dissertation course objectives

• Aims and Objectives – A Guide for Academic Writing
• Doing a PhD

One of the most important aspects of a thesis, dissertation or research paper is the correct formulation of the aims and objectives. This is because your aims and objectives will establish the scope, depth and direction that your research will ultimately take. An effective set of aims and objectives will give your research focus and your reader clarity, with your aims indicating what is to be achieved, and your objectives indicating how it will be achieved.

Introduction

There is no getting away from the importance of the aims and objectives in determining the success of your research project. Unfortunately, however, it is an aspect that many students struggle with, and ultimately end up doing poorly. Given their importance, if you suspect that there is even the smallest possibility that you belong to this group of students, we strongly recommend you read this page in full.

This page describes what research aims and objectives are, how they differ from each other, how to write them correctly, and the common mistakes students make and how to avoid them. An example of a good aim and objectives from a past thesis has also been deconstructed to help your understanding.

What Are Aims and Objectives?

Research aims.

A research aim describes the main goal or the overarching purpose of your research project.

In doing so, it acts as a focal point for your research and provides your readers with clarity as to what your study is all about. Because of this, research aims are almost always located within its own subsection under the introduction section of a research document, regardless of whether it’s a thesis , a dissertation, or a research paper .

A research aim is usually formulated as a broad statement of the main goal of the research and can range in length from a single sentence to a short paragraph. Although the exact format may vary according to preference, they should all describe why your research is needed (i.e. the context), what it sets out to accomplish (the actual aim) and, briefly, how it intends to accomplish it (overview of your objectives).

To give an example, we have extracted the following research aim from a real PhD thesis:

Example of a Research Aim

The role of diametrical cup deformation as a factor to unsatisfactory implant performance has not been widely reported. The aim of this thesis was to gain an understanding of the diametrical deformation behaviour of acetabular cups and shells following impaction into the reamed acetabulum. The influence of a range of factors on deformation was investigated to ascertain if cup and shell deformation may be high enough to potentially contribute to early failure and high wear rates in metal-on-metal implants.

Note: Extracted with permission from thesis titled “T he Impact And Deformation Of Press-Fit Metal Acetabular Components ” produced by Dr H Hothi of previously Queen Mary University of London.

Research Objectives

Where a research aim specifies what your study will answer, research objectives specify how your study will answer it.

They divide your research aim into several smaller parts, each of which represents a key section of your research project. As a result, almost all research objectives take the form of a numbered list, with each item usually receiving its own chapter in a dissertation or thesis.

Following the example of the research aim shared above, here are it’s real research objectives as an example:

Example of a Research Objective

• Develop finite element models using explicit dynamics to mimic mallet blows during cup/shell insertion, initially using simplified experimentally validated foam models to represent the acetabulum.
• Investigate the number, velocity and position of impacts needed to insert a cup.
• Determine the relationship between the size of interference between the cup and cavity and deformation for different cup types.
• Investigate the influence of non-uniform cup support and varying the orientation of the component in the cavity on deformation.
• Examine the influence of errors during reaming of the acetabulum which introduce ovality to the cavity.
• Determine the relationship between changes in the geometry of the component and deformation for different cup designs.
• Develop three dimensional pelvis models with non-uniform bone material properties from a range of patients with varying bone quality.
• Use the key parameters that influence deformation, as identified in the foam models to determine the range of deformations that may occur clinically using the anatomic models and if these deformations are clinically significant.

It’s worth noting that researchers sometimes use research questions instead of research objectives, or in other cases both. From a high-level perspective, research questions and research objectives make the same statements, but just in different formats.

Taking the first three research objectives as an example, they can be restructured into research questions as follows:

Restructuring Research Objectives as Research Questions

• Can finite element models using simplified experimentally validated foam models to represent the acetabulum together with explicit dynamics be used to mimic mallet blows during cup/shell insertion?
• What is the number, velocity and position of impacts needed to insert a cup?
• What is the relationship between the size of interference between the cup and cavity and deformation for different cup types?

Difference Between Aims and Objectives

Hopefully the above explanations make clear the differences between aims and objectives, but to clarify:

• The research aim focus on what the research project is intended to achieve; research objectives focus on how the aim will be achieved.
• Research aims are relatively broad; research objectives are specific.
• Research aims focus on a project’s long-term outcomes; research objectives focus on its immediate, short-term outcomes.
• A research aim can be written in a single sentence or short paragraph; research objectives should be written as a numbered list.

How to Write Aims and Objectives

Before we discuss how to write a clear set of research aims and objectives, we should make it clear that there is no single way they must be written. Each researcher will approach their aims and objectives slightly differently, and often your supervisor will influence the formulation of yours on the basis of their own preferences.

Regardless, there are some basic principles that you should observe for good practice; these principles are described below.

Your aim should be made up of three parts that answer the below questions:

• Why is this research required?
• What is this research about?
• How are you going to do it?

The easiest way to achieve this would be to address each question in its own sentence, although it does not matter whether you combine them or write multiple sentences for each, the key is to address each one.

The first question, why , provides context to your research project, the second question, what , describes the aim of your research, and the last question, how , acts as an introduction to your objectives which will immediately follow.

Scroll through the image set below to see the ‘why, what and how’ associated with our research aim example.

Note: Your research aims need not be limited to one. Some individuals per to define one broad ‘overarching aim’ of a project and then adopt two or three specific research aims for their thesis or dissertation. Remember, however, that in order for your assessors to consider your research project complete, you will need to prove you have fulfilled all of the aims you set out to achieve. Therefore, while having more than one research aim is not necessarily disadvantageous, consider whether a single overarching one will do.

