• "What theoretical and practical significance does this research have?" - Elaborate separately, be specific about theoretical contributions
• "How does your research differ from existing studies?" - Emphasize innovation points and workload

Category 2: Research Design Questions

• "Why did you choose this research method?" - Explain method and research question alignment
• "How was the sample/data selected?" - Explain source and selection criteria
• "How was the research process designed?" - Describe by timeline or phases

Category 3: Data Analysis Questions

• "What does this data result indicate?" - Objectively state results, do not over-interpret
• "What if results are inconsistent with expectations?" - Acknowledge limitations, explain possible explanations
• "Have you considered other explanations for the data?" - Demonstrate rigorous thinking

Category 4: Innovation Point Questions

• "What are your innovation points?" - State max 2-3, be specific not vague
• "Are innovation points supported by literature?" - Cite support, explain difference from existing research
• "What are the limitations of this research?" - Be honest but explain limitations do not affect core conclusions

Category 5: Future Research Questions

• "What future research directions can be explored?" - Propose 2-3 specific directions
• "If you continued, how would you improve this research?" - Demonstrate extended value of research

General Principles for Answering Questions

• Do not improvise for questions you do not understand, honestly say "I have not deeply studied this question yet"
• Answers should be concise and organized, do not beat around the bush
• If questioned, first acknowledge the legitimacy of the question, then explain your considerations
• Most importantly, be very familiar with your thesis content and research process

Frequently asked questions

What if professor asks questions completely outside the thesis scope?

Honestly state this direction is not closely related to this research, but it is better to make some extended answers based on your understanding if possible. The key is demonstrating thinking ability, not avoiding questions.

What if professor questions a thesis flaw?

First acknowledge the issue exists, then explain whether it was addressed in the thesis or how it could be improved later. Defense is not a trial, it is demonstrating your academic attitude.

What if I completely cannot answer?

Honestly state this question requires further research, do not improvise answers on the spot. Defense professors can usually identify improvised answers, and honesty often leaves a better impression.
