understanding of phenomena that are investigated. This descriptor foregrounds a powerful characteristic of scientific inquiry: the reliability (or trustworthiness) of what is learned and the ultimate inevitability of this learning to advance human understanding of phenomena. Humans might choose not to learn from scientific inquiry, but history suggests that scientific inquiry always has the potential to advance understanding and that, eventually, humans take advantage of these new understandings.

Before exploring these bold claims a bit further, note that this descriptor uses “information” in the same way the previous two descriptors used “experience” and “observations.” These are the stuff of scientific inquiry and we will use them often, sometimes interchangeably. Frequently, we will use the term “data” to stand for all these terms.

An overriding goal of scientific inquiry is for everyone to learn from what one scientist does. Much of this book is about the methods you need to use so others have faith in what you report and can learn the same things you learned. This aspect of scientific inquiry has many implications.

One implication is that scientific inquiry is not a private practice. It is a public practice available for others to see and learn from. Notice how different this is from everyday learning. When you happen to learn something from your everyday experience, often only you gain from the experience. The fact that research is a public practice means it is also a social one. It is best conducted by interacting with others along the way: soliciting feedback at each phase, taking opportunities to present work-in-progress, and benefitting from the advice of others.

A second implication is that you, as the researcher, must be committed to sharing what you are doing and what you are learning in an open and transparent way. This allows all phases of your work to be scrutinized and critiqued. This is what gives your work credibility. The reliability or trustworthiness of your findings depends on your colleagues recognizing that you have used all appropriate methods to maximize the chances that your claims are justified by the data.

A third implication of viewing scientific inquiry as a collective enterprise is the reverse of the second—you must be committed to receiving comments from others. You must treat your colleagues as fair and honest critics even though it might sometimes feel otherwise. You must appreciate their job, which is to remain skeptical while scrutinizing what you have done in considerable detail. To provide the best help to you, they must remain skeptical about your conclusions (when, for example, the data are difficult for them to interpret) until you offer a convincing logical argument based on the information you share. A rather harsh but good-to-remember statement of the role of your friendly critics was voiced by Karl Popper, a well-known twentieth century philosopher of science: “. . . if you are interested in the problem which I tried to solve by my tentative assertion, you may help me by criticizing it as severely as you can” (Popper, 1968, p. 27).

A final implication of this third descriptor is that, as someone engaged in scientific inquiry, you have no choice but to update your thinking when the data support a different conclusion. This applies to your own data as well as to those of others. When data clearly point to a specific claim, even one that is quite different than you expected, you must reconsider your position. If the outcome is replicated multiple times, you need to adjust your thinking accordingly. Scientific inquiry does not let you pick and choose which data to believe; it mandates that everyone update their thinking when the data warrant an update.

Doing Scientific Inquiry

We define scientific inquiry in an operational sense—what does it mean to do scientific inquiry? What kind of process would satisfy all three descriptors: carefully planning an experience in advance; observing and trying to explain what you see; and, contributing to updating everyone’s thinking about an important phenomenon?

We define scientific inquiry as formulating , testing , and revising hypotheses about phenomena of interest.

Of course, we are not the only ones who define it in this way. The definition for the scientific method posted by the editors of Britannica is: “a researcher develops a hypothesis, tests it through various means, and then modifies the hypothesis on the basis of the outcome of the tests and experiments” (Britannica, n.d. ).

An image represents the scientific inquiry definition given by the editors of Britannica and also defines the hypothesis on the basis of the experiments.

Notice how defining scientific inquiry this way satisfies each of the descriptors. “Carefully planning an experience in advance” is exactly what happens when formulating a hypothesis about a phenomenon of interest and thinking about how to test it. “ Observing a phenomenon” occurs when testing a hypothesis, and “ explaining ” what is found is required when revising a hypothesis based on the data. Finally, “updating everyone’s thinking” comes from comparing publicly the original with the revised hypothesis.

Doing scientific inquiry, as we have defined it, underscores the value of accumulating knowledge rather than generating random bits of knowledge. Formulating, testing, and revising hypotheses is an ongoing process, with each revised hypothesis begging for another test, whether by the same researcher or by new researchers. The editors of Britannica signaled this cyclic process by adding the following phrase to their definition of the scientific method: “The modified hypothesis is then retested, further modified, and tested again.” Scientific inquiry creates a process that encourages each study to build on the studies that have gone before. Through collective engagement in this process of building study on top of study, the scientific community works together to update its thinking.

Before exploring more fully the meaning of “formulating, testing, and revising hypotheses,” we need to acknowledge that this is not the only way researchers define research. Some researchers prefer a less formal definition, one that includes more serendipity, less planning, less explanation. You might have come across more open definitions such as “research is finding out about something.” We prefer the tighter hypothesis formulation, testing, and revision definition because we believe it provides a single, coherent map for conducting research that addresses many of the thorny problems educational researchers encounter. We believe it is the most useful orientation toward research and the most helpful to learn as a beginning researcher.

A final clarification of our definition is that it applies equally to qualitative and quantitative research. This is a familiar distinction in education that has generated much discussion. You might think our definition favors quantitative methods over qualitative methods because the language of hypothesis formulation and testing is often associated with quantitative methods. In fact, we do not favor one method over another. In Chap. 4 , we will illustrate how our definition fits research using a range of quantitative and qualitative methods.

Exercise 1.4

Look for ways to extend what the field knows in an area that has already received attention by other researchers. Specifically, you can search for a program of research carried out by more experienced researchers that has some revised hypotheses that remain untested. Identify a revised hypothesis that you might like to test.

Unpacking the Terms Formulating, Testing, and Revising Hypotheses

To get a full sense of the definition of scientific inquiry we will use throughout this book, it is helpful to spend a little time with each of the key terms.

We first want to make clear that we use the term “hypothesis” as it is defined in most dictionaries and as it used in many scientific fields rather than as it is usually defined in educational statistics courses. By “hypothesis,” we do not mean a null hypothesis that is accepted or rejected by statistical analysis. Rather, we use “hypothesis” in the sense conveyed by the following definitions: “An idea or explanation for something that is based on known facts but has not yet been proved” (Cambridge University Press, n.d. ), and “An unproved theory, proposition, or supposition, tentatively accepted to explain certain facts and to provide a basis for further investigation or argument” (Agnes & Guralnik, 2008 ).

We distinguish two parts to “hypotheses.” Hypotheses consist of predictions and rationales . Predictions are statements about what you expect to find when you inquire about something. Rationales are explanations for why you made the predictions you did, why you believe your predictions are correct. So, for us “formulating hypotheses” means making explicit predictions and developing rationales for the predictions.

“Testing hypotheses” means making observations that allow you to assess in what ways your predictions were correct and in what ways they were incorrect. In education research, it is rarely useful to think of your predictions as either right or wrong. Because of the complexity of most issues you will investigate, most predictions will be right in some ways and wrong in others.

By studying the observations you make (data you collect) to test your hypotheses, you can revise your hypotheses to better align with the observations. This means revising your predictions plus revising your rationales to justify your adjusted predictions. Even though you might not run another test, formulating revised hypotheses is an essential part of conducting a research study. Comparing your original and revised hypotheses informs everyone of what you learned by conducting your study. In addition, a revised hypothesis sets the stage for you or someone else to extend your study and accumulate more knowledge of the phenomenon.

We should note that not everyone makes a clear distinction between predictions and rationales as two aspects of hypotheses. In fact, common, non-scientific uses of the word “hypothesis” may limit it to only a prediction or only an explanation (or rationale). We choose to explicitly include both prediction and rationale in our definition of hypothesis, not because we assert this should be the universal definition, but because we want to foreground the importance of both parts acting in concert. Using “hypothesis” to represent both prediction and rationale could hide the two aspects, but we make them explicit because they provide different kinds of information. It is usually easier to make predictions than develop rationales because predictions can be guesses, hunches, or gut feelings about which you have little confidence. Developing a compelling rationale requires careful thought plus reading what other researchers have found plus talking with your colleagues. Often, while you are developing your rationale you will find good reasons to change your predictions. Developing good rationales is the engine that drives scientific inquiry. Rationales are essentially descriptions of how much you know about the phenomenon you are studying. Throughout this guide, we will elaborate on how developing good rationales drives scientific inquiry. For now, we simply note that it can sharpen your predictions and help you to interpret your data as you test your hypotheses.

An image represents the rationale and the prediction for the scientific inquiry and different types of information provided by the terms.

Hypotheses in education research take a variety of forms or types. This is because there are a variety of phenomena that can be investigated. Investigating educational phenomena is sometimes best done using qualitative methods, sometimes using quantitative methods, and most often using mixed methods (e.g., Hay, 2016 ; Weis et al. 2019a ; Weisner, 2005 ). This means that, given our definition, hypotheses are equally applicable to qualitative and quantitative investigations.

Hypotheses take different forms when they are used to investigate different kinds of phenomena. Two very different activities in education could be labeled conducting experiments and descriptions. In an experiment, a hypothesis makes a prediction about anticipated changes, say the changes that occur when a treatment or intervention is applied. You might investigate how students’ thinking changes during a particular kind of instruction.

A second type of hypothesis, relevant for descriptive research, makes a prediction about what you will find when you investigate and describe the nature of a situation. The goal is to understand a situation as it exists rather than to understand a change from one situation to another. In this case, your prediction is what you expect to observe. Your rationale is the set of reasons for making this prediction; it is your current explanation for why the situation will look like it does.

You will probably read, if you have not already, that some researchers say you do not need a prediction to conduct a descriptive study. We will discuss this point of view in Chap. 2 . For now, we simply claim that scientific inquiry, as we have defined it, applies to all kinds of research studies. Descriptive studies, like others, not only benefit from formulating, testing, and revising hypotheses, but also need hypothesis formulating, testing, and revising.

One reason we define research as formulating, testing, and revising hypotheses is that if you think of research in this way you are less likely to go wrong. It is a useful guide for the entire process, as we will describe in detail in the chapters ahead. For example, as you build the rationale for your predictions, you are constructing the theoretical framework for your study (Chap. 3 ). As you work out the methods you will use to test your hypothesis, every decision you make will be based on asking, “Will this help me formulate or test or revise my hypothesis?” (Chap. 4 ). As you interpret the results of testing your predictions, you will compare them to what you predicted and examine the differences, focusing on how you must revise your hypotheses (Chap. 5 ). By anchoring the process to formulating, testing, and revising hypotheses, you will make smart decisions that yield a coherent and well-designed study.

Exercise 1.5

Compare the concept of formulating, testing, and revising hypotheses with the descriptions of scientific inquiry contained in Scientific Research in Education (NRC, 2002 ). How are they similar or different?

Exercise 1.6

Provide an example to illustrate and emphasize the differences between everyday learning/thinking and scientific inquiry.