Research Objectives

Each of your research objectives should be SMART :

• Specific – is there any ambiguity in the action you are going to undertake, or is it focused and well-defined?
• Measurable – how will you measure progress and determine when you have achieved the action?
• Achievable – do you have the support, resources and facilities required to carry out the action?
• Relevant – is the action essential to the achievement of your research aim?
• Timebound – can you realistically complete the action in the available time alongside your other research tasks?

In addition to being SMART, your research objectives should start with a verb that helps communicate your intent. Common research verbs include:

Table of Research Verbs to Use in Aims and Objectives

Last, format your objectives into a numbered list. This is because when you write your thesis or dissertation, you will at times need to make reference to a specific research objective; structuring your research objectives in a numbered list will provide a clear way of doing this.

To bring all this together, let’s compare the first research objective in the previous example with the above guidance:

Checking Research Objective Example Against Recommended Approach

Research Objective:

1. Develop finite element models using explicit dynamics to mimic mallet blows during cup/shell insertion, initially using simplified experimentally validated foam models to represent the acetabulum.

Checking Against Recommended Approach:

Q: Is it specific? A: Yes, it is clear what the student intends to do (produce a finite element model), why they intend to do it (mimic cup/shell blows) and their parameters have been well-defined ( using simplified experimentally validated foam models to represent the acetabulum ).

Q: Is it measurable? A: Yes, it is clear that the research objective will be achieved once the finite element model is complete.

Q: Is it achievable? A: Yes, provided the student has access to a computer lab, modelling software and laboratory data.

Q: Is it relevant? A: Yes, mimicking impacts to a cup/shell is fundamental to the overall aim of understanding how they deform when impacted upon.

Q: Is it timebound? A: Yes, it is possible to create a limited-scope finite element model in a relatively short time, especially if you already have experience in modelling.

Q: Does it start with a verb? A: Yes, it starts with ‘develop’, which makes the intent of the objective immediately clear.

Q: Is it a numbered list? A: Yes, it is the first research objective in a list of eight.

Mistakes in Writing Research Aims and Objectives

1. making your research aim too broad.

Having a research aim too broad becomes very difficult to achieve. Normally, this occurs when a student develops their research aim before they have a good understanding of what they want to research. Remember that at the end of your project and during your viva defence , you will have to prove that you have achieved your research aims; if they are too broad, this will be an almost impossible task. In the early stages of your research project, your priority should be to narrow your study to a specific area. A good way to do this is to take the time to study existing literature, question their current approaches, findings and limitations, and consider whether there are any recurring gaps that could be investigated .

Note: Achieving a set of aims does not necessarily mean proving or disproving a theory or hypothesis, even if your research aim was to, but having done enough work to provide a useful and original insight into the principles that underlie your research aim.

2. Making Your Research Objectives Too Ambitious

Be realistic about what you can achieve in the time you have available. It is natural to want to set ambitious research objectives that require sophisticated data collection and analysis, but only completing this with six months before the end of your PhD registration period is not a worthwhile trade-off.

3. Formulating Repetitive Research Objectives

Each research objective should have its own purpose and distinct measurable outcome. To this effect, a common mistake is to form research objectives which have large amounts of overlap. This makes it difficult to determine when an objective is truly complete, and also presents challenges in estimating the duration of objectives when creating your project timeline. It also makes it difficult to structure your thesis into unique chapters, making it more challenging for you to write and for your audience to read.

Fortunately, this oversight can be easily avoided by using SMART objectives.

Hopefully, you now have a good idea of how to create an effective set of aims and objectives for your research project, whether it be a thesis, dissertation or research paper. While it may be tempting to dive directly into your research, spending time on getting your aims and objectives right will give your research clear direction. This won’t only reduce the likelihood of problems arising later down the line, but will also lead to a more thorough and coherent research project.

Dissertation Strategies

What this handout is about.

This handout suggests strategies for developing healthy writing habits during your dissertation journey. These habits can help you maintain your writing momentum, overcome anxiety and procrastination, and foster wellbeing during one of the most challenging times in graduate school.

Tackling a giant project

Because dissertations are, of course, big projects, it’s no surprise that planning, writing, and revising one can pose some challenges! It can help to think of your dissertation as an expanded version of a long essay: at the end of the day, it is simply another piece of writing. You’ve written your way this far into your degree, so you’ve got the skills! You’ll develop a great deal of expertise on your topic, but you may still be a novice with this genre and writing at this length. Remember to give yourself some grace throughout the project. As you begin, it’s helpful to consider two overarching strategies throughout the process.

First, take stock of how you learn and your own writing processes. What strategies have worked and have not worked for you? Why? What kind of learner and writer are you? Capitalize on what’s working and experiment with new strategies when something’s not working. Keep in mind that trying out new strategies can take some trial-and-error, and it’s okay if a new strategy that you try doesn’t work for you. Consider why it may not have been the best for you, and use that reflection to consider other strategies that might be helpful to you.

Second, break the project into manageable chunks. At every stage of the process, try to identify specific tasks, set small, feasible goals, and have clear, concrete strategies for achieving each goal. Small victories can help you establish and maintain the momentum you need to keep yourself going.

Below, we discuss some possible strategies to keep you moving forward in the dissertation process.

Pre-dissertation planning strategies

Get familiar with the Graduate School’s Thesis and Dissertation Resources .

