Smith, Catherine J.; Mansfield, Steven J.; Anderson, Edward A.; Burton, Jonathan W. – Journal of Chemical Education, 2019
Organic synthesis in a modern research laboratory uses state-of-the-art equipment to provide inert atmospheres, track reaction progress, and facilitate the purification of intermediates. Such facilities are not available in a high school laboratory. In this paper, synthetic organic chemistry is taken back to basics: A four step total synthesis of…

Blackburn, Richard A. R.; Villa-Marcos, Barbara; Williams, Dylan P. – Journal of Chemical Education, 2019
A series of laboratory themed simulations developed by Learning Science Ltd. were integrated into a first year laboratory module at the University of Leicester. These simulations allow students to attempt the experiments they will do in the laboratory in a risk-free way that provides the opportunity to make mistakes and learn how to correct them…

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…

Lindsay, Andrew J. – Journal of Chemical Education, 2019
A semester-long, project-based series of laboratory exercises is described that provides practical experience of the upstream and downstream processes involved in monoclonal antibody production. This 6 week project is aimed at final year undergraduate students undertaking primary degrees in biotechnology, biochemistry, or related disciplines.…

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…

"Escape ClassRoom "CSI 1.0"" is an educational escape room proposed as an interactive analytical chemistry exercise for the evaluation of undergraduate students at the end of the subject. This approach is a new form of live action learning activity in which the students have to solve an analytical problem, namely, "an…

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…

Schneider, Elia M.; Bärtsch, Amadeus; Stark, Wendelin J.; Grass, Robert N. – Journal of Chemical Education, 2019
A simple synthesis of fluorescent carbon quantum dots from lemon juice is described to introduce advanced high-school students and undergraduate college students to nanoparticle synthesis and quantum dots. The synthesis is based on the carbonization of lemon juice using only a hot plate stirrer. Column chromatography is used to separate different…

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…

Lazenby, Katherine; Rupp, Charlie A.; Brandriet, Alexandra; Mauger-Sonnek, Kathryn; Becker, Nicole M. – Journal of Chemical Education, 2019
Understanding the nature and purpose of models, including mathematical models, is critical to enabling undergraduate chemistry students to use models to predict and explain phenomena. However, students often do not have systematic conceptions about different kinds of models. To gain a sense of how students understand different models in the…

Ferraro, Giovanni; Fratini, Emiliano – Journal of Chemical Education, 2019
A procedure for one-pot preparation and characterization of silver 1D nanostructures is described. The main advantages of this synthetic approach are the simplicity and reproducibility, where the size of the final product can be controlled just by changing the reaction time. This experiment is designed as a laboratory introduction to colloidal…

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…

Bokosmaty, Rena; Bridgeman, Adam; Muir, Meloni – Journal of Chemical Education, 2019
As part of curriculum renewal in three introductory chemistry courses at the University of Sydney, a partially flipped classroom model was implemented. Content that is conventionally delivered in the in-class sessions was moved online through the use of web-based tutorials, videos and quizzes. During the in-class sessions, active learning…
