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…

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…

Fatemah, Amal; Rasool, Shahzad; Habib, Uzma – Journal of Chemical Education, 2020
Students undertaking courses in the field of chemistry need to integrate their spatial skills and conceptual knowledge. However, model perception along with the understanding of spatial processes and spatial structures of molecules has been a cause of difficulty for students as conventional teaching methods cannot fully aid student comprehension.…

Lipton, Mark A. – Journal of Chemical Education, 2020
The material of a standard second-year undergraduate organic chemistry class has been reorganized and reframed to emphasize the mechanistic connections between reactions and to clarify the language with which organic reaction mechanisms are discussed. Assessment of the results of this reorganization shows that student test scores do not decline in…

Xie, Mingrou; Inguva, Pavan; Chen, Wenqian; Prasetya, Nicholaus; Macey, Andrew; DiMaggio, Peter; Shah, Umang; Brechtelsbauer, Clemens – Journal of Chemical Education, 2020
The objective of the presented module is to train students with no background in process development and scaleup of chromatographic processes to a high level of competency within 40 contact hours. The key pedagogical approach is "progression" where students' capabilities are gradually built up with appropriate scaffolding provided at…

Panda, Debashis; Patra, Soumyadip; Awasthi, Mahendra Kumar; Singh, Sanjay Kumar – Journal of Chemical Education, 2020
To understand critical problems associated with solid waste and its consequences for the environment, a laboratory experiment is presented on the synthesis of aluminum-based metal-organic framework (MOF) MIL-53(Al) from household waste (PET bottles and aluminum foil/can), for undergraduate students of chemistry. This work is designed to teach…

Green, Michael; Chen, Xiaobo – Journal of Chemical Education, 2020
For undergraduate students to be prepared for graduate school and industry, it is imperative that they understand how to merge the theoretical insights gleaned through their undergraduate education with the raw data sets acquired through materials analysis. Thus, the ability to implement data analysis is a vital skill that students should develop.…
