If you're about to complete, or have ever completed a graduate degree, you have most likely come across the term "thesis defense." In many countries, to finish a graduate degree, you have to write a thesis .

A thesis is a large paper, or multi-chapter work, based on a topic relating to your field of study.

Once you hand in your thesis, you will be assigned a date to defend your work. Your thesis defense meeting usually consists of you and a committee of two or more professors working in your program. It may also include other people, like professionals from other colleges or those who are working in your field.

During your thesis defense, you will be asked questions about your work. The main purpose of your thesis defense is for the committee to make sure that you actually understand your field and focus area.

The questions are usually open-ended and require the student to think critically about their work. By the time of your thesis defense, your paper has already been evaluated. The questions asked are not designed so that you actually have to aggressively "defend" your work; often, your thesis defense is more of a formality required so that you can get your degree.

• Check with your department about requirements and timing.
• Re-read your thesis.
• Anticipate questions and prepare for them.
• Create a back-up plan to deal with technology hiccups.
• Plan de-stressing activities both before, and after, your defense.

How long your oral thesis defense is depends largely on the institution and requirements of your degree. It is best to consult your department or institution about this. In general, a thesis defense may take only 20 minutes, but it may also take two hours or more. The length also depends on how much time is allocated to the presentation and questioning part.

Tip: Check with your department or institution as soon as possible to determine the approved length for a thesis defense.

First of all, be aware that a thesis defense varies from country to country. This is just a general overview, but a thesis defense can take many different formats. Some are closed, others are public defenses. Some take place with two committee members, some with more examiners.

The same goes for the length of your thesis defense, as mentioned above. The most important first step for you is to clarify with your department what the structure of your thesis defense will look like. In general, your thesis defense will include:

• your presentation of around 20-30 minutes
• questions from the committee
• questions from the audience (if the defense is public and the department allows it)

You might have to give a presentation, often with Powerpoint, Google slides, or Keynote slides. Make sure to prepare an appropriate amount of slides. A general rule is to use about 10 slides for a 20-minute presentation.

But that also depends on your specific topic and the way you present. The good news is that there will be plenty of time ahead of your thesis defense to prepare your slides and practice your presentation alone and in front of friends or family.

Tip: Practice delivering your thesis presentation in front of family, friends, or colleagues.

You can prepare your slides by using information from your thesis' first chapter (the overview of your thesis) as a framework or outline. Substantive information in your thesis should correspond with your slides.

Make sure your slides are of good quality— both in terms of the integrity of the information and the appearance. If you need more help with how to prepare your presentation slides, both the ASQ Higher Education Brief and James Hayton have good guidelines on the topic.

The committee will ask questions about your work after you finish your presentation. The questions will most likely be about the core content of your thesis, such as what you learned from the study you conducted. They may also ask you to summarize certain findings and to discuss how your work will contribute to the existing body of knowledge.

Tip: Read your entire thesis in preparation of the questions, so you have a refreshed perspective on your work.

While you are preparing, you can create a list of possible questions and try to answer them. You can foresee many of the questions you will get by simply spending some time rereading your thesis.

Here are a few tips on how to prepare for your thesis defense:

You can absolutely prepare for most of the questions you will be asked. Read through your thesis and while you're reading it, create a list of possible questions. In addition, since you will know who will be on the committee, look at the academic expertise of the committee members. In what areas would they most likely be focused?

If possible, sit at other thesis defenses with these committee members to get a feel for how they ask and what they ask. As a graduate student, you should generally be adept at anticipating test questions, so use this advantage to gather as much information as possible before your thesis defense meeting.

Your thesis defense is a formal event, often the entire department or university is invited to participate. It signals a critical rite of passage for graduate students and faculty who have supported them throughout a long and challenging process.

While most universities don't have specific rules on how to dress for that event, do regard it with dignity and respect. This one might be a no-brainer, but know that you should dress as if you were on a job interview or delivering a paper at a conference.

It might help you deal with your stress before your thesis defense to entrust someone with the smaller but important responsibilities of your defense well ahead of schedule. This trusted person could be responsible for:

• preparing the room of the day of defense
• setting up equipment for the presentation
• preparing and distributing handouts

Technology is unpredictable. Life is too. There are no guarantees that your Powerpoint presentation will work at all or look the way it is supposed to on the big screen. We've all been there. Make sure to have a plan B for these situations. Handouts can help when technology fails, and an additional clean shirt can save the day if you have a spill.

One of the scariest aspects of the defense is the possibility of being asked a question you can't answer. While you can prepare for some questions, you can never know exactly what the committee will ask.

There will always be gaps in your knowledge. But your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. You are not expected to know everything.

James Hayton writes on his blog that examiners will sometimes even ask questions they don't know the answer to, out of curiosity, or because they want to see how you think. While it is ok sometimes to just say "I don't know", he advises to try something like "I don't know, but I would think [...] because of x and y, but you would need to do [...] in order to find out.” This shows that you have the ability to think as an academic.

