A related purpose of the present study was to evaluate the revised questionnaire with science majors and nonscience majors. Most studies of the motivation to learn science, including earlier studies with the questionnaire, focused on nonscience majors because instructors often find it challenging to motivate them (Druger, 2006). But the motivation of science majors also merits attention. Too many science majors are not making it through the academic ‘‘pipeline’’ leading to careers in science, and some groups of science majors are underrepresented in the pipeline, such as women in the physical sciences (National Science Foundation, 2002; Xie & Shauman, 2003). It is, therefore, important to assess the motivation of science majors and nonscience majors
