I like that this article puts the data on the table. I have no idea about what is the exact mechanism for the issue, but as the article notes, girls and boys have slightly different intellects. Furthermore, the eyes-of-the-beholder (teachers) regard them as slightly different creatures as well. And, it wouldn't surprise me if girls in general are nicer to the teachers; while teenager boys feel the pressure to act like he-goats to impress the girls and earn the respect of their peers and adults; and "because kids," their efforts cause the opposite effect in teachers.