You will be nervous. But your examiners will expect you to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions, for example. Dora Farkas at finishyourthesis.com notes that it’s a myth that thesis committees are out to get you.

Two common symptoms of being nervous are talking really fast and nervous laughs. Try to slow yourself down and take a deep breath. Remember what feels like hours to you are just a few seconds in real life.

• Try meditational breathing right before your defense.
• Get plenty of exercise and sleep in the weeks prior to your defense.
• Have your clothes or other items you need ready to go the night before.
• During your defense, allow yourself to process each question before answering.
• Go to dinner with friends and family, or to a fun activity like mini-golf, after your defense.

Allow yourself to process each question, respond to it, and stop talking once you have responded. While a smile can often help dissolve a difficult situation, remember that nervous laughs can be irritating for your audience.

We all make mistakes and your thesis defense will not be perfect. However, careful preparation, mindfulness, and confidence can help you feel less stressful both before, and during, your defense.

Finally, consider planning something fun that you can look forward to after your defense.

It is completely normal to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions for example if needed. Slow yourself down, and take a deep breath.

Your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. James Hayton writes on his blog that it is ok sometimes to just say "I don't know", but he advises to try something like "I don't know, but I would think [...] because of x and y, you would need to do [...] in order to find out".

Your Powerpoint presentation can get stuck or not look the way it is supposed to do on the big screen. It can happen and your supervisors know it. In general, handouts can always save the day when technology fails.

• Dress for success.
• Ask for help setting up.
• Have a backup plan (in case technology fails you).
• Deal with your nerves.

The top 10 thesis defense questions (+ how to prepare strong answers)

Crafting a thesis is significant, but defending it often feels like the ultimate test. While nerve-wracking, proper preparation can make it manageable. Prepare for your thesis defense with insights on the top questions you can expect, including strategies for answering convincingly.

Mastering the thesis defense: cultivate a success mindset

Question 1: why did you choose this particular topic for your research, question 2: how does your research contribute to the existing body of knowledge, question 3: what are the key findings of your research, question 4: can you defend your research methodology, question 5: how did you analyze the data and what challenges did you encounter, question 6: what theoretical frameworks or references underpin your research, question 7: how did you address ethical considerations in your research, question 8: in what ways does your research contribute to the field, question 9: how did you ensure your research was free from bias, question 10: where can future research go from here.

Nurturing a success mindset for your defense is pivotal. This means adopting a mental outlook geared towards achieving favorable outcomes during your thesis defense. To truly excel in this pivotal academic moment, it’s imperative to cultivate both confidence and composure.

Confidence enables you to present your research with conviction, while composure allows you to navigate any challenges with grace and clarity.

Ace Your Thesis Defense: Proven Techniques To Defend Your Thesis

You’ve done the research, written the thesis, and now it’s time to defend your hard work in what could be the most significant academic presentation of your life.

Nervous? Don’t be.

This blog is designed to give you the insider tips and techniques that can help you sail through your thesis defense like a pro. 

Whether you’re working towards a master’s or a Ph.D., understanding the nuances of a thesis defense can make all the difference.

Read on to find out how to prepare, what to expect, and how to impress your committee. With this guide, you’ll not only be well-prepared but may actually find yourself enjoying the experience.

What is a Thesis Defense?

A thesis defense is the culminating event in a graduate student’s academic journey, often compared to the “final boss” in a video game.

However, contrary to popular anxiety-inducing belief, it’s not a test; it’s more akin to a scholarly discussion.

After years of research and writing, students present their thesis to a committee made up of subject matter experts.

The purpose is to demonstrate expertise, defend research choices, and prove that they have made a contribution to their field.

What Does a Thesis Defense Look Like?

 Students should expect to give an initial presentation, followed by a Q&A session where committee members probe further. It can go on for up to 3+ hours. 

Typically there are external experts in a particular field who have read the thesis and have now attended your university to watch your presentation and ask you questions about it. It can be done in a public forum or privately in a closed room.

Expect queries that dig into your methodology, specific results, and how your work advances the current body of knowledge.

Once you have answered the questions the candidate is often asked to leave the room while the experts deliberate – it can be quite an anxious wait. 