Learning from Doing Scientific Inquiry

We noted earlier that a measure of what you have learned by conducting a research study is found in the differences between your original hypothesis and your revised hypothesis based on the data you collected to test your hypothesis. We will elaborate this statement in later chapters, but we preview our argument here.

Even before collecting data, scientific inquiry requires cycles of making a prediction, developing a rationale, refining your predictions, reading and studying more to strengthen your rationale, refining your predictions again, and so forth. And, even if you have run through several such cycles, you still will likely find that when you test your prediction you will be partly right and partly wrong. The results will support some parts of your predictions but not others, or the results will “kind of” support your predictions. A critical part of scientific inquiry is making sense of your results by interpreting them against your predictions. Carefully describing what aspects of your data supported your predictions, what aspects did not, and what data fell outside of any predictions is not an easy task, but you cannot learn from your study without doing this analysis.

An image represents the cycle of events that take place before making predictions, developing the rationale, and studying the prediction and rationale multiple times.

Analyzing the matches and mismatches between your predictions and your data allows you to formulate different rationales that would have accounted for more of the data. The best revised rationale is the one that accounts for the most data. Once you have revised your rationales, you can think about the predictions they best justify or explain. It is by comparing your original rationales to your new rationales that you can sort out what you learned from your study.

Suppose your study was an experiment. Maybe you were investigating the effects of a new instructional intervention on students’ learning. Your original rationale was your explanation for why the intervention would change the learning outcomes in a particular way. Your revised rationale explained why the changes that you observed occurred like they did and why your revised predictions are better. Maybe your original rationale focused on the potential of the activities if they were implemented in ideal ways and your revised rationale included the factors that are likely to affect how teachers implement them. By comparing the before and after rationales, you are describing what you learned—what you can explain now that you could not before. Another way of saying this is that you are describing how much more you understand now than before you conducted your study.

Revised predictions based on carefully planned and collected data usually exhibit some of the following features compared with the originals: more precision, more completeness, and broader scope. Revised rationales have more explanatory power and become more complete, more aligned with the new predictions, sharper, and overall more convincing.

Part II. Why Do Educators Do Research?

Doing scientific inquiry is a lot of work. Each phase of the process takes time, and you will often cycle back to improve earlier phases as you engage in later phases. Because of the significant effort required, you should make sure your study is worth it. So, from the beginning, you should think about the purpose of your study. Why do you want to do it? And, because research is a social practice, you should also think about whether the results of your study are likely to be important and significant to the education community.

If you are doing research in the way we have described—as scientific inquiry—then one purpose of your study is to understand , not just to describe or evaluate or report. As we noted earlier, when you formulate hypotheses, you are developing rationales that explain why things might be like they are. In our view, trying to understand and explain is what separates research from other kinds of activities, like evaluating or describing.

One reason understanding is so important is that it allows researchers to see how or why something works like it does. When you see how something works, you are better able to predict how it might work in other contexts, under other conditions. And, because conditions, or contextual factors, matter a lot in education, gaining insights into applying your findings to other contexts increases the contributions of your work and its importance to the broader education community.

Consequently, the purposes of research studies in education often include the more specific aim of identifying and understanding the conditions under which the phenomena being studied work like the observations suggest. A classic example of this kind of study in mathematics education was reported by William Brownell and Harold Moser in 1949 . They were trying to establish which method of subtracting whole numbers could be taught most effectively—the regrouping method or the equal additions method. However, they realized that effectiveness might depend on the conditions under which the methods were taught—“meaningfully” versus “mechanically.” So, they designed a study that crossed the two instructional approaches with the two different methods (regrouping and equal additions). Among other results, they found that these conditions did matter. The regrouping method was more effective under the meaningful condition than the mechanical condition, but the same was not true for the equal additions algorithm.

What do education researchers want to understand? In our view, the ultimate goal of education is to offer all students the best possible learning opportunities. So, we believe the ultimate purpose of scientific inquiry in education is to develop understanding that supports the improvement of learning opportunities for all students. We say “ultimate” because there are lots of issues that must be understood to improve learning opportunities for all students. Hypotheses about many aspects of education are connected, ultimately, to students’ learning. For example, formulating and testing a hypothesis that preservice teachers need to engage in particular kinds of activities in their coursework in order to teach particular topics well is, ultimately, connected to improving students’ learning opportunities. So is hypothesizing that school districts often devote relatively few resources to instructional leadership training or hypothesizing that positioning mathematics as a tool students can use to combat social injustice can help students see the relevance of mathematics to their lives.

We do not exclude the importance of research on educational issues more removed from improving students’ learning opportunities, but we do think the argument for their importance will be more difficult to make. If there is no way to imagine a connection between your hypothesis and improving learning opportunities for students, even a distant connection, we recommend you reconsider whether it is an important hypothesis within the education community.

Notice that we said the ultimate goal of education is to offer all students the best possible learning opportunities. For too long, educators have been satisfied with a goal of offering rich learning opportunities for lots of students, sometimes even for just the majority of students, but not necessarily for all students. Evaluations of success often are based on outcomes that show high averages. In other words, if many students have learned something, or even a smaller number have learned a lot, educators may have been satisfied. The problem is that there is usually a pattern in the groups of students who receive lower quality opportunities—students of color and students who live in poor areas, urban and rural. This is not acceptable. Consequently, we emphasize the premise that the purpose of education research is to offer rich learning opportunities to all students.

One way to make sure you will be able to convince others of the importance of your study is to consider investigating some aspect of teachers’ shared instructional problems. Historically, researchers in education have set their own research agendas, regardless of the problems teachers are facing in schools. It is increasingly recognized that teachers have had trouble applying to their own classrooms what researchers find. To address this problem, a researcher could partner with a teacher—better yet, a small group of teachers—and talk with them about instructional problems they all share. These discussions can create a rich pool of problems researchers can consider. If researchers pursued one of these problems (preferably alongside teachers), the connection to improving learning opportunities for all students could be direct and immediate. “Grounding a research question in instructional problems that are experienced across multiple teachers’ classrooms helps to ensure that the answer to the question will be of sufficient scope to be relevant and significant beyond the local context” (Cai et al., 2019b , p. 115).

As a beginning researcher, determining the relevance and importance of a research problem is especially challenging. We recommend talking with advisors, other experienced researchers, and peers to test the educational importance of possible research problems and topics of study. You will also learn much more about the issue of research importance when you read Chap. 5 .

Exercise 1.7

Identify a problem in education that is closely connected to improving learning opportunities and a problem that has a less close connection. For each problem, write a brief argument (like a logical sequence of if-then statements) that connects the problem to all students’ learning opportunities.

Part III. Conducting Research as a Practice of Failing Productively

Scientific inquiry involves formulating hypotheses about phenomena that are not fully understood—by you or anyone else. Even if you are able to inform your hypotheses with lots of knowledge that has already been accumulated, you are likely to find that your prediction is not entirely accurate. This is normal. Remember, scientific inquiry is a process of constantly updating your thinking. More and better information means revising your thinking, again, and again, and again. Because you never fully understand a complicated phenomenon and your hypotheses never produce completely accurate predictions, it is easy to believe you are somehow failing.

The trick is to fail upward, to fail to predict accurately in ways that inform your next hypothesis so you can make a better prediction. Some of the best-known researchers in education have been open and honest about the many times their predictions were wrong and, based on the results of their studies and those of others, they continuously updated their thinking and changed their hypotheses.

A striking example of publicly revising (actually reversing) hypotheses due to incorrect predictions is found in the work of Lee J. Cronbach, one of the most distinguished educational psychologists of the twentieth century. In 1955, Cronbach delivered his presidential address to the American Psychological Association. Titling it “Two Disciplines of Scientific Psychology,” Cronbach proposed a rapprochement between two research approaches—correlational studies that focused on individual differences and experimental studies that focused on instructional treatments controlling for individual differences. (We will examine different research approaches in Chap. 4 ). If these approaches could be brought together, reasoned Cronbach ( 1957 ), researchers could find interactions between individual characteristics and treatments (aptitude-treatment interactions or ATIs), fitting the best treatments to different individuals.

In 1975, after years of research by many researchers looking for ATIs, Cronbach acknowledged the evidence for simple, useful ATIs had not been found. Even when trying to find interactions between a few variables that could provide instructional guidance, the analysis, said Cronbach, creates “a hall of mirrors that extends to infinity, tormenting even the boldest investigators and defeating even ambitious designs” (Cronbach, 1975 , p. 119).

As he was reflecting back on his work, Cronbach ( 1986 ) recommended moving away from documenting instructional effects through statistical inference (an approach he had championed for much of his career) and toward approaches that probe the reasons for these effects, approaches that provide a “full account of events in a time, place, and context” (Cronbach, 1986 , p. 104). This is a remarkable change in hypotheses, a change based on data and made fully transparent. Cronbach understood the value of failing productively.

Closer to home, in a less dramatic example, one of us began a line of scientific inquiry into how to prepare elementary preservice teachers to teach early algebra. Teaching early algebra meant engaging elementary students in early forms of algebraic reasoning. Such reasoning should help them transition from arithmetic to algebra. To begin this line of inquiry, a set of activities for preservice teachers were developed. Even though the activities were based on well-supported hypotheses, they largely failed to engage preservice teachers as predicted because of unanticipated challenges the preservice teachers faced. To capitalize on this failure, follow-up studies were conducted, first to better understand elementary preservice teachers’ challenges with preparing to teach early algebra, and then to better support preservice teachers in navigating these challenges. In this example, the initial failure was a necessary step in the researchers’ scientific inquiry and furthered the researchers’ understanding of this issue.

We present another example of failing productively in Chap. 2 . That example emerges from recounting the history of a well-known research program in mathematics education.

Making mistakes is an inherent part of doing scientific research. Conducting a study is rarely a smooth path from beginning to end. We recommend that you keep the following things in mind as you begin a career of conducting research in education.

First, do not get discouraged when you make mistakes; do not fall into the trap of feeling like you are not capable of doing research because you make too many errors.

Second, learn from your mistakes. Do not ignore your mistakes or treat them as errors that you simply need to forget and move past. Mistakes are rich sites for learning—in research just as in other fields of study.

Third, by reflecting on your mistakes, you can learn to make better mistakes, mistakes that inform you about a productive next step. You will not be able to eliminate your mistakes, but you can set a goal of making better and better mistakes.

Exercise 1.8

How does scientific inquiry differ from everyday learning in giving you the tools to fail upward? You may find helpful perspectives on this question in other resources on science and scientific inquiry (e.g., Failure: Why Science is So Successful by Firestein, 2015).

Exercise 1.9

Use what you have learned in this chapter to write a new definition of scientific inquiry. Compare this definition with the one you wrote before reading this chapter. If you are reading this book as part of a course, compare your definition with your colleagues’ definitions. Develop a consensus definition with everyone in the course.

