Punnoose, Jibin Abraham; Halvorsen, Ken; Chandrasekaran, Arun Richard – Journal of Chemical Education, 2020
There is a disconnect between the cutting-edge research done in academic laboratories, such as nanotechnology, and what is taught in undergraduate laboratories. In the current undergraduate curriculum, very few students get a chance to do hands-on experiments in nanotechnology-related fields, most of which are through selective undergraduate…

Mooney, Madison; Vreugdenhil, Andrew J.; Shetranjiwalla, Shegufa – Journal of Chemical Education, 2020
Green chemistry metrics and life-cycle analysis (LCA) were used to assess inefficiencies in two current organic chemistry experiments conducted in third-year organic chemistry to synthesize ("E")-stilbene from benzaldehyde. An alternative Wittig-based, greener, one-pot experiment using the same starting material was selected as a vehicle…

Logothetis, Thomas A.; Flowers, Colin M. – Journal of Chemical Education, 2020
Whether it is prolonged strike action, a protest movement, or a global viral outbreak, the disruptions triggered in higher education are profound. In a STEM subject, laboratory classes are vital to teaching and learning. Chemistry educators had to transport laboratory skills-based teaching and assessment of courses to the virtual world at short…

Villanueva, Omar; Zimmermann, Kathryn – Journal of Chemical Education, 2020
While the suspension of face-to-face instruction disrupted laboratory components of most chemistry-based classes at the college level, it was notably disruptive to upper-level chemistry courses based solely on laboratory experiences. This communication describes the logistical and pedagogical efforts made in an integrated, upper-level,…

Yuan, Min; Sun, Chun-Yan; Liu, Yi-Wei; Lu, Ying; Zhang, Zhong; Li, Xiao-Hui; Tian, Hong-Rui; Zhang, Shan; Liu, Shu-Xia – Journal of Chemical Education, 2020
A research-style laboratory experiment for advanced undergraduate students is described, which includes the synthesis, characterization, and properties (porosity, stability, amphipathy) testing of the composite [Cu[subscript 2](BTC)[subscript 4/3](H[subscript 2]O)[subscript 2][subscript 6][HPW[subscript 12]O[subscript 40]·(C[subscript…

Kajornklin, Penbhorn; Jarujamrus, Purim; Phanphon, Phuwadon; Ngernpradab, Pakakan; Supasorn, Saksri; Chairam, Sanoe; Amatatongchai, Maliwan – Journal of Chemical Education, 2020
This work reports the first use of rubber latex waste as the hydrophobic reagent for a low-cost, simple, and rapid fabrication of a paper towel-based experimental device (PTED) with a circular design of 5 mm to demonstrate the factors affecting chemical equilibrium; this serves as a user-friendly means for a laboratory experiment. The illustration…

Slade, David J.; Hess, Susan K. – Journal of College Science Teaching, 2020
After a grueling grading campaign, a chemist asked a writing and rhetoric specialist for help improving formal reports in the introductory organic chemistry lab. Together, we realized that the very best student reports employ many persuasive moves in the combined results and discussion subsection, whereas weaker papers omit the persuasive…

Becker, Megan – Journal of Political Science Education, 2020
Undergraduate research experiences (UREs) have been identified as High-Impact Practices that increase understanding of complex concepts, foster independent inquiry, and improve educational outcomes, such as student retention and graduation rates. This article argues that in order to make the URE truly "high-impact," the laboratory model…

Walkup, John R.; Key, Roger A.; Duncan, Sean Patrick; Sheldon, Avery E.; Walkup, Michael A. – Physics Education, 2020
Error analysis consumes much of the focus in introductory physics labs. Catastrophic cancellation is a spike in error that occurs when subtracting two measurements of roughly equal magnitude. Often termed "loss of significance" or "subtractive cancellation," this effect can easily relegate experimental results to utter…

Jackson, Eric S.; Gracco, Vincent; Zebrowski, Patricia M. – Journal of Speech, Language, and Hearing Research, 2020
Purpose: The contextual variability of stuttering events makes it difficult to reliably elicit stuttered speech in laboratory settings. As a result, studies that compare stuttered versus fluent speech are difficult to conduct and, thus, are limited in the literature. The purpose of the current study is to describe a novel approach to elicit…

Azman, Adam M. – Journal of Chemical Education, 2020
Fast, reliable, well-resolved latent fingerprints can be planted by applying a thin coating of a 50:50 mixture of hand lotion and food-grade protein powder. Fingerprints can be revealed with iodine fuming or ninhydrin staining. This low-cost alternative to commercial latent print pads can be used in a variety of classroom or public settings where…

Ren, Jolie; Lin, Tiffany; Sprague, Leonard W.; Peng, Iris; Wang, Li-Qiong – Journal of Chemical Education, 2020
Introducing chemical equilibrium concepts in undergraduate general chemistry promotes improved understanding of chemical reactions. We have developed an engaging laboratory experiment exploring the equilibrium of cobalt complexation in alcohols using UV-vis spectroscopy and successfully implemented in a large general chemistry class of 378…

Hechter, Richard P. – Physics Education, 2020
This article showcases how a Wi-Fi based LED light system that flickers to indicate probability of auroral manifestation became a beacon of inquiry, interest, and critical thinking amongst preservice teachers, staff, and passersby in a teacher education program. Beyond articulating the design phase of the system, highlighted here are the three…

Kate Joy McKnelly – ProQuest LLC, 2020
The dissertation is composed of two main parts. The first half describes efforts to study amyloid peptides using macrocyclic peptide model systems, and the potential deleterious effects of uronium peptide coupling agents on human health. The second half focuses on my experience in chemistry teaching and the chemical education research I conducted.…

Shakerin, Said – Physics Teacher, 2016
A simple mistake in properly setting up a measuring device caused millions of dollars to be spent in correcting the initial optical failure of the Hubble Space Telescope (HST). This short article is intended as a lesson for a physics laboratory and discussion of errors in measurement.