Top tips from PhDs for a thesis defence – FAQs

• Read Your Thesis Again : Even if you think you’ve completed your thesis, allocate time to read it again to refresh your memory.
• Prepare for Open-Ended Questions : Your committee will ask questions that are usually open-ended and require deep understanding. Prepare answers in advance.
• Know the Purpose : Understand that the purpose of a thesis defense is to prove you’re an expert in your field, not to interrogate you.
• Conduct a Q&A Session : Practice a question and answer session with your advisor or a professor to prepare for possible questions.
• Time Management : Be aware that the length for a thesis defense can vary. Some may take only 20 minutes, so focus on main points.
• Public Speaking : Use this as a chance to hone your public speaking skills. Many graduate degree programs require an oral defense or practicum.
• Committee Members : Know who is on your committee and what they specialize in to anticipate the types of questions they might ask.
• Consult Your Advisor : Your advisor can give you an overview of what to expect, helping you feel more confident.
• Be Ready for Formalities : Realize that the defense is a formal academic formality; it’s not only a presentation but also an evaluation of your ability to think critically.
• Understand the Evaluation : Your defense isn’t just about defending a thesis; it’s also about showing you can contribute to the existing body of knowledge in your graduate program.
• Prepare for Varied Questions : Questions may cover everything from your thesis topic to your research methods, so be prepared for a wide range.
• Think of It as a Job Interview : Like a job interview, your thesis defense gives you a chance to show your expertise. Be as prepared as possible.

How to Prepare for Your Thesis Defense

When it comes to prepping for your thesis defense, organization and mindset are crucial.

Sure, you’ve spent months, if not years, researching and writing your thesis, but now it’s time to defend it in front of your committee. One insider tip is to treat the defense as a “discussion,” not a “test.” Your thesis committee is there to engage in an academic conversation with you; they’re not looking to trip you up.

One golden nugget of advice is to print out a copy of your thesis, but not just any printout will do.

Create a “defense-friendly” format, complete with tabs marking significant sections and even color-coding if you’re a visual person.

The point is to make the document easy to navigate during the defense when your committee members ask questions you need to address promptly.

Beyond having the thesis itself in hand, go the extra mile and print out five or fewer key pages that may be the subject of focused discussion.

This can include graphs or data that didn’t make it into the final thesis but could still be relevant. For instance, one student printed out a large-scale version of a critical diagram from their thesis and had it ready when committee members inevitably asked about it.

The committee was impressed, and it made for a smoother defense.

To prepare, make sure you’ve allotted sufficient time for the process—ten days is a good benchmark. Take one day to review your thesis in its entirety and then a few days for each chapter. Revisit literature, anticipate questions, and try to see your work from the committee’s perspective.

Make use of prep templates available online, which can help you consider your thesis’ different parts in-depth. So when D-Day comes, you’re not just prepared; you’re defense-ready.

My Experience with a Thesis Defense

When it came time for my thesis defense, I was a bundle of nerves despite having practiced extensively.

I had simulated the entire defense multiple times with friends and even consulted my advisor for last-minute tips. To my surprise, the questions posed by the committee weren’t as hard as I had anticipated.

They seemed to flow naturally from the work I had done, and my extensive preparation made it easier to respond confidently. The time during the defense passed more quickly than I had imagined, adding to the sense of flow.

What was unexpected was how much I actually enjoyed the experience. The defense turned into a meaningful academic conversation, making me feel like a genuine expert in my field.

Wrapping up – prepare for a thesis defense

Defending your thesis is a significant milestone, whether you’re aiming for a master’s degree or pushing the boundaries of academia with a Ph.D. It’s the culmination of your hard work, the moment you demonstrate that you’ve written a good thesis and are ready to join the ranks of the experts in your field. For many students, the experience can be nerve-wracking, but as you’ve seen in this blog, it doesn’t have to be. 

From understanding the type of thesis defense questions you may encounter to gaining insights into the formalities involved, you now have the tools to prepare for a thesis defense effectively. The aim is not just to survive but to thrive, turning your defense into an enlightening academic conversation.

Your defense is more than just a hurdle to overcome; it’s an opportunity to showcase your research, your understanding, and your ability to contribute to your field. You’ve spent years preparing for this moment—take the time to prepare a little more, and the experience could be rewarding in ways you never expected.

The culmination of years of rigorous research, analysis, and academic dedication is often encapsulated in a single event – a successful thesis defence presentation. This pivotal moment in an academic journey can be both exhilarating and nerve-wracking. Success hinges on a well-prepared and effectively delivered presentation. In this comprehensive guide, we will delve into the key components of a successful thesis defence presentation, equipping you with the knowledge and insights necessary to navigate this critical milestone in your academic career.

10 Key Strategies To Defend Your Thesis

#1 clearly define your statement of thesis.

At the heart of every successful thesis defence presentation lies a well-articulated statement of thesis. This concise and focused sentence or two should encapsulate the core question or problem your research addresses. Peer review, a critical evaluation of your work by experts in the field, often commences with a thorough assessment of the clarity and relevance of your thesis statement. It is the compass that guides your entire presentation.

The statement of thesis serves as the cornerstone of an entire successful thesis defence presentation, and its importance cannot be overstated. This concise and focused sentence or two should encapsulate the core question or problem your research addresses. Think of it as the spark that ignites the intellectual journey you’re about to take your audience on.

When you consider the peer review process, it becomes clear that the experts in your field are like seasoned explorers, setting out on an intellectual expedition through your work. And where does their journey begin? With your thesis statement. It acts as the compass that guides their critical evaluation. They venture into the depths of your research, often commencing with a meticulous assessment of the clarity and relevance of your thesis statement. It’s not merely a formality; it’s a critical checkpoint to ensure that your compass is finely tuned and aligned with the path you’ve forged.

