Why Every College Student Needs To Take Science Courses

My “day job” is as a physics professor, and one of the things those of us in the business agonize about is the steep drop-off in students taking physics at various levels. Using statistics from the AIP, nearly 40% of high-school students take physics, while putting together enrollment numbers and the total college population suggests that the fraction of college students taking physics is a factor of ten smaller (this is a crude estimate, and seems low but not wildly implausible). Very few of those take anything beyond an introductory course required for some other major– years ago, I went to a conference on introductory physics teaching, and the factoid I remember is that only around 3% of students who take the intro course go on to take another class.

The problem is particularly acute for physics, because we have a (not undeserved) reputation as the hardest and most mathematical of the sciences, but it’s part of a more general phenomenon. Lots of students take science in high school because it’s required (either formally as a graduation requirement, or informally as a “you need to take this set of elective courses if you want to get into a good college” kind of thing), then run away as fast as they can when they get to college, and have (nearly) full control of their course selections.