Create a template that’s properly formatted. The Grad School offers workshops on formatting in Word for PC and formatting in Word for Mac . There are online templates for LaTeX users, but if you use a template, save your work where you can recover it if the template has corrruption issues.

Learn how to use a citation-manager and a synthesis matrix to keep track of all of your source information.

Skim other dissertations from your department, program, and advisor. Enlist the help of a librarian or ask your advisor for a list of recent graduates whose work you can look up. Seeing what other people have done to earn their PhD can make the project much less abstract and daunting. A concrete sense of expectations will help you envision and plan. When you know what you’ll be doing, try to find a dissertation from your department that is similar enough that you can use it as a reference model when you run into concerns about formatting, structure, level of detail, etc.

Think carefully about your committee . Ideally, you’ll be able to select a group of people who work well with you and with each other. Consult with your advisor about who might be good collaborators for your project and who might not be the best fit. Consider what classes you’ve taken and how you “vibe” with those professors or those you’ve met outside of class. Try to learn what you can about how they’ve worked with other students. Ask about feedback style, turnaround time, level of involvement, etc., and imagine how that would work for you.

Sketch out a sensible drafting order for your project. Be open to writing chapters in “the wrong order” if it makes sense to start somewhere other than the beginning. You could begin with the section that seems easiest for you to write to gain momentum.

Design a productivity alliance with your advisor . Talk with them about potential projects and a reasonable timeline. Discuss how you’ll work together to keep your work moving forward. You might discuss having a standing meeting to discuss ideas or drafts or issues (bi-weekly? monthly?), your advisor’s preferences for drafts (rough? polished?), your preferences for what you’d like feedback on (early or late drafts?), reasonable turnaround time for feedback (a week? two?), and anything else you can think of to enter the collaboration mindfully.

Design a productivity alliance with your colleagues . Dissertation writing can be lonely, but writing with friends, meeting for updates over your beverage of choice, and scheduling non-working social times can help you maintain healthy energy. See our tips on accountability strategies for ideas to support each other.

Productivity strategies

Write when you’re most productive. When do you have the most energy? Focus? Creativity? When are you most able to concentrate, either because of your body rhythms or because there are fewer demands on your time? Once you determine the hours that are most productive for you (you may need to experiment at first), try to schedule those hours for dissertation work. See the collection of time management tools and planning calendars on the Learning Center’s Tips & Tools page to help you think through the possibilities. If at all possible, plan your work schedule, errands and chores so that you reserve your productive hours for the dissertation.

Put your writing time firmly on your calendar . Guard your writing time diligently. You’ll probably be invited to do other things during your productive writing times, but do your absolute best to say no and to offer alternatives. No one would hold it against you if you said no because you’re teaching a class at that time—and you wouldn’t feel guilty about saying no. Cultivating the same hard, guilt-free boundaries around your writing time will allow you preserve the time you need to get this thing done!

Develop habits that foster balance . You’ll have to work very hard to get this dissertation finished, but you can do that without sacrificing your physical, mental, and emotional wellbeing. Think about how you can structure your work hours most efficiently so that you have time for a healthy non-work life. It can be something as small as limiting the time you spend chatting with fellow students to a few minutes instead of treating the office or lab as a space for extensive socializing. Also see above for protecting your time.

Write in spaces where you can be productive. Figure out where you work well and plan to be there during your dissertation work hours. Do you get more done on campus or at home? Do you prefer quiet and solitude, like in a library carrel? Do you prefer the buzz of background noise, like in a coffee shop? Are you aware of the UNC Libraries’ list of places to study ? If you get “stuck,” don’t be afraid to try a change of scenery. The variety may be just enough to get your brain going again.

Work where you feel comfortable . Wherever you work, make sure you have whatever lighting, furniture, and accessories you need to keep your posture and health in good order. The University Health and Safety office offers guidelines for healthy computer work . You’re more likely to spend time working in a space that doesn’t physically hurt you. Also consider how you could make your work space as inviting as possible. Some people find that it helps to have pictures of family and friends on their desk—sort of a silent “cheering section.” Some people work well with neutral colors around them, and others prefer bright colors that perk up the space. Some people like to put inspirational quotations in their workspace or encouraging notes from friends and family. You might try reconfiguring your work space to find a décor that helps you be productive.

Elicit helpful feedback from various people at various stages . You might be tempted to keep your writing to yourself until you think it’s brilliant, but you can lower the stakes tremendously if you make eliciting feedback a regular part of your writing process. Your friends can feel like a safer audience for ideas or drafts in their early stages. Someone outside your department may provide interesting perspectives from their discipline that spark your own thinking. See this handout on getting feedback for productive moments for feedback, the value of different kinds of feedback providers, and strategies for eliciting what’s most helpful to you. Make this a recurring part of your writing process. Schedule it to help you hit deadlines.

Change the writing task . When you don’t feel like writing, you can do something different or you can do something differently. Make a list of all the little things you need to do for a given section of the dissertation, no matter how small. Choose a task based on your energy level. Work on Grad School requirements: reformat margins, work on bibliography, and all that. Work on your acknowledgements. Remember all the people who have helped you and the great ideas they’ve helped you develop. You may feel more like working afterward. Write a part of your dissertation as a letter or email to a good friend who would care. Sometimes setting aside the academic prose and just writing it to a buddy can be liberating and help you get the ideas out there. You can make it sound smart later. Free-write about why you’re stuck, and perhaps even about how sick and tired you are of your dissertation/advisor/committee/etc. Venting can sometimes get you past the emotions of writer’s block and move you toward creative solutions. Open a separate document and write your thoughts on various things you’ve read. These may or may note be coherent, connected ideas, and they may or may not make it into your dissertation. They’re just notes that allow you to think things through and/or note what you want to revisit later, so it’s perfectly fine to have mistakes, weird organization, etc. Just let your mind wander on paper.