#2 Comprehensive Literature Review

A robust literature review demonstrates your understanding of the existing body of knowledge in your field. This component of your presentation should not merely summarise relevant literature but critically analyse it. Peer-reviewed journals, academic databases, and scholarly publications are invaluable resources for conducting a thorough literature review. Clearly demonstrate how your research fits into the existing landscape and adds a new dimension to the field.

Your literature review isn’t just a bibliography; it’s the evidence of your mastery over the existing body of knowledge in your field. It should be robust, showcasing your understanding and critical thinking abilities. Think of it as a treasure trove of insights from the minds of scholars who have paved the way before you.

Peer-reviewed journals, academic databases, and scholarly publications are the maps to this treasure trove. They are invaluable resources for conducting a thorough literature review. But remember, your role is not merely that of a summariser; you are an interpreter. Your presentation should not merely summarise relevant literature but critically analyse it. Imagine yourself as an art critic, dissecting each brushstroke to reveal the masterpiece that is your research. Show the audience how your research fits into the existing landscape and adds a new dimension to the field, like an artist contributing a unique piece to a gallery.

#3 Methodology and Data Collection

Describe in detail the methodologies employed in your research, addressing questions such as: How did you collect data? What tools or instruments did you use? How did you ensure the validity and reliability of your data? Peer review often scrutinises the rigor of your research methods, so be prepared to defend your choices and demonstrate their appropriateness for your study.

Your methodology is the blueprint of your research, and the data you collect are the bricks that build your thesis. This section deserves meticulous attention and clarity. Describe in detail the methodologies employed in your research. Address questions such as: How did you collect data? What tools or instruments did you use? How did you ensure the validity and reliability of your data? Think of it as the architectural plans that ensure your thesis stands tall and sturdy.

Keep in mind that peer review often scrutinises the rigor of your research methods. It’s like having a team of experienced builders inspecting your construction site for structural integrity. Be prepared to defend your choices and demonstrate their appropriateness for your study. You’re not just presenting data; you’re presenting the process behind the creation of your data.

#4 Data Analysis and Results

Present your findings with precision and clarity. Utilise graphs, tables, and visuals to enhance comprehension. Peer review experts will closely examine your data analysis methods to ensure they are statistically sound. Transparency in reporting results, including any limitations or unexpected outcomes, is crucial. Remember, transparency fosters credibility.

Your data is the treasure you’ve unearthed through your research, and it’s time to present it with precision and clarity. Visual aids like graphs, tables, and visuals should be your artistic tools. Imagine yourself as a storyteller, weaving a narrative with data points.

Peer review experts will closely examine your data analysis methods to ensure they are statistically sound. It’s akin to having statisticians double-check your calculations. Transparency in reporting results is paramount. Think of it as being transparent about the ingredients of a recipe; it fosters credibility. Be honest about any limitations or unexpected outcomes, just as a chef might explain a dish’s unique flavours. Transparency invites trust and understanding.

#5 Discussion and Interpretation

This is your opportunity to showcase your critical thinking skills. Discuss the implications of your findings in the context of your thesis statement and existing literature. Address any unanswered questions or areas for future research. Peer review experts will assess the depth of your analysis and the coherence of your interpretations.

This is the moment when your audience gets a glimpse of your critical thinking skills. It’s not just about presenting data; it’s about the story behind the data. Consider yourself a detective solving a complex mystery. Discuss the implications of your findings in the context of your thesis statement and existing literature.

Address any unanswered questions or areas for future research. This is your chance to engage your audience in a scholarly conversation. Peer review experts will assess the depth of your analysis and the coherence of your interpretations. Think of it as a roundtable discussion where your ideas are put to the test.

#6 Effective Presentation Skills

Engage your audience with effective presentation skills. Practice your delivery, ensuring that you maintain eye contact, speak clearly, and use appropriate gestures. A confident and composed demeanour goes a long way in conveying your expertise. Utilise visual aids sparingly and strategically to enhance, not overwhelm, your presentation.

As you step into the spotlight of your thesis defence presentation, imagine yourself as a performer on the academic stage. Engage your audience with effective presentation skills that not only convey your expertise but also hold their attention. Practice your delivery meticulously to ensure that you maintain eye contact, speak clearly, and use appropriate gestures.

Confidence is your best companion on this stage. A confident and composed demeanour goes a long way in conveying your mastery of the subject matter. Utilise visual aids sparingly and strategically to enhance, not overwhelm, your presentation. Think of them as props in a play, designed to complement your narrative, not steal the show.

#7 Anticipate and Address Questions

Be prepared for a barrage of questions from the thesis committee during and after your presentation. Anticipate potential queries based on your research and be ready to provide well-informed responses. Peer review often extends to this phase, assessing your ability to defend your research and engage in scholarly discourse.

