In order to earn a degree and build an academic career, scholars need to write and defend a dissertation. Preparing for the defence requires considerable effort and careful elaboration of the research results. What should you pay attention to? In this article, we will consider the main factors that affect the success of a dissertation defence.
How to successfully defend a dissertation?
1. The quality of the research
The success of a dissertation defence directly depends on the chosen research topic. It is important that it is original and offers new ideas or scientific approaches. This includes innovative methods, fresh data, or alternative views on already known problems. In addition, the researcher should explain the relevance of the topic, justify its practical application and scientific novelty.
2. Availability of publications
One of the prerequisites for admission to the thesis defence is the availability of scientific publications in professional journals and magazines indexed by Scopus or Web of Science.
This list also includes publications in journals classified in the first and second quartiles (Q1, Q2) according to the SCImago Journal and Country Rank or Journal Citation Reports (except for publications of a state recognised by the Verkhovna Rada of Ukraine as an aggressor state).
Their number varies depending on the field of work and academic degree. Publications serve as proof of the relevance and significance of the research. That is why it is important to take care of their preparation and publication in advance. You can find out more about the role of publications in defending a dissertation in our article on this topic.
In addition, you need to check the availability of all the necessary supporting documents for your dissertation (opponent's feedback, supervisor's opinion, copy of your diploma, etc.).
3. Approval of the dissertation materials
Approbation is a comprehensive expert evaluation of dissertation materials by reputable scientists in the relevant field. Public presentation of the results allows you to get valuable feedback from industry experts, identify possible shortcomings and eliminate them in a timely manner.
For a specialised academic council, approbation is an indicator that the research has passed the stages of independent evaluation and verification, which increases confidence in the results and their scientific value. It is mandatory for applicants for the degree of Doctor of Sciences (Resolution of the Cabinet of Ministers of Ukraine No. 1197).
It is worth noting that despite the absence of a mandatory requirement to approve the materials of the PhD thesis, participation in scientific events (conferences, symposia, etc.) is a significant addition to the applicant's scientific achievements and testifies to the relevance and novelty of the research.
Where you can test your research?
- international conferences;
- All-Ukrainian and regional conferences;
- forums;
- scientific seminars;
- department meetings;
- symposia;
- publications in journals, collections.
4. Visualisation
In the process of preparing for your dissertation defence, you should take the time to create an accompanying presentation. It will help to draw the attention of the audience to the key achievements of the research and demonstrate its results. When creating a presentation, you should take into account a number of recommendations that will help facilitate its perception.
First of all, slides should be informative but not overloaded with text. It is better to use bulleted lists, graphs, and images to visually reinforce your ideas and make the presentation more understandable to the audience. You should also avoid duplicating the information provided by the applicant, as the slides should complement the story, not repeat it.
In addition, it is important to define a clear timing for each slide in order to keep within the allotted time for the presentation (usually 15-20 minutes). This will help you to focus on the main points and not be distracted by secondary details.
5. Prepare answers to your opponents
Questions from opponents are an integral part of the dissertation defence process. An opponent is a researcher who is appointed to evaluate the work of an applicant. Their role is to analyse the thesis in detail and identify its strengths and weaknesses. During the defence, the opponent asks questions, makes comments and suggestions that may relate to both the methodology and the results obtained.
It is worth reading his or her feedback in advance to prepare for possible questions and criticisms. This allows you to respond clearly and reasonably to all comments, as well as demonstrate a deep understanding of the topic and readiness for constructive dialogue.
6. Rehearsal
Rehearsal is an important stage of preparation for the thesis defence, which helps you to speak confidently in front of the committee. By rehearsing in front of friends or colleagues, the applicant receives feedback and identifies weaknesses in his or her presentation.
In addition, such preparation will help you feel more confident and minimise your fear of speaking in front of members of the dissertation committee.
7. Preliminary defence
The preliminary defence of the dissertation allows the applicant to receive feedback from colleagues and the supervisor. In fact, it is a rehearsal that allows you to check the readiness of the work, the structure of the presentation and the skills of the presentation. During the preliminary defence, the researcher presents his or her main results, the purpose, and objectives of the study, and justifies the methodology.
At this stage, all those present can ask questions, provide constructive criticism and share their recommendations. This helps to identify weaknesses in the work that can be corrected before the official defence.
Taking into account all of the above aspects will help you successfully defend your dissertation and make a positive impression on the dissertation council. Remember that thorough preparation and confidence in your knowledge are the keys to success.
