Tree-Thinking in Introductory Biology Evolution Education.

Introductory-level biology majors are often overwhelmed by the amount of data supporting evolution that is typically condensed into only a few lectures "on evolution" during the semester. We are testing whether a curriculum based on Tree-thinking improves understanding and acceptance of evolution. Tree-thinking is an approach to evolution education based on the idea that there is a link between learning evolutionary theory and understanding how evolution is represented in phylogenetic diagrams. This curriculum infuses evolution throughout the semester, presents evolution as a topic for hypothesis testing and experimentation, and gives students experiences they can use to construct their own conceptual understanding of the topic. We present results of the first four semesters of the study, which indicate success with our curriculum, as well as preliminary data from a study of non-majors.
