Today I covered a 7th grade "core" class. I had the same group for two periods--one period for English and one period for world history. They were supposed to work quietly. But quiet working for a sub is hard for kids that age. I needed to give them a bit of an incentive.
Some of them just kept talking. So, I wrote their names on the board. It's amazing how well that works. The girl wasn't facing forward, but her neighbors helpfully pointed out that I had listed her. So, she turned around and stopped talking. That's all I wanted.
6th period I did the same. I only had to list two students to get the whole class to stop talking and get to work. I intended to erase the girls' names after class and leave it at that.
The teacher I was covering was on a field trip. I talked to her before school. So, I shouldn't have been surprised that she arrived at the end of 6th period. And she immediately noticed the names on the board.
The girls got detention. The rest of the class got a talking to (for too much talking and not following the sub's instructions).
I shouldn't feel guilty. It's not like they didn't deserve a consequence for not behaving as instructed. But I feel a little twinge all the same.
