From the site: "Research in the Yezierski Group aims to improve conceptual understanding of chemistry with a focus on the dynamics of teaching chemistry and teacher change. The goal of our work is characterizing and reforming instruction across a variety of grade levels (middle school, high school, and college) and learning environments (formal and informal). Projects employ a variety of designs and methods that explore innovations in particulate-centered curricula, scientific reasoning, chemistry self-concept, learning in chemistry outreach, formative assessment, characterizing animation use and instructional materials, and teacher change."
