In the eyes of these parents, the teacher has the responsibility to teach the children well when they are sent to them. Once a child can't teach well, he will put all the responsibility on the teacher.
The teacher can't guarantee the child's good behavior.
The first duty of a teacher is to teach, and then to educate people. They are more responsible for imparting knowledge to students every day, rather than spending more time teaching children how to behave. When something happens to a child, parents like to say, "Didn't your teacher teach you at school?" But these parents never ask, "Have you ever taught these children?" Many parents think that teachers will discipline their children when they are sent to school, and then they will ignore them. Children may meet countless teachers when they go to school, but there is only one parent. It is what parents should do to educate their children to keep good conduct. What kind of parents, what kind of children. Don't be stereotyped, but expect others to teach your children in another way.
Second, teachers can't give children good habits.
It is not teachers or others who live with children, but parents themselves. Children will learn a lot from their parents, both good and bad. So when you can't figure out why children have so many bad habits, take a good look at yourself first, and maybe you will find the root cause!
