Gender Math Gap

Are Boys or Girls better at Math?

Many explanations for the gender gap in math skills don't hold up, suggests new research on math skills and gender in 86 countries. Math has traditionally been seen as a man's game, and the statistics often indicate that there are differences between males and females in their math skills, participation in math activities and performance on tests — called the gender gap in math. Some researchers have proposed this gap is natural — that men are just better at math than women — while others say it's a cultural difference, whereby society somehow keeps girls from pursuing or excelling in math (Berenbaum, 2008).

The new research points to culture as the culprit, finding that certain countries showed less of a gap between males and females in math. Specifically, these female-math friendly countries have more gender equality, better teachers and fewer students living in poverty. In many countries, there isn't a gender gap in mathematics performance, the researchers said.

As for the United States, they say the gap has greatly narrowed in recent decades as more females are considered "highly gifted mathematicians" (3 to 1 now, instead of 13 to 1 in the 1970s) and more women are getting graduate degrees in math, though 70 percent are still men.

"This is not a matter of biology: None of our findings suggest that an innate biological difference between the sexes is the primary reason for a gender gap in math performance," study researcher Janet Mertz, of the University of Wisconsin-Madison, said in a statement. The study suggests that "the math-gender gap, where it occurs, is due to sociocultural factors that differ among countries, and that these factors can be changed (Bettinger, 2005)."



Greater variability

Lawrence Summers, then president of Harvard, proposed in 2005 that men are overrepresented in math-based fields (like engineering and physics) because they have more natural variability in their math abilities. This hypothesis suggests that there are more women who are "average" at math and more men who are really good or really bad at math, and these men who are high-ranking outliers would be the ones who end up in these math-based fields (Booth, 2009). The study analyzed data from two international surveys of school mathematics performance, one from 2007, which included fourth- and eighth-graders, and the other from 2009, which included 15-year-olds. The data from 86 countries, including the U.S., Belgium, England, Hong Kong and New Zealand, shows greater variability in male math talent only in some cultures, for example, Taiwan. In others, like Tunisia, girls showed more variability. This suggests that culture, not biology, drives women out of math fields.



International Data

It has been suggested that cultural influences on math skills may be nullified by single-sex education. Single-sex schooling systems are seen in some Muslim countries, so to see if this theory was true the researchers took a close look at the data from Middle Eastern countries (Carrell, 2009).
