Tomas Linder – Journal of Microbiology & Biology Education, 2024
Anaerobic respiration reactions are of fundamental importance to global biogeochemical cycling of elements. Yet, the idea that cellular respiration can occur not only in the absence of oxygen but also involve the oxidation of inorganic substrates (e.g., AsO[subscript 3 superscript 3-], Fe[superscript 2+], H[subscript 2], H[subscript 2]S,…

Scowcroft, Victoria; Davies, Steve R.; Mathlin, Gary; Sloan, Peter A. – Physics Education, 2023
Astronomy is one of the few sciences where the data (star-light) can be seen by all. Yet, there is a disconnect between a typical undergraduate lecture and, for example, where a planet may be in the sky and how to observe it. With the advent of moderate cost, high-quality 'back-garden' astronomy, and standard computers powerful enough to produce…

Eckert, Rebecca A.; Lamp, William O.; Marbach-Ad, Gili – Journal of Biological Education, 2023
Functional feeding guild classification of aquatic insects is partly based on mouthpart morphology, but the link between mouthpart morphology and ecological feeding roles is often missed by students in the classroom. We implemented a Jigsaw activity in a freshwater biology course to help students connect morphology and ecology. Paired students…

Teasdale, Rachel; Aird, Hannah – Journal of Geoscience Education, 2023
In response to geoscience education research and calls for the need to reform STEM teaching in higher education, many geoscience faculty are adopting research-based pedagogies to improve student learning in their courses. Our own effort to reform our introductory geology course included daily student-centered activities and other reforms we…

Monroe, Christin B. – Journal of Science Education for Students with Disabilities, 2023
Text-to-speech (TTS) technology is a common accommodation available for students with disabilities. Despite the ubiquitous nature of TTS, this technology has not been explored in laboratory settings for neurodiverse college students. This study explores the adaptability of laboratory accessible TTS technology (originally developed for blind/low…

Anoshia Khan; Cristina Altamirano; Yousuf Khan; Haroon Saeed; Tyler Moreira; Troy T. Handlovic; Mohammed R. Elshaer; Justin A. Bogart – Journal of Chemical Education, 2023
Many of the current synthetic methodologies utilized within academic and industrial laboratories require knowledge of how to safely handle air- and moisture-sensitive reagents and work under inert atmospheres. As a result, the ACS Committee on Professional Training recommends incorporating synthetic methods that make use of these inert atmospheres…

Roger W. Giese – Journal of Chemical Education, 2023
The paired-term biochemistry exam comprises five pairs of "unrelated" biochemical terms, where the collection of pairs, overall, is unique for each student. The student selects four of the pairs and answers three short essay questions about each, with a focus on how structure leads to function at the molecular level. Both…

Xiaoqing Liu; Xiaoyan Wang; Xinglong Jin – Journal of Chemical Education, 2023
This paper uses the questionnaire to evaluate the current status of laboratory safety perceptions, willingness, and efforts of first-year undergraduates at the School of Chemistry and Chemical Engineering, Tianjin University of Technology. The survey includes a sample size of 360 undergraduates covering four chemistry-related majors. The…

Qianfu Luo; Chenyu Shi; Zhaoxia Wang; Meng Chen; Da-Hui Qu – Journal of Chemical Education, 2022
Given the importance of self-healing polymers for chemistry education, herein, we introduce our latest research results in self-healing materials based on thioctic acid into undergraduate chemistry laboratory. In this experiment, a natural small molecule, thioctic acid (TA), and a few other commercially-available reagents have been used to make a…

Dutton, Nicole A. M. – American Journal of Distance Education, 2023
An increase in online science course offerings requires a closer evaluation of the online laboratory experience. While it has been established that students can successfully learn from online laboratory simulations, there is a lack of knowledge regarding factors that impact student success. Grounded in the constructivist learning theory, a unique…

Stewart, John F.; Gustafson, John E.; Moore, Michael E.; Forshee, J. Lance; Canaan, Patricia; French, Donald P. – American Biology Teacher, 2023
Students who experience research as undergraduates tend to remain in science, technology, engineering, and mathematics fields. Since course-based undergraduate research experiences (CUREs) are often expensive to implement, we developed a relatively inexpensive first-semester research course for majors entitled "Freshman Research in…

Xinyan Lin; Xiaoshuo Jin; Chunxiu Xu; Heyun Lai; Manbin Lin; Nailin Ren; Longfei Cai – Journal of Chemical Education, 2023
We describe an iodometric titration method for the determination of ascorbic acid using a microfluidic paper-based analytical device([mu]PAD). The ascorbic acid was detected by measuring the length of the blue band formed in a straight paper channel delimited by wax. This analytical method was designed as a laboratory experiment for under…

Alexandria Parker; Evan Noronha; Amanda Bongers – Journal of Chemical Education, 2023
The rise of global environmental issues has stressed the importance of sustainability and green chemistry teachings. Nevertheless, these topics remain largely untouched in most post-secondary organic chemistry lecture courses. This article investigates the barriers to integrating green and sustainable chemistry into organic chemistry classrooms…

Lindén, Johan; Fogde, Anna – Physics Education, 2022
An ordinary soap bubble immersed in a pure carbon-dioxide atmosphere, created e.g. by sublimating chunks of dry ice (solid CO[subscript 2]), will expand within a few minutes to a volume exceeding the original one with a factor of almost ten. Considering that the bubble simultaneously experiences a cooling of ~30 ?C one would perhaps expect a tiny…

Baqi, Younis – Journal of Chemical Education, 2022
A fast, operationally simple, and reproducible synthetic protocol for anthraquinone dyes (AQDs), suitable for upper-division undergraduate industrial and organic chemistry laboratory courses, has been developed. This experiment is composed of three stages; the first step deals with the synthesis of AQDs, followed by a purification step, and…
