Whenever I substitute middle school, and sometimes high school, I sometimes get classes that just seem to want to talk and not do anything. I try to be firm, not yell at them, and tell them I don't want anyone to talk while they do their work, but it seems like they don't care. For example here's what happened yesterday. I explained to the 7th graders what they needed to do for their assignment and said the assignment is to be done by you only and that I don't want anyone talking while you do your work. (My experience is when students talk, they're not going to get their work done because they're busy discussing things that aren't part of the assignment) Several times the students kept on talking and I said that I wanted everyone to not talk, yet they did that anyway. How am I supposed to handle the situation? What would you have done? Obviously I could have written names down for the students who continued to talk. I'm also guessing the students kept on talking because I wasn't the regular teacher and I'm not going to see them again the next day, the next week, etc., so they could have cared less.
