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…

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…

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…

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…

Spectrometers play a decisive role in the education of A-level and/or under-graduate students in the field of natural sciences. They are capable to demonstrate atomic emission, transmission, reflection and fluorescence spectra, but can be used for wavelength filtering, as well. Here, we present a do-it-yourself spectrometer setup based on a…

Computational and atmospheric chemistry are two important branches of contemporary chemistry. With the present topical nature of climate change and global warming, it is more crucial than ever that students are aware of and exposed to atmospheric chemistry, with an emphasis on how modeling may aid in understanding how atmospherically relevant…

Providing students with feedback on their performance is a critical part of enhancing student learning in chemistry and is often integrated into homework assignments, quizzes, and exams. However, not all feedback is created equal, and the type of feedback the student receives can dramatically alter the utility of the feedback to reinforce correct…

The retention disparities in undergraduate degree attainment are a persistent problem within the United States, especially for Black, Indigenous, People of Color (BIPOC), first-generation and low-income students, and women (referred to as marginalized groups in STEM [MGS] hereafter) pursuing STEM degrees. The following exploratory article…

Das, K. Rohini; Antony, M. Jinish – Journal of Chemical Education, 2022
For the present lab demonstration, we have developed fluorescent indicators to detect the end point in microscale redox titration of ferrous ions in permanganometry, cerimetry, and dichrometry. Microscale redox titrations were carried out effectively in micromolar(µM) concentrations and semi-microvolumes of the analytes. At the end point,…

An undergraduate laboratory was developed as part of the Drugs for Neglected Diseases "initiative's" Open Synthesis Network. This activity aimed to develop new compounds efficacious against visceral leishmaniasis. Students successfully synthesized, purified, and characterized ten different benzoxazole amides that were sent for biological…

We review the literature, from 2006 to 2020, focused on the teaching and learning of chemical bonding. The studies included in our review (48 studies set in 19 different countries overall) involved secondary and postsecondary students as well as K-12 teachers and university faculty. We synthesize these studies' findings to provide implications for…

Ebert, James R.; Dolphin, Glenn; Bischoff, Paul – Journal of Geoscience Education, 2023
Three cohorts of six pre-service Earth Science teachers (undergraduate majors in Earth Science Education) participated in summer research experiences focused on developing dynamic physical models of Earth processes to help middle and high school students understand complex concepts and confront misconceptions. The pre-service teachers used…

As a universal and extensively adopted technique, enzyme-linked immunosorbent assay (ELISA) can be used to detect and quantify small molecules in many applications both clinical and analytical. However, generally, students experiment mechanically using commercial ELISA kits according to the instructions and eventually produce a standard curve to…

The impact of an interactive in-class Valence-Shell Electron-Pair Repulsion (VSEPR) activity, designed and implemented by the author in her first-year undergraduate chemistry classes, was assessed through the statistical analysis of pre- and posttreatment quizzes on VSEPR theory and the analysis of questionnaires. The activity consisted of…

Quinacridone red and violet are visually different colors, an observation confirmed by their visible reflectance spectra and CIE L*a*b* coordinates. However, their IR spectra are extremely similar. Though chemically identical, the two quinacridones are polymorphs. In this experiment, designed for and tested by nonscience majors, the pigments are…
