At the school I am at (and I am prepared for a great debate here) they take away "fun" classes like PE and art if students misbehave. When I first started I thought it was ridiculous, and that the kids should have their fun time, but I didn't say anything and kept my eyes open to see how it worked before complaining. (If only our subs, parents, and student teachers behaved this way!!!) This system actually works incredibly well. I have a low incidence of bad behaviors that warrent this punishment, and I use it as little as possible because I feel that the kids should have this time to play or create. You also need the cooperation of that particular teacher. Ours allows it and takes citizenship points from the kids because they are "late" or "tardy". Kids can also earn back their gyms and I never take an entire gym unless the kid was really bad. Usually they just miss the first 15 minutes or so. Taking recess doesn't work because the kids rarely go out anyway, (between cold weather and a bad neighborhood I've only seen them go out maybe 3 times in about a month and a half). I've also threatened the "if you don't start behaving you'll be eating lunch with me!" bit, but by the enthusiastic response I got, I know that this should be saved as a reward, not a punishment. Maybe your kids think of it the same way. I like the star chart, I am going to try implementing that in my class on top of treats on good behavior days. (My kids have only ever once earned a good behavior day treat, its too hard for them to be "good" all day, and by good I mean simply not being deafiningly loud in the hallway. Also, I have seen "traffic light" setups that worked pretty good. Each kid gets a red, yellow, and green card or "traffic light." When they are good they are on green, something bad, they go to yellow, hit red, and its time to call parents, take gyms or whatever your consequences are. Just an idea, and not one that I use with this group (they don't need it) but I have seen it used successfully, especially when you have the child themself take their card and change it. That is pretty immediate for them. Also, what are your consequences, I don't see you posting much about them, maybe they are not clearly posted/not clear enough for the kids, and if they are, maybe they aren't harsh enough? Luckily I have the support of my admin, but those are the ideas I've got, hope they help!
