Abstract

Introductory Biology 152 at the UW Madison recently began an entirely case-based approach to teaching plant physiology, ecology, and evolution. Undergraduates work through a series of six cases, each comprised of a specific biological scenario addressing one or more of the three course topics. Students address these cases by conducting in depth research using primary literature and online resources. Ultimately, each student submits a written solution, assessed by their Teaching Assistant (TA). TAs undergo substantive grading calibration at the conclusion of each case. Preliminary analysis suggests that this approach is highly successful at improving students’ science writing and critical reasoning skills. Student responses have been largely positive, and, when critical, useful in the further development of our model. This paper provides an overview of this innovative approach to biology education.
