This paper expounds the gains and losses of this course from the aspects of teaching objectives, teaching contents, teaching methods and means, teaching structure, students' participation and learning effect. It is necessary to have both opinions and evidence to reflect the "quality" of this class, and generally do not make a comprehensive evaluation in order to highlight the key points.

Instead, choose more meaningful and typical aspects to comment. The evaluation should also point out alternative improvement practices from the perspective of recommendations.

It is very important to carry out classroom discussion activities through attending classes to improve and promote teachers' professional level and personal quality. How to write a good lecture record is not only the first-hand material of class evaluation, but also the basis of teaching research.

Write lecture records from the following aspects:

First, remember the time allocation. In the process of listening to the class, how long each part of the teaching steps took should be recorded. Because the time record can be used to judge whether the time allocation of this class is reasonable, whether it can highlight the key teaching contents and complete the teaching objectives.

Second, remember the language evaluation. Explain whether the language is standardized, coherent, vivid and vivid, and whether there is any obvious slip of the tongue; Whether the classroom immediate evaluation is in place in time, whether it can arouse students' practical enthusiasm and carry out effective ideological and moral education for students in combination with reality.

Third, remember the activities of teachers and students. How teachers participate in teaching activities, effectively solve classroom accidents and solve students' problems in practice in time can not only reflect teachers' ability to control the classroom and give full play to teachers' leading role, but also enable students to effectively participate in classroom learning and activities and always be in the state of active learning.

Whether the teacher's demonstration is correct and reasonable is the key to the success or failure of a class. Therefore, we must learn from each other's strengths and make good teaching records.

Fourth, remember to sort out the teaching links. Remember all the teaching links in the class. How do teachers organize all parts of teaching, introduce new lessons, review and consolidate, practice in groups after completing new teaching, and let students master skills step by step at several levels. Can we choose and determine teaching methods around students' autonomy, cooperation, inquiry and acceptance?

Fifth, remember the teaching organization. Seriously record how lecturers organize teaching, the form of group rotation, the number of times students practice, how to introduce new courses, and how to undertake the transition between different parts of teaching content. The choice of teaching methods must have a clear theme, conform to the teaching materials and students' reality, and ensure the integrity and fluency of the teaching process of a class. The design of each teaching link must focus on the overall teaching goal, which is simple and practical.
