Do any of you have trouble with classroom discipline? I have had to ask students to leave my classroom twice in the last two weeks, and tell a third if he didn't stop the argumentative attitude he would have to leave my classroom. Two of the students were 35+. The third was only 18. I expect more of my students than that. I teach developmental English and Reading. I have taught this before and only ever had to make one other student leave my classroom. She had emotional issues and upon returning to my class she requested assistance in locating community help (mental health services). I am baffled. Has anyone else encountered this? If so, what did you do?
