We whiteboarded some problems on lenses today. Students asked good questions, and they seem to be in a good place with the ray model of light.
And my students wanted to see how happy am I, using the Oxford Happiness Questionnaire. The other class had a student who was sure he was cooked because he was upset his ray diagram, which was not drawn very well, wasn't giving the same answers as his calculations. I gave off grumpy man vibes.
Fair enough. I didn't get enough sleep, and I'm trying to rewrite the best software to use for standards-based grading since I can't use it do privacy laws in my state. Also, copies don't seem to being made in the copy center that they absolutely say we should do all of our copying. It looks like it might now take a month for copies to arrive?
