Adolescent girls are more likely to feel supported by their parents, teachers, and administrators.

Adolescent girls are more likely to feel supported by their parents, teachers, and administrators. Boys tend to do less homework, watch more TV, and read fewer books.
Much more research has been conducted on why adolescent girls do less well than adolescent boys in math and science than on why boys generally do worse than girls on virtually every other measure of academic achievement. What hypotheses would you propose to explain why boys generally do worse than girls academically, from grade school through emerging adulthood? Do you think gender stereotypes or roles come into play?
