I have a student in my room who is very disruptive. On top of that, he's confrontational, argumentative, and lacks the ability to take responsibility for his actions. When asked to stop doing something disruptive (repeatedly singing the jingle for an applesauce commercial, for example), he argues that he wasn't doing anything wrong, says that I'm not being fair, and then escalates the behaviour. This is an all day (or period) every day kind of thing. I looked in his file and this is not new - it's something that has been going on for years. And, yes, he has been evaluated. It all came to a head the day before yesterday when he was continuously disruptive. After numerous (too many, even) warnings, I told him that I needed him to work in the hall. He refused. An "arguement" ensued (me repeating that he needed to work in the hall and the reasons why, him coming up with every excuse in the book as to why it was unfair, he didn't do anything wrong, etc.). To make a long story short, putting him in the hall didn't stop the behaviour and when I called the office to let them know he would be on his way, he picked up a chair and threw it against the wall, screaming bloody murder. Someone in the office came to get him. I'm at the point where I don't know what to do with the situation. I've tried all of the suggestions in his file to no success. Yesterday was touchy because I didn't know how to react to him. I was able to reflect and this is what I've come up with. Any advice, comments or suggestions would be greatly appreciated: I've noticed that his behaviours escalate when he has an audience. Talking to him one on one is...not great, but ok. So, I've decided to ignore all but his major behaviours. Today, for example, he talked, sang, made noise, tried to have me catch him using his cell phone, etc. And I ignored them. He was given a warning for yelling "I love b**bies" during my instruction and he was asked to stay in his seat twice and to lower his voice 3 times. For the other incidents, I focused more on his peers. When he did something distracting and his friend turned around to watch, I reminded his friend to stay on task. When he made a noise another student tried to copy him, I gave the other student a warning. When he told inappropriate jokes and the students laughed, I told them they needed to quiet down. By the end of the class, for the most part, the others were staying on task and he was alone at the back of the room making weird noises for no one but himself. At the end of class, I pulled him aside and told him that he was being placed on the next level of our school's behaviour policy for his disruptive behaviours. He nodded, said ok, and left the room. My hope is that if I'm consistent enough with the other students, they will quickly lose interest in his actions, thereby getting rid of his audience and, hopefully, his behaviours will simmer down. What do you guys think? I really am at the end of my rope here.