Develop habits that foster productivity and may help you develop a productive writing model for post-dissertation writing . Since dissertations are very long projects, cultivating habits that will help support your work is important. You might check out Helen Sword’s work on behavioral, artisanal, social, and emotional habits to help you get a sense of where you are in your current habits. You might try developing “rituals” of work that could help you get more done. Lighting incense, brewing a pot of a particular kind of tea, pulling out a favorite pen, and other ritualistic behaviors can signal your brain that “it is time to get down to business.” You can critically think about your work methods—not only about what you like to do, but also what actually helps you be productive. You may LOVE to listen to your favorite band while you write, for example, but if you wind up playing air guitar half the time instead of writing, it isn’t a habit worth keeping.

The point is, figure out what works for you and try to do it consistently. Your productive habits will reinforce themselves over time. If you find yourself in a situation, however, that doesn’t match your preferences, don’t let it stop you from working on your dissertation. Try to be flexible and open to experimenting. You might find some new favorites!

Motivational strategies

Schedule a regular activity with other people that involves your dissertation. Set up a coworking date with your accountability buddies so you can sit and write together. Organize a chapter swap. Make regular appointments with your advisor. Whatever you do, make sure it’s something that you’ll feel good about showing up for–and will make you feel good about showing up for others.

Try writing in sprints . Many writers have discovered that the “Pomodoro technique” (writing for 25 minutes and taking a 5 minute break) boosts their productivity by helping them set small writing goals, focus intently for short periods, and give their brains frequent rests. See how one dissertation writer describes it in this blog post on the Pomodoro technique .

Quit while you’re ahead . Sometimes it helps to stop for the day when you’re on a roll. If you’ve got a great idea that you’re developing and you know where you want to go next, write “Next, I want to introduce x, y, and z and explain how they’re related—they all have the same characteristics of 1 and 2, and that clinches my theory of Q.” Then save the file and turn off the computer, or put down the notepad. When you come back tomorrow, you will already know what to say next–and all that will be left is to say it. Hopefully, the momentum will carry you forward.

Write your dissertation in single-space . When you need a boost, double space it and be impressed with how many pages you’ve written.

Set feasible goals–and celebrate the achievements! Setting and achieving smaller, more reasonable goals ( SMART goals ) gives you success, and that success can motivate you to focus on the next small step…and the next one.

Give yourself rewards along the way . When you meet a writing goal, reward yourself with something you normally wouldn’t have or do–this can be anything that will make you feel good about your accomplishment.

Make the act of writing be its own reward . For example, if you love a particular coffee drink from your favorite shop, save it as a special drink to enjoy during your writing time.

Try giving yourself “pre-wards” —positive experiences that help you feel refreshed and recharged for the next time you write. You don’t have to “earn” these with prior work, but you do have to commit to doing the work afterward.

Commit to doing something you don’t want to do if you don’t achieve your goal. Some people find themselves motivated to work harder when there’s a negative incentive. What would you most like to avoid? Watching a movie you hate? Donating to a cause you don’t support? Whatever it is, how can you ensure enforcement? Who can help you stay accountable?

Affective strategies

Build your confidence . It is not uncommon to feel “imposter phenomenon” during the course of writing your dissertation. If you start to feel this way, it can help to take a few minutes to remember every success you’ve had along the way. You’ve earned your place, and people have confidence in you for good reasons. It’s also helpful to remember that every one of the brilliant people around you is experiencing the same lack of confidence because you’re all in a new context with new tasks and new expectations. You’re not supposed to have it all figured out. You’re supposed to have uncertainties and questions and things to learn. Remember that they wouldn’t have accepted you to the program if they weren’t confident that you’d succeed. See our self-scripting handout for strategies to turn these affirmations into a self-script that you repeat whenever you’re experiencing doubts or other negative thoughts. You can do it!

Appreciate your successes . Not meeting a goal isn’t a failure–and it certainly doesn’t make you a failure. It’s an opportunity to figure out why you didn’t meet the goal. It might simply be that the goal wasn’t achievable in the first place. See the SMART goal handout and think through what you can adjust. Even if you meant to write 1500 words, focus on the success of writing 250 or 500 words that you didn’t have before.

Remember your “why.” There are a whole host of reasons why someone might decide to pursue a PhD, both personally and professionally. Reflecting on what is motivating to you can rekindle your sense of purpose and direction.

Get outside support . Sometimes it can be really helpful to get an outside perspective on your work and anxieties as a way of grounding yourself. Participating in groups like the Dissertation Support group through CAPS and the Dissertation Boot Camp can help you see that you’re not alone in the challenges. You might also choose to form your own writing support group with colleagues inside or outside your department.

Understand and manage your procrastination . When you’re writing a long dissertation, it can be easy to procrastinate! For instance, you might put off writing because the house “isn’t clean enough” or because you’re not in the right “space” (mentally or physically) to write, so you put off writing until the house is cleaned and everything is in its right place. You may have other ways of procrastinating. It can be helpful to be self-aware of when you’re procrastinating and to consider why you are procrastinating. It may be that you’re anxious about writing the perfect draft, for example, in which case you might consider: how can I focus on writing something that just makes progress as opposed to being “perfect”? There are lots of different ways of managing procrastination; one way is to make a schedule of all the things you already have to do (when you absolutely can’t write) to help you visualize those chunks of time when you can. See this handout on procrastination for more strategies and tools for managing procrastination.

