The math teacher in the video below is the kind of teacher who knows how to establish authority, set boundaries and keep his students under control. He is seen as one of the toughest and most respected teachers in school. His students don’t see him as a friend, but that’s fine, because this teacher is not looking to make any friends among his students. He says his job in class is not to entertain his students, but to make sure they learn from him. But there is something about this teacher that his students don’t know and which will make them see him in a whole new light.
