Since everyone was such a big help with my last question , I have another for you guys. I have a BIP (Behavior Intervention Plan) meeting coming up soon for one of my students, and his target behavior is running out of my classroom and to/into someone else's. The behavior specialist asked everyone involved to think of strategies to diminish this behavior, but I'm having a difficult time. He likes to run out of the room, either through the main door or the fire door in our classroom. Neither door can be locked, blocked, or impeded in any way (including doorknob covers). He waits until the adults in the room are either very far away from him or focused on other students to very quietly creep toward a door, and if we don't catch him in time, takes off at full speed toward 1 of 2 classrooms. One has an "alphabet line" that he really likes, and the other is a new teacher's classroom, and he just thinks it's cool that there is a new room with new stuff and new kids. I can't buy the nice alphabet line for my own classroom because it's no longer being made. Social stories aren't an option (his listening comprehension is pretty low, and he doesn't take an interest in stories). Right now, I'm praising him heavily if he stops before he opens the door, and it's working pretty well (incidents have dropped from 8+ per day to 1-2). Does anyone have other ideas? I know this is a really common problem, but I've never run into anyone who could stop it.