Your topic, your advisor, and your committee: Making them work for you

By the time you’ve reached this stage, you have probably already defended a dissertation proposal, chosen an advisor, and begun working with a committee. Sometimes, however, those three elements can prove to be major external sources of frustration. So how can you manage them to help yourself be as productive as possible?

Managing your topic

Remember that your topic is not carved in stone . The research and writing plan suggested in your dissertation proposal was your best vision of the project at that time, but topics evolve as the research and writing progress. You might need to tweak your research question a bit to reduce or adjust the scope, you might pare down certain parts of the project or add others. You can discuss your thoughts on these adjustments with your advisor at your check ins.

Think about variables that could be cut down and how changes would affect the length, depth, breadth, and scholarly value of your study. Could you cut one or two experiments, case studies, regions, years, theorists, or chapters and still make a valuable contribution or, even more simply, just finish?

Talk to your advisor about any changes you might make . They may be quite sympathetic to your desire to shorten an unwieldy project and may offer suggestions.

Look at other dissertations from your department to get a sense of what the chapters should look like. Reverse-outline a few chapters so you can see if there’s a pattern of typical components and how information is sequenced. These can serve as models for your own dissertation. See this video on reverse outlining to see the technique.

Managing your advisor

Embrace your evolving status . At this stage in your graduate career, you should expect to assume some independence. By the time you finish your project, you will know more about your subject than your committee does. The student/teacher relationship you have with your advisor will necessarily change as you take this big step toward becoming their colleague.

Revisit the alliance . If the interaction with your advisor isn’t matching the original agreement or the original plan isn’t working as well as it could, schedule a conversation to revisit and redesign your working relationship in a way that could work for both of you.

Be specific in your feedback requests . Tell your advisor what kind of feedback would be most helpful to you. Sometimes an advisor can be giving unhelpful or discouraging feedback without realizing it. They might make extensive sentence-level edits when you really need conceptual feedback, or vice-versa, if you only ask generally for feedback. Letting your advisor know, very specifically, what kinds of responses will be helpful to you at different stages of the writing process can help your advisor know how to help you.

Don’t hide . Advisors can be most helpful if they know what you are working on, what problems you are experiencing, and what progress you have made. If you haven’t made the progress you were hoping for, it only makes it worse if you avoid talking to them. You rob yourself of their expertise and support, and you might start a spiral of guilt, shame, and avoidance. Even if it’s difficult, it may be better to be candid about your struggles.

Talk to other students who have the same advisor . You may find that they have developed strategies for working with your advisor that could help you communicate more effectively with them.

If you have recurring problems communicating with your advisor , you can make a change. You could change advisors completely, but a less dramatic option might be to find another committee member who might be willing to serve as a “secondary advisor” and give you the kinds of feedback and support that you may need.

Managing your committee

Design the alliance . Talk with your committee members about how much they’d like to be involved in your writing process, whether they’d like to see chapter drafts or the complete draft, how frequently they’d like to meet (or not), etc. Your advisor can guide you on how committees usually work, but think carefully about how you’d like the relationship to function too.

Keep in regular contact with your committee , even if they don’t want to see your work until it has been approved by your advisor. Let them know about fellowships you receive, fruitful research excursions, the directions your thinking is taking, and the plans you have for completion. In short, keep them aware that you are working hard and making progress. Also, look for other ways to get facetime with your committee even if it’s not a one-on-one meeting. Things like speaking with them at department events, going to colloquiums or other events they organize and/or attend regularly can help you develop a relationship that could lead to other introductions and collaborations as your career progresses.

Share your struggles . Too often, we only talk to our professors when we’re making progress and hide from them the rest of the time. If you share your frustrations or setbacks with a knowledgeable committee member, they might offer some very helpful suggestions for overcoming the obstacles you face—after all, your committee members have all written major research projects before, and they have probably solved similar problems in their own work.

Stay true to yourself . Sometimes, you just don’t entirely gel with your committee, but that’s okay. It’s important not to get too hung up on how your committee does (or doesn’t) relate to you. Keep your eye on the finish line and keep moving forward.

Dissertation Explained: A Grad Student’s Guide

Updated: August 7, 2023

Published: March 10, 2020

Higher education is filled with milestones. When completing your PhD , you will be required to complete a dissertation. Even if you’ve heard this word thrown around before, you still may be questioning “What is a dissertation?” It’s a common question, especially for those considering to join or are already in a graduate program. As such, here’s everything you need to know about dissertations.

What is a Dissertation?

A dissertation is a written document that details research. A dissertation also signifies the completion of your PhD program. It is required to earn a PhD degree, which stands for Doctor of Philosophy.

A PhD is created from knowledge acquired from:

1. Coursework:

A PhD program consists of academic courses that are usually small in size and challenging in content. Most PhD courses consist of a high amount and level of reading and writing per week. These courses will help prepare you for your dissertation as they will teach research methodology.

2. Research:

For your dissertation, it is likely that you will have the choice between performing your own research on a subject , or expanding on existing research. Likely, you will complete a mixture of the two. For those in the hard sciences, you will perform research in a lab. For those in humanities and social sciences, research may mean gathering data from surveys or existing research.

3. Analysis:

Once you have collected the data you need to prove your point, you will have to analyze and interpret the information. PhD programs will prepare you for how to conduct analysis, as well as for how to position your research into the existing body of work on the subject matter.

