Resumen
Science education research has shown that solving case studies helps students to develop higher-order analytical skills while discovering the usefulness of conceptual knowledge in solving real-world problems. In order to support team-based learning and promote student curiosity, two case studies highlighting relevant topics in the media were developed for use in a flipped undergraduate general chemistry sequence. The first is a case involving the determination of the molecular formula of a pharmaceutical. Students work in teams and use their knowledge of stoichiometry to determine the identity of the compound. The second, an interrupted case spanning two courses, is pulled from media reports about arsenic in apple juice. Student teams use their knowledge of periodic properties, electron configurations, and molecular geometry to investigate elemental arsenic and As-containing compounds and also research arsenic’s toxicological effects. Both cases are described in this paper along with details regarding how they are implemented and assessed. Student opinions on the use of case studies are also presented.
