Bancroft, Senetta F.; Fowler, Samantha R.; Jalaeian, Mohammadreza; Patterson, Katie – Journal of Chemical Education, 2020
Traditionally underserved students (TUSs), including Black, Latinx, American Native, and low-socioeconomic (SES) students, have higher rates of departure from STEM undergraduate programs than their more privileged peers. These higher departure rates are associated with TUSs' lower performance in STEM gatekeeper courses compared to non-STEM courses…

Goh, Hui Yi; Wong, Wei Wen Clarence; Ong, Yue Ying – Journal of Chemical Education, 2020
Chemical waste should be reduced to minimize environmental pollution, and it is important that the amount of waste is minimized in chemistry teaching laboratories to reduce the negative impact on environment as well as the disposal costs of university. There are several ways to minimize the waste generated in chemistry teaching laboratories,…

Pinger, Cody W.; Geiger, Morgan K.; Spence, Dana M. – Journal of Chemical Education, 2020
Wide accessibility and a broad range of applications have made 3D-printers a commonplace tool in the science community. From tier-one research institutions to community public libraries and high schools, 3D-printers are being used to enrich STEM education through a variety of learning techniques and experiences. Reports of 3D-printed models for…

Vangunten, Matthew T.; Walker, Uriah J.; Do, Han G.; Knust, Kyle N. – Journal of Chemical Education, 2020
We demonstrate that the simplicity of preparing functional microfluidic devices using 3D printing is well suited for undergraduate laboratories. Educational experiments utilizing non-paper-based microfluidic devices are often relegated to well-equipped, resource rich universities because traditional fabrication techniques require specialized and…

Casselman, Matthew D.; Atit, Kinnari; Henbest, Grace; Guregyan, Cybill; Mortezaei, Kiana; Eichler, Jack F. – Journal of Chemical Education, 2020
The use of the flipped classroom approach in higher education STEM courses has rapidly increased over the past decade, and it appears this type of learning environment will play an important role in improving student success and retention in undergraduate chemistry "gatekeeper" courses. Many adopters of the flipped classroom structure…

Nehring, Andreas; Busch, Sebastian – Journal of Chemical Education, 2020
Although demonstrations play a central role in teaching and learning chemistry, the effects of concrete setup principles have rarely been subject to systematic empirical studies. According to the left-to-right principle, the educator should begin with the first step of a reaction in the upper left part of the setup and then place the following…

Wu, Nancy; Kubo, Tomohiro; Hall, Ariana O.; Zurcher, Danielle M.; Phadke, Sameer; Wallace, Rachel L.; McNeil, Anne J. – Journal of Chemical Education, 2020
Although teaching laboratories offer students the opportunity to act and think like chemists, in many cases students simply follow written procedures to generate predetermined outcomes. In recent years, there has been a movement toward inquiry-, problem-, and discovery-based learning. In a similar vein, the first-semester introductory organic…

Demoranville, Leonard T.; Kane, Olivia R.; Young, Karin J. – Journal of Chemical Education, 2020
Connecting chemical concepts with real-world applications has been demonstrated to increase persistence, student attitudes, and performance. In a one-semester general chemistry course, most laboratory exercises were designed to have direct implications on real-world issues, and students were asked to consider these implications. Students blogged…

Subratti, Afraz; Lalgee, Lorale J.; Jalsa, Nigel K. – Journal of Chemical Education, 2020
A magnetic stirrer is an indispensable instrument in any laboratory setting. Commercially available stirrers are costly and have a defined life-span. The construction of a low-cost magnetic stirrer based on pulse width modulation is described. The design reported uses mainly recycled parts which results in a robust and efficient device at a very…

An, Jiwoo; Poly, Laila-Parvin; Holme, Thomas A. – Journal of Chemical Education, 2020
In general chemistry laboratories, students learn practical laboratory skills through hands-on activities and are exposed to new scientific instruments. However, these instruments are often viewed as black boxes for various reasons, where students do not know how to use them or what the instruments are capable of. This tendency is likely to induce…

Kennedy, Jacob S.; Larson, Garrett E.; Blumenfeld, Alex; Waynant, Kristopher V. – Journal of Chemical Education, 2020
Carbohydrates are an essential group of molecules to the organic chemistry classroom providing molecular relevance to a common ingredient in chemical biology. While the meticulous elucidation of the carbohydrate structures by Fischer and others is an engaging topic in the lecture, there are few laboratory experiments that can emulate carbohydrate…

Armesto, Antia Gómez; Muñoz, Juan Carlos Nóvoa; Estévez, Manuel Arias; Delgado, Avelino Núñez; Rodríguez, Esperanza Álvarez; Sanjurjo, Maria José Fernández – Journal of Chemical Education, 2020
A laboratory experiment to study the effect of soil amendments in the bioremediation of polluted soils is described. Students extracted and measured 0.01 M CaCl[subscript 2]-soluble Cd, EDTA-soluble Cd, and DTPA-soluble Cd concentrations in contaminated soils, treated with a liming material (mussel shell), and/or with an organic amendment (pine…

Kodani, Satoki; Fukuda, Masahiro; Tsuboi, Yoji; Koga, Nobuyoshi – Journal of Chemical Education, 2020
This study focuses on designing a laboratory learning program for a high school chemistry course in which students could discover the fundamental principles of Hess's law via stepwise inquiry. By exploring the chemical properties of common desiccants, mainly those that were reactive in water, students were introduced to the exothermic reaction of…

Frazer, Laszlo; Higginbotham, Heather F.; Bell, Toby D. M.; Funston, Alison M. – Journal of Chemical Education, 2020
Analysis of stochastic processes can be used to engender critical thinking. Quantum dots have a reversible, stochastic transition between luminescent and nonluminescent states. The luminescence intermittency is known as blinking and is not evident from ensemble measurements. In order to stimulate critical thinking, students design, perform, and…

Sanii, Babak – Journal of Chemical Education, 2020
Augmented reality (AR) is a means of superimposing artificial 3D objects over the real world via a mobile device. An AR standard file format has been recently implemented on mobile devices that current students commonly own. Here we describe three relatively nontechnical methods to produce 3D AR objects for chemistry courses and demonstrate their…
