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…

Singhal, Ishu; Balaji, B. S. – Journal of Chemical Education, 2020
An open-source repository of basic building block models design files for writing chemical formulas, equations, and ionic states are provided. Writing chemical symbols, molecules, and ions in their correct oxidation state or valency in chemical equations is an essential and integral part of learning. For a visually impaired student, it is very…

Kondinski, Aleksandar; Moons, Jens; Zhang, Yujie; Bussé, Jakob; De Borggraeve, Wim; Nies, Erik; Parac-Vogt, Tatjana N. – Journal of Chemical Education, 2020
Single-type, 6-fold symmetrically grooved, and commercially accessible interlocking disks (ILDs) have been used for modeling of sp[superscript 2] hybridized carbon-based nanoarchitectures and complex polyhedral and reticular material models. In the case of the carbon-based nanoarchitectures, we showcase that the primary ILDs can be directly used…

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…

Teichert, Melonie A.; Schroeder, Maria J.; Lin, Shirley; Dillner, Debra K.; Komperda, Regis; Bunce, Diane M. – Journal of Chemical Education, 2020
On the basis of the results of two prior studies at the US Naval Academy (USNA), which described the choice of study resources and the self-reported learning approaches of students of differing achievement levels, the current investigation examines how students of differing achievement levels in general chemistry actually solve multiple-choice…

Leontyev, Alexey; Houseknecht, Justin B.; Maloney, Vincent; Muzyka, Jennifer L.; Rossi, Robert; Welder, Catherine O.; Winfield, Leyte – Journal of Chemical Education, 2020
This account reports building a community of practice for organic chemistry instructors. With support from Chemistry Collaborations, Workshops, and Communities of Scholars (cCWCS), a group of organic chemistry faculty facilitated multiple workshops to introduce active learning techniques to their colleagues across the country. A Web site,…

Scircle, Austin; Cizdziel, James V. – Journal of Chemical Education, 2020
Microplastics (MPs) are small plastic particles (<5 mm in size) that are ubiquitous in the environment and have even been detected in bottled water. In this laboratory experiment, suited for instrumental or environmental chemistry classes, students detect and quantify MPs in bottled water by filtering and staining them with Nile red dye prior…

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…

Wang, Tao; Yin, Weidong; Zhang, Shaoxiong; Li, Zhao; Zhang, Shengjun; Zhang, Bo; Ma, Hengchang – Journal of Chemical Education, 2020
This laboratory experiment visually demonstrates the advanced scientific concept of aggregation-induced emission (AIE) using hands-on learning methods. The experiment is divided into two parts: the first period consists of synthesis and isolation of the organic compound 2(TPA-O)-TPE using typical organic chemistry lab techniques; the second period…

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…

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…

Lam, Chun Ho; Jackson, James E. – Journal of Chemical Education, 2020
Electrocatalytic hydrogenation of acetol (IUPAC: 1-hydroxy-2-propanone), a species formed upon thermal liquefaction of biomass, can be achieved using inexpensive objects: filter paper, coins, batteries, salts, and water. This simple example demonstrates that "green" chemical transformations can be achieved with familiar items and helps…

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…
