Day 165: All Boys. Again.
Today I got my class roster for next year's AP Physics C course. It's all boys, again. Although this year I had one girl and 14 boys, the previous two years have been all male. And the year before that was just two girls.
It wasn't always this way. For a number of years, the class ran about 50/50. A significant number of changes have happened (course-wise, teacher-wise, school-wise) since then, so I'm finding it hard to pinpoint any particular variable as the culprit.
