Teaching criticism means that teachers objectively describe and evaluate the phenomena and problems existing in teaching, that is, put forward their own views and thoughts. The basic starting point of teachers' teaching evaluation system is "teaching should be student-oriented". For example, as a class teacher, I strengthened my contact with parents of students. Regarding the situation of students, I will visit my family or contact my guardian in time, communicate in time, and jointly do a good job in student education.
