It's not gender: it's cultural

''
There's no real difference between the scores of U.S. boys and girls on common math tests, according to a massive new study.
...
Nearly 20 years ago, a large-scale study led by psychologist Janet Hyde of the University of Wisconsin, Madison, found a "trivial" gap in math test scores between boys and girls in elementary and middle school. But it did suggest that boys were better at solving more complex problems by the time they got to high school.

Among students with the highest test scores, the team did find that white boys outnumbered white girls by about two to one. Among Asians, however, that result was nearly reversed. Hyde says that suggests that cultural and social factors, not gender alone, influence how well students perform on tests.

The study's most disturbing finding, the authors say, is that neither boys nor girls get many tough math questions on state tests now required to measure a school district's progress under the 2002 federal No Child Left Behind law.
