I substitute at a middle school. It's great and I love it, but after COVID, a large amount of the students developed a particularly unruly and disobedient attitude, especially in certain classes where rules are generally more lax. When it's just a student or two, this is fine. I give them a warning, and if it continues, I mark down their behavior for the teacher to deal with. If the behavior is excessively disruptive, I'll send them to the office. It usually doesn't come to that, and it doesn't take long to resolve. What's challenging is when multiple students, or even most of the class, misbehave. If they're all moving around and causing a commotion, it's nearly impossible to get a handle on the situation because they can't hear me as a group, and if I speak to them individually, the behavior only stops in the area I am in, if at all. What could I do in this situation? I can't send them all down, and these students typically don't care what I write about them in the note to the teacher. I'm trying to brainstorm ways to get this to stop more easily. Any suggestions would be greatly appreciated!
