Design and Implementation of an Organic to Analytical CURE Sequence

摘要

This paper describes the design and implementation of a course-based undergraduate research experience (CURE) sequence in chemistry that links a lowerdivision, organic chemistry course to an upper-division, analytical chemistry course. The focus of student research is on blood preservation using trehalose derivatives in order to mimic the tardigrade, a microscopic extremophile, which produces sugar molecules to survive desiccation and freezing. Students created a library of modified sugar molecules in the organic CURE and then evaluated the behavior of those molecules within membranes in the analytical CURE. The CURE sequence has been run with three student cohorts which were selected to match the demographics of all students in the course. This article details the student selection process, the course design, the faculty implementation, and revisions. Fidelity of the CURE is demonstrated with survey results. We also describe adaptation of the research courses to accommodate the COVID-19 restrictions.
