Who’s better at math? Subtract gender

Emily Johns:

Scores from 7 million students nationwide show that girls and boys do equally well on tests. But Minnesota’s high school girls still lag.
When it comes to math scores, high school girls are measuring up, reports a national study challenging the persistent notion that boys are naturally better with numbers.
The University of Wisconsin-Madison study released Thursday in the journal Science reported that, overall, U.S. girls and boys got equal math scores, from second through 11th grades. The results of the study, the largest of its kind, represented marked improvement over a 1990 study showing measurable differences in complex problem-solving, starting in high school.
