Integrative cases for teaching evolution

Abstract

Current university-level evolution instruction often suffers from a disjointed curriculum that separates molecular and ecological processes, at times omitting the former altogether. At the same time, national reform efforts call for the principles of evolution to be taught across the curriculum. We met this challenge by developing four cases (Mouse Fur Color, Pea Taste, Monkey Opsins and Clam Toxin) that present an integrated, comprehensive approach to teaching evolution across biological sub-disciplines. Our intent was to provide materials that post-secondary instructors could use to bolster their content knowledge and adapt for their students as they endeavor to configure their teaching to meet Vision and Change challenges. The material in any given case can be used to support the teaching of evolution across the curriculum, whether within a single introductory or advanced course, or more comprehensively across several courses. The cases are presented in a way that will allow instructors to quickly see how to apply this approach.
