1. Self-feeling: I mainly record what I feel most, so as to grasp the main lessons, summarize and find out the regular things. Such as whether the teaching design is reasonable, whether the teaching purpose is objective, and whether the key and difficult points are accurately grasped.
2. Student information feedback: mainly refers to the change of students' expression, whether they are focused, whether their attention is concentrated and stable, whether the classroom atmosphere is active and harmonious, whether the emotional communication between teachers and students is harmonious and normal, whether students speak actively, and whether the teaching effect is satisfactory.
3. Comments on lectures: mainly listening to the opinions of the teachers, instructors and students.
