Participation in teaching evaluation on the part of university students has been widely adopted as a method for the improvement of teaching quality. In view of the problems existing in the teaching evaluation with the involvement of university students, with the student assessment questionnaire of a certain university as a reference, the analytic hierarchy process (AHP) has been applied to establish the hierarchical structure of the student evaluation index system. With the weight of each student's teaching evaluation index determined, a quantitative analysis model has been developed based on fuzzy mathematics for student evaluation of teaching. The application results show that the model is practical, effective and easy to handle, with its easy application to computers.
