Is the feminization of the education system in the US partially responsible for the increased number of learning disabled boys?

Girls are well-known for being better at school (on average) than boys. They learn to read faster; they appear to be more attentive; they can sit still for longer periods of time.

Boys learning styles are different. They try things out; are more tactile; more active; and have a hard time sitting still.

Obviously, if you want kids to focus on tasks requiring concentration, it is easier for the teachers if they all sit quietly in rows and attend to their work. Kids running around, making noise, just seems chaotic, and no one believes appropriate learning is going on.

So is the increase in diagnosis of things like ADD and other learning disabilities at least somewhat a reflection of the largely feminine educator corps’ desire for quiet classrooms?
