The conversation kept going as I typed all of this out! Maybe it’s not relevant anymore, but I thought I’d post it anyway.
If you don’t feel comfortable talking with him alone, you don’t have to talk with him alone. You can ask another teacher to be present. Or his guidance counselor. Or, if it’s more serious (or depending on the school or your relationship with the principal), you can have the principle present. Or the parents, since you mentioned you’re meeting with them.
You mentioned he has been a problem from the beginning of the school year. Has it been other instances of him jumping, or yelling, or pointing, or getting very large with his body language? I feel like I’m not understanding the situation.
What have you done or tried before now?
I would start with the least consequential response and work up from there. You only want to do as much as necessary to quell the behavior, and help the student develop habits that will serve him better in the future. (And if there are underlying issues that are causing him to act in these ways, help him address those issues. That doesn’t necessarily mean you are the one he’s working with—if the underlying issue is beyond the scope of your class, it’s probably the role of the guidance counselor.)
I would still recommend talking with him—with another teacher/his guidance counselor/the principal/etc. present—to establish communication between the two of you. If you believe that his behavior will continue to be disruptive, I would then talk him through the progression of consequence that will happen if things continue the same way they have been. First a, then b, then c, etc. That way he knows what will happen, and it’s not a surprise, and it doesn’t feel like something you’re just putting on him. Make it clear that you are on his side, and you will do what you can to help him, but you also cannot continue to have such-and-such behavior happen in the classroom—and that’s why the consequences.
Because I don’t know your classroom setup, it’s hard to think of in-class consequences for the behavior. I don’t think a consequence should just be about punishing someone. I think it should be a natural fallout of the behavior… So, for example, I went to a high school that required teachers give participation points in class (I didn’t and don’t like that system, but that’s another thing entirely). If the student is being continually disruptive, that might count against his participation points for that day. It’s a system that can be handled quietly rather than in front of the class, so you avoid the unpleasantness of a confrontation for both you and the student. But you would need to keep an individual dialogue with the student to let him know how the points fall and why, and I would establish some silent signal so he knows when his behavior is a problem in class—a warning signal, something to remind him before points are taken away and give him a chance to adjust on his own. Or if your school allows this, you might have a silent signal that tells him he needs to take a few minutes outside to cool off and return (you may want to run this idea by your principal, depending on the school). I would still recommend trying to establish a line of dialogue with the student and understanding what’s causing his behavior, at least as much as you can. Because if the behavior is about him being agitated for one reason or another, finding a way to give him time to cool off is probably a more effective strategy that simply docking points. Or if the behavior is about seeking attention or affirmation, then the best strategy would be to find ways of minimizing the response he gets from the unwanted behaviors, and finding ways to give him attention for positive behaviors… Because, again, the goal isn’t only to get him to stop the unwanted behaviors. The goal is to help him develop better habits.
If the issue continues to escalate and you are out of productive ways to deal with the issue within the classroom, then the consequences would fall to the school’s policies on misbehavior—and that will vary school to school. But this would be part of what you lay out to him as the progression of consequences. (And you would give the less severe responses time to work before progressing to something more severe).
(It’s might also be worth considering how to make sure the response is consistent for future students who are disruptive… Not that the response needs to be identical for each case—some responses might be better for some students’ circumstances and not others—it just might be worthwhile to make sure that you can give a response of equal weight for similar situations.)
