The thesis presentation typically begins with the candidate's summary of the project. What do you think you accomplished with your thesis, and what do you think its significance is? Summarize the initial steps that led to the thesis, such as (1) what motivated your interest in this general area and (2) why do you think the particular problem is significant? Present a clear and brief overview of the thesis as a whole. Conclude by emphasizing the particular contributions and insights your thesis offers to the field of study.
After your opening remarks, focus on specific details. Don't go over each chapter verbatim. There is not time to do so, and the committee has already the thesis. This part of the presentation gives you the opportunity to emphasize certain aspects of the thesis that you think are particularly valuable. Take time in your preparation to outline the points you would like to discuss. Practice summarizing each of these in clear and articulate ways. Another step in the preparation process is to reread the thesis. Anticipate the types of questions the committee members will ask. They will focus on things that interest them. Take into consideration the background of each committee member, and be ready to respond to their questions.
Conclude your presentation by reflecting on future research and professional goals. If your career path is research and academically oriented, the committee will want to know what direction your research may take. A thesis project will leave you with more questions than it answers. Certain unresolved questions will interest you more than others. Be prepared to explain different areas you would like to pursue. If you are more interested in a professional career outside the academy, plan out a career trajectory. Emphasize how the thesis is a good preparation for your career goals.
