First, you can talk privately with the class teacher in class. In fact, high school students are under great pressure now. After all, after the second year of high school, it is the third year of high school. Senior three means that you are about to enter the university. If you don't do well in the exam, you probably won't do too well at that time. However, teachers must pay special attention to online classes when they are in Grade Two. After all, online teaching materials will distract children and make them study less seriously. On this basis, teachers still don't understand online courses. That will certainly waste children's time and energy. Many parents leave their mobile phones at home for a day in order to give their children a good online class, but the teacher's behavior is very uncomfortable. In this case, it is recommended to communicate with the class teacher first. If the math teacher is the head teacher, communicate with the head teacher directly. The math teacher is not the head teacher. Please talk to the class teacher first, and let the teacher communicate with the math teacher.
Second, if not, it is ok to communicate with school leaders to clarify the facts. Of course, it still depends on whether the teacher's communication is effective. If so, then we don't have to worry. If not, then we can react with the school. After all, schools also attach great importance to children's learning. If the school teachers don't attend classes well and affect the enrollment rate of the school, the school is definitely unwilling. However, parents are also advised to pay attention to your tone when communicating with teachers. Don't let the teacher think that you owe him or that he owes you. Let the teacher feel respected, starting from the teacher's side and starting from the children's side, and the teacher can accept it.
