Problems needing attention in students' defense
First, students should bring papers and main reference materials when attending the defense meeting.
At the defense meeting, after the teacher asks questions, students can prepare for a certain period of time and then answer them face to face. In this case, the necessity of bringing papers and main reference materials is self-evident. Bring a pen and notebook, so that you can put in the questions and valuable opinions raised by the main defense teacher.
Second, be confident and don't be nervous.
On the basis of full preparation, there is no need to be nervous and have confidence. It is very important to build confidence and eliminate tension and panic, because excessive tension will make the questions that can be answered impossible. Only if you are confident and calm, your defense will have a good performance. Self-confidence mainly comes from making full preparations in advance.
Third, after listening to the question clearly, think about it before you answer.
When the main defense teacher asks questions, students should concentrate on listening carefully, write down the answers in the notebook, carefully examine the key and essence of the questions raised by the main defense teacher, and avoid rushing to answer without knowing the meaning of the questions.
Fourth, answer questions concisely.
After knowing the exact meaning of the questions raised by the main defense teacher, you should respond in a short time, and confidently state your thoughts in fluent language and positive tone, without hesitation.
