The correct way to communicate is to point out the teacher's mistakes, but you can't directly point out the teacher's mistakes in person, otherwise it will bring very embarrassing emotions to the teacher. If parents criticize the teacher's mistakes in front of everyone, the teacher may think that parents have no respect for themselves. And at this time, the teacher will feel that his face can't be saved, and the teacher may not necessarily admit that his behavior is wrong. In this way, teachers will have targeted emotions towards children, and teachers will not change their behavior in the future.
Rational solution Therefore, really smart parents will choose to have a good talk with their teachers in private, whether through social accounts or through private communication, so that teachers can understand what problems exist in their behavior. This kind of communication is very effective, and it is easier for teachers to recognize it. If we find this correct way of communication, I believe the teacher will be able to correct his evil ways.
But some teachers are really stubborn. These teachers will stick to their own education and will not communicate well with their parents. At this time, parents can choose to ask other children's parents about this matter. If all parents think that the teacher's behavior is incorrect, they can choose to report it to the school leaders and let the leaders put pressure on the teachers to change the teacher's problems in this way.
