1. The importance of the defense

The disputation is more than just a formal requirement. It is an opportunity to present and defend your research findings and to engage in academic discourse. It is not only about the pure reproduction of your work, but also about the ability to answer critical questions, discuss alternative perspectives and demonstrate the relevance of your research.

2. Preparation: The be-all and end-all of success

Thorough preparation is the key to a successful disputation. Start early and proceed systematically:

  • In-depth knowledge of your own work: read your dissertation thoroughly several times. Pay attention not only to the content, but also to the structure, the argumentation and the methods used.
  • Examine the reviews: Analyze the expert opinions carefully. Identify points of criticism, open questions and suggestions. Prepare convincing answers and explanations.
  • Research relevant literature: Update your knowledge and research current research findings that can support or supplement your argument.
  • Anticipate possible questions: Put yourself in the role of the examiner and think of possible questions. Make a note of valid answers and practise formulating them.
  • Practice your presentation: Rehearse your presentation several times in front of an audience (e.g. fellow students, supervisors). Pay attention to your body language, your voice and your time management.

3. The course of the disputation

The disputation usually follows a fixed procedure:

  • Presentation: you present your research results in a short talk (approx. 20-30 minutes).
  • Questions and discussion: The examiners will ask you questions about your work. You answer these and discuss the various aspects of your research.
  • Examiner consultation: The examiners consult with each other and make a decision on the outcome of the disputation.

4. Tips for a convincing presentation

  • Structure: Structure your presentation clearly and comprehensibly. Start with a short introduction, present your research question and your methodology, present your results and summarize your most important findings.
  • Visualization: Use meaningful visualizations (e.g. graphs, tables, images) to support your statements and facilitate understanding.
  • Language: Use precise and scientific language. Avoid colloquial language and technical jargon.
  • Body language: Make sure your body language is open and confident. Maintain eye contact with the examiners and avoid nervousness.

5. Confident appearance in the discussion

  • Active listening: Listen carefully to the examiners' questions and ask questions if necessary to avoid misunderstandings.
  • Objective answers: Answer the questions objectively and well-founded. Remain calm and composed, even if you are confronted with critical objections.
  • Argumentation: Justify your answers with sound arguments and refer to your research findings and the relevant literature.
  • Willingness to discuss: Show a willingness to discuss and accept constructive criticism. Admit mistakes if you have made any and show a willingness to learn.

6. Ghostwriting as support in advance

Professional ghostwriting can offer you valuable support in the run-up to the defense. Ghostwriters can help you:

  • Optimizing the dissertation: checking the structure, argumentation and linguistic quality.
  • Creation of presentations: Designing appealing and informative presentations.
  • Preparing for the defense: creating question-and-answer catalogs and practicing the presentation.

Conclusion

With thorough preparation, a convincing presentation and a confident demeanor in the discussion, you can successfully defend your dissertation. Use the tips and strategies in this guide and go into the defense with confidence.
