A recent National Bureau of Economic Research Working Paper on gender and academic achievement at the U.S. Air Force Academy, however, finds that the importance of female mentors may be even more powerful than previously thought. The study, by University of California-Davis economists Scott Carrell and Marianne Page and their colleague James West at the Air Force Academy, finds that replacing a male instructor with a female one has such a strong effect on female achievement as to erase the gender gap entirely...
The authors found that women on average obtain scores that are 0.15 grade points lower (half the difference between an A and an A-) than their male classmates, even after accounting for students' SAT scores. The gap in performance was widest for women taught by men. When a female instructor was put at the front of the classroom, nearly two-thirds of the grade point gender gap evaporated. (It was also the case that men performed better when taught by other men, but the difference was far less substantial.) The authors persuasively demonstrate that the overall male-female performance difference is due in large part to the fact that men dominate the Air Force Academy science faculty (as is the case in most schools), with only 23 percent of courses taught by women.
It would be interesting to learn how valid the study is. This part is interesting as well:
Yet the authors found that, while female students perform better on average in classes taught by female professors, there are some male professors under whom there's no achievement gap between male and female students (and also some female professors for whom the gender gap is as big as that of some of their male colleagues). So some men are very good at mentoring women, just not nearly enough of them.
Interesting article, but seemingly inconclusive as to the "solution". I got a little concerned, though, upon reading about "making men into more women-friendly bosses and teachers". Why is this always a one-way street? Let's go from math and science a moment to the entire university campus and student body, where women significantly outnumber men in admissions and degrees earned. Why do we not hear of making universities more men-friendly? Again, why the one-way street?
