I'm currently teaching a rowdy group of 8th grade math students for a double period of algebra. There are 25 kids, and they are all very talkative. About 7-8 have IEPs, but there is no in class support. It's very rough. I was observed in this class, and was essentially told I sucked. I have trouble getting there attention when they are working in groups or something and I need them to focus at the front of the room. I was told that until I find my "teacher's voice", I won't be successful. I don't think I can do that though. I am not a loud person at all. My voice is typically very mellow, and I have to really strain to make it louder (and then I can barely talk at all after that). Does anyone have any different suggestions for getting the attention of the class after they work in groups? I was thinking of bringing a small horn in, telling them that it's a magic horn, and that when I honk it twice and say "Class, class", they must respond with "Yes, yes". After a while, they could start to use the horn when they want to speak. I am just worried this could backfire big time on me. Has anyone else tried any similar technique because their voice is not so loud? Any ideas?