Part IV. Preview of Chap. 2

Now that you have a good idea of what research is, at least of what we believe research is, the next step is to think about how to actually begin doing research. This means how to begin formulating, testing, and revising hypotheses. As for all phases of scientific inquiry, there are lots of things to think about. Because it is critical to start well, we devote Chap. 2 to getting started with formulating hypotheses.

Scientific Research

Scientific Research

Definition:

Scientific research is the systematic and empirical investigation of phenomena, theories, or hypotheses, using various methods and techniques in order to acquire new knowledge or to validate existing knowledge.

It involves the collection, analysis, interpretation, and presentation of data, as well as the formulation and testing of hypotheses. Scientific research can be conducted in various fields, such as natural sciences, social sciences, and engineering, and may involve experiments, observations, surveys, or other forms of data collection. The goal of scientific research is to advance knowledge, improve understanding, and contribute to the development of solutions to practical problems.

Types of Scientific Research

There are different types of scientific research, which can be classified based on their purpose, method, and application. In this response, we will discuss the four main types of scientific research.

Descriptive Research

Descriptive research aims to describe or document a particular phenomenon or situation, without altering it in any way. This type of research is usually done through observation, surveys, or case studies. Descriptive research is useful in generating ideas, understanding complex phenomena, and providing a foundation for future research. However, it does not provide explanations or causal relationships between variables.

Exploratory Research

Exploratory research aims to explore a new area of inquiry or develop initial ideas for future research. This type of research is usually conducted through observation, interviews, or focus groups. Exploratory research is useful in generating hypotheses, identifying research questions, and determining the feasibility of a larger study. However, it does not provide conclusive evidence or establish cause-and-effect relationships.

Experimental Research

Experimental research aims to test cause-and-effect relationships between variables by manipulating one variable and observing the effects on another variable. This type of research involves the use of an experimental group, which receives a treatment, and a control group, which does not receive the treatment. Experimental research is useful in establishing causal relationships, replicating results, and controlling extraneous variables. However, it may not be feasible or ethical to manipulate certain variables in some contexts.

Correlational Research

Correlational research aims to examine the relationship between two or more variables without manipulating them. This type of research involves the use of statistical techniques to determine the strength and direction of the relationship between variables. Correlational research is useful in identifying patterns, predicting outcomes, and testing theories. However, it does not establish causation or control for confounding variables.

Scientific Research Methods

Scientific research methods are used in scientific research to investigate phenomena, acquire knowledge, and answer questions using empirical evidence. Here are some commonly used scientific research methods:

Observational Studies

This method involves observing and recording phenomena as they occur in their natural setting. It can be done through direct observation or by using tools such as cameras, microscopes, or sensors.

Experimental Studies

This method involves manipulating one or more variables to determine the effect on the outcome. This type of study is often used to establish cause-and-effect relationships.

Survey Research

This method involves collecting data from a large number of people by asking them a set of standardized questions. Surveys can be conducted in person, over the phone, or online.

Case Studies

This method involves in-depth analysis of a single individual, group, or organization. Case studies are often used to gain insights into complex or unusual phenomena.

Meta-analysis

This method involves combining data from multiple studies to arrive at a more reliable conclusion. This technique can be used to identify patterns and trends across a large number of studies.

Qualitative Research

This method involves collecting and analyzing non-numerical data, such as interviews, focus groups, or observations. This type of research is often used to explore complex phenomena and to gain an understanding of people’s experiences and perspectives.

Quantitative Research

This method involves collecting and analyzing numerical data using statistical techniques. This type of research is often used to test hypotheses and to establish cause-and-effect relationships.

Longitudinal Studies

This method involves following a group of individuals over a period of time to observe changes and to identify patterns and trends. This type of study can be used to investigate the long-term effects of a particular intervention or exposure.

Data Analysis Methods

There are many different data analysis methods used in scientific research, and the choice of method depends on the type of data being collected and the research question. Here are some commonly used data analysis methods:

  • Descriptive statistics: This involves using summary statistics such as mean, median, mode, standard deviation, and range to describe the basic features of the data.
  • Inferential statistics: This involves using statistical tests to make inferences about a population based on a sample of data. Examples of inferential statistics include t-tests, ANOVA, and regression analysis.
  • Qualitative analysis: This involves analyzing non-numerical data such as interviews, focus groups, and observations. Qualitative analysis may involve identifying themes, patterns, or categories in the data.
  • Content analysis: This involves analyzing the content of written or visual materials such as articles, speeches, or images. Content analysis may involve identifying themes, patterns, or categories in the content.
  • Data mining: This involves using automated methods to analyze large datasets to identify patterns, trends, or relationships in the data.
  • Machine learning: This involves using algorithms to analyze data and make predictions or classifications based on the patterns identified in the data.

Application of Scientific Research

Scientific research has numerous applications in many fields, including:

  • Medicine and healthcare: Scientific research is used to develop new drugs, medical treatments, and vaccines. It is also used to understand the causes and risk factors of diseases, as well as to develop new diagnostic tools and medical devices.
  • Agriculture : Scientific research is used to develop new crop varieties, to improve crop yields, and to develop more sustainable farming practices.
  • Technology and engineering : Scientific research is used to develop new technologies and engineering solutions, such as renewable energy systems, new materials, and advanced manufacturing techniques.
  • Environmental science : Scientific research is used to understand the impacts of human activity on the environment and to develop solutions for mitigating those impacts. It is also used to monitor and manage natural resources, such as water and air quality.
  • Education : Scientific research is used to develop new teaching methods and educational materials, as well as to understand how people learn and develop.
  • Business and economics: Scientific research is used to understand consumer behavior, to develop new products and services, and to analyze economic trends and policies.
  • Social sciences : Scientific research is used to understand human behavior, attitudes, and social dynamics. It is also used to develop interventions to improve social welfare and to inform public policy.

How to Conduct Scientific Research

Conducting scientific research involves several steps, including:

  • Identify a research question: Start by identifying a question or problem that you want to investigate. This question should be clear, specific, and relevant to your field of study.
  • Conduct a literature review: Before starting your research, conduct a thorough review of existing research in your field. This will help you identify gaps in knowledge and develop hypotheses or research questions.
  • Develop a research plan: Once you have a research question, develop a plan for how you will collect and analyze data to answer that question. This plan should include a detailed methodology, a timeline, and a budget.
  • Collect data: Depending on your research question and methodology, you may collect data through surveys, experiments, observations, or other methods.
  • Analyze data: Once you have collected your data, analyze it using appropriate statistical or qualitative methods. This will help you draw conclusions about your research question.
  • Interpret results: Based on your analysis, interpret your results and draw conclusions about your research question. Discuss any limitations or implications of your findings.
  • Communicate results: Finally, communicate your findings to others in your field through presentations, publications, or other means.

Purpose of Scientific Research

The purpose of scientific research is to systematically investigate phenomena, acquire new knowledge, and advance our understanding of the world around us. Scientific research has several key goals, including:

  • Exploring the unknown: Scientific research is often driven by curiosity and the desire to explore uncharted territory. Scientists investigate phenomena that are not well understood, in order to discover new insights and develop new theories.
  • Testing hypotheses: Scientific research involves developing hypotheses or research questions, and then testing them through observation and experimentation. This allows scientists to evaluate the validity of their ideas and refine their understanding of the phenomena they are studying.
  • Solving problems: Scientific research is often motivated by the desire to solve practical problems or address real-world challenges. For example, researchers may investigate the causes of a disease in order to develop new treatments, or explore ways to make renewable energy more affordable and accessible.
  • Advancing knowledge: Scientific research is a collective effort to advance our understanding of the world around us. By building on existing knowledge and developing new insights, scientists contribute to a growing body of knowledge that can be used to inform decision-making, solve problems, and improve our lives.

Examples of Scientific Research

Here are some examples of scientific research that are currently ongoing or have recently been completed:

  • Clinical trials for new treatments: Scientific research in the medical field often involves clinical trials to test new treatments for diseases and conditions. For example, clinical trials may be conducted to evaluate the safety and efficacy of new drugs or medical devices.
  • Genomics research: Scientists are conducting research to better understand the human genome and its role in health and disease. This includes research on genetic mutations that can cause diseases such as cancer, as well as the development of personalized medicine based on an individual’s genetic makeup.
  • Climate change: Scientific research is being conducted to understand the causes and impacts of climate change, as well as to develop solutions for mitigating its effects. This includes research on renewable energy technologies, carbon capture and storage, and sustainable land use practices.
  • Neuroscience : Scientists are conducting research to understand the workings of the brain and the nervous system, with the goal of developing new treatments for neurological disorders such as Alzheimer’s disease and Parkinson’s disease.
  • Artificial intelligence: Researchers are working to develop new algorithms and technologies to improve the capabilities of artificial intelligence systems. This includes research on machine learning, computer vision, and natural language processing.
  • Space exploration: Scientific research is being conducted to explore the cosmos and learn more about the origins of the universe. This includes research on exoplanets, black holes, and the search for extraterrestrial life.

When to use Scientific Research

Some specific situations where scientific research may be particularly useful include:

  • Solving problems: Scientific research can be used to investigate practical problems or address real-world challenges. For example, scientists may investigate the causes of a disease in order to develop new treatments, or explore ways to make renewable energy more affordable and accessible.
  • Decision-making: Scientific research can provide evidence-based information to inform decision-making. For example, policymakers may use scientific research to evaluate the effectiveness of different policy options or to make decisions about public health and safety.
  • Innovation : Scientific research can be used to develop new technologies, products, and processes. For example, research on materials science can lead to the development of new materials with unique properties that can be used in a range of applications.
  • Knowledge creation : Scientific research is an important way of generating new knowledge and advancing our understanding of the world around us. This can lead to new theories, insights, and discoveries that can benefit society.

Advantages of Scientific Research

There are many advantages of scientific research, including:

  • Improved understanding : Scientific research allows us to gain a deeper understanding of the world around us, from the smallest subatomic particles to the largest celestial bodies.
  • Evidence-based decision making: Scientific research provides evidence-based information that can inform decision-making in many fields, from public policy to medicine.
  • Technological advancements: Scientific research drives technological advancements in fields such as medicine, engineering, and materials science. These advancements can improve quality of life, increase efficiency, and reduce costs.

