Abstract: By using the methods of mathematical statistics, interview, questionnaire and literature, this paper comprehensively analyzes the changes of students'physical health, and probes into the relationship between the teaching and evaluation mechanism of physical education and students'physical health. Based on the“three autonomy”teaching model widely implemented in higher education institutions, this paper analyzes the role orientation and interactive relationship between teachers and students, and puts forward the conception of innovative evaluation system. In view of the differences of student groups, this paper focuses on the consistency between teaching objectives and students'learning effectiveness evaluation, in order to build a performance evaluation system that meets the individual needs of students. At the same time, the relevant policy recommendations are put forward to optimize the performance evaluation system of public physical education courses in private colleges and universities.
