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,…

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…

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…

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…

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…

Clark, Ginerva A.; Humphries, Marisha L.; Perez, Jessica; Udoetuk, Stella; Bhatt, Kruti; Domingo, Jennifer P.; Garcia, Megan; Daubenmire, Patrick L.; Mansuri, Nazminbano; King, Maripat – Journal of Chemical Education, 2020
Knowledge of functional groups provides students with a language for organic chemistry. However, students in a health science chemistry course do not plan to be synthetic organic chemists and, therefore, need examples of how functional group chemistry is relevant to their vocational goals. We have developed a lab to demonstrate how simple…

A green chemistry experiment is presented for teaching an undergraduate quantitative analysis/analytical chemistry laboratory class through the use of black tea leaf extract for the determination of iron in supplement tablets. Dried tea leaf is a safe, low cost, and widely available source of natural extract that can be used in place of more toxic…

Dauzvardis, Fabian; Knapp, Alexander; Shein, Kaung Nan Dar; Lisensky, George – Journal of Chemical Education, 2020
In this brief experiment, students create a superhydrophobic surface as an application of polar--nonpolar interactions and redox chemistry. Half of a zincgalvanized steel strip is coated in copper nanoparticles through electroless deposition. A layer of nonpolar octadecanethiol is added to half of that copper surface. Students classify the three…

Dunnagan, Cathi L.; Dannenberg, Devran A.; Cuales, Michael P.; Earnest, Arthur D.; Gurnsey, Richard M.; Gallardo-Williams, Maria T. – Journal of Chemical Education, 2020
Using virtual reality (VR) in educational settings is becoming increasingly popular. The feasibility of replacing an instrumentation-based organic chemistry lab with a VR experience has been evaluated. A VR laboratory experience was designed to teach students how to use an infrared spectrometer and elucidate an unknown structure from the resulting…

Lai, Heyun; Li, Ziqi; Zhu, Shunying; Cai, Longfei; Xu, Chunxiu; Zhou, Qing – Journal of Chemical Education, 2020
This communication describes a method to detect aluminum in gastric drugs by the naked eye using a microfluidic paper-based analytical device ([mu]PAD). Aluminum ions react with chrome azurol S (CAS) and cetyltrimethylammonium bromide (CTAB) to form a colored complex, which generates a colored band on the [mu]PAD. A printed ruler can be used to…
