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,…

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…

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…

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…

Irby, Stefan M.; Pelaez, Nancy J.; Anderson, Trevor R. – Journal of Chemical Education, 2020
A course-based undergraduate research experience (CURE) is a teaching approach aimed at developing students' ability to conduct novel research. Although students' perceptions of their learning during CUREs may not reflect actual student learning, such surveys provide a convenient and useful metric for course evaluation. Instructors can use survey…

Lazenby, Katherine; Stricker, Avery; Brandriet, Alexandra; Rupp, Charlie A.; Becker, Nicole M. – Journal of Chemical Education, 2020
To engage meaningfully with scientific models, undergraduate students must come to understand what counts as a scientific model and why. To gain a sense of the characteristics that undergraduate chemistry students ascribe to scientific models, we analyzed survey data that address students' ideas about both model criteria in general and criteria…

Stout, Roland P. – Journal of Chemical Education, 2020
An oral presentation assignment in a Physical Chemistry course was reimagined as a TED talk. The presentation is part of a larger course project which includes consideration of what traits mark good writing and good speaking that students can emulate. Evidence and observations show that this new format yields improved presentations, enhanced…

Wong, Clarence Wei Wen; Goh, Hui Yi; Ong, Yue Ying – Journal of Chemical Education, 2020
The skills and knowledge of the employers of chemists have been explored in varying degrees of specificity. Some studies have argued that the current university curriculum does not prepare students for modern industry adequately, while others have provided an overview of the job market for graduates with a bachelor's degree in chemistry. In order…

Prendergast, Aisling M.; Shanahan, Rachel; Hickey, Aobha; Harrington, Francis; Schönbauer, David; Byrne, Peter A.; Schnürch, Michael; McGlacken, Gerard P. – Journal of Chemical Education, 2020
In the past decade, C-H functionalization has been a very active topic of research in both academia and industry. When a H atom is replaced by an aryl (or heteroaryl) group, the transformation is termed "direct arylation". This approach to the formation of key (hetero)aryl-(hetero)aryl bonds is complementary to traditional methods, such…

Matsubara, Yasuo; Ito, Akitaka – Journal of Chemical Education, 2020
The lifetime of the excited state of a material is essential for characterizing its photophysical and photochemical processes and substantially affects the quantum efficiencies of its luminescence (fluorescence or phosphorescence) and photo(catalytic) reactions. However, undergraduate students are much more likely to do steady-state, rather than…

Hengel, Matt J.; Wong, Jon W.; Redman, Zachary C.; Rering, Caitlin; Williams, Katryn L. – Journal of Chemical Education, 2020
Undergraduate students in an environmental chemistry laboratory course were taught QuEChERS (quick, easy, cheap, effective, rugged, and safe), a sample preparation procedure that is commonly used in pesticide laboratories involving an acetonitrile salt-out extraction of fresh produce samples followed by solid-phase dispersive cleanup using a…
