So far this year has been going well, with the exception of 1 class. They are a very immature group of young men who tend to be very talkative and energetic during my last period class. What normally happens is one student will say something and then it will ignite a flurry of comments and responses. I won't talk over them, and it never takes more than a few seconds for them to quiet down, but the talking will start again almost immediately. I have tried separating them, sending them out in the hall, talking to their parents, making them stay after school, etc, and they still continue to talk. I am making a new seating chart, and considering putting them all together as a sort of reality check. If they are disruptive, I'll warn them once and send them to work in the hallway. If they miss instruction because they aren't in the classroom, I'm hoping they will figure out that they need to shape up. At the very least, I'm hoping it will allow me to teach without constant disruptions. Any thoughts?
