Thought experiments in physics education: A simple and practical example

Thought experiments play a vital role in scientific argumentation. However, implications for pedagogy are generally neglected. In this article, a Galilean thought experiment is used to enhance learning in a college-level physical science course. Both modern and historical perspectives of Galileo's work are presented. As a final project, students explore Galileo's thought experiment in the laboratory using modern detectors with satisfying results. The project experience lends insight into both the content and processes of science. Extensions to other educational contexts are discussed. © 2001 Kluwer Academic Publishers.
