A provocative question, to be sure. As we all know, females heavily dominate the teaching profession in the elementary grades (over 80% of elementary teachers). Perhaps it is precisely because elementary teachers are mostly female that elementary grades are dominated by the sort of pedagogy and classroom assignments that girls tend to prefer but that boys might not.
After all, we live in a world where males and females have different tastes on average, regardless of how this came about or how desirable it might be. Imagine if the situation were reversed. Imagine that 80+ percent of elementary teachers were male, and that they were constantly assigning girls to design football plays or battle plans for assignments putatively related to math or social studies. Would no one raise the complaint that men were being insensitive by assigning so many projects that most girls didn’t actually enjoy or identify with, and that were barely related to any legitimate academic objective in the first place?
Note: I’m not saying that female teachers are inherently more inclined to waste time than male teachers would be. Indeed, the example above assumes that if male teachers were in charge, they might find time-wasting activities of their own. I am suggesting, however, that if there were greater gender balance among teachers, both genders might keep each other in check.
