I substitute teach for middle school and high school quite a bit, and if the students have classwork I find that it is far less painful to let them work on it together rather than silently. Unfortunately, and this is especially true for middle school, the students don't seem to have any volume between silent and ridiculously and disruptively loud! Is this normal? Is there a way to get students to talk quietly to each other? Asking them to whisper doesn't even register. I've noticed that not letting them move from their assigned seat helps with other behavior issues, but not the volume!