Limitations of Scientific Research

Scientific research has some limitations that researchers should be aware of. These limitations can include:

  • Research design limitations : The design of a research study can impact the reliability and validity of the results. Poorly designed studies can lead to inaccurate or inconclusive results. Researchers must carefully consider the study design to ensure that it is appropriate for the research question and the population being studied.
  • Sample size limitations: The size of the sample being studied can impact the generalizability of the results. Small sample sizes may not be representative of the larger population, and may lead to incorrect conclusions.
  • Time and resource limitations: Scientific research can be costly and time-consuming. Researchers may not have the resources necessary to conduct a large-scale study, or may not have sufficient time to complete a study with appropriate controls and analysis.
  • Ethical limitations : Certain types of research may raise ethical concerns, such as studies involving human or animal subjects. Ethical concerns may limit the scope of the research that can be conducted, or require additional protocols and procedures to ensure the safety and well-being of participants.
  • Limitations of technology: Technology may limit the types of research that can be conducted, or the accuracy of the data collected. For example, certain types of research may require advanced technology that is not yet available, or may be limited by the accuracy of current measurement tools.
  • Limitations of existing knowledge: Existing knowledge may limit the types of research that can be conducted. For example, if there is limited knowledge in a particular field, it may be difficult to design a study that can provide meaningful results.

Arts-based research encompasses a range of research approaches and strategies that utilize one or more of the arts in investigation. Such approaches have evolved from understandings that life and experiences of the world are multifaceted, and that art offers ways of knowing the world that involve sensory perceptions and emotion as well as intellectual responses. Researchers have used arts for various stages of research. It may be to collect or create data, to interpret or analyze it, to present their findings, or some combination of these. Sometimes arts-based research is used to investigate art making or teaching in or through the arts. Sometimes it is used to explore issues in the wider social sciences. The field is a constantly evolving one, and researchers have evolved diverse ways of using the communicative and interpretative tools that processes with the arts allow. These include ways to initially bypass the need for verbal expression, to explore problems in physically embodied as well as discursive ways, to capture and express ambiguities, liminalities, and complexities, to collaborate in the refining of ideas, to transform audience perceptions, and to create surprise and engage audiences emotionally as well as critically. A common feature within the wide range of approaches is that they involve aesthetic responses.

The richness of the opportunities created by the use of arts in conducting and/or reporting research brings accompanying challenges. Among these are the political as well as the epistemological expectations placed on research, the need for audiences of research, and perhaps participants in research, to evolve ways of critically assessing the affect of as well as the information in presentations, the need to develop relevant and useful strategies for peer review of the research as well as the art, and the need to evolve ethical awareness that is consistent with the intentions and power of the arts.

Introduction

The term arts-based research is an umbrella term that covers an eclectic array of methodological and epistemological approaches. The key elements that unify this diverse body of work are: it is research; and one or more art forms or processes are involved in the doing of the research. How art is involved varies enormously. It has been used as one of several tools to elicit information (Cremin, Mason, & Busher, 2011 ; Gauntlett, 2007 ; Wang & Burns, 1997 ) and for the analysis of data (Boal, 1979 ; Gallagher, 2014 ; Neilson, 2008 ), and so it serves as an enrichment to the palette of tools used in qualitative research. It has been used in the presentation of findings (Bagley & Cancienne, 2002 ; Conrad, 2012 ; Gray & Sinding, 2002 ) and so occupies a space that could be responded to and evaluated as both art and research. It has been used to investigate art and the process of art-making. The emergence of the concept and practice of a/r/tography (Belliveau, 2015 ; Irwin, 2013 ; Springgay, Irwin, & Kind, 2005 ), for example, places art-making and its textual interpretation in a dynamic relationship of inquiry into the purpose, process, and meaning of the making of an artwork.

The field is multifaceted and elusive of definition and encompassing explanation. This article does not attempt such definitions. But it does risk describing some well-trodden pathways through the field and posing some questions. Illustrative examples are offered from the author’s work, as well as citing of works by other researchers who use arts-based approaches.

My own explorations of arts-based research began many years ago, before the term came into usage. I was commissioned to develop a touring play for a New Zealand youth theater, and I chose to write a docudrama, Broadwood: Na wai te reo? (Greenwood, 1995 ). The play reported the case of a remote, rural, and predominantly Maori school that made Maori language a compulsory subject in its curriculum. The parents of one boy argued against the decision, claiming the language held no use for their son. The dispute was aired on national television and was debated in parliament. The minister agreed that the local school board had the right to make the decision after consultation with parents and community. The dispute ended with the boy being given permission to do extra math assignments in the library during Maori language classes. To develop the script, I interviewed all the local participants in the case and sincerely sought to capture the integrity of their views in my dialogue. I accessed the minister of education’s comments through public documents and media and reserved the right to occasionally satirize them. Just a week or two before final production, the family’s lawyer officially asked for a copy of the script. To my relief, it was returned with the comment that the family felt I had captured their views quite accurately. The youth theater was invited to hold its final rehearsal on the local marae (a traditional tribal Maori ground that holds a meeting house and hosts significant community occasions), and a local elder offered the use of an ancestral whalebone weapon in the opening performance, instead of the wooden one made for the production. The opening performance took place in the school itself, and the boy, together with his parents and family friends, sat in the audience together with hundreds of community people. The play had an interactive section where the audience was asked to vote in response to a survey the school had originally sent out to its community. The majority of the audience voted for Maori language to be part of the mandatory curriculum. The boy and his family voted equally emphatically for it not to be. The play then toured in New Zealand and was taken to a festival in Australia.

At the time I saw the work purely in terms of theater—albeit with a strongly critical social function. Looking back, I now see it was a performative case study. I had carefully researched the context and respectfully interviewed participants after gaining their informed consent. The participants had all endorsed my reporting of the data. The findings were disseminated and subject to popular as well as peer review. The performances added an extra dimension to the research: they actively invited audience consideration and debate.

This article discusses the epistemology that underlies arts-based approaches to research, reviews the purposes and value of research that involves the arts, identifies different stages and ways that art may be utilized, and addresses questions that are debated in the field. It does not seek to disentangle all the threads within this approach to research or to review all key theorizations and possibilities in the field. The arena of arts-based research is a diverse and rapidly expanding one, and it is only possible within this discussion to identify some of the common underlying characteristics and potentialities and to offer selected examples. Because this discussion is shaped within an essay format, rather than through a visual or performative collage, there is the risk of marking a limited number of pathways and of making assertions. At the same time, I acknowledge that the discussion might have alternatively been conducted through arts-based media, which might better reflect some of the liminalities and interweaving layers of art-based processes (see further, Greenwood, 2016 ).

The term art itself compasses a wide and diverse spectrum of products and process. This article focuses particularly on dramatic and visual art, while acknowledging that the use of other art forms, such as poetry, fiction, dance, film, and fabric work, have been variously used in processes of investigation. The word art is used to indicate the wider spectrum of art activities and to refer to more specific forms and processes by their disciplines and conventions.

Why Use Art?

One of the main reasons for the growth of arts-based approaches to research is recognition that life experiences are multi-sensory, multifaceted, and related in complex ways to time, space, ideologies, and relationships with others. Traditional approaches to research have been seen by increasing numbers of researchers as predominantly privileging cerebral, verbal, and linearly temporal approaches to knowledge and experience. The use of art in research is one of many shifts in the search for truthful means of investigation and representation. These include, among others, movements toward various forms of narratives (Riessman, 2008 ), recognition of indigenous knowledges, and indigenous ways of sharing and using knowledge (Bharucha, 1993 ; Smith, 2014 ), auto-ethnographies (Ellis, 2004 ), conceptualizations of wicked questions (Rittel & Webber, 1973 ), processes of troubling (Gardiner, 2015 ), and queering (Halperin, 2003 ). Preissle ( 2011 ) writes about the “qualitative tapestry” (p. 689) and identifies historic and contemporary threads of epistemological challenges, methods, and purposes, pointing out the ever-increasing diversity in the field. Denzin and Lincoln ( 2011 ) describe qualitative research as a site of multiple interpretative practices and, citing St. Pierre’s ( 2004 ) argument that we are in a post “post” period, assert that “we are in a new age where messy, uncertain multi-voiced texts, cultural criticism, and new experimental works will become more common, as will more reflexive forms of fieldwork, analysis and intertextual representation” (p. 15). Springgay, Irwin, and Kind ( 2005 ) assert that a/r/tography is not a new branch of qualitative research but a methodology in its own right, and that it conceptualizes inquiry as an embodied encounter through visual and textual experiences. The use of art in research is a succession of approaches to develop methodology that is meaningful and useful.

Art, product, and process allow and even invite art-makers to explore and play with knowing and meaning in ways that are more visceral and interactive than the intellectual and verbal ways that have tended to predominate in Western discourses of knowledge. It invites art viewers to interact with representations in ways that involve their senses, emotions, and ideas. Eisner ( 1998 , 2002 ) makes a number of significant assertions about the relationship between form and knowledge that emphasize the importance of art processes in offering expanded understandings of “what it means to know” (Eisner, 1998 , p. 1). He states: “There are multiple ways in which the world can be known: Artists, writers, and dancers, as well as scientists, have important thongs to tell about the world” (p. 7). Like other constructivists (Bruner, 1990 ; Guba, 1996 ), he further argues that because human knowledge is a constructed form of experience, it is a reflection of mind as well as nature, that knowledge is made, not simply discovered. He then reasons that “the forms through which humans represent their conception of the world have a major influence on what they are able to say about it” (p. 6), and, making particular reference to education, he states that whichever particular forms of representation become acceptable “is as much a political matter as an epistemological one” (p. 7). Eisner’s arguments to extend conceptualizations of knowledge within the field of education have been echoed in the practices of art-based researchers.

Artists themselves understand through their practice that art is way of coming to know the world and of presenting that knowing, emergent and shifting though it may be, to others. Sometimes the process of coming to know takes the form of social analysis. In Guernica , as a well-known example, Picasso scrutinizes and crystallizes the brutal betrayals and waste of war. In Caucasian Chalk Circle , Brecht fractures and strips bare ideas of justice, loyalty, and ownership. Their respective visual and dramatic montages speak in ways that are different from and arguably more potent than discursive descriptions.

In many indigenous cultures, art forms are primary ways of processing and recording communally significant information and signifying relationships. For New Zealand Māori, the meeting house, with its visual images, poetry, song, oratory, and rituals, is the repository library of mythic and genealogical history and of the accumulated legacies of meetings, contested positions, and nuanced consensual decisions. Art within Māori and other indigenous culture is not an illustrative addition to knowledge systems, it is an integral means of meaning making and recording.

One of the characteristics of arts and arts-based research projects is that they engage with aesthetic understandings as well as with discursive explanations. The aesthetic is a contested term (Greenwood, 2011 ; Hamera, 2011 ). However, it is used here to describe the engagement of senses and emotion as well as intellectual processes, and the consequent collation of semiotics and significances that are embedded in cultural awareness and are variously used by art makers and art viewers to respond to works of art. An aesthetic response thus is a visceral as well as rational one. It may be comfortable with ambiguities, and it may elude verbalization.

