In general, women earn substantial proportions of the bachelor’s degrees in math and sciences, except in computer sciences, physics and engineering. (2004)

One purpose of this program is to overcome two stereotypes: that women can’t do science, or if they do, they must be nerds.
Science connections, undergraduate

Culturally based values and understandings that affect men and women from infancy on perpetuate certain beliefs; that men are smarter, more committed and harder workers, and “belong” more in the workplace, and that mathematical talent – the basis for all science and technical fields – is more innate than learned and is gendered (a belief common in the United States, but not everywhere). Cultural values shape and can inhibit girls and women’s beliefs in their own ability and their behaviors when confronted with discriminatory practices and with sexual harassment. Even when women themselves do not recognize discrimination’s presence, it marginalizes and demoralizes them.
