My research group focuses on improving conceptual understanding of chemistry with a focus on the dynamics of teaching chemistry and teacher change. The goal of our work is to markedly reform instruction and improve learning across a variety of grade levels (high school and college). Projects employ quasi-experimental designs as well as phenomenological methods which explore particulate-centered curricula, teacher beliefs and change, questioning strategies, chemistry self-concept, evaluating external representation use in inquiry instruction, alignment between stated and enacted curricula, and characterizing teaching and learning in chemistry outreach. My group is enthusiastic about collaborating with faculty, graduate students, and undergraduate students from complementary disciplines.
