This study explores what students understand about enzyme–substrate interactions, using multiple representations of the phenomenon. In this paper we describe our use of the 3 Phase-Single Interview Technique with multiple representations to generate cognitive dissonance within students in order to uncover misconceptions of enzyme–substrate interactions.
The goal of this project was to create an inquiry activity to teach symmetry elements and symmetry operations in an inorganic chemistry course. Many students experience difficulty when building and mentally manipulating three-dimensional mental models from two-dimensional images, causing difficulty when learning symmetry. Process-oriented, guided-inquiry learning (POGIL) was used to structure the activity using a learning cycle paradigm consistent with research on how students learn as described by Novak’s human constructivism theory.
Thermotropic liquid crystal phases are ordered fluids found, for some molecules, at intermediate temperatures between the crystal and liquid states. Although technologically important, these materials typically receive little attention in the undergraduate curriculum. Here, we describe a laboratory activity for introductory organic chemistry students on the synthesis and characterization of the p-alkoxybenzoic acids.
The high-performance liquid chromatography (HPLC) experiment, most often done in the undergraduate analytical instrumentation laboratory course, generally illustrates reversed-phase chromatography using a commercial C18 silica column.

The Chemistry Education Research Doctoral Scholars Program aims to recruit, train and graduate a diverse group of scholars in chemistry education research (CER) who specialize in assessment; design coursework, K-12 partnerships, research experiences, and mentoring to successfully prepare these scholars for careers in CER; and create a community of scholars to collaborate and systematically improve assessment of student learning.