4. Support:

The process of writing and completing a dissertation is bigger than the work itself. It can lead to research positions within the university or outside companies. It may mean that you will teach and share your findings with current undergraduates, or even be published in academic journals. How far you plan to take your dissertation is your choice to make and will require the relevant effort to accomplish your goals.

Moving from Student to Scholar

In essence, a dissertation is what moves a doctoral student into becoming a scholar. Their research may be published, shared, and used as educational material moving forwards.

Thesis vs. Dissertation

Basic differences.

Grad students may conflate the differences between a thesis and a dissertation.

Simply put, a thesis is what you write to complete a master’s degree. It summarizes existing research and signifies that you understand the subject matter deeply.

On the other hand, a dissertation is the culmination of a doctoral program. It will likely require your own research and it can contribute an entirely new idea into your field.

Structural Differences

When it comes to the structure, a thesis and dissertation are also different. A thesis is like the research papers you complete during undergraduate studies. A thesis displays your ability to think critically and analyze information. It’s less based on research that you’ve completed yourself and more about interpreting and analyzing existing material. They are generally around 100 pages in length.

A dissertation is generally two to three times longer compared to a thesis. This is because the bulk of the information is garnered from research you’ve performed yourself. Also, if you are providing something new in your field, it means that existing information is lacking. That’s why you’ll have to provide a lot of data and research to back up your claims.

Your Guide: Structuring a Dissertation

Dissertation length.

The length of a dissertation varies between study level and country. At an undergraduate level, this is more likely referred to as a research paper, which is 10,000 to 12,000 words on average. At a master’s level, the word count may be 15,000 to 25,000, and it will likely be in the form of a thesis. For those completing their PhD, then the dissertation could be 50,000 words or more.

Format of the dissertation.

Here are the items you must include in a dissertation. While the format may slightly vary, here’s a look at one way to format your dissertation:

1. Title page:

This is the first page which includes: title, your name, department, degree program, institution, and submission date. Your program may specify exactly how and what they want you to include on the title page.

2. Acknowledgements:

This is optional, but it is where you can express your gratitude to those who have helped you complete your dissertation (professors, research partners, etc.).

3. Abstract:

The abstract is about 150-300 words and summarizes what your research is about. You state the main topic, the methods used, the main results, and your conclusion.

4. Table of Contents

Here, you list the chapter titles and pages to serve as a wayfinding tool for your readers.

5. List of Figures and Tables:

This is like the table of contents, but for graphs and figures.

6. List of Abbreviations:

If you’ve constantly abbreviated words in your content, define them in a list at the beginning.

7. Glossary:

In highly specialized work, it’s likely that you’ve used words that most people may not understand, so a glossary is where you define these terms.

8. Introduction:

Your introduction sets up the topic, purpose, and relevance. It’s where readers will understand what they expect to gain from your dissertation.

9. Literature Review / Theoretical Framework:

Based on the research you performed to create your own dissertation, you’ll want to summarize and address the gaps in what you researched.

10. Methodology

This is where you define how you conducted your research. It offers credibility for you as a source of information. You should give all the details as to how you’ve conducted your research, including: where and when research took place, how it was conducted, any obstacles you faced, and how you justified your findings.

11. Results:

This is where you share the results that have helped contribute to your findings.

12. Discussion:

In the discussion section, you explain what these findings mean to your research question. Were they in line with your expectations or did something jump out as surprising? You may also want to recommend ways to move forward in researching and addressing the subject matter.

13. Conclusion:

A conclusion ties it all together and summarizes the answer to the research question and leaves your reader clearly understanding your main argument.

14. Reference List:

This is the equivalent to a works cited or bibliography page, which documents all the sources you used to create your dissertation.

15. Appendices:

If you have any information that was ancillary to creating the dissertation, but doesn’t directly fit into its chapters, then you can add it in the appendix.

Drafting and Rewriting

As with any paper, especially one of this size and importance, the writing requires a process. It may begin with outlines and drafts, and even a few rewrites. It’s important to proofread your dissertation for both grammatical mistakes, but also to ensure it can be clearly understood.

It’s always useful to read your writing out loud to catch mistakes. Also, if you have people who you trust to read it over — like a peer, family member, mentor, or professor — it’s very helpful to get a second eye on your work.

How is it Different from an Essay?

There are a few main differences between a dissertation and an essay. For starters, an essay is relatively short in comparison to a dissertation, which includes your own body of research and work. Not only is an essay shorter, but you are also likely given the topic matter of an essay. When it comes to a dissertation, you have the freedom to construct your own argument, conduct your own research, and then prove your findings.

Types of Dissertations

You can choose what type of dissertation you complete. Often, this depends on the subject and doctoral degree, but the two main types are:

This relies on conducting your own research.

Non-empirical:

This relies on studying existing research to support your argument.

More things you should know.

A dissertation is certainly no easy feat. Here’s a few more things to remember before you get started writing your own:

1. Independent by Nature:

The process of completing a dissertation is self-directed, and therefore can feel overwhelming. However, if you approach it like the new experience that it is with an open-mind and willingness to learn, you will make it through!

2. Seek Support:

There are countless people around to offer support. From professors to peers, you can always ask for help throughout the process.

3. Writing Skills:

The process of writing a dissertation will further hone your writing skills which will follow you throughout your life. These skills are highly transferable on the job, from having the ability to communicate to also developing analytical and critical thinking skills.