The Q&A session during and after your presentation is a challenging yet essential phase. Imagine it as the part of your performance where the audience gets to interact with you directly. Be prepared for a barrage of questions from the thesis committee. Anticipate potential queries based on your research and be ready to provide well-informed responses.

Peer review often extends to this phase, assessing your ability to defend your research and engage in scholarly discourse. Think of it as a debate where you defend your thesis against the toughest opponents. Embrace questions as opportunities to showcase your expertise and deepen the understanding of your work.

#8 Time Management

Respect the allocated time for your presentation. Going over your time limit can be detrimental and reflects poorly on your preparation. Time management is a skill that not only demonstrates professionalism but also allows for a smoother and more focused presentation.

Time management is the conductor’s baton in the symphony of your presentation. It’s not just about keeping things on schedule; it’s about ensuring that your performance is harmonious and well-paced. Respect the allocated time for your presentation. Going over your time limit can be detrimental and reflects poorly on your preparation.

Think of your presentation as a well-rehearsed orchestral piece, with each section seamlessly flowing into the next. Time management is the key to orchestrating this performance effectively. It demonstrates professionalism and allows for a smoother and more focused presentation.

#9 Adaptability

Be ready to adapt to unforeseen circumstances or questions. Your ability to handle unexpected challenges with grace and knowledge can leave a positive impression on both your thesis committee and peer reviewers.

In the world of academia, as in life, surprises are inevitable. Be ready to adapt to unforeseen circumstances or questions. Your ability to handle unexpected challenges with grace and knowledge can leave a lasting positive impression on both your thesis committee and peer reviewers.

Think of this adaptability as the mark of a seasoned explorer who can navigate uncharted territory. The ability to pivot gracefully when faced with the unexpected demonstrates your resilience and expertise.

#10 Mock Defences and Feedback

Prior to your actual defence, conduct mock thesis defence presentations with peers or mentors. Seek constructive feedback to refine your presentation. This rehearsal process can help you identify areas that may require improvement and boost your confidence.

Before the curtain rises on your actual defence, consider the value of dress rehearsals in the world of theatre. Prior to your defence, conduct mock thesis defence presentations with peers or mentors. Seek constructive feedback to refine your presentation. This rehearsal process can help you identify areas that may require improvement and boost your confidence.

Think of these mock defences as a preview performance, an opportunity to fine-tune your act before the main event. Constructive feedback from trusted sources is like the guidance of seasoned directors, helping you polish your performance and ensure you’re ready for the spotlight.

How to Effectively Prepare for Your Thesis Defense

You’ve completed your research study, written your thesis, and think you’re done! If only it were this easy. Before you finish with your thesis, there is one last hurdle to overcome: the thesis defense.

What is a thesis defense?

A thesis defense is an opportunity for you to present your research study before other academic professionals who will evaluate the quality of your academic work. While a thesis defense can sometimes feel like a cross-examination in a court of law, in reality, there is no need to fear your thesis defense as long as you are well-prepared. In this article, we’ll talk about how to prepare for a thesis defense, what to expect at the defense itself, and what comes after your defense. 

Why do I have to defend my thesis?

At your thesis defense, you will discuss everything you’ve learned with a group of interested examiners who are eager to hear your thoughts.

The fundamental purpose of a thesis defense is to prove that you have mastered your subject and can be considered as a knowledgeable expert in your field, thereby allowing you to graduate successfully. For many students, a thesis is one of the first attempts at conducting original research and demonstrating that you are equipped to function as an independent expert in your field. If qualified academic professionals can assess your work, question your methods and results, and confirm that your study is sound and novel, then you meet the requirements.

The exact format and expectations for your thesis defense will differ depending on the region you study in and your institution’s rules for the thesis program. The thesis defense meeting may have just two or three examiners or may have a whole panel of examiners along with an audience. 

If the thought of facing your professors, peers, and parents to present your research study makes you feel dizzy, you aren’t alone . Moreover, a thesis defense is a great opportunity for you to hone your public speaking skills as well as talk about your research study. At your thesis defense, you will discuss everything you’ve learned with a group of interested examiners who are eager to hear your thoughts.

While the format for a thesis defense will vary, as mentioned above, most thesis defenses consist of:

• Presenting your research study (using PowerPoint or other similar tools)
• Answering questions from your thesis committee
• Receiving feedback from your thesis committee

So how can you prepare for it? Let’s talk about some important tips.

Preparing: Before the defense

It is useful to attend multiple defenses and ask others who have gone through the process what it was like.

The best way to prepare for a thesis defense is to attend other defenses at your institution so that you know what to expect. It is useful to attend multiple defenses and ask others who have gone through the process what it was like. Senior students are often happy to provide advice and can give you specific insights about particular examiners as well as details of the administrative process at your institution.

