Vroom Redden, Alexis M.; Barton, Callie M.; William, Kyle R. – Journal of Chemical Education, 2020
Guided inquiry is the practice of allowing students to come to their own conclusions about a set of data instead of verifying a known result using a given experimental procedure. Open inquiry takes this idea one step further by allowing students to develop their own experiment and then analyze the data to arrive at a conclusion. To expose upper…

Dickson-Karn, Nicole M. – Journal of Chemical Education, 2020
The COVID-19 pandemic forced the conversion of the quantitative chemical laboratory from a face-to-face format to a distance learning format for the latter half of the Spring 2020 semester. This work provides insight into two different types of assignments given to students during this time: a lab report and a short-answer assignment. At the…

Serafin, Joseph M.; Chabra, Jennifer – Journal of Chemical Education, 2020
Rising cases of COVID-19 caused St. John's University to transition to an online educational model in the spring 2020 semester. As a result, an in-person Cooperative Learning advanced general chemistry laboratory course was transitioned into an online/remote Cooperative Learning experience. Cooperative Learning in the general chemistry laboratory…

Strachan, Jyah; Barnett, Christopher; Maschmeyer, Thomas; Masters, Anthony F.; Motion, Alice; Yuen, Alexander K. L. – Journal of Chemical Education, 2020
We report a research-enhanced undergraduate laboratory practical in which students synthesize and characterize color-controllable, stable silver nanoparticles for use in a simple catalytic reaction analyzed by UV-vis spectroscopy. The practical has been prepared for students using electronic laboratory notebooks, enables collaborative data…

Verma, Abha; Goyal, Navneet – Journal of Chemical Education, 2020
A new two-step experiment has been designed and developed for the curriculum of the Organic Chemistry Laboratory 2 (CHEM2240L) sophomore course at Xavier University of Louisiana, in New Orleans. Initially, cyclohexanol was converted to cyclohexanone using bleach as the oxidizing agent followed by the formation of the cyclohexanone oxime. However,…

Li, Dean; Liu, Lilan; Zhou, Shaona – Physics Teacher, 2020
Interest in smartphone-based learning, especially in the use of internal sensors in smartphones for physics experiments, is increasing rapidly. Internal sensors in smartphones such as acoustic sensor, optical sensor, and acceleration sensor can help researchers alleviate the problems including insufficient accuracy with low-cost equipment, high…

Isaac-Lam, Meden F. – Journal of Chemical Education, 2020
Nuclear magnetic resonance (NMR) spectroscopy is an indispensable technique in the organic chemistry laboratory for elucidation of molecular structure. Miniaturization of NMR technology has attracted attention and acceptance due to a considerable reduction in the cost to acquire and maintain the instrument. The advent of low-field, low-cost, and…

Karbowiak, Michal; Wibig, Tadeusz; Alvarez-Castillo, David; Beznosko, Dmitriy; Duffy, Alan R.; Góra, Dariusz; Homola, Piotr; Kasztelan, Marcin; Niedzwiecki, Michal – Physics Education, 2020
The Cosmic-Ray Extremely Distributed Observatory (CREDO) is the project to search and study ultra high-energy cosmic ray particles from deep space producing simultaneous extensive air showers over the entire exposed surface of the Earth. The concept of the CREDO infrastructure assumes absorbing all kinds of cosmic ray data from any apparatus all…

Atkin, Keith – Physics Education, 2020
This paper demonstrates how the transcendental number "e" may be arrived at by observing the discharge of a capacitor through a fixed resistor and then modelling the system using a simple step-wise procedure. The experimental phase makes use of the Arduino microcontroller, while simple modelling of the system is carried out by means of…

Higgins, Pamela J. – Journal of Chemical Education, 2020
Most forensic chemistry experiments focus on the usual suspects involving criminal scenarios: illicit drug identification, gunshot residue detection, blood and fingerprint analysis, and arson investigations. However, environmental forensics involves chemical techniques that can expand the breadth of experience for forensic chemistry students. An…

Kerdkaew, Thitipong; Limpanuparb, Taweetham – Journal of Chemical Education, 2020
To prove that oxygen is irreversibly consumed in the blue bottle reaction, a manometer or a plastic bottle was used to show a permanent reduction in the gas pressure in a reaction vessel. This demonstration may be misleading because the change in gas pressure can be attributed to a number of other factors such as temperature change and involvement…

Lisensky, George; Dauzvardis, Fabian; Luo, Jiaqi; Horger, Jacob; Koenig, Emma – Journal of Chemical Education, 2020
Polymers and nanochemistry are important facets of chemistry. In this experiment, students synthesize monodispersed poly(methyl methacrylate) nanospheres from the addition or chain polymerization of a rapidly stirred aqueous mini-emulsion of methyl methacrylate. The 2,2'-azobis(2-methylpropionamidine) dihydrochloride serves as a heat activated,…

Stilwell, Matthew D.; Yao, Chunhua; Vajko, Dale; Jeffery, Kelly; Powell, Douglas; Wang, Xudong; Gillian-Daniel, Anne Lynn – Science Teacher, 2021
What if "every breath you take, every move you make" (Sting 1983) could be harnessed to produce renewable energy? Triboelectric nanogenerators (TENGs) are state-of-the-art devices researchers are studying to do just that--convert kinetic energy into electrical energy at the source (Saurabh Rathore 2018). This type of electrical energy is…

Mierdel, Julia; Bogner, Franz X. – Research in Science Education, 2021
Genetics is known to be one of the most challenging subjects in biology education because of its abstract concepts and processes. Therefore, hands-on experiments in authentic learning environments are supposed to increase comprehensibility and provide otherwise unavailable experiences to students. We applied a hands-on module in an out-of-school…
