tricky

The hardest part of teaching my Bio 101 labs?

-3 Hours on my feet with no chance to go pee!
-Getting them into groups of five. If we move to a different room it's easy because they self-sort. If we're staying in the same room and they're already seated, it's like pulling teeth. I assign groups, they grumble. I tell them to arrange their own groups and they look at me blankly and don't move. Argh.
-Trying to foresee what questions and problems they will have with the material so that I can answer them. I'm about 50/50 on this. If I don't know the answer, we go look it up together.
-Judging how long the whole lab will take. Yesterday ran surprisingly quick and my kids were all sitting around bored waiting for the time I had assigned to do review. Some of the students had left the room to take a break though, so I couldn't just start without them. At least I know for this morning's class.
-The slide projector didn't have slides in it and I hate using the computer to do the slides at the end because someone always screws up the slideshow, and then I look like an idiot.

Aside from that, things are going pretty well. My students respect me and seem to like me. Nothing has gone terribly awry. I've got probably 90% of their names down. Also, they seem to be learning. Which is the most important thing.
