ancarett writes "Researchers from the University of Texas at Austin found that American high school math teachers tend to rate white female students’ math abilities lower than those of their white male peers, even when their grades and test scores are comparable. Their research drew from the Education Longitudional Study (2002) with data on about 15,000 students and their teachers. According to the researchers "teachers hold the belief that math is just easier for white males than it is for white females." Their findings appear in the April 2012 issue of Gender & Society."
