Abstract
The authors investigated two questions. First, who successfully crossed gender boundaries to study in non-traditional major in relation to his or her gender? Second, what factors affected these boundary-crossing students in making decisions of college or university majors? Based on the analyses of Taiwan Integrated Postsecondary Education Database for a representative sample from the 2005 freshmen class, this study found that less than 10% chose majors non-traditional to their genders. Logistic regression analyses revealed that institutional factors exerted strong constraining effects, and that females/males and vocational/academic track students showed different concerns and decision making patterns while choosing non-traditional departments. In general, research hypotheses were found confirmed only for males, but not for females. Theoretical and policy implications and suggestions for further research are discussed.
