Probably. I'd imagine that male teachers have policies that jive better with male students, especially the more energetic/unruly ones.

For example, my homeroom 6th grade drill sergeant-esque teacher would order us to do push-ups when we acted up, rather than docking our grades. That kind of pseudo-military style punishment fits boys better, I think. Gets the point across without feeling emasculating or overly punitive.

Was that population that big to begin with? Most of my male teachers in highschool were actually just wanabe-sport coaches. My male history teacher/basketball coach just played movies every day.

In my middle-school days, there were some very sharp guys teaching in part because of the Vietnam draft. (No, I'm not young anymore.) At my high school (all boys, Catholic), the coaches had to teach real subjects: Algebra I, Trig, Plane Geometry, Biology, Chemistry. Now, one of the wrestling coaches sent a classmate of mine hurrying to the other class with his statement that a milligram was one million grams, but most of them seemed to do OK. Not all of the other male teachers were in orders, either, and most of them, lay or religious, ranged from adequate to good.

I guess it depends on when and where you went to school. I had hardly any male teachers and I am a student of the 90s. In Australia less than 30% of all teachers are male, divorce rates are very high and single parenting is increasing. I think young boys really lack male role models in society today.
