The Gender Gap, Other Stuff

I forgot to tell this story in the video:
While proctoring one of the exams I told the kids I would give them a freebie. Several looked up and I said, "the answer to number 13 is 'tarantula.'" I love watching realization dawn. The first beams of light start with the smartest students then slowly the rest of the class stops looking to see what question number 13 is and figure out why others are laughing.
