I teach first grade in a large, inner-city school. I have one student in particular (in addition to many other issues) who goes out of his way constantly to terrorize the other children. This boy is virtually uncontrollabe. He is always out of his seat. When at the rug as a whole group, he is up wandering the room. The biggest problem however, is that when he's out of his seat, he terrorizes the others. He throws things at them. He pushes/hits/kicks/jumps on them. He goes through their things and steals their personal property. He yells at and taunts them and teases them loudly. He sprints around the room and jumps off of the furnture. He climbs on desks and chairs. This happens ALL DAY LONG!!! I've done behavior charts. I talk to Mom EVERY DAY on the phone, sometimes in the middle of a lesson. I've sent in numerous office referrals regarding his physical aggression and taunting nature, but my principal has done NOTHING. He's been referred to the school social worker, but she just keeps handing me more behavior charts, that never work. He is COMPLETELY UNAFFECTED by any form of negative or positive reinforcement. He doesn't care if he loses any priveleges. He doesn't care about earning stickers or food or prizes. I've tried praising him for EVERY little thing he does correctly, but it does not improve his behavior. I'm concerned because, when he's up getting into trouble, all the children have their eyes on him, mainly because they feel unsafe. They're afraid he's going to go through their stuff, or even worse, throw something at them or jump on them or God knows what. I've given lessons on ignoring his behavior, but he's unignorable. What do I do????? HELP!
