From the perspective of teaching people, it is a way of doing things and an educational model;

From the perspective of the educated, it is a kind of restriction, helplessness and incomprehension;

To put it simply, this educational model is very common. It is this "education" and "education" model that lacks communication and understanding that makes many people lose their creativity and bury their rare talents. Of course, the teacher who hits people has a good starting point, and he hopes to shape his students into socially recognized public talents.

Don't be confused, you are right, but you can do better. So is your math teacher, except that he can change the way of communication with each other. What is wrong is only social tradition. (Of course, some abusive teachers or some stubborn students are not excluded. )