The processes of art-making demand a commitment to a continuous refinement of skills and awareness. Art-viewers arguably also gain more from an artwork as they acquire the skills and literacies involved with that particular art form and as they gain confidence to engage with the aesthetic. However, viewers may apprehend meaning without mastery of all the relevant literacies. I recall an experience of watching flamenco in El Puerto de Santa Maria, a township outside Cadiz. My senses drank in the white stone of former monastery walls and the darkening sky over an open inner courtyard. My muscles and emotions responded spontaneously to the urgency of the guitar and the beaten rhythms on a packing case drum. My nerves tensed as the singer’s voice cut through the air. The two dancers, both older and dressed in seemingly causal fawn and grey, riveted my attention. I was a stranger to the art form, and I did not know the language of the dance and could not recognize its phases or its allusions. I did feel the visceral tug of emotion across space. My heart and soul responded to something urgent, strangely oppressive, but indefinable that might have an apprehension of what those who understand flamenco call duende . If I was more literate in the art form, I would no doubt have understood a lot more, but the art, performed by those who did know and had mastered its intricacies, communicated an experience of their world to me despite my lack of training. In that evening, I learned more about the experience of life in southern Spain than I had in my earlier pursuit of library books and websites.

Art, thus, is positioned as a powerful tool that calls for ever-refining expertise in its making, but that can communicate, at differing levels, even with those who do not have that expertise. Researchers who use art draw on its rich, and sometimes complex and elusive, epistemological bases to explore and represent aspects of the world. The researchers may themselves be artists; at the least, they need to know enough of an art form to be aware of its potential and how to manipulate it. In some cases intended participants and audiences may also be artists, but often they are not. It is the researcher who creates a framework in which participants join in the art or in which audiences receive it.

Art, Research Purpose, and Research Validity

So far, the argument for the value of art as a way of knowing is multifarious, embodied, and tolerant of ambivalences and ambiguities. Where then are the rigors that are widely held as essential for research? It can be argued that arts-based research, to be considered as research, needs to have explicit research purpose and needs to subject itself to peer critique.

As has been widely noted (Eisner, 1998 ; Leavy, 2017 ; Sullivan, 2010 ), the making of art involves some investigation, both into the process of making and into some aspect of the experiential world. In research, that purpose needs to be overt and explicit. When the purpose is identified, then the choice of methods can be open to critical scrutiny and evaluation. The design of an arts-based research project is shaped, at its core, by similar considerations as other research.

Arts-based research needs to be explicit about what is being investigated. If the objective is not clear, then the result may still be art, but it is hard to call it research. Purpose determines which of the vast array of art strategies and processes will be selected as the research methods. The trustworthiness of any research depends on a number of factors: at the design stage, it depends on a clear alignment between the purpose of the research and the methods selected to carry out the investigation. In arts-based research, as in other research, it is vital that the researcher identifies the relationship between purpose and selected art tools, and offers recipients of the research clear means to evaluate and critique the reliability and usefulness of the answers that come from the research. This is where choices about strategies need to be clearly identified and explained, and both the aims and boundaries of the investigation need to be identified.

This does not imply need for a rigid and static design. Art is an evolving process, and the research design can well be an evolving one, as is the case with participatory action research (Bryndon-Miller, Karl, Maguire, Noffke, & Sabhlok, 2011 ), bricolage (Denzin & Lincoln, 2011 ), and a number of other research approaches. However, the strategic stages and choices of the emergent design donot need to be identified and explained. Nor does it imply that all data or findings need to be fully explicable verbally. One of the reasons for choosing arts-based methods, although not the only one, is to allow the operation of aesthetic and subconscious understandings as well as conscious and verbalized ones. That is part of the epistemological justification for choosing an arts-based approach. The ambivalences and pregnant possibilities that result may be considered valued gains from the choice of research tools, and their presence simply needs to be identified, together with explication of the boundaries of how such ambivalence and possibilities relate to the research question.

Different Kinds of Purpose

The sections of this article examine common and different areas of purpose for which arts-based research is frequently used, arranging them into three clusters and discussing some of the possibilities within each one.

The first, and perhaps largest, cluster of purposes for using arts-based research is to investigate some social (in the broadest sense of the word) issue. Such issues might, for example, include woman’s rights, school absenteeism, gang membership, cross-cultural encounters, classroom relationships, experiences of particular programs, problems in language acquisition. The methodological choices involved in this group of purposes have been repeatedly addressed (e.g., Boal, 1979 ; O’Brien & Donelan, 2008 ; Finley, 2005 ; Leavy, 2017 ; Prosser, 2011 ; Wang & Burns, 1997 ) in discussions of the use of arts-based approaches to the social sciences. The intention for using arts-based tools is to open up different, and hopefully more empowering, options for exploring the specific problem or issue, and for expressing participants’ perspectives in ways that can bypass participants’ discomfort with words or unconscious compliance with dominant discourses, or perhaps to present findings in ways that better reveal their dynamics and complexity than written reports.

Another smaller, but important, cluster of purposes is to research art-making processes or completed art works. For example, a theater director (Smithner, 2010 ) investigates the critical decisions she made in selecting and weaving together separate performance works into a theatrical collage. Or, a researcher (O’Donoghue, 2011 ) investigates how a conceptual artist working with film and video enquires into social, political, and cultural issues and how he shapes his work to provoke viewers to develop specific understandings. These kinds of studies explore the how and why of art-making, focusing on the makers’ intentions, their manipulation of the elements and affordances of their specific art field, and often engage with aesthetic as well as sociocultural dimensions of analysis. Often such studies are presented as narratives or analytic essays, and it is the subject matter of the research that constitutes the arts basis. Sometimes, such studies find expression in new artworks, as is the case in Merita Mita’s film made about the work of painter Ralph Hotere (Mita, 2001 ), which interlays critical analyses, documentation of process, interviews, and pulsating images of the artworks.

The third cluster involves research about teaching, therapy, or community development through one or more of the arts. Here arts are primarily the media of teaching and learning. For example, when drama is the teaching medium, the teacher may facilitate the class by taking a fictional role within the narrative that provokes students to plan, argue, or take action. Students may be prompted to use roles, create improvisations, explore body representations of ideas or conflicts, and explore contentious problems in safely fictitious contexts. Because it examines both work within an art form and changes in learners’ or community members’ understandings of other issues, this cluster overlaps somewhat with the two previous clusters. However, it is also building a body of its own traditions.

One strong tradition is the documentation of process. For example, Burton, Lepp, Morrison, and O’Toole ( 2015 ) report two decades of projects, including Dracon and Cooling Conflict , which have used drama strategies as well as formal theoretical teaching to address conflict and bullying. They have documented the specific strategies used, discussed their theoretical bases, and acknowledged the evidence on which they base their claims about effectiveness of the strategies in building understanding about and reducing bullying. The strategies used involved use of role and improvisation and what the authors call an enhanced form of Boal’s Forum Theatre. Other examples include the Risky Business Project (O’Brien & Donelan, 2008 ), a series of programs involving marginalized youth in dance, drama, music, theater performance, stand-up comedy, circus, puppetry, photography, visual arts, and creative writing; explorations of cross-cultural understandings through drama processes (Greenwood, 2005 ); the teaching of English as a second language in Malaysia through teacher-in-role and other drama processes (Mohd Nawi, 2014 ); working with traditional arts to break down culturally bound ways of seeing the world (Stanley, 2014 ); and the training of a theater-for-development team to use improvisational strategies to address community problems (Okagbue, 2002 ). While the strategies are arts processes and the analysis of their effect addresses aesthetic dimensions of arts as well as cognitive and behavioral ones, the reporting of these projects is primarily within the more traditional verbal and discursive forms of qualitative research.

Sometimes the reporting takes a more dramatic turn. Mullens and Wills ( 2016 ) report and critically analyze Re-storying Disability Through the Arts , an event that sought to create space for dialogue between students, researchers, artists, educators, and practitioners with different involvements or interests in disability arts. They begin their report by re-creating a scene within the workshop that captures some of the tensions evoked, and follow this with a critical commentary on three community-based art practices that engage in a strategy of re-storying disability. They present arts as means to “counter powerful cultural narratives that regulate the lives and bodies of disabled people” (Mullens & Wills, 2016 , p. 5). Barrett ( 2014 ) reports a project, informed by an a/r/tography methodology, which utilized the classroom teaching of the prescribed arts curriculum to allow students to explore evolving understandings of identity and community. Montages of photographs are a central component in the report, as is a series of images that illustrate Barrett’s reflections on her own role within the investigation.

Using Art to Research Social Issues: Collecting Data

Within a social science research project, art processes might be used to collect data, to carry out analysis and interpretation, or to present findings. Perhaps the most common use is to collect data. The process of photovoice (Wang & Burns, 1997 ), for example, gives participants cameras and asks them to capture images that they consider as significant elements of the topic being investigated. Graffiti might be used to prompt absentee students to discuss their perceptions of schooling. Body sculptures, freeze frames, and hot seating are examples of drama strategies that could be used to facilitate reflection and debate about cross-cultural encounters, feelings about hospitalization, experiences of domestic violence, or an array of other topics.

In each case the art produced becomes the basis for further discussion. This process is quite different from historical concepts of art therapy, where the therapist would give expert insight into what a patient’s artwork means; here it is the participants who give the explanation, perhaps independently or perhaps through dialogue with other participants and the researcher. The embodied experience of construction provides a platform and a challenge to talking in ways that are more thoughtful and more honest than through a conventionally structured verbal interview. The talk after making is important, but the art products are not merely precursors to verbal data, they are concrete points of references to which both participants and researchers can refer and can use to prompt further introspection or deconstruction. The process of making, moreover, is one that allows time for reflection and self-editing along the way and so may yield more truthful and complex answers than those that might be given instantly in an interview. Participants who are second language speakers or who lack the vocabulary or theoretical constructs to express complex feelings, reactions, or beliefs can be enabled to use physicalization to create a bridge between what they know or feel wordlessly inside them and an external expression that can be read by others.

The art tools available for such data gathering are as varied as the tools used by artists for making art. They might include drawing, collage, painting, sculpting materials or bodies, singing, orchestration, Lego construction, movement improvisation, creation of texts, photography, graffiti, role creation, and/or spatial positioning.

