I’ll never forget the book I read back in college called, Discipline Without Tears, by Dr. Rudolf Dreikurs. “It provides a clear, constructive outline of his proven strategies for dealing with a wide range of childhood misbehaviors. Believing that children are social beings who want to belong, Dreikurs stresses encouragement, cooperation, and firm control in a democratic alliance of parents, teachers and children.” Dreiker’s book has had a long lasting effect on me and my discipline techniques were based on what he said and I would highly recommend reading it.
Be fair, set up consequences that fit the crime so to speak. Make sure that all of the children are treated the same way. One rule that I’ve found to be very effective is 3 strikes and you’re out. If you have to talk to a child 3 times during one period, there is a consequence, if he/she misses 3 home works in a semester, there is a consequence, if he or she is disrespectful, or bothers another child, there is a consequence, and so on. Be consistent, don’t give them chance after chance, they know the rules and if they choose not to follow them, it is their decision.
