Guest: Elaine Seymour.

Between 40 and 60 percent of students entering college planning to major in science, math, or engineering end up switching to other majors before graduation. Sociologist Elaine Seymour surveyed hundreds of students in an effort to find out why so many initally motivated undergraduates abandon science and engineering majors early in their college careers. She joins us on Focus today from the University of Colorado to share her findings.