4. Time Management:

You can work backwards from the culmination of your program to break down this gargantuan task into smaller pieces. That way, you can manage your time to chip away at the task throughout the length of the program.

5. Topic Flexibility:

It’s okay to change subject matters and rethink the point of your dissertation. Just try as much as possible to do this early in the process so you don’t waste too much time and energy.

The Wrap Up

A dissertation marks the completion of your doctoral program and moves you from being a student to being a scholar. While the process is long and requires a lot of effort and energy, you have the power to lend an entirely new research and findings into your field of expertise.

As always, when in the thick of things, remember why you started. Completing both your dissertation and PhD is a commendable accomplishment.

Preparing For Your Dissertation Defense

13 Key Questions To Expect In The Viva Voce

By: Derek Jansen (MBA) & David Phair (PhD) . Reviewed By: Dr Eunice Rautenbach | June 2021

Preparing for your dissertation or thesis defense (also called a “viva voce”) is a formidable task . All your hard work over the years leads you to this one point, and you’ll need to defend yourself against some of the most experienced researchers you’ve encountered so far.

It’s natural to feel a little nervous.

In this post, we’ll cover some of the most important questions you should be able to answer in your viva voce, whether it’s for a Masters or PhD degree. Naturally, they might not arise in exactly the same form (some may not come up at all), but if you can answer these questions well, it means you’re in a good position to tackle your oral defense.

Viva Voce Prep: 13 Essential Questions

• What is your study about and why did you choose to research this in particular?
• How did your research questions evolve during the research process?
• How did you decide on which sources to include in your literature review?
• How did you design your study and why did you take this approach?
• How generalisable and valid are the findings?
• What were the main shortcomings and limitations created by your research design?
• How did your findings relate to the existing literature?
• What were your key findings in relation to the research questions?
• Were there any findings that surprised you?
• What biases may exist in your research?
• How can your findings be put into practice?
• How has your research contributed to current thinking in the field?
• If you could redo your research, how would you alter your approach?

#1: What is your study about and why did you choose to research this in particular?

This question, a classic party starter, is pretty straightforward.

What the dissertation or thesis committee is assessing here is your ability to clearly articulate your research aims, objectives and research questions in a concise manner. Concise is the keyword here – you need to clearly explain your research topic without rambling on for a half-hour. Don’t feel the need to go into the weeds here – you’ll have many opportunities to unpack the details later on.

In the second half of the question, they’re looking for a brief explanation of the justification of your research. In other words, why was this particular set of research aims, objectives and questions worth addressing? To address this question well in your oral defense, you need to make it clear what gap existed within the research and why that gap was worth filling.

#2: How did your research questions evolve during the research process?

Good research generally follows a long and winding path . It’s seldom a straight line (unless you got really lucky). What they’re assessing here is your ability to follow that path and let the research process unfold.

Specifically, they’ll want to hear about the impact that the literature review process had on you in terms of shaping the research aims, objectives and research questions . For example, you may have started with a certain set of aims, but then as you immersed yourself in the literature, you may have changed direction. Similarly, your initial fieldwork findings may have turned out some unexpected data that drove you to adjust or expand on your initial research questions.

Long story short – a good defense involves clearly describing your research journey , including all the twists and turns. Adjusting your direction based on findings in the literature or the fieldwork shows that you’re responsive , which is essential for high-quality research.

#3: How did you decide on which sources to include in your literature review?

A comprehensive literature review is the foundation of any high-quality piece of research. With this question, your dissertation or thesis committee are trying to assess which quality criteria and approach you used to select the sources for your literature review.

Typically, good research draws on both the seminal work in the respective field and more recent sources . In other words, a combination of the older landmark studies and pivotal work, along with up-to-date sources that build on to those older studies. This combination ensures that the study has a rock-solid foundation but is not out of date.

So, make sure that your study draws on a mix of both the “classics” and new kids on the block, and take note of any major evolutions in the literature that you can use as an example when asked this question in your viva voce.

#4: How did you design your study and why did you take this approach?

This is a classic methodological question that you can almost certainly expect in some or other shape.

What they’re looking for here is a clear articulation of the research design and methodology, as well as a strong justification of each choice . So, you need to be able to walk through each methodological choice and clearly explain both what you did and why you did it. The why is particularly important – you need to be able to justify each choice you made by clearly linking your design back to your research aims, objectives and research questions, while also taking into account practical constraints.

To ensure you cover every base, check out our research methodology vlog post , as well as our post covering the Research Onion .

#5: How generalizable and valid are the findings?

This question is aimed at specifically digging into your understanding of the sample and how that relates to the population, as well as potential validity issues in your methodology.

To answer question this well, you’ll need to critically assess your sample and findings and consider if they truly apply to the entire population, as well as whether they assessed what they set out to. Note that there are two components here – generalizability and validity . Generalizability is about how well the sample represents the population. Validity is about how accurately you’ve measured what you intended to measure .

To ace this part of your dissertation defense, make sure that you’re very familiar with the concepts of generalizability , validity and reliability , and how these apply to your research. Remember, you don’t need to achieve perfection – you just need to be aware of the strengths and weaknesses of your research (and how the weaknesses could be improved upon).

#6: What were the main shortcomings and limitations created by your research design?

This question picks up where the last one left off.

As I mentioned, it’s perfectly natural that your research will have shortcomings and limitations as a result of your chosen design and methodology. No piece of research is flawless. Therefore, a good dissertation defense is not about arguing that your work is perfect, but rather it’s about clearly articulating the strengths and weaknesses of your approach.

