There is a solution to my problem. I need to kick students out of class. It's pretty simple. I just write them up (and excessive talking is a valid reason), and poof, they're gone for two days.
I have done this. I've given three students the boot--one Tuesday, one Wednesday, and one today. And while this does help a bit, it isn't having the impact I would like. I'm still dealing with all the talking.
So, I stare at the classes. And I try to narrow down my choices. Sure, I could boot five at a time, but that seems rather excessive. I don't want to end up with writer's cramp. It's just so hard to choose.
