To insure that each child has a safe and positive environment at school, teachers should earn their pupils' respect and classroom activities should be oriented to helping each child succeed. Three key phrases reinforce the expectation of success. These phrases, which teacher and pupils should understand and remember, are: (1) It is O.K. to make a mistake; (2) You don't have to know everything today; and (3) It is intelligent to ask for help. Teachers should regard discipline as a means of teaching and reinforcing appropriate behaviors. Introduction of a "power chair" in which children can seat themselves when they feel they are losing control is one technique teachers can use that does not embarrass or humiliate students. Teachers spend a great deal of time trying to solve disputes between children or figure out what really happened in an altercation. Instead of doing these things, teachers can wait until the children are calm and then ask them to talk with each other privately about the problem with a view toward obtaining one story that is agreed upon by both children. As a result of such collaboration, the children may fight again, work the problem out, or realize how silly their argument or problem was. (RH)