Art Processes as Tools for Analysis

Art processes can also be used to analyze and interpret data. Within qualitative paradigms, the processes of collecting and interpretation of data often overlap. This is also true of arts-based research. For instance, Greenwood ( 2012 ) reported on a group of experienced Bangladeshi educators who came to New Zealand to complete their Masters. While they were proficient in English, they found colloquial language challenging, struggling often to find words with the right social or emotional connotations at the speed of conversation. In previous discussions, they often looked to each other for translation. A teaching workshop, held as an illustration of arts-based research, addressed the research question: what have been your experiences as international students? A small repertoire of drama strategies, particularly freeze frames with techniques for deconstructing and refining initial offers, short animations, and narrative sequencing were used. These prompted participants to recall and show personal experiences, to critically view and interpret one another’s representations, and to further refine their images to clarify their intended meaning. The participants flung themselves into the challenge with alacrity and flamboyance and created images of eagerness, hope, new relationships, frustration, failed communication, anger, dejection, unexpected learning, and achievement. They also actively articulated ideas as we deconstructed the images and, through debate, co-constructed interpretations of what was being shown in the work and what it meant in terms of their experience, individual and shared, of overseas study. The interweaving of making, reflection, discussion, and further refinement is intrinsic to process drama; as a research method, it affords a means of interweaving data collection and collaborative analysis. In this case the participants also debated aspects of the validity of the process as research, raising questions about subjectivity in interpretation, about the nature of crystallization (Richardson, 1994 ), about informed consent, and about co-construction of narratives. Analysis shifted from being the task of an outsider researcher to one carried out, incrementally and experimentally, by insider participants. While the researcher held the initial power to focus the work, participants’ physical entry into the work, and their interrogation of the images that were created constituted a choice of how much they would share and contribute, and so they became active and sometimes playful partners in the research. This approach to analysis shares many features with participatory action research (Brydon-Miller et al., 2011 ), both in eliciting the agency of participants and in evolving a process of analysis that is interwoven with the gathering of data from preceding action and with the planning of further investigative cycles of action.

The work of Boal is perhaps one of the best known examples of the use of an art process, in this case theater, as a means of analysis of data. Boal’s Theatre of the Oppressed ( 1979 ) details a series of strategies for deconstruction and collaborative analysis. For example, in the process he calls image theatre , participants select a local oppressive problem that they seek to resolve. They create and discuss images that exemplify experience of the problem and their idealized solutions (the data); they then analyze their images to find where power resides and how it is supported. Boal’s theater process calls for experimentation with further images that explore scenarios where power could become shared to some extent and could allow further action by those who experience the oppression. The process finishes with consequential explorations of the first step to be taken by participants as a means to work toward an equilibrium of power. Boal, as the title of his book, Theatre of the Oppressed , acknowledges, draws on the work of his Braziailan compatriot, Freire, and particularly on his concept of conscientization (Freire, 1970 , 1972 ). Boal’s process for analyzing experiences of oppression is not so much a direct action plan as a means of analyzing the mechanisms of specific conditions of oppression and the potential, however limited, for agency to resolve the oppression. The sequenced strategies of creating and discussing alternative images of oppression, power relationships, and action enable participants to deconstruct the socio-cultural reality that shapes their lives and to gain awareness of their capacity to transform it.

Art as a Means to Present Findings

There is a large and growing body of research that presents findings in arts forms. A few examples are briefly discussed.

After collecting data, through interviews and official communications from participants in a case where a district school was being threatened with closure, Owen ( 2009 ) commissioned a composer to write a score for sections of his transcripts and create a community opera. He expressed the hope that this would “transform their tiny stories into noisy histories” (p. 3). Part of the data was sung at a conference I attended. I was struck by the shift in power. What I might have regarded as dull data in a PowerPoint presentation now became a compelling articulation of experiences and aspirations and a dynamic debate between personal lives and authoritarian policy.

The AIDS Memorial Quilt project (Morris, 2011 ; Yardlie & Langley, 1995 ) is frequently described as the world’s greatest piece of community folk art. A claim can be made that, while each panel in the quilt is a product of folk art, the collation of the quilt in its enormity is a work of conceptual art that juxtaposes the fragility and isolation of individual loss with the overwhelming global impact of the AIDS epidemic. The quilt can also be seen as research that visually quantifies the death toll through AIDS in Western world communities and that qualitatively investigates the life stories and values of those who died through the perceptions of those who loved them.

A number of museums throughout the world present visual and kinaesthetic accounts of social and historical research. Well-known examples are the Migration Museum in Melbourne, the Apartheid Museum in Johannesburg, and the Documentation Center for the History of National Socialism in Munich. A less securely established exhibition is that of images of the Australian Aboriginal Stolen Generation that was collected by the Dumbartung Aboriginal Corporation to educate community and schoolchildren, “but only had the funding to showcase the exhibit for one night” (Diss, 2017 ). These and many other exhibitions create visual and experiential environments where the data of history can be not only seen and read but also felt.

In a similar way to how these exhibitions use actual archival photographs, theater may use the exact words of interviews to re-tell real stories. In making Verbatim , Brandt and Harcourt ( 1994 ) collated the words from 30 interviews with convicted murderers, their families, and the families of murder victims. “We went into the prisons to find out what the story was that we were going to tell, and that was the story that emerged from the material we collected,” Harcourt explained (White, 2013 ). “Not only the content, but also the form emerged from that context. We didn’t go in having decided we were going to make a solo show. Form emerged from the experience of the prison system.”

A frequently used form is that of ethnodrama (Mienczakowski, 1995 ; Saldaña, 2008 ). Ethnodrama presents data in a theatrical form: using stage, role, and sometimes lighting and music. Saldaña ( 2008 ) explains that ethnodrama maintains “close allegiance to the lived experiences of real people while presenting their voices through an artistic medium” (p. 3) and argues that the goals are not only aesthetic, they also possess emancipatory potential for motivating social change within participants and audiences.

Sometimes the ethnographic material is further manipulated in the presentation process. Conrad ( 2012 ) describes her research into the Native program at the Alberta youth corrections center in play form as “an ethnographic re-presentation of the research—a creative expression of the research findings” (p. xii). Her play jumps through time, creating fragments of action, and is interspersed by video scenes that provide alternative endings that could result from choices made by the characters. Conrad explains her choice of medium: “Performance has the potential to reach audiences in ways beyond intellectual understanding, through engaging other ways of knowing that are empathetic, emotional, experiential, and embodied, with the potential for radically re-envisioning social relations” (p. xiii).

Belliveau ( 2015 ) created a performative research about his work in teaching Shakespeare’s Much Ado About Nothing in an elementary school. He interwove excerpts of students’ performances from the Shakespearean text with excerpts of their discussions about the issues of power, pride, love, and other themes in a new performance work that illustrated as well as explained primary students’ response to Shakespeare. He later presented a keynote at the IDEA (International Drama in Education Association) conference in Paris where he performed his discussion of this and other work with young students. Similarly, Lutton’s ( 2016 ) doctoral research explored the work and challenges of selected international drama educators using imagination and role play. In her final performance of her research, she took the role of an archivist’s assistant at a fictitious Museum of Educational Drama and Applied Theatre to provide “an opportunity for drama practitioners to use their skills and knowledge of drama pedagogy to tell their own stories” (Lutton, p. 36). She states that her choice of research tool embraces theatricality, enabling the embodiment of participants’ stories, the incorporation of critical reflection and of aesthetic knowledge (p. 36).

The Cheviot, the Stag, and the Black Black Oil , developed by John McGrath and the 7:84 Theatre Company, recounts the history of economic exploitation of the Scottish people, from the evictions that followed the clearances for the farming of Cheviot sheep, through the development of Highland stag hunts, to the capitalist domination of resources in the 1970s oil boom. Within a traditional ceilidh form it tells stories, presents arguments, and uses caricature, satire, and parody. The play is the result of research and of critical analysis of movements of power and economic interests. It is also a very effective instrument of political persuasion: McGrath gives the dispossessed crofters a language that tugs at our empathy whereas that of the landlords provokes our antagonism. Is this polemics or simple historic truth? Does the dramatic impact of the play unreasonably capture our intellects? And if the facts that are presented are validated by other accounts of history does it matter if it does? What is, what should be, what can be the relationship between research and the evocation, even manipulation of emotions?

Emotion—and Its Power

In as much as arts offer different ways of knowing the world, their use at various stages of research has the power to influence both what we come to know and how we know it. Art tools, strategically used, allow access to emotions and visceral responses as well as to conscious ideas. That makes them powerful for eliciting information. It also makes them powerful in influencing audiences.

The photos of the brutality of the police and of the steadfastness of the activists in the Apartheid Museum in Johannesburg are examples of powerfully influencing as well as informing data. As well as the events that are recorded, the faces and the bodies speak through the photos. Their exhibition in blown-up size at eye level together with film footage and artifacts create a compellingly powerful response in viewers. Like many others, I came out of the museum emotionally drained and confirmed, even strengthened, in my ideological beliefs. The power of the exhibition had first sharpened and then consolidated my understandings. Was this because of the power of the facts presented in the exhibition, or was it because of the power of their presentation ? Or was it both? When the issue presented is one like apartheid, I am not afraid of having my awareness influenced in multiple ways: I believe I already have an evidence-informed position on the subject. I also applaud the power of the exhibition to inform and convince those who might not yet have reached a position. But what if the issue was a different one? Perhaps one which I was more uncertain about? Might it then seem that the emotional power of the exhibition gave undue weight to the evidence?

The issue here is not a simple one. The presentation is not only the reporting of findings: it is also art. The researcher (in the artist) stays true to the data; the artist (in the researcher) arranges data for effect and affect. Conrad explicitly states her hope that her choice of presentation mode will add impact to her research findings: she wants the presentation of her research about youth in detention centers to engender more empathetic understandings of their experiences and lead, in turn, to more constructive attitudes toward their needs. By putting their words to music, Owen wants his audience to listen more attentively to opinions of the stakeholders in the schools threatened with closure. McGrath wants his audience to side with those dispossessed by the combined power of capital and law. The Dumbartung Aboriginal Corporation plans to emotionally move as well as to inform its community. In writing Broadwood , I meticulously presented both sides of the dispute, I deliberately placed music and metaphor at the service of Maori language, and I deliberately used the spatial suggestiveness of the stage to evoke possibilities in the ending. The boy is alone in the library while his classmates are on the marae listening to an elder explain the history of their meetinghouse. The elder gives them an ancient whalebone weapon to hold, the students pass it among themselves, then hold it out across space to the boy. The boy stands, takes half a cautious step toward them and then stops; the lights go down. I intended the audience to complete the action in their subconscious.

In each of these cases, the art form of the presentation allows the artist/researcher to manipulate affect as well as critical cognition. To my mind, this is not simply another iteration of the argument between subjectivity and objectivity in research. Many contemporary approaches to research openly recognize that knowledge is mediated by context, experience, and social and historical discourses as well as by individuals’ personal interpretation (Denzin & Lincoln, 2011 ; Ellis, 2004 ). It is shaped by what is left out as well as by what is included. The practice of careful and scrupulous reflexivity is a way of acknowledging and bounding the subjectivity of the researcher (Altheide & Johnson, 2011 ; Ellingson, 2011 ). The researcher-who-is-artist draws on a subconscious as well as a conscious sense of how things fit together, and constructs meaning subconsciously as well as consciously, manipulating affect and effect in the process. Perhaps all researchers do so to some extent. For instance, the deliberately invisible authors of much quantitative research, who allow the passive voice to carry much of the reporting, who triangulate and define limitation, create an effect of fair-minded and dependable authority. The affect is not necessarily misleading, and it is something that readers of research have learned to recognize. However, the researcher-who-is-artist can draw on the rich repertoire of an art field that already operates in the domain of the aesthetic as well as of the critically cognitive, in spaces that are liminal as well those that are defined. It is arguable that readers of research still need to recognize and navigate through those spaces. Arguably, the challenge exists not only in the field of research: it is present in all the media that surrounds our daily lives.