You should also talk to your thesis advisor well in advance of your defense about what to expect. Ask whether you need to shortlist your own committee, how long your presentation should be, and how long the thesis defense will be. The duration of a thesis defense varies by the degree level as well as the institution. On average, expect your defense to be at least an hour long, possibly longer for a Ph.D.

What should my presentation cover and how can I prepare it?

While preparing your presentation, also prepare a list of questions and answers that you think are likely to be asked by your committee.

You will need to prepare a presentation that will cover the details of your research study. It is wise to rehearse this presentation multiple times in advance of your thesis defense so that you will be comfortable when you actually present in front of your audience. While preparing your presentation, also prepare a list of questions and answers that you think are likely to be asked by your committee. If you can, enlist the help of a classmate or friend to be the examiner. They can ask you questions about your research study so you will be able to practice addressing these questions.

One mistake many students make is assuming that all members of their defense committee will thoroughly read their thesis prior to the defense. This is simply not always the case. For this reason, you should make sure your presentation makes sense to someone who has not actually read your thesis. A typical thesis defense presentation gives:

• An introduction to the topic
• Explains how the study is significant in the field
• Covers the main highlights of the methodology and results of the study
• Picks out the main points from the discussion and conclusion

What should I do the day before my defense?

Before your thesis defense, make sure you have backups of everything you need saved in multiple formats and multiple locations.

Before your thesis defense, make sure you have backups of everything you need to be saved in multiple formats and multiple locations. Put your presentation and your thesis on a USB drive, email it to yourself, upload it to the cloud, and print it out. Leave nothing to chance: you want to be absolutely prepared to defend your thesis short of an act of God obliterating the venue. In addition, make sure you prepare hard copies (printouts) of both your thesis and slideshow for the committee members. It need not be professionally bound at this stage, but they will appreciate having reference material on hand.

Finally, there are some practical steps to take in preparation for the thesis defense. Choose your outfit in advance (you should dress professionally) and practice presenting in it. You should also make sure you know the exact location of the thesis defense venue. Scope out the venue before your defense, if possible, so you can imagine yourself there while you rehearse. If you are presenting virtually, test all your equipment in advance and have a backup plan in case your internet goes out or your computer suddenly crashes. Most importantly, make sure that you eat well and get proper rest the night before. Don’t stay up late rehearsing last minute in the hopes of improving your chances of passing your defense. You will do much better if you are well-rested and alert. 

Time to shine: At the defense

Try to stay calm and remember you are not on trial!

What can you expect on the day of the defense?

Typically, you will enter the room, set up, and begin your presentation once the committee indicates that they are ready. As mentioned above, it is always advisable to bring hard copies of both your thesis and slideshow for the committee. That way, they can easily refer to what you are talking about as you present. Make sure you also bring a pencil and notebook with you to take notes, and some water, because you will get thirsty as you talk.

After you are done with the presentation, the committee members will ask questions. Try to stay calm and remember you are not on trial! Your committee generally wants you to succeed, but they also want you to prove that you really know what you’re talking about. Do your best to answer their questions and never be afraid to admit when you don’t know something. It is much better, to be honest than to be caught lying or making something up during your thesis defense.

After the question and answer session, depending on your institution, you may be asked to leave the room while the committee deliberates. You may also be present while they discuss the merits of your defense and make suggestions for how to revise it. Alternatively, they might adjourn to another room if there is a large audience present. After they deliberate, they will usually thank you for your time, and your defense will be over. At some institutions, they will inform you if you passed right away, while at others, you will find out after a few days. 

How does my committee decide if my work is good or not?

In general, you can expect your thesis defense and your thesis as a whole to be evaluated based on the below criteria:

• Whether the thesis meets the departmental requirements
• Whether the research study is logical and clear
• Whether the stated objectives are met in the study
• Use of primary and secondary literature
• Use of relevant and up-to-date sources
• Methodological rigor
• Your ability to critically analyze data, facts, relevant literature, and synthesize information into a coherent narrative
• Writing quality and flow
• The validity of your conclusions based on your data and analysis
• The relevance and importance of your research study in the field
• Your ability to clearly and coherently present what your thesis is about
• Your ability to answer questions about your work accurately and in-depth
• Your ability to acknowledge and consider other theories or perspectives and explain why you dismissed one theory in favor of another

In summary, the examining committee want to know:

• Did you meet the thesis criteria set by your institution?
• Did you perform high-quality research work?
• Do you know what you are talking about?

After the defense: What’s next?

After your thesis is approved, you will need to have it professionally bound and then submit copies to your university.

After your thesis defense, you should definitely celebrate and congratulate yourself for all your hard work! Unfortunately, you aren’t quite done yet. Although the committee may notify you about passing, it is also very likely that you will be asked to make some changes to your thesis before you are finally done. You should work with your advisor to finalize and incorporate any comments you received into your work as quickly as possible.

After your thesis is approved, you will need to have it professionally bound and then submit copies to your university. You will also get the chance to order copies for yourself. This process also differs by institution, so make sure you talk to the administration department to figure out what you need to do and when to complete this process.

