To evaluate the teaching quality of college teachers, we should consider the contribution of teaching to students' future adaptation to social development. Therefore, the evaluation of college teachers' teaching quality should not only consider the teaching quality of a class and the stability of long-term teaching, but also pay attention to the evaluation of teachers' teaching ideas. Based on this, suggestions are put forward to improve the evaluation of classroom teaching quality. The study found that how to scientifically design the evaluation indicators of classroom teaching quality, reduce the incompleteness and subjectivity of the evaluation, and improve the incentive mechanism of teachers' teaching are the key to the fair and objective evaluation of teachers' classroom teaching quality.