A/r/tography and Examination of Places Between

The challenge of exploring liminal spaces of intention, process, explanation, effect, and affect is seriously taken up by the emergent discipline of a/r/tography . The backslashes in the term speak of fracture; they also denote the combined authorial roles of artist, researcher, and teacher. Springgay, Irwin, and Kind ( 2005 ) explain that a/r/tography is deliberately introspective and does not seek conclusions: rather it plays with connections between art and text and seeks to capture the embodied experience of exploring self and the world. Irwin et al. ( 2006 ) state: “Together, the arts and education complement, resist, and echo one another through rhizomatic relations of living inquiry” (p. 70). A/r/tography is explicitly positioned as a practice-based and living inquiry: it explores but resists attempting to define the spaces between artist, teacher, and researcher, and so implicitly rejects boundaries between these roles. It conceptualizes inquiry as a continuing experiential process of encounter between ideas, art media, context, meaning, and evolving representations. At the same time as it blurs distinctions, it teases out interrelationships: it offers art inquiry as something that is purposeful but unfixed, and art knowing as something that is personally and socially useful, but at best only partially and temporarily describable, never definable. This is one reason why its proponents explain it as a substantively different and new methodology outside the existing frameworks of qualitative research.

A/r/tography emerged out of the field of art education, with the explicit aim to extend the opportunities afforded by education in the arts, and to develop means to record and report the complex facets of learning and teaching in the arts. Consequently its language may be experienced, by readers who are outside the discipline, as highly abstract, deliberately ambiguous, and even esoteric: it seems to speak, as many research disciplines do, primarily to others in its own field. However, its broad principles have been picked up, and perhaps adapted, by practitioners who seek to explore the processes of their students’ learning through the arts and the evolving understandings they develop. For instance, Barrett and Greenwood ( 2013 ) report exploration of the epistemological third space through which place-conscious education and visual arts pedagogy can be interwoven and through which students, many of whom do not aspire to become artists, can use art-making to re-imagine and re-mark their understandings of their physical and social context and of their relationship with community. The value of this kind of research is posed in terms of the insights it affords rather than its capacity for presenting authoritative conclusions.

A Conference Debate, and the Politics of Research

Whether the provision of insights is enough to make art-making into research is a question that is frequently and sometimes fiercely contested. One such debate took place at a European conference I recently attended. It occurred in an arts-based research stream, and it began with the presentation of two films. The films were relatively short, and a discussion followed and became increasingly heated. Personally, I liked the films. The first reported a dance process that became an undergraduate teaching text. The second, in layers of imagery and fragments of dialogue, explored the practice of two artists. However, I was not sure what the added value was in calling either research. I saw art responding to art, and that seemed valuable and interesting enough. Why was the construct of research being privileged? The filmmakers defended the claim to research on the grounds that there was inquiry, on the grounds that art spoke in languages that were best discussed through art, and on the grounds that research was privileged in their institutions. Then a respected professor of fine arts put forward more direct criticism. Research, he argued, needed to make explicit the decisions that were made in identifying and reporting findings so that these would be accessible for peer review. Neither film, he said, did so. Defenses from the audience were heated. Then another senior art educator argued that art itself could not just be self-referential: it had to open a space for others to enter. The debate continued in corridors long after the session ended.

That the criticisms were unrelenting seemed an indication of how much was at stake. The space held by arts-based research within the European academic congregation is still somewhat fragile. The arts-based network was formed because of advocates’ passionate belief in the extended possibilities that arts-based methods offer, and this year again it expressed its eagerness to receive contributions in film and other art media as well as PowerPoint and verbal presentations. However, the network also saw itself as a custodian of rigor.

The participants in the session re-performed an argument that lingers at the edges of arts-based research. At the far ends of the spectrum, art and research are readily recognizable, and when art is borrowed as a tool in research, the epistemological and methodological assumptions are explicable. But the ground is more slippery when art and research intersect more deeply. When is the inquiry embedded within art, and when does it become research? Is it useful to attempt demarcations? What is lost from art or from research if demarcations are not attempted? The questions, as well as possible answers, are, as Eisner suggested, political as well as philosophical and methodological.

The doing of research and its publication have become big academic business. Universities around the world are required to report their academics’ research outputs to gain funding. My university, for example, is subject to a six-yearly round of assessment of research performance, based primarily on published and on funded research outputs. Each academic’s outputs are categorized and ranked, and the university itself is ranked and funded, in comparison with the other universities in the country. There is pressure on each academic to maximize research publications, even at the cost, it often seems, of other important academic activities, such as teaching. The competitive means of ranking also increases contestations about what is real research, serving both as a stimulus for positioning differing forms of inquiry as research and as a guarded gateway that permits some entries and denies others. Politicians and policymakers, in their turn, favor and fund research that can provide them with quotable numbers or clear-cut conclusions. Arts-based research still battles for a place within this politico-academic ground, although there appears to be growing acceptance of the use of art tools as means to elicit data.

Site for Possibilities—and Questions

The politics of research do matter, but for researchers who are committed to doing useful research, there are other factors to consider when choosing research approaches. These include the potentialities of the tools, the matter that is to be investigated, and the skills and practice preferences of the researcher.

The emergence and development of processes of arts-based research are grounded in belief that there are many ways of knowing oneself and the world, and these include emotions and intuitive perceptions as well as intellectual cognition. The epistemology of arts-based research is based on understandings that color, space, sound, movement, facial expression, vocal tone, and metaphor are as important in expressing and understanding knowledge as the lexical meanings of words. It is based on understandings that symbols, signs, and patterns are powerful means of communication, and that they are culturally and contextually shaped and interpreted. Arts-based research processes tolerate, even sometimes celebrate, ambiguity and ambivalence. They may also afford license to manipulate emotions to evoke empathy or direct social action.

The use of arts-based processes for eliciting participants’ responses considerably increases researchers’ repertoire for engaging participants and for providing them with means of expression that allow them to access feelings and perceptions that they might not initially be able to put into words as well as giving them time and strategies for considering their responses. The use of arts-based processes for analysis and representation allow opportunities for multidimensional, sensory, and often communal explorations of the meaning of what has been researched. It also presents new challenges to receivers of research who need to navigate their way not only through the overt ambiguities and subjective expression, but also through the invisible layers of affect that are embedded in art processes.

The challenges signal continuing areas of discussion, and perhaps work, for both arts-based researchers and for the wider research community. Does the use of art in representation of research findings move beyond the scope of critical peer review? Or do we rather need to develop new languages and strategies for such review? Do we need critical and recursive debate about when art becomes research and when it does not? Are the ambiguities and cognitive persuasions that are inherent in arts-based representations simply other, and useful, epistemological stances? Does the concept of research lose its meaning if it is stretched too far? Does art, which already has a useful role in interpreting and even shaping society, need to carve out its position as research? Does the entry of arts-based research into the arena of research call for revisions to the way we consider ethics? How do the procedures of institutional ethics committees need to be adapted to accommodate the engagement of the human body as well as the emergent design and ambiguities of the arts-based research processes? What are the more complex responsibilities of arts-based researchers toward their participants, particularly in terms of cultural protocols, reciprocity of gains, and the manipulation of emotions and cognition through visually or dramatically powerful presentations?

The already existing and expanding contribution of arts-based researchers argues vigorously for the place of arts processes in our congregations of research discussion and production. Quite simply, the arts address aspects of being human that are not sufficiently addressed by other methodologies. They are needed in our repertoire of tools for understanding people and the world. However, like other research approaches, they bring new challenges that need to be recognized and debated.

Types of Research Design

Types of Research

Research is about using established methods to investigate a problem or question in detail with the aim of generating new knowledge about it.

It is a vital tool for scientific advancement because it allows researchers to prove or refute hypotheses based on clearly defined parameters, environments and assumptions. Due to this, it enables us to confidently contribute to knowledge as it allows research to be verified and replicated.

Knowing the types of research and what each of them focuses on will allow you to better plan your project, utilises the most appropriate methodologies and techniques and better communicate your findings to other researchers and supervisors.

Classification of Types of Research

There are various types of research that are classified according to their objective, depth of study, analysed data, time required to study the phenomenon and other factors. It’s important to note that a research project will not be limited to one type of research, but will likely use several.

According to its Purpose

Theoretical research.

Theoretical research, also referred to as pure or basic research, focuses on generating knowledge , regardless of its practical application. Here, data collection is used to generate new general concepts for a better understanding of a particular field or to answer a theoretical research question.

Results of this kind are usually oriented towards the formulation of theories and are usually based on documentary analysis, the development of mathematical formulas and the reflection of high-level researchers.

Applied Research

Here, the goal is to find strategies that can be used to address a specific research problem. Applied research draws on theory to generate practical scientific knowledge, and its use is very common in STEM fields such as engineering, computer science and medicine.

This type of research is subdivided into two types:

  • Technological applied research : looks towards improving efficiency in a particular productive sector through the improvement of processes or machinery related to said productive processes.
  • Scientific applied research : has predictive purposes. Through this type of research design, we can measure certain variables to predict behaviours useful to the goods and services sector, such as consumption patterns and viability of commercial projects.

Methodology Research

According to your Depth of Scope

Exploratory research.

Exploratory research is used for the preliminary investigation of a subject that is not yet well understood or sufficiently researched. It serves to establish a frame of reference and a hypothesis from which an in-depth study can be developed that will enable conclusive results to be generated.

Because exploratory research is based on the study of little-studied phenomena, it relies less on theory and more on the collection of data to identify patterns that explain these phenomena.

Descriptive Research

The primary objective of descriptive research is to define the characteristics of a particular phenomenon without necessarily investigating the causes that produce it.

In this type of research, the researcher must take particular care not to intervene in the observed object or phenomenon, as its behaviour may change if an external factor is involved.

Explanatory Research

Explanatory research is the most common type of research method and is responsible for establishing cause-and-effect relationships that allow generalisations to be extended to similar realities. It is closely related to descriptive research, although it provides additional information about the observed object and its interactions with the environment.

Correlational Research

The purpose of this type of scientific research is to identify the relationship between two or more variables. A correlational study aims to determine whether a variable changes, how much the other elements of the observed system change.

According to the Type of Data Used

Qualitative research.

Qualitative methods are often used in the social sciences to collect, compare and interpret information, has a linguistic-semiotic basis and is used in techniques such as discourse analysis, interviews, surveys, records and participant observations.

