Evidence-centered curriculum design and assessment; engaging students in scientific practice; model-based reasoning and argumentation in chemistry contexts

For practicing scientists, models play key roles as communicational resources and tools for reasoning and problem solving. Engaging students in scientific practices, such as using models to predict and explain chemical behavior, has been highlighted as a way to help students develop a deeper understanding of the nature of scientific inquiry and core concepts[1] (National Research Council, 2012). However, there is evidence that traditional instruction alone may do little to help students use models of chemical phenomena effectively. For instance, despite instruction, students may use mathematical models in an algorithmic fashion without deeper understandings of the nature of the model and the conditions for which it would be valid. Students may also struggle to coordinate information across different types of models, for instance from mathematical representations to graphical or atomic-molecular depictions of the system.

Research in the Becker group explores how undergraduate chemistry students develop expertise in using models to predict and explain chemical behavior. Using qualitative and quantitative research methods, we explore the impact of instructional strategies on scaffolding students’ model-based reasoning in chemistry contexts. The goal of this work is to inform the design of evidence-based instructional materials for introductory chemistry courses and to improve student performance and retention in these courses.
