Research Description

The focal point of our work is the study, reflection, and improvement of chemistry education. In particular, we have directed our research at trying to characterize the conceptual frameworks and the patterns of reasoning used by chemistry students to answer questions and solve problems that require qualitative reasoning (e.g., classification, prediction, inference, comparison). We are also exploring how students' ideas and reasoning strategies evolve as they develop more expertise in the discipline (trajectories of expertise). These studies are of central importance to design learning progressions that foster meaningful learning. Read More.
