Esselman, Brian J.; Block, Stephen B. – Journal of Chemical Education, 2019
The VSEPR model has well-established limitations in its ability to represent accurate molecular and electronic geometries of simple molecules, which can create a significant need for students to relearn structure and bonding concepts in organic chemistry. We present an alternate method for describing molecular geometries and electronic structures…

Fung, Fun Man; Choo, Wen Yi; Ardisara, Alvita; Zimmermann, Christoph Dominik; Watts, Simon; Koscielniak, Thierry; Blanc, Etienne; Coumoul, Xavier; Dumke, Rainer – Journal of Chemical Education, 2019
Field trips are a common activity for instructors to engage students and give them a first-hand understanding of a subject, especially in environmental chemistry. However, the planning and execution for a field trip is logistically challenging and demanding of human and material resources. Here, we demonstrate the conduct of a virtual overseas…

Suroviec, Alice H.; Jones, Katarina; Sarabia, Grace – Journal of Chemical Education, 2019
Flavonoids have been studied extensively for their antioxidant properties. Specifically, the flavonoids in tea, such as catechin and epigallocatechin gallate, have been shown to have positive health effects. These compounds are also oxidizable, so the concentrations of these compounds in a given kind of tea can be determined using cyclic…

Pratt, Justin M.; Yezierski, Ellen J. – Journal of Chemical Education, 2019
Chemistry-specific informal science education (chemistry outreach) is widely practiced across all levels of the chemistry community. College students associated with American Chemical Society and Alpha Chi Sigma collegiate chapters are one population of chemistry outreach practitioners who reach upward of 1 million people every year. Previous…

Franco, Jimmy; Provencher, Brian A. – Journal of Chemical Education, 2019
In recent years, researchers have worked diligently to identify more effective means of facilitating student learning. Some promising pedagogical techniques that have emerged include the flipped-class model and test-enhanced learning. These pedagogical strategies have been incorporated into a multitouch book. A multitouch book is a dynamic…

Kent, James E.; Bell, Nicholle G. A. – Journal of Chemical Education, 2019
NMR is a fundamental part of any undergraduate chemistry degree, and training students how to measure and interpret NMR spectra is essential for postgraduate research or chemistry-based careers. Traditionally, the undergraduate laboratory experience with NMR is restricted to sample submission for NMR analysis, which is typically conducted by a…

Morales, Christine; Chen, Franklin – Journal of Chemical Education, 2019
The effects of substitution on reaction rates are at the heart of both physical chemistry and organic chemistry. In this paper, we present a computational laboratory module to explore the effects of group substitution and isotopic substitution on reaction rates by using a readily accessible graphical interface, a computational engine, and…

Kolonko, Erin M.; Kolonko, Kristopher J. – Journal of Chemical Education, 2019
Strategies for teaching NMR spectral interpretation in the undergraduate organic chemistry curriculum are often faculty-centered and can lead to student reliance on rote memorization and "guess and check" methods rather than critical-thinking skills for structure determination. This article describes a student-focused methodology for the…

Scott, Dane; Firth, Daniel – Journal of Chemical Education, 2019
Statistical process control (SPC) is used in the chemical industry to monitor manufacturing and laboratory processes to ensure quality and compliance with regulatory requirements. Control charts are a key tool used in this monitoring. Industrial job postings desire experience with SPC. Most undergraduates entering the workforce have no exposure,…

Hofmann, Andreas; Coster, Mark J.; Taylor, Paul – Journal of Chemical Education, 2019
The interactive generation of chemical-structure diagrams is an integral activity in the study of chemistry as well as in professional chemistry environments. For educational purposes in particular, the existence of suitable software tools free of charge is of great importance. Although a number of free chemical-drawing applications are currently…

Enneking, Kory M.; Breitenstein, Graham R.; Coleman, Amelia F.; Reeves, James H.; Wang, Yishi; Grove, Nathaniel P. – Journal of Chemical Education, 2019
The laboratory has occupied an important place in the general chemistry curriculum for well over a century, despite the fact that many have voiced concern about its value and utility. In an effort to potentially increase capacity in our general chemistry courses, we developed and implemented a hybrid laboratory curriculum that consisted of…
