The Intro Physics II final exam was this week. The signs were all there.
1. It was a summer class. Therefore a fairly high proportion of the students were taking it again after having failed it previously.
2. The class switched professors two weeks before the final. The first professor is a skilled scientist but, well, not necessarily as gifted in passing his skills to his students.
3. The second professor made the final exam from scratch.
I just finished grading three problems worth of the final exam (the other two TAs are taking care of the rest), and I think the exam can be safely described as a debacle. It was a disaster. The scores haven’t been tallied up yet, but I think there’s a good chance the mean score will be within one standard deviation of zero. And, I dunno, about 4 or 5 standard deviations away from 100.
Either everyone is going to fail this class, or the curve for the final will have to be so colossal that the final exam will do nothing more than add a tiny bit of variance in the grade distribution.
Here’s a video representation of the final. You’ll also probably learn more about Newton’s first law from the video than the students did from the class.
Ladies and gentlemen, don’t take summer classes unless you have no other option. Just don’t.
