I tested in all my classes today. I re-remembered (?) a strategy I've used before for particularly chatty/social classes - the ones that take about 5 minutes to settle down to start a test. I stand at the door and hand them the tests as they enter the room. That way, they immediately put their stuff away and get to work, and I don't have to "shhhh, shhhh" them at all. Note to self - don't forget this strategy. Note-note to self - who are you kidding.
I also noticed yesterday that my precalculus classes were all stressed out because I was going to make them remember trig sum/difference/double/half formulas. So I pulled out another trick today. I "sold" them a formula sheet for one point off their exam (out of 30 points). If they chose not to use it, I added a bonus point to their exam. Sheesh. I hope it worked for some of the kiddies.
I again differentiated my calculus exams. They're onto me now, though. As I'm handing them out, they all (the upper level ones) pipe up with, "are there different versions?", and they watch how and to whom I pass out what, and I don't even say anything, and then they answer themselves with, "yea, different versions."
Okay, now I get to grade the things. Yay, grading.
