Give priority to praise in front of the public. Praise sports if you don't get good grades. If sports are not good enough, praise literature and art, and then don't praise good people and good deeds. This is a problem. Students talk to their parents in private. We will hold a United, harmonious and successful parent-teacher conference. In this way, students are satisfied, parents are satisfied, schools are satisfied, and their educational and teaching achievements are also displayed. Private communication also solved some problems.
