I'm currently substituting and working towards my teaching credential. I thought I'd be comfortable with a using a discipline plan. This week I subbed for a 6th grade class. There were two students who kept taking offense really easily and would get confrontational. One particular phrase I heard in class was "Stop looking at me. I'll slap you silly." This was directed to another student, not me. Or if someone accidently bumped their desk they would jump up in that persons face. I followed the teachers behavior plan, writing names on the board, checks, and removing the students to the back of the class. I had them look at the rules and tell me which they had broken but they really didn't seem to care. The class was great but for these two. I'm wondering what is the best practice in these situations. I'd like to be able to nip this in the bud early when I get my own class and the plan I used this week didn't seem to have much effect.
