Before talking to the teacher, ask your daughter for concrete examples of what this teacher is saying in the classroom that upsets her. It would be a good idea to talk to the parents of other students in the class to find out what their children's reactions are to this teacher. A personal observation of a class will also give you a better idea of how this teacher deals with the children.
When you talk to the teacher, explain that your child is upset by how the teacher speaks to the class. Give examples of hurtful comments. Ask the teacher to tell you how this situation can be turned around in order to rebuild your child's self-esteem. If other parents feel the same way, ask them to accompany you to a meeting with the teacher. The less emotional you are in talking to the teacher, the greater the chance you will have of convincing the teacher some changes are necessary in the classroom. If you get nowhere in convincing the teacher, don't delay in taking this matter to the principal.
Besides working to improve the school situation, you and other members of your family need to help your child rebuild her self-esteem. Talk to her each day about all the good things that happen at school so she won't just focus on the teacher's attitude.
