Children with bad grades but willing to learn, or even if they are unwilling to learn but have good conduct, even if they are a little playful and naughty, the teacher will not give up, and will often invest more energy than other students, but the real bad children, the teacher will not only give up, but even unwilling to provoke, all he can sit on is to stabilize these children, not to intensify the conflict, so that other children have a good teaching environment.
Teachers are able to establish authority among students, and students are able to embody "fear" of teachers because they are bound by basic rules of conduct, have basic values, and at least have a good home education. Teachers are also human beings, and they also have their own preferences, there are so many children in a class, there will always be children who like it more, after all, children who are smart and lively, respect teachers, and are willing to help their classmates, that teacher doesn't like it.
And those children who not only do not study, but also affect other children's learning, and even have bad behaviors, why should teachers like them.
Behind every bear child, or there is a pair of bear parents, or parents are no longer around to discipline, for the care of these children, it is difficult to get positive feedback from parents and children, and even can not appreciate it at all, if a strict teacher to discipline, not only will make the child antagonistic, or even more confrontation to show personality, but also can not be understood by parents, and even cause complaints, affecting their own careers.
Many people think that children in junior high school are difficult to teach, because many children are in the rebellious period, but in fact, the most difficult is vocational high technical schools, one or two children are bad children, and the teacher's discipline has a certain deterrent effect, but if more than half of the children are the biggest, it is difficult for the teacher to control, and the key is not to have major problems in the Buddhist system. As for teaching, that's it, I really expect most children to learn.
