Evaluation of teaching is an important part of teaching management. There are many details that need to be attached great importance to in order to improve the quality of education. Students' evaluation of teaching is a common practice in higher education. It is necessary to fully explore and analyze how to improve this system, The following is the author's comments after the article "re discussing the students' evaluation of teaching in university classroom teaching", which expresses the author's thoughts based on years of teaching observation and experience.

For the new teachers who are not experienced in teaching or the old teachers who are not serious in teaching, students' evaluation of teaching can play a better role in urging teachers to improve teaching. But for the teachers who have rich teaching experience and the teaching quality has been stable above the excellent level, too much use of the method of students' evaluation of teaching is easy to lead to the phenomenon that some teachers dare not or do not want to make strict requirements on students. At this time, for the performance evaluation of such teachers, it is a feasible teaching management method to dilute students' evaluation of teaching. However, it is easy to lead to teaching management and teaching evaluation rules are not unified and too complex, on the contrary, it is easy to bring new problems and contradictions.

Therefore, relatively speaking, some feasible ways to retain students' teaching evaluation and actively improve students' teaching evaluation are as follows: 1) students' teaching evaluation should be strictly placed before the final examination, especially before they see the final examination results, so as to better avoid the problem that students' teaching evaluation results may not be fair because they know the score. 2) In addition, we can also adopt the method of removing the top ten percent of the highest score and the bottom ten percent of the lowest score when calculating the teaching evaluation score. This method can also better avoid the problem that the strict teaching management of teachers offends a few students or the loose teaching management flatters a few students. 3) Finally, for the teachers whose teaching evaluation has reached the excellent level or above, we should weaken the incentive measures for the differences of these teachers' teaching evaluation, and generally give the same level of teaching performance. We should not highlight the differences too much, and only spur or punish the very few people whose teaching evaluation is really bad, On the one hand, it can constantly improve the teaching enthusiasm and quality of all teachers, and at the same time, it can make everyone feel at ease to carry out their daily teaching without worrying about the gains and losses of teaching evaluation. Excessive teaching evaluation and excessive teaching evaluation, on the contrary, can easily lead to teachers' psychological anxiety or inappropriate teaching practices.

An extended but closely related problem is that teaching management and teaching evaluation need a scientific and standardized management system. In recent years, the implementation of education and teaching management methods, such as the certification system of engineering education represented by the Washington Agreement, has played a very positive role in promoting the improvement of teaching quality in many colleges and universities. However, the teaching management and teaching evaluation methods that are too detailed and too sophisticated are easy to turn the education and teaching activities into factory production line or farm production line. Therefore, everything should not be too extreme, too detailed and too strict, especially the daily management that is too utilitarian and too profit-making is easy to lead to the lack of flexibility of thinking and the lack of interest in teaching activities Improvisation and flexible interaction between teachers and students may lead to deviation from the original intention and purpose of education.

Back to the core topic of this paper, in short, in the daily teaching evaluation and teaching performance appraisal, we should treat all teachers who have stably reached the excellent line or above equally as far as possible (very few excellent teachers can be given special rewards, but in normal circumstances, we should treat all teachers equally as far as possible), Only by properly, reasonably and legally urging or punishing the very few teachers whose teaching evaluation is really bad, can teachers generally have psychological stability in their teaching work, and thus can teachers with different personalities and knowledge structures freely play their unique teaching style and personal charm in teaching, On the contrary, it is conducive to the active classroom teaching and the continuous improvement of teaching quality.
