"By zapping the brain during mathematical lessons, scientists have improved students’ numerical skills by a third. Not only did the participants become quicker when calculating figures in their head, they also learned their arithmetic up to five times faster."
"Our study shows that it's not lack of ability or differences in ability that orients females to pursue non-STEM careers, it's the greater likelihood that females with high math ability also have high verbal ability. Because they're good at both, they can consider a wide range of occupations."
So it turns out lady teachers are making little ladies nervous about their abilities in math, probably because the lady teachers are worried about their own math skills, since everyone knows girls are no good at math. But have they done any studies on whether the lady teachers are helping the little girls feel pretty? Because I bet they totally are! Also: Larry Summers was unavailable for comment.
