The Bray Speth group includes graduate and undergraduate biology students who conduct research on college-level biology teaching and learning.
We investigate how active-learning pedagogical strategies promote understanding of complex biological systems and processes in large-enrollment introductory biology courses.
Ongoing projects focus on:
1. assessment of systems thinking skills through student-generated models and explanations of complex biological processes;
2. student understanding and representation of the gene-to-phenotype relationship and of the origin of genetic variation;
3. infusing evolutionary reasoning into introductory molecular, cellular and organismal biology.
Students are welcome to contact me for a more detailed description of ongoing projects.
