My current scholarly interest centers on Biology Education Research. In partnership with researchers at San Francisco State University in the Science Education Partnership and Assessment Laboratory (SEPAL), I investigate how students and faculty in biology conceptualize fundamental principles, organize their disciplinary knowledge, and what changes, if any, emerge over the course of undergraduate biology education. Recently, we developed a novel assessment tool, the Biology Card Sorting Task (BCST). The BCST probes how individuals organize their knowledge of biology. Experimental results suggest that the BCST is robust in distinguishing populations of biology experts and novices and represents a useful tool for policymakers, funding agencies, science departments, and individual biology educators to gauge the development of biological expertise in their undergraduate students and to make informed decisions regarding programmatic and curricular improvements.
