From NCWIT (National Council of Women in IT) –
Did you know that a recent study using data on 15,000 students from the National Center of Education Statistics found that teachers consistently rate girls as less good at math than boys, even with similar grades and test scores? Researchers in the study found that while on average teachers rate minority students lower than their white male counterparts, these differences disappear once grades are taken into account. However, they found patterns of bias against white girls that can’t be explained by their academic performance. According to one of the study’s authors, the misconception that white girls can’t handle math persists “Because the idea that men and women are different in this regard is considered natural, and not discriminatory.” At the same time, teachers may be more aware of race and ethnicity – and the problems of racial discrimination – than they are when it comes to gender.
