If a treat, punishment, special activity, or assignment under the teacher's control is promised, follow through. Children with behavior problems distrust even the best excuse a teacher gives. Do not use intimidating actions or statements as a form of behavior control. While young children may respond out of fear, the price of such intimidation is high. The message teachers send by using intimidation tactics is that it's OK to frighten smaller, less physically capable people into submission.
Older students are more apt to become physically aggressive toward a threatening adult.
Deal with noncompliant behavior consistently . Make sure rewards and punishments relate logically to the student's actions. Use punishment as a tool of instruction rather than revenge. Be honest with students. Prepare students in advance for any changes.
