Alexander Grushow – Journal of Chemical Education, 2022
A revised version of a traditional physical chemistry laboratory experiment has been developed to enhance student discussion in the laboratory and to improve students' connections between physical chemistry concepts and real molecular systems. In this experiment, students explore the keto-enol tautomerization of 2,4-pentanedione. However, unlike…

Shannon J. Saluga; Hannah Peacock; Daniel D. Seith; Casadora C. A. Boone; Yasamin Fazeli; Rebecca Mai Huynh; Jinyu Luo; Zane Naghi; Renée D. Link – Journal of Chemical Education, 2022
Remote delivery approaches to laboratory courses in the response to the COVID-19 pandemic have included a spectrum spanning passive options such as providing students with prerecorded videos of experiments to replacing in-person laboratory experiences with immersive virtual reality environments. While interactive activities that require students…

Sheppard, Caroline – Journal of Chemical Education, 2021
Laboratory safety is a vital part of a chemical education and can be incorporated into courses throughout the chemistry curriculum. Discussions of laboratory safety can serve as an introduction to the important field of green chemistry. Exposure to this field can better prepare students for safer and more sustainable laboratory practices in…

Faulconer, Emily K.; Faulconer, Laura S.; Hanamean, James R. – Journal of College Science Teaching, 2019
At first glance, scientific laboratory experiences might appear to be challenging to move to the cloud. Skeptics may point to sensory feedback limitations and inequivalence of student outcomes. However, emerging data increasingly provide evidence that scientific laboratory courses are not only amenable to online learning, but also can deliver…

Fracaroli, Alejandro M.; Caminos, Daniel A. – Journal of Chemical Education, 2021
Scientists understand that no result is more important than the welfare of the investigators and the people around them. Safety culture is an integral part of industrial and academic jobs; however, safety training has only recently been added to chemistry classroom and laboratories. Chemistry laboratories expose workers to a variety of hazards,…

Shani Jonson – Learning Assistance Review, 2024
In the article "Understanding Writer Center Use among Community College Students," Christina Savarese addresses the reasons students use the writing center, understanding those reasons, and using them to identify ways the writing center administrators and tutors can better serve their student population. Additional research findings…

Arthur, Peter G.; Zareie, Reza; Kirkwood, Paul; Ludwig, Martha; Attwood, Paul V. – Biochemistry and Molecular Biology Education, 2018
Assessment is a central component of course curriculums and is used to certify student learning, but it can also be used as a tool to improve teaching and learning. Many laboratory courses are structured such that there is only a grade for a particular laboratory, which limits the insights that can be gained in student learning. We developed a…

Ruiz, Kevin A.; López, Marta; Suppan, Gottfried; Makowski, Kamil – Journal of Chemical Education, 2020
We present an experiment designed to hone the decision-making skills of (undergraduate) chemistry students by using aqueous crossed aldol reactions. Here, we present two simple crossed aldol reactions based on inexpensive and readily available materials: The condensation of vanillin and cinnamaldehyde with acetone. The procedure uses the variation…

Walkup, John R.; Key, Roger A.; Talbot, Patrick R. M. – Physics Education, 2019
A lab activity for teaching physics students the fundamentals of statistical analysis during the first few weeks of instruction is described. This activity involves students timing a pulse of light generated by an Arduino device of fixed duration with individual timers (e.g. stopwatch, iPhone timer). To select the most precise timing methods and…

Cagle, Ethan C.; Totsch, Timothy R.; Erdmann, Mitzy A.; Gray, Gary M. – Journal of Chemical Education, 2018
[superscript 31]P{[superscript 1]H} nuclear magnetic resonance spectroscopy is a particularly useful tool for studying the reactions of P-donor ligands such as phosphines and phosphites with transition metals and other Lewis bases because the reactions take place on the nonbonding pair of electrons on the phosphorus. In addition, [superscript 31]P…

Cole, Renée S.; Muniz, Marc; Harvey, Erica; Sweeney, Robert; Hunnicutt, Sally – Journal of Chemical Education, 2020
In this guided inquiry experiment, students extract catecholase enzyme from apples to catalyze the oxidation of catechol. They follow the reaction using the UV--vis absorbance of the "p"-benzophenone produced to determine the Michaelis-Menten kinetic parameters. Students make selected experimental choices within a structured framework…

Camel, Valerie; Maillard, Marie-Noëlle; Descharles, Nicolas; Le Roux, Even; Cladière, Mathieu; Billault, Isabelle – Journal of Chemical Education, 2021
Educational resources that cover essential knowledge related to chemistry safety rules are openly accessible on the CHIMACTIV website (http://chimactiv.agroparistech.fr/). Organized into two online tracks, the content covers personal and collective protections, first aid, as well as the handling of hazardous chemicals. Being interactive and…

Groos, Lukas; Maass, Kai; Graulich, Nicole – Journal of Chemical Education, 2021
More than ever, there is an increasing need for digital experimental learning environments in chemistry. The variety of digital learning approaches provided to students range from simple videos showing experiments to highly interactive virtual laboratories. Regardless of which approach is chosen, a digital learning environment should be adapted to…

Chateau, Anne; Molle, Nicolas – Language Learning in Higher Education, 2023
The UFR Lansad (Language centre teaching languages to specialists of other disciplines) was created in 2014 at the University of Lorraine. The process leading to its creation was led by a small number of teachers and researchers, from the pre-existing teams of the previous Lorraine universities (Molle et al. 2019). It is the result of didactic…

Vanderveen, Jesse R.; Jessop, Philip G. – Journal of Chemical Education, 2021
Selecting less hazardous chemicals is a core tenet of green chemistry but is difficult to teach in practice. The upper-year undergraduate or graduate level exercise described here empowers students to make such decisions themselves. Students are tasked with finding the greenest chemical for a specific purpose described in a hypothetical scenario,…
