NMR spectroscopy is traditionally taught to students during Organic Chemistry as a tool used for the determination of structures after synthesis. However, modern NMR spectroscopy has many important applications beyond structure elucidation, including molecular profiling of complex mixtures as biofluids and food samples. In this experiment,…

Context-Based Learning (CBL) and learning through developing and using models are two important teaching approaches for chemistry conceptual understanding. We aimed to examine the influence of a CBL approach on students' understanding of Multiple Models of Knowledge Representations ("MMKRs") and "multiple molecular…

A variety of fruits and vegetables, including raspberries, blueberries, Concord grapes, blackberries, strawberries, peaches, eggplant, red cabbage, and red onions, contain flavonoid compounds known as anthocyanins that are responsible for the blue-red color and the astringent taste associated with such foods. In addition, anthocyanins exhibit a…
