In an influential and compelling paper Bronwyn Davies shows the inadequacies of two common theoretical models used to study sex bias in education, sex-role socialization theory and reproduction theory. Along with other feminist thinkers, Davies views the sex gender system as a sociocultural construct, a system of representation that assigns meaning to the individual within a society. The construction of gender duality goes on "in the laws, the family, and private and public schools. It also goes on in the social science models, in the academic and intellectual community, in radical theories, and even, indeed especially, in feminism itself". Davies suggests that the criticism of Carol Gilligan's work moves beyond the gender duality. It is obvious, as Davies insists, that an adequate theory of gender is going to have to allow for radical change if we are not to foreclose on the stages feminist transformations must take.
