To determine when girls lose interest in math and science, the authors surveyed female students in grades 4 through 8 in several school districts in southwestern Ohio to try to answer three questions: (1) Do girls stop liking science? If so, at which grade? (2) Do girls stop liking math? If so, at which grade? and (3) Do girls like science and math less than they like language arts and social studies? Although this was not a longitudinal study, it yielded some robust results, which are described in this article.