To address this question well, you need to think critically about all of the potential weaknesses your design may have, as well as potential responses to these (which could be adopted in future research) to ensure you’re well prepared for this question. For a list of common methodological limitations, check out our video about research limitations here .

#7: How did your findings relate to the existing literature?

This common dissertation defense question links directly to your discussion chapter , where you would have presented and discussed the findings in relation to your literature review.

What your dissertation or thesis committee is assessing here is your ability to compare your study’s findings to the findings of existing research . Specifically, you need to discuss which findings aligned with existing research and which findings did not. For those findings that contrasted against existing research, you should also explain what you believe to be the reasons for this.

As with many questions in a viva voce, it’s both the what and the why that matter here. So, you need to think deeply about what the underlying reasons may be for both the similarities and differences between your findings and those of similar studies.

#8: What were your key findings in relation to the research questions?

This question is similar to the last one in that it too focuses on your research findings. However, here the focus is specifically on the findings that directly relate to your research questions (as opposed to findings in general).

So, a good way to prepare for this question is to step back and revisit your research questions . Ask yourself the following:

• What exactly were you asking in those questions, and what did your research uncover concerning them?
• Which questions were well answered by your study and which ones were lacking?
• Why were they lacking and what more could be done to address this in future research?

Conquering this part dissertation defense requires that you focus squarely on the research questions. Your study will have provided many findings (hopefully!), and not all of these will link directly to the research questions. Therefore, you need to clear your mind of all of the fascinating side paths your study may have lead you down and regain a clear focus on the research questions .

#9: Were there any findings that surprised you?

This question is two-pronged.

First, you should discuss the surprising findings that were directly related to the original research questions . Going into your research, you likely had some expectations in terms of what you would find, so this is your opportunity to discuss the outcomes that emerged as contrary to what you initially expected. You’ll also want to think about what the reasons for these contrasts may be.

Second, you should discuss the findings that weren’t directly related to the research questions, but that emerged from the data set . You may have a few or you may have none – although generally there are a handful of interesting musings that you can glean from the data set. Again, make sure you can articulate why you find these interesting and what it means for future research in the area.

What the committee is looking for in this type of question is your ability to interpret the findings holistically and comprehensively , and to respond to unexpected data. So, take the time to zoom out and reflect on your findings thoroughly.

#10: What biases may exist in your research?

Biases… we all have them.

For this question, you’ll need to think about potential biases in your research , in the data itself but also in your interpretation of the data. With this question, your committee is assessing whether you have considered your own potential biases and the biases inherent in your analysis approach (i.e. your methodology). So, think carefully about these research biases and be ready to explain how these may exist in your study.

In an oral defense, this question is often followed up with a question on how the biases were mitigated or could be mitigated in future research. So, give some thought not just to what biases may exist, but also the mitigation measures (in your own study and for future research).

#11: How can your findings be put into practice?

Another classic question in the typical viva voce.

With this question, your committee is assessing your ability to bring your findings back down to earth and demonstrate their practical value and application. Importantly, this question is not about the contribution to academia or the overall field of research (we’ll get to that next) – it is specifically asking about how this newly created knowledge can be used in the real world.

Naturally, the actionability of your findings will vary depending on the nature of your research topic. Some studies will produce many action points and some won’t. If you’re researching marketing strategies within an industry, for example, you should be able to make some very specific recommendations for marketing practitioners in that industry.

To help you flesh out points for this question, look back at your original justification for the research (i.e. in your introduction and literature review chapters). What were the driving forces that led you to research your specific topic? That justification should help you identify ways in which your findings can be put into practice.

#12: How has your research contributed to current thinking in the field?

While the previous question was aimed at practical contribution, this question is aimed at theoretical contribution . In other words, what is the significance of your study within the current body of research? How does it fit into the existing research and what does it add to it?

This question is often asked by a field specialist and is used to assess whether you’re able to place your findings into the research field to critically convey what your research contributed. This argument needs to be well justified – in other words, you can’t just discuss what your research contributed, you need to also back each proposition up with a strong why .

To answer this question well, you need to humbly consider the quality and impact of your work and to be realistic in your response. You don’t want to come across as arrogant (“my work is groundbreaking”), nor do you want to undersell the impact of your work. So, it’s important to strike the right balance between realistic and pessimistic .

This question also opens the door to questions about potential future research . So, think about what future research opportunities your study has created and which of these you feel are of the highest priority.

#13: If you could redo your research, how would you alter your approach?

This question is often used to wrap up a viva voce as it brings the discussion full circle.

Here, your committee is again assessing your ability to clearly identify and articulate the limitations and shortcomings of your research, both in terms of research design and topic focus . Perhaps, in hindsight, it would have been better to use a different analysis method or data set. Perhaps the research questions should have leaned in a slightly different direction. And so on.

This question intends to assess whether you’re able to look at your work critically , assess where the weaknesses are and make recommendations for the future . This question often sets apart those who did the research purely because it was required, from those that genuinely engaged with their research. So, don’t hold back here – reflect on your entire research journey ask yourself how you’d do things differently if you were starting with a  blank canvas today.

Recap: The 13 Key Dissertation Defense Questions

To recap, here are the 13 questions you need to be ready for to ace your dissertation or thesis oral defense:

As I mentioned, this list of dissertation defense questions is certainly not exhaustive – don’t assume that we’ve covered every possible question here. However, these questions are quite likely to come up in some shape or form in a typical dissertation or thesis defense, whether it’s for a Master’s degree, PhD or any other research degree.
