Defining Areas of Interest in Organic Chemistry Education Eye-Tracking Research
Peer reviewed Peer reviewed
Direct linkDirect link
Axel Langner; Lea Sophie Hain; Nicole Graulich – Journal of Chemical Education, 2025
Often, eye-tracking researchers define areas of interest (AOIs) to analyze eye-tracking data. Although AOIs can be defined with systematic methods, researchers in organic chemistry education eye-tracking research often define them manually, as the semantic composition of the stimulus must be considered. Still, defining appropriate AOIs during data…

How to Characterize 4-90 nm Size Gold Nanospheres with Experimental and Simulated UV-Vis and a Single SEM Image
Peer reviewed Peer reviewed
Direct linkDirect link
Josefina Ventre; Agustina L. Renna; Francisco J. Ibañez – Journal of Chemical Education, 2023
It is crucial nowadays to predict in a fast and simple manner physical-chemical behaviors like, the size-dependent optical properties of gold nanospheres (Au NSs). The idea behind this experiment is trying to replace (as much as possible) robust and expensive microscopy techniques with UV-vis spectrophotometry and friendly simulations. Students…

A Refined Redox Titration Simulation Program for the Simple System
Peer reviewed Peer reviewed
Direct linkDirect link
Qiang Fu; Li Liu; Guofu Wang; Jing Yu; Shiyuan Fu – Journal of Chemical Education, 2023
Commonly used methods to simulate the oxidation-reduction (redox) titration curves include the three-step method and the rigorous method. The simple three-step method simulates the redox titration curve with the assumption that the reaction is complete, which is widely used in undergraduate quantitative analysis courses. For the rigorous…

Simulation Game Illustrating the Density-Le Cha^telier Effect on a Chemical Equilibrium of the Type A [equilibrium] 2B
Peer reviewed Peer reviewed
Direct linkDirect link
Thomas Kraska – Journal of Chemical Education, 2022
An educational lattice model is proposed for the investigation of the influence of the density and indirectly of the pressure on the chemical equilibrium of the ideal gas phase reaction A [equilibrium] 2B. The model can be introduced by a board game simulating a stochastic process. This game can also be used to set up a corresponding computer…

Haydon; Karla-Luise Herpoldt; Kandise Van Wormer; Celine Abell; David Baker; Alena Khmelinskaia; Neil P. King – Journal of Chemical Education, 2022
Undergraduate research experiences can improve student success in graduate education and STEM careers. During the COVID-19 pandemic, undergraduate researchers at our institution and many others lost their work-study research positions due to interruption of in-person research activities. This imposed a financial burden on the students and…

Propagation of Significant Figures.
Peer reviewed Peer reviewed
Schwartz, Lowell M. – Journal of Chemical Education, 1985
Shows that the rules of thumb for propagating significant figures through arithmetic calculations frequently yield misleading results. Also describes two procedures for performing this propagation more reliably than the rules of thumb. However, both require considerably more calculational effort than do the rules. (JN)
