Recent research on the effects of women's studies courses has indicated that there are two general approaches to teaching: a concern for competence or mastery and a concern for personal change and advocacy. It was hypothesized that students taking a psychology of women course would become more androgynous and masculine in sex-role concept, more assertive, and more positive in their attitudes toward women than students taking other courses. Undergraduate female students, 40 from psychology of women classes and a comparison group of 31 from classes in psychology and political science, completed pre- and post-test questionnaires, specifically, the Bem Sex-Role Inventory, the Rathus Assertiveness Scale, and the Craig Attitudes Toward Women Scale. Data strongly supported the hypothesis and seemed to indicate that some measure of resocialization did take place for the students in psychology of women courses. (Author/HLM)
