This $299,033 National Science Foundation project grant supports research and development to improve undergraduate chemistry education. Funded under the NSF's STEM Education program (CFDA 47.076), the collaborative project between the University of North Carolina at Greensboro and University of Wisconsin-Madison aims to study connections between instructional practices and student learning outcomes related to molecular symmetry in inorganic chemistry courses. Over three years, the researchers will conduct case studies of 26 inorganic chemistry courses, collecting quantitative and qualitative data through instructor and student interviews, classroom observations, course materials, and assessments. The analysis seeks to characterize teaching practices and environments, understand how they impact student learning of symmetry, and identify topic-specific professional development needs. Findings will advance knowledge of symmetry instruction and learning, with potential to enhance undergraduate chemistry education nationally.
