There is a group of three students that make other students feel like they can't speak up or they will be made fun of, and other students do not speak up because those three are a constant distraction in class. How can a teacher change that environment so that these three students do not intimidate the rest of the class anymore?
I have recently discovered that it may seem mean when you are the student being called on, but having students raise their hands makes students feel as though they shouldn't answer.
I agree, the ring leader is removed and the issue will most likely stop.
