I believe it’s because there are so few men left in the schools teaching these days. The female teachers are left to interpret the boys as dysfunctional and having problems because they aren’t behaving like little girls.
True enough. It's especially true at the elementary level. We seem to have quite a few men teaching at the high school, or even at the middle school level in our district. Once the boys get past elementary school, they usually have at least some male teachers, especially if they are in higher level math and physical science classes. Unfortunately, many of the good men teachers end up in administrative positions, and are lost from the classroom after a few years.
Our older son's AP calculus teacher is retiring after this year, and his honors chemistry teacher from last year is now the assistant principal. Our son has a lot of respect for both of them, and and we hope that he'll have a decent teacher in his senior year for calc II. Unfortunately, his younger brother will miss out on both of these excellent teachers. They both prefer men teachers in most instances. Part of it is rapport and male-friendly teaching style, and part of it is avoidance of some of the feminist bias in how content is presented.