In order to use statistical methods to validate their results, the observations collected must be evaluated numerically. Qualitative research, however, tends to be subjective, since not all data can be fully controlled. Therefore, this type of research design is better suited to extracting meaning from an event or phenomenon (the ‘why’) than its cause (the ‘how’).

Quantitative Research

Quantitative research study delves into a phenomena through quantitative data collection and using mathematical, statistical and computer-aided tools to measure them . This allows generalised conclusions to be projected over time.

Types of Research Methodology

According to the Degree of Manipulation of Variables

Experimental research.

It is about designing or replicating a phenomenon whose variables are manipulated under strictly controlled conditions in order to identify or discover its effect on another independent variable or object. The phenomenon to be studied is measured through study and control groups, and according to the guidelines of the scientific method.

Non-Experimental Research

Also known as an observational study, it focuses on the analysis of a phenomenon in its natural context. As such, the researcher does not intervene directly, but limits their involvement to measuring the variables required for the study. Due to its observational nature, it is often used in descriptive research.

Quasi-Experimental Research

It controls only some variables of the phenomenon under investigation and is therefore not entirely experimental. In this case, the study and the focus group cannot be randomly selected, but are chosen from existing groups or populations . This is to ensure the collected data is relevant and that the knowledge, perspectives and opinions of the population can be incorporated into the study.

According to the Type of Inference

Deductive investigation.

In this type of research, reality is explained by general laws that point to certain conclusions; conclusions are expected to be part of the premise of the research problem and considered correct if the premise is valid and the inductive method is applied correctly.

Inductive Research

In this type of research, knowledge is generated from an observation to achieve a generalisation. It is based on the collection of specific data to develop new theories.

Hypothetical-Deductive Investigation

It is based on observing reality to make a hypothesis, then use deduction to obtain a conclusion and finally verify or reject it through experience.

Descriptive Research Design

According to the Time in Which it is Carried Out

Longitudinal study (also referred to as diachronic research).

It is the monitoring of the same event, individual or group over a defined period of time. It aims to track changes in a number of variables and see how they evolve over time. It is often used in medical, psychological and social areas .

Cross-Sectional Study (also referred to as Synchronous Research)

Cross-sectional research design is used to observe phenomena, an individual or a group of research subjects at a given time.

According to The Sources of Information

Primary research.

This fundamental research type is defined by the fact that the data is collected directly from the source, that is, it consists of primary, first-hand information.

Secondary research

Unlike primary research, secondary research is developed with information from secondary sources, which are generally based on scientific literature and other documents compiled by another researcher.

Action Research Methods

According to How the Data is Obtained

Documentary (cabinet).

Documentary research, or secondary sources, is based on a systematic review of existing sources of information on a particular subject. This type of scientific research is commonly used when undertaking literature reviews or producing a case study.

Field research study involves the direct collection of information at the location where the observed phenomenon occurs.

From Laboratory

Laboratory research is carried out in a controlled environment in order to isolate a dependent variable and establish its relationship with other variables through scientific methods.

Mixed-Method: Documentary, Field and/or Laboratory

Mixed research methodologies combine results from both secondary (documentary) sources and primary sources through field or laboratory research.

Huawei has been secretly funding research in America after being blacklisted

The money’s being funneled through a washington-based foundation and a university competition..

Chinese tech giant Huawei has been secretly funding research in America despite being blacklisted, as reported by Bloomberg . The cutting-edge research is happening at universities, including Harvard, and the money is being funneled through an independent Washington-based research foundation, along with a competition for scientists.

Bloomberg found that Huawei was the sole funder of a research competition that has awarded millions of dollars since 2022 and attracted hundreds of proposals from scientists. Some of these scientists are at top US universities that have banned researchers from working with the company.

What’s the big deal? The fear is that this research could lead to innovations that give China a leg up with regard to both defense contracting and commercial interests, according to Kevin Wolf, a partner at the business-focused law firm Akin who specializes in export controls. Optica, the foundation behind all of this, has posted online that it is interested in “high-sensitivity optical sensors and detectors," among other categories of research.

“It’s a bad look for a prestigious research foundation to be anonymously accepting money from a Chinese company that raises so many national security concerns for the US government,” said James Mulvenon, a defense contractor who has worked on research security issues and co-authored several books on industrial espionage.

It’s worth noting that this money funneling operation doesn’t look to be illegal, as research intended for publication doesn’t fall under the purview of the ban. Huawei operates similar competitions in other parts of the world, though openly. People who participated in the US-based research competition didn’t even know that Huawei was involved, believing the money to come from Optica. The competition awards $1 million per year and Optica didn’t give any indication that Huawei was supplying the cash.

A Huawei spokesperson told Bloomberg that the company and the Optica Foundation created the competition to support global research and promote academic communication, saying that it remained anonymous to keep from being seen as a promotion of some kind. Optica’s CEO, Liz Rogan, said in a statement that many foundation donors “prefer to remain anonymous” and that “there is nothing unusual about this practice.” She also said that the entire board knew about Huawei’s involvement and that everyone signed off on it. Bloomberg did note that the Huawei-backed competition was the only one on Optica’s website that didn’t list individual and corporate financial sponsors.

Huawei has been wrapped in a web of US restrictions these past several years. We can’t buy the vast majority of Huawei products in America , as the company’s been effectively banned. This all started in 2019 when President Trump signed an executive order that banned the sale and use of telecom equipment that posed “unacceptable" risks to national security. At the time, Trump said that “foreign adversaries” were exploiting security holes that would eventually lead to "potentially catastrophic effects.” Wait, Trump used the words “potentially catastrophic effects?” Wild.

To that end, the company has faced numerous claims that it installs backdoors in networks for the purpose of data theft, though there’s no proof of actual theft and the company denies the accusations. Huawei has also been accused of employing Chinese spies to influence an investigation and documents seem to indicate Huawei’s involvement in China’s surveillance efforts .

Some expected President Biden to reverse Trump’s executive order when it expired in 2021 , but he headed in the opposite direction. Not only does the order stand, but Biden signed a law that blocked Huawei from obtaining an FCC license and he banned American investments in China’s high tech industries. We aren’t cozying up to China anytime soon, so Huawei will continue to be persona non grata on this side of the pond (the company still does booming business in Europe.)

Microsoft taps Sanctuary AI for general-purpose robot research

based research purpose

Microsoft, it seems, is hedging its bets when it comes to general-purpose robotics AI. At the end of February, the Windows maker spearheaded a massive $675 million Series B in Bay Area-based Figure. Today, the tech giant announced a collaboration with Figure competitor Sanctuary AI, best known for its humanoid robot, Phoenix.

The Sanctuary partnership really gets to the heart of Microsoft’s interest in the category: artificial general intelligence. It’s a concept that comes up a lot when discussing humanoid robots — too often, I would argue, given the state of things. While such breakthroughs are likely several years off (at least), they’re required for humanoid robots to reach the long promised “general-purpose status.”

In essence, that means robots that can learn and reason like humans. That represents a potential quantum leap for robotic capabilities, which have traditionally been limited to one or two tasks. The humanoid form factor opens these systems to a far broader range of motion than single-purpose systems, but they will ultimately need the intelligence to match.

“Creating systems that think like, and understand us, is one of the biggest civilization-level technical problems and opportunities that we will ever face,” Sanctuary co-founder and CEO Geordie Rose notes. “A challenge like this requires the best global minds to work together. We’re excited to be working with Microsoft to unlock the next generation of AI models that will power general-purpose robots.”

Such a partnership deepens Microsoft’s commitment to AI development and delivers a partner who can design hardware to those specifications. Sanctuary has been operating in the space for some time now, and recently scored a pilot partnership with Magna , which will bring the latest version of Phoenix to car plants.

All told, Sanctuary robots “have been tested across 400 customer-defined tasks across 15 different industries.” Of course, we’re still in the very early stages of all of this.

Microsoft founder Bill Gates spoke about his own interest in humanoids earlier this year. Neither Sanctuary nor Figure got a mention, though he did spend some time discussing competitors Agility and Apptronik.

Microsoft isn’t alone in hedging its bets in the category. OpenAI (another Microsoft partner) has made its own investments in both Figure and competitor 1X.

Postdoctoral Fellow - endocrine, cancer research

Job description.

Come join our friendly, collaborative group and help us improve treatments for patients with endocrine cancers!

A Postdoctoral position is available beginning in mid-to-late summer in the Surgical Oncology Program, CCR, NCI. Our group, the Laboratory of Neuro-Endocrine Cancer Diagnostics and Therapy is seeking a motivated Postdoctoral fellow interested in working at the interface of the application of novel therapeutic development and primary model development. Our laboratory program is dedicated to studying the behavior and growth of aggressive endocrine cancer and identifying novel and effective targeted therapies for personalized treatment of metastatic endocrine cancers.

Applicants will gain experience in protein signaling, cancer cell genome modification, single-cell cancer genomics, cell and molecular assays, and preclinical drug development. One particular group of endocrine cancers, gastroenteropancreatic neuroendocrine tumors (GEP-NETs), have limited models available despite an increasing public health burden. These models are limited to only the most aggressive cancer phenotypes, which limits our ability to treat tumors early enough to provide benefit to patients. New models can be derived from patient tissues, and our early work has shown promise in the development of several new study systems including cell lines, organoids, and patient derived xenografts. Some of our current therapeutic work has involved SSTR2 expression modification using epigenetic modifying therapeutics. By changing the expression of SSTR2, the opportunity to treat patients with more aggressive cancers is improved, providing a safer and more effective alternative to toxic chemotherapy regimens. We are currently using advanced analyses including cell line therapeutic sensitivity screening, bioinformatic based single-cell “multiomic” interrogation, functional genomic CRISPR inhibition and activation screens and genetic modeling of primary tumors to further explore new therapeutic targets. Fellows would be exposed to all areas of current research in the lab and multiple projects and techniques would be available to explore.

Endocrine Oncology at NIH encompasses unique patient cohorts of rare endocrine cancers, and our multi-disciplinary program has the capacity to translate preclinical findings into clinical trials, with the purpose of improving patient outcomes.

Training opportunities are augmented by collaborations with colleagues and physicians from the intramural and extramural communities. Fellows are encouraged to take advantage of formal, focused courses (e.g., training in bioinformatics and translational research), actively engage and participate in a variety of activities such as journal clubs within the Surgical Oncology Branch.  

Qualifications and Job Details

Required and preferred skills.

  • Candidates must have a PhD and/or MD degree or equivalent that includes training in molecular biology, cell biology, bioinformatics, or biochemistry, with laboratory experience.
  • Strong background in genetics/genomics, bioinformatic analysis, tissue culture, and molecular biological techniques (e.g., cloning, western blot, qPCR, protein expression/purification). 
  • Excellent written and verbal communication, organizational, and time management skills are preferred, and with an ability to work independently as well as collaborate as a valued team member.  

This position is subject to a background investigation.  

  • Some experience with R or another coding language preferred, but not required.
