What Physics Instructors Can Learn from Astronomy Teaching

Abstract

A student says, “Even though the physics involved can be basically the same, the setup is what drives me to like astronomy more,” comparing his introductory physics class to his introductory astronomy class. Another student concurs, “Astronomy is more exciting.” What is it about astronomy that appeals to students? Is there a way to harness such enthusiasm within the context of an introductory physics class while retaining the same level of rigor? Here, we describe a study that shows that, compared with an introductory physics course for science and engineering majors, an introductory astronomy course (also for science and engineering majors) had similar gains on the Force Concept Inventory (FCI), but students’ attitudes and approaches to problem solving were significantly better in the latter. Moreover, interviewed students corroborated the survey findings that the astronomy course was significantly more enjoyable and engaging. This suggests that physics instructors can learn from the way astronomy is often taught, in order to better engage students.
