How do you keep certain charismatic students from becoming too much the center of attention? As I come to the end of my first year, I realize that I can name a student or two in each of my classes who gets an improportionate amount of attention from me and from the class. They aren't misbehaving kids or academically needy kids-- they're the ones who are the unofficial "class clowns" and whose antics, while often harmless in themselves, end up making them the continual focus. The thing is, they make the class lively-- the class enjoys their involvement, be it reading or acting in a funny voice, asking unrelated but clever questions, or making me and the students laugh. I really like them all and thought I had good relationships with them, but I'm beginning to feel like the classes have become a performance venue for them! On the occasions where they've crossed the line and been asked to leave the room (or when they're absent), the class has had an empty, dull feeling. It's as if I've relied on them to make class interesting! Any tips?