All in all, while a thesis defense is a scary and overwhelming event, it is also an incredible achievement. Earning your degree is no small feat, and you should definitely feel proud of yourself once you have done it!

🎙️ How To Ace Your Viva Voce

Three Practical Tips To Help You Defend Your Thesis

By: Derek Jansen (MBA) and Ethar Al-Saraf (PhD) | July 2024

The viva voce or thesis defence is an event that often leaves students feeling a little intimidated. And understandably so. In this post, we’ll share three practical tips to help you prepare for your defence and enter the viva voce room with confidence.

Overview: Defending Your Research

• Practice 1:  Material and format
• Practice 2:  Strengths and weaknesses
• Practice 3:  Oral and visual
• Key takeaways

1. Know both your material and the format

Understanding every detail of your study is a given, but equally important is understanding the specific format of the defence at your institution. This includes knowing the expected duration of the presentation and discussion, whether there’s an audience (and what their role is), and the type of questions typically asked by the examiners. It’s also crucial to familiarise yourself with any changes in your research field that have occurred since you began your project to ensure that your knowledge is current and comprehensive .

Preparing for the unexpected by researching the examiners’ backgrounds can also give you an edge. So, make sure that you understand their areas of expertise and try to anticipate the angles from which they might approach your work. This knowledge can help you tailor your defence to address potential criticisms more effectively.

2. Be ready to discuss both strengths and weaknesses

A successful defence involves not only showcasing the strengths of your research but also openly discussing its limitations . Before your viva voce, take the time to critically assess your work and identify any potential weaknesse s or areas for improvement. Prepare reasoned responses to these issues, so that you can demonstrate your analytical ability and depth of understanding.

It can feel a bit uncomfortable, but it’s important to understand that constructive self-criticism shows a mature approach to your research . In practical terms, this means acknowledging that while your study has limitations, these do not detract from the value of your work – but rather point to opportunities for further research . This mindset can help transform perceived weaknesses into demonstrations of your critical thinking and commitment to the field – so, don’t shy away of exploring this side of things.

Need a helping hand?

3. Invest in presentation – both oral and visual

Provided your institution allows it (see point 1),  you’ll definitely want to invest the time to prepare a clear, concise, and well-organised presentation . Importantly, less is more when it comes to the visuals. Avoid overcrowding your slides with text – no one wants to stare at a wall of text while trying to listen to you. Instead, use your slide deck to complement what you’re saying , sticking to only key figures, quotes, or concise bullet points.

Needless to say, you’ll need to rehearse your presentation multiple times . Don’t fool yourself into thinking you can “wing it” – you’ll invariably land up just reading your slides and torturing your audience. Practice speaking clearly and passionately about your research, making eye contact, and engaging your audience. It might sound rather menial, but this sort of preparation work will help you remain calm and focused during the actual defence, even when faced with tough questions.

Wrapping Up

The viva voce is as much about demonstrating your knowledge as it is about showcasing your ability to engage in academic discourse at a high level . By thoroughly preparing, understanding the format, and practicing your presentation, you’ll be able to navigate your defence smoothly and present yourself as a competent academic.

Psst... there’s more!

Thesis defense: tips and know-how

If you are preparing to defend your thesis, you’ve come to the right place! This guide explains some pointers to consider when preparing for your thesis defense, both prior and during the thesis presentation. Before we can begin discussing some tips and best practices for preparing a thesis defense, we first need to define and differentiate between the different types of defenses that exist. Doctoral defenses (PhD defenses) follow a different format than bachelor or master thesis defenses. The format tends to vary greatly, depending on the country, so there are is no one size fit all policy with regards to the structure. There are however some general guideliens that are important to consider, regardless of the format.

What is a thesis defense?

The thesis defense, also known as thesis presentation or disputation in certain countries, signifies what is often the last and final part of your thesis journey. This is your moment to shine, where you are the center of the stage, to promote your thesis and discuss your results and your research. To some, this event is stressfull, particularly those who prefer not to speak in front of others (see our guide on public speaking) and for others, it’s an opportunity to finally be able to let the world know what you have been up to for the last few months (for master/bachelor theses) or for the last few years for PhD/doctoral theses work.

So how do we learn how to deliver a good thesis defense?

Learn from the mistakes of others…

Many years ago, when I was still in the early phases of my PhD, one of my academic supervisors, a late Professor of Civil Engineering, suggested that I enroll in a dissertation analysis course. The “course” was comprised of me sitting through several thesis / dissertation defenses and jotting down anything that I could learn from them. This included, how well the PhD candidate defended their thesis, what kind of criticism or points were reoccurring, and any other observations that I had regarding the thesis defense. This proved to be a very valuable exercise. This is an exercise that you can (and perhaps should) undertake yourself, not in a formal “course” setting, but rather by listening in and taking part in other peoples’ public thesis defenses. Although not all thesis defenses are public, most tend to be, and there is a lot that you can learn by observing the defense from the point of view of the audience.

