Direct linkPollard, Benjamin; Hobbs, Robert; Henderson, Rachel; Caballero, Marcos D.; Lewandowski, H. J. – Physical Review Physics Education Research, 2021
Introductory physics lab courses serve as the starting point for students to learn and experience experimental physics at the undergraduate level. They often focus on measurement uncertainty, an essential topic for practicing physicists and a foundation for more advanced lab learning. As such, measurement uncertainty has been a focus when studying…

Covey, Scott D. – Biochemistry and Molecular Biology Education, 2021
The real time PCR (qPCR) method provides a powerful method to assess levels of particular species of DNA. When combined with reverse transcription (RT-qPCR) it is the predominate technique to measure expression of gene transcripts. While this approach is very powerful, particular care must be taken in the design of the primers to facilitate…

Mastery of quantitative skills is increasingly critical for student success in life sciences, but few curricula adequately incorporate quantitative skills. Quantitative Biology at Community Colleges (QB@CC) is designed to address this need by building a grassroots consortium of community college faculty to (1) engage in interdisciplinary…

DeLeon, Chelsea; Tabibi, Tara; Alagic, Asmira – Journal of Chemical Education, 2020
This work explores the interface between 3D-printing, material sciences, and microfluidics with electrochemical detection in an undergraduate laboratory. This work includes a module for the characterization and electrochemical analysis of microelectrodes that spans 4 weeks (3 h per week). Laboratory exercises include the fabrication of a…

Rogers, Bradley A.; Zhang, Yanjie – Journal of Chemical Education, 2020
The Hofmeister series is a recurring trend that ranks ions' abilities to influence various aqueous processes in solution. Herein, a set of project-based experiments was developed for students in an upper-level physical chemistry laboratory to investigate the specific ion effects on the thermodynamics of caffeine partitioning between aqueous and…

Schmidt, Emily; Vik, Ryan; Brubaker, Benjamin W.; Abdulahad, Sienna S.; Soto-Olson, Diana K.; Monjure, Tia A.; Battle, Cooper H.; Jayawickramarajah, Janarthanan – Journal of Chemical Education, 2020
There is a growing need for workers with STEM-aligned training in the modern global economy, but a paucity of workers to fill these positions. One important contributor to this issue is low student persistence in STEM. Nontraditional science courses that utilize more active-participation and learning are attractive as tools to increase student…

Teaching an Instrumental Analysis Laboratory Course without Instruments during the COVID-19 Pandemic
Dukes, Albert D., III – Journal of Chemical Education, 2020
The COVID-19 pandemic presented numerous challenges for all levels of the education system. In March 2020, virtually all colleges and universities in the United States moved all instruction to an online environment as a result of the pandemic. While this posed challenges for all faculty, it posed a particular challenge for those faculty members…

George-Williams, Stephen; Motion, Alice; Pullen, Reyne; Rutledge, Peter J.; Schmid, Siegbert; Wilkinson, Shane – Journal of Chemical Education, 2020
Educators around the world have been challenged to adapt their teaching and pastoral care rapidly in response to the coronavirus pandemic. In this article, we, the academic members of the Chemistry Education and Communication Research Theme (CECR) from the School of Chemistry at the University of Sydney, reflect on the challenges and successes…

Hermanns, Jolanda; Schmidt, Bernd; Glowinski, Ingrid; Keller, David – Journal of Chemical Education, 2020
In this communication the development of an online course on the topic "organic chemistry" for nonmajor chemistry students is described and discussed. For this online course, the existing classroom course was further developed. New elements such as podcasts, task navigators, and a forum for discussing the solving of tasks or problems…

Bell, Anthony; Christian, Laura; Hecht, David; Huisinga, Kathryn; Rakus, John; Bell, Ellis – Biochemistry and Molecular Biology Education, 2020
Readily available, free, computational approaches, adaptable for topics accessible for first to senior year classes and individual research projects, emphasizing contributions of noncovalent interactions to structure, binding and catalysis were used to teach Course-based Undergraduate Research Experiences that fulfil generally accepted main CURE…

Valdez, Perla; Smith, K. Christopher – Journal of Chemical Education, 2020
A common misconception about dissolving is that heating and/or stirring are required for the dissolving process to occur. In this study, quantitative experimental evidence was collected and analyzed to demonstrate that neither heating nor stirring is required for dissolving. Educators can use the data and results in this study to address this…

Abraham, Liza; Stachow, Laura; Du, Hechao – Journal of Chemical Education, 2020
We report a series of experiments based upon cinnamon oil that were developed to provide a practical integration of green and sustainable chemistry concepts for the organic chemistry laboratory. Five experiments centering around cinnamaldehyde as a green, plant-based chemical were performed by undergraduate students in a second-year organic…

Soong, Ronald; Jenne, Amy; Biswas, Rajshree Ghosh; Adamo, Antonio; Simpson, Andre – Journal of Chemical Education, 2020
The ability to visualize chemical processes can be an asset in a teaching laboratory. Despite the advances in laboratory technology, apparatuses used in the teaching of simple thermodynamics concepts, such as exothermic/endothermic reactions, historically remain unchanged and can benefit from a fresh perspective. The recent incorporation of…

Reid, Scott A. – Journal of Chemical Education, 2020
Many STEM (science, technology, engineering, and mathematics) disciplines require a two-semester sequence of introductory college chemistry, which are thus critical gateway courses to a variety of majors. Recognizing the benefit to educators of a structure of content learning across the chemistry curriculum, in 2012, the American Chemical Society…

With the introduction of the Wireless Smart Cart by PASCO scientific in April 2016, we expect a paradigm shift in undergraduate physics laboratory instruction. We have evaluated the feasibility of using the smart cart by carrying out experiments that are usually performed using traditional PASCO equipment. The simplicity, convenience, and…
