Vitaku, Edon; Christie, Hamish S. – Journal of Chemical Education, 2019
A reliable method for bleach-based alcohol oxidation has been developed. Use of sodium bisulfate as the acid additive in the reaction mixture eliminates the various problems associated with acetic acid, which has commonly been used for this type of oxidation. By conducting the reaction in an ethyl acetate/water two-phase reaction mixture,…

Pergantis, Spiros A.; Saridakis, Lakovos; Lyratzakis, Alexandros; Mavroudakis, Leonidas; Montagnon, Tamsyn – Journal of Chemical Education, 2019
Teaching the concept of pH buffers is considered to be important both in the final high-school years and at the early undergraduate level. Here, we propose the use of pH-log C diagrams to investigate the properties of pH buffers. This graphical approach is extremely simple to employ because it only requires drawing a simple square that can then be…

Kovarik, Michelle L.; Robinson, Jill K. – Journal of Chemical Education, 2019
A collaborative learning module for teaching protein mass spectrometry has been developed to overcome common obstacles to incorporating the modern topic of biological mass spectrometry into the undergraduate chemistry curriculum. Protein mass spectrometry data is provided to eliminate the need for expensive instrumentation, and an instructor's…

Wright, Lyniesha C.; Oliver-Hoyo, Maria T. – Journal of Chemical Education, 2019
A physical model has been designed to help students visualize concepts involved when solving infrared spectra. The physical model uses balls and springs to incorporate the harmonic oscillator model and Hooke's law to study dynamic vibrations within diatomic molecules. Various concepts are addressed with the model to abstract principles about how…

In this mixed-methods study, undergraduate students identified with a learning disability indicated their preferred instructional approaches to learning in college-level STEM courses. The relationships between preferred instructional strategies and learner characteristics: (a) declared major; (b) learning disability; and (c) gender were examined.…

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…

Yates, Nicholas D. J.; Brabham, Robin L.; Spears, Richard J.; Keenan, Tessa; Helliwell, Philip A.; Pugh, David S.; Parkin, Alison; Hurst, Glenn A.; Fascione, Martin A. – Journal of Chemical Education, 2019
A laboratory experiment introducing the concept of chemical bioconjugation of proteins to undergraduate students in a therapeutically relevant context was developed. Initially, students installed an aldehyde functionality into a protein via the oxidation of the N-terminal threonine residue of the cholera toxin subunit B (CTB) protein, which was…

Stover, Shawn K. – Bioscene: Journal of College Biology Teaching, 2019
This article describes an activity designed to hone students' lay communication skills. After carefully analyzing journal articles that highlight specific aspects of vertebrate physiology, students generate "press releases" to summarize experimental results and suggest potential applications of the research. By producing succinct,…

Bridoux, Stephanie, Ed.; Grenier-Boley, Nicolas, Ed.; Caroline Leininger-Frezal, Ed. – John Wiley & Sons, Inc, 2023
This book offers an overview of the research carried out in didactics on the teaching and learning of science at university from the perspective of university pedagogy. The first part sheds light on the links between university pedagogy and didactics, by studying the nature and place of disciplinary pedagogical knowledge at university and the…

Mastery of quantitative skills is increasingly critical for student success in life sciences, but few curricula adequately incorporate quantitative skills. Quantitative Biology at Community Colleges (QB@CC) is designed to address this need by building a grassroots consortium of community college faculty to (1) engage in interdisciplinary…

Boyd M. Goodson; Qingfeng Ge; Lichang Wang – Journal of Chemical Education, 2023
Over the past 20 years, significant effort has been devoted to advancing the modular approach to teaching chemistry laboratory courses. The development and implementation of two modules are presented here for teaching a second-semester physical chemistry laboratory course using the modular approach: an inquiry-based module concerning proteins and…

Khong, Mei Li; Tanner, Julian A. – Biochemistry and Molecular Biology Education, 2021
Examinations present an intensely focused opportunity for student learning yet opportunities for collaboration, communication, and feedbacks are often wasted. Two-stage examinations where students first take examinations individually and then repeat the examination in small groups hold promise to address this issue. Here, we pilot and evaluate a…

Terrell, Cassidy R.; Nickodem, Kyle; Bates, Alison; Kersten, Cassandra; Mernitz, Heather – Biochemistry and Molecular Biology Education, 2021
Introductory biochemistry courses are often challenging for students because they require the integration of chemistry, biology, physics, math, and physiology knowledge and frameworks to understand and apply a large body of knowledge. This can be complicated by students' persistent misconceptions of fundamental concepts and lack of fluency with…
