Talk Title: Supporting the Teaching of Spectroscopy Concepts Using Models


Effectively mastering organic chemistry means having the ability to recognize structural patterns, identify properties or behaviors as a result of patterns, manipulate and transform representations, and predict future outcomes. Often students rely on rote memorization of seemingly disconnected information instead of developing a sound understanding and finding meaning in scientific representations. Spectroscopic techniques, such as infrared and proton nuclear magnetic resonance spectroscopy, are essential analytic tools addressed in organic chemistry instruction. These tools have the potential to reinforce fundamental molecular phenomena and facilitate an understanding of structure-property relations. In this talk, I will discuss a physical model designed to help students visualize concepts involved when solving infrared spectra and augmented reality models developed to support visualization of the concepts relevant to proton nuclear magnetic resonance spectroscopy. Both models have a corresponding worksheet to facilitate their use. The resources guide students in understanding the underlying principles of these spectroscopic methods to deter the need for memorization. The development, implementation, and evaluation of both resources will be presented.