So how do you find a thesis defense to listen in on?

The best case scenario would be to listen to theses defenses delivered by students in the same research area and university, if that’s not possible, a different thesis topic but still fairly tangential to your research area would also be useful. These days (I am writing this guide during the covid pandemic of 2020/2021), it is extremely easy to take part in thesis defenses online via Zoom as they are often publicized in advance and can be found by browsing your universities’ online events calendar.

So what did I learn through the numerous theses that I listened to?

The first thing I noticed that was a recurring theme, a question that seemed to appear in all the theses defenses that I attended, had to do with how the student’s work contributed to their research field. What is special with your research? What new findings have you been able to lay forth; or which previously known findings have you been able to amend? This is the the central point that all of your research enquires revolve around, the raison d’être of your research, what are the contributions that you are bringing, and why should we care?

Of course, the bar is much set much higher for doctoral theses work compared to bachelor and master thesis, but the point still stands. This does not mean that each and every thesis that is published needs to be groundbreaking and ignite a paradigm shift. In fact, most thesis work do not lead to any revolutionary contributions. This point is perhaps best illustrated by satirical web sites such as lolmythesis where students submit their real thesis titles alongside a more comical title in plain English. This gives rise to titles such as this one from Yale University with the plain title “UAV deployment for fine-scale CO2 estimation in a mid-size city” which the author claims could also be titled as “I collected all my data then realized I didn’t record the variables needed for the one thing I promised to do in the title of my thesis”.

Do not stress over the significance of your research contributions, but do be prepared to defend them publicly.

What concrete contributions can you claim came about as a result of you having done this study of yours? If you can not answer that question (or at least explain why why your results were or were not remarkable), then you are out on dangerous water. There is an expectation that these contributions that we bring should actually have some form of substance, which they unfortunately do not always have. The site lolmythesis is a testimony to that, it perfectly encapsulates what it means to publish theses. Here are some more examples to put your mind at ease:

Keeping a strong mind set

The table above reminds us not to take things too seriously. If you feel that your results are underwhelming, you may consider yourself a member of the academic club, everyone tends to produce results at one point in their research career that they themselves consider underwhelming. For the defense however, the key here is not to focus on the results themselves, but rather on the overall arguments and the overarching discussion that surrounds your results and provides a context to your key points. Be ready to defend and explain anomalies in data, or the specific choices that you made with respect to why you chose a specific research method instead of another. The thesis defense should be viewed as an exercise for you to be able to explain your overall argument and show why it is consistent. Remember that the thesis defense does not exist for you to be criticized with regards to other peoples data or research. As long as you have a strong grasp of your own research topic, you should be able to breeze through the defense. You can feel assured that (for most cases) no external expert or review committee will know more about your specific thesis than you do. As long as this disparity in knowledge holds true, it doesn’t matter how much more they know about the overall research field, if you are more knowledgeable of your specific research inquiries and their underlying assumptions.

The second point that I want to highlight is that all of your conclusions should follow from the results that has been presented (which in turn come from the data that you collected, depending on research area). With other words, all of the conclusions that are mentioned should follow logically from the underlying premises. I remember once attending a thesis defense where it was clear that the doctoral student highlighted certain conclusions that had no basis in the person’s data, and that sort of things tends to get highlighted real fast. So you need to be careful about that.

The third point concerns quality. The work must of course be of high quality, this is understood by all, but it also means that the data was gathered properly and that the sources that you cite are relevant and authoritative. Make sure that the image/story that you are presenting during your defense is internally consistent. Thus, even if an opponent has issues with a specific method that you chose, they cannot claim that your research contradicts itself. Apparent contradictions can be very problematic, and if you suspect that there might be a contradiction somewhere in your thesis, you need to be ready to explain that paragraph if asked to.

The last thing I want to mention has to do with the mental state of the one who is presenting. There is no doubt that public speaking is stressfull for a lot of people, and it is therefore extra important to remember to not place to much weight on the matter. It is after all only a speech. You know the topic, why worry, you literally wrote a book on it! As one says in swahili, hakuna matata is an appropriate attitude to have towards the thesis defense. It is important to remember that studies, specifically doctoral studies, are more than just a written dissertation. Instead, it encapsulates the whole process where you gradually learn more about your specific research work. Regardless of whether you achieve a undergraduate, postgraduate or doctoral degree at the end of your research, that degree only symbolizes the start of a learning journey, and not the end. Unlike the common conception, PhD studies shouldn’t be viewed as a dreadful and draining undertaking that finally culminates in this large-scale orgasmic metamorphosis where you are transformed from this lowly caterpillar to become a fully-feathered and competent butterfly.

The list below contains a few links to real examples of theses defenses. Do check out the presentation by Dr. Ben Conrad which is really good example of a thesis defense done right, it manages to be informative, to the point as well as engaging the audience and the material.
