Siddiqui, Khawar S.; Poljak, Anne; Ertan, Haluk; Bridge, Wallace – Biochemistry and Molecular Biology Education, 2022
Determination of enzyme activity is crucial for discovery, research, and development in life sciences. The activity of enzymes is routinely determined using spectrophotometric assays that measure rates of substrate consumption or product formation. Though colorimetric-based detection systems are simple, rapid, and economical to perform, the…

Lee, Heejin; Chen, Yu; Lee, Jiwon; Moon, Su Jin; Kim, Jung Bog – Physics Education, 2022
We have developed new rotors that can be classified into three groups by changing the rotors used in simple motors into various types. Group I has a semicircular shape rather than a perfect circle or square shape, group II has a structure consisting of several closed circles on one plane, and group III has a three-dimensional shape. We wanted to…

Cross, Rod – Physics Education, 2022
The trajectory of a ball rolling across an inclined plane was recorded on video film to determine if it followed a parabolic path as others have suggested. The challenges in this case were (a) to determine the magnitude and direction of the friction force on the ball, (b) to determine the effect of the friction force on the trajectory and (c) to…

Aleksey Bychkov; Anna Matveeva – Journal of Chemical Education, 2022
A comprehensive laboratory work that allows students to gain hands-on skills in energy-efficient mechanochemistry is described. Standard university curricula are paying very little attention to mechanochemistry, although skills in this discipline are highly demanded among chemistry graduates. In this study, a comprehensive description of…

Pablo Antonio Archila; Carlos Forero; Anne-Marie Truscott de Mejía; Silvia Restrepo – International Journal of Science Education, 2024
The internationalisation of higher education as well as the emergence of evidence for the claim that bi/multilingualism in science should be the norm, not just an option, are conditions that explain the rise in university bilingual science courses. Thus far, however, little is known about how to foster bilingual scientific argumentation in this…

Angela Bassoli – Journal of Chemical Education, 2024
Organic molecules are invisible objects, but they can be visualized and manipulated by using molecular models. The object-based learning (OBL) approach, which is an educational tool developed for museums and collection items, is tailored and applied to a first-year bachelor course of organic chemistry. At the beginning of the course, each student…

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…

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…
