Graduation thesis defense is an important form of organized, prepared, planned and evaluated papers.
In order to do a good job in the defense of graduation thesis, the school, the defense Committee and the respondent (the author who wrote the graduation thesis) should make full preparations before the defense meeting. At the defense meeting, the examiner should try his best to find out whether the level shown in the paper is true or not. Students should not only prove that their arguments are right, but also prove that the teacher is wrong.
Its main purpose is to cultivate students' ability to comprehensively apply the knowledge and skills they have learned, integrate theory with practice, and independently analyze and solve practical problems, so that students can engage in their professional work and carry out relevant basic training.
