Three years after the president of Harvard, Lawrence H. Summers, got into trouble for questioning women’s “intrinsic aptitude” for science and engineering — and 16 years after the talking Barbie doll proclaimed that “math class is tough” — a study paid for by the National Science Foundation has found that girls perform as well as boys on standardized math tests.

Although boys in high school performed better than girls in math 20 years ago, the researchers found, that is no longer the case. The reason, they said, is simple: Girls used to take fewer advanced math courses than boys, but now they are taking just as many.

“Now that enrollment in advanced math courses is equalized, we don’t see gender differences in test performance,” said Marcia C. Linn of the University of California, Berkeley, a co-author of the study. “But people are surprised by these findings, which suggests to me that the stereotypes are still there.”

The findings, reported in the July 25 issue of Science magazine, are based on math scores from seven million students in 10 states, tested in accordance with the federal No Child Left Behind Act.

The researchers looked at the average of the test scores of all students, the performance of the most gifted children and the ability to solve complex math problems. They found, in every category, that girls did as well as boys. (To their dismay, the researchers found that the tests in the 10 states did not include a single question requiring complex problem-solving, forcing them to use a national assessment test for that portion of their research.)

Janet Hyde, a professor at the University of Wisconsin, Madison, who led the study, said the persistent stereotypes about girls and math had taken a toll.

“The stereotype that boys do better at math is still held widely by teachers and parents,” Dr. Hyde said. “And teachers and parents guide girls, giving them advice about what courses to take, what careers to pursue. I still hear anecdotes about guidance counselors steering girls away from engineering, telling them they won’t be able to do the math.”

Girls are still underrepresented in high school physics classes and, as noted by Dr. Summers, who resigned in 2006, in the highest levels of physics, chemistry and engineering, which require advanced math skills.

The study also analyzed the gender gap on the math section of the SAT. Rather than proving boys’ superior talent for math, the study found, the difference is probably attributable to a skewed pool of test takers. The SAT is taken primarily by seniors bound for college, and since more girls than boys go to college, about 100,000 more girls than boys take the test, including lower-achieving girls who bring down the girls’ average score.

On the ACT, another college entrance test, the study said, the gender gap in math scores disappeared in Colorado and Illinois after the states began requiring all students to take the test.

Here's a quote from the study:

"Greater male variance is indicated by VR > 1.0. All VRs, by state and grade, are >1.0 [range 1.11 to 1.21]."

and the authors acknowledge:

"If a particular specialty required mathematical skills at the 99th percentile, and the gender ratio is 2.0, we would expect 67% men in the occupation and 33% women. Yet today, for example, Ph.D. programs in engineering average only about 15% women."
