Researchers with the University of Texas at Austin have determined that female students who associate with high-achieving same-sex peers are more likely to perform better in subjects such as math, science, and English than do girls who don't surround themselves with fellow superior students.
An article on the UT-Austin website reported on the research in 2005 that led to this conclusion:
Using transcripts of 2,500 male and female high school students, their research tracked participants' grades and courses in math, science and English and examined how their friendship groups affected their academic outcomes. The research was funded by grants from the National Institute of Child Health and Human Development and the National Science Foundation and included 13,000 students nationwide.The peer-performance connection does not appear to exist for boys, a fact that at least one of the researchers attributed to the differing value that boys and girls appear to place on the concept of academic collaboration.
"Having friends that are high performers is associated with advanced course-taking in all three subjects," [Dr. Catherine] Riegle-Crumb said. "Yet, what is unique to math and science is the positive association that comes from a friendship group that is predominantly female. Thus, the estimated effects of friends do vary based on the gender composition of the group, but only in math and science, areas where women have been historically under-represented.
"This suggests that the dominant presence of friends who are doing well is a visible reminder that females can do well in subjects stereotyped as male."
"The girls seem to know they can work together and support one another," Riegle-Crumb said in the article on the UT-Austin site. "They can compete and push each other to succeed in the classroom and there can be multiple winners, where the boys tend to take a winner-takes-all approach. They see a zero-sum game where there can be only one winner."
