ScienceDaily (Jun. 25, 2007) — It figures: Dads have a major impact on the degree of interest their daughters develop in math. That’s one of the findings of a long-term University of Michigan study that has traced the sources of the continuing gender gap in math and science performance.

“We’ve known for a while now that females do as well as males on tests that measure ability in math and science,” said Pamela Davis-Kean, a psychologist at the U-M Institute for Social Research (ISR). “But women are still underrepresented in science, technology, engineering and math graduate programs and in careers based on those disciplines.”

It’s as if women are saying, “I can, but I don’t want to,” according to Davis-Kean.

In a study she presented recently at a campus meeting, Davis-Kean and colleagues analyzed how parents’ values and attitudes affect children’s math performance and later interest, and how these attitudes vary by the child’s gender. They used data from a longitudinal study of more than 800 children and a large group of their parents that began in 1987 and continued through 2000.

They found that parents provided more math-supportive environments for their sons than for their daughters, including buying more math and science toys for the boys. They also spent more time on math and science activities with their sons than with their daughters…

“Fathers’ gender stereotypes are very important in supporting—or in undermining—daughters’ choices to pursue training in math and science,” Davis-Kean said…
