Kizilaslan, Aydin; Sozbilir, Mustafa; Zorluoglu, Seraceddin Levent – Journal of Chemical Education, 2019
Science education could be made more accessible to students with visual impairments through collaboration and specific adaptation in both the science classrooms and laboratories. For example, by providing simple adaptations or doing some essential modifications, students can gain experience with measuring, balancing, and weighing a variety of…

Richard A. R. Blackburn, – Journal of Chemical Education, 2019
Students were asked to each create an infographic on the basis of one of their host department's research articles as a new exercise within the "science communication" training program of the University of Leicester's undergraduate chemistry degree. The use of local articles helped to connect students to the research of their lecturers,…

Herrera-González, Ana M.; Caldera-Villalobos, Martín; Pérez-Mondragón, Alma A.; Cuevas-Suárez, Carlos E.; González-López, J. Abraham – Journal of Chemical Education, 2019
An experiment for the calculation of the degree of double bond conversion, after a polymerization reaction, of photopolymerizable liquid monomers using FTIR-ATR spectroscopy is reported. The experiment was successfully conducted with undergraduate students in materials engineering during the Fundamentals of Polymeric Material course. Students…

Zorrilla, David; Sánchez-Márquez, Jesús; García, Víctor; Fernández, Manuel – Journal of Chemical Education, 2019
Teaching and understanding the concepts related to ideal gases and their transformations is relatively uncomplicated. However, for science and engineering students, reaching an understanding of and assimilating the concepts related to real gases and their transformations is a more difficult goal. Backed by their considerable experience teaching…

Connor, Gannon P.; Kim, Daniel; Nagelski, Alexandra L.; Schmidt, Emily O.; Hass-Mitchell, Tori; Atwater, John T.; Tridenti, Sara A.; Sohn, Seungjung; Holland, Patrick L. – Journal of Chemical Education, 2019
We describe a novel experiment for high school students that uses gas chromatography (GC) equipment to demonstrate the principles of chemical quantitation in the context of fragrant compounds. A highlight of the work is the use of inexpensive equipment and tools accessible to the usual high school laboratory. The students use control samples,…

Cruzeiro, Vinícius Wilian D.; Gao, Xiang; Kleiman, Valeria D. – Journal of Chemical Education, 2019
The ready availability of interactive platforms has produced a new generation of students able to utilize computer-based learning tools with ease and comfort. The potential to better "explore by yourself" the lecture material permits students to have an enhanced learning experience and stimulates them to tinker with equation parameters…

Di Vincenzo, Antonella; Floriano, Michele A. – Journal of Chemical Education, 2019
An application for visualizing the aggregation of structureless atoms is presented. The application allows us to demonstrate on a qualitative basis, as well as by quantitatively monitoring the aggregate surface/volume ratio, that the enhanced reactivity of nanoparticles can be connected with their large specific surface. It is suggested that,…

Mako, Teresa L.; Levine, Mindy – Journal of Chemical Education, 2019
Reported herein is a multidisciplinary experiment for senior-level undergraduate teaching laboratories in the synthesis of the analytes acetaminophen and phenacetin; the fabrication of paper-based devices, using eyeliner, acrylic spray paint, or wax-printing, for sensing of those analytes; and the use of the newly fabricated devices for successful…

Le, Christine M.; Morra, Barbora – Journal of Chemical Education, 2019
The tutorials of a second-year undergraduate organic chemistry course have been modified to include a retrosynthetic exercise in conjunction with a Molecule of the Week (MoW) challenge. In contrast to the original tutorial assignments in the course, which primarily focused on completing simple reaction roadmaps, the new tutorials place a heavier…

Bain, Kinsey; Rodriguez, Jon-Marc G.; Towns, Marcy H. – Journal of Chemical Education, 2019
The themes discussed in this study relate to how students reason about the information encoded in rate constants, which is important for developing a deep understanding of chemical kinetics at the molecular level. This study is part of a larger project centered more generally on students' understanding and use of mathematics in chemical kinetics.…

Mutambuki, Jacinta M.; Fynewever, Herb; Douglass, Kevin; Cobern, William W.; Obare, Sherine O. – Journal of Chemical Education, 2019
Integrating authentic research-based experiences that mimic real-world scientific practices and relevance to student personal life into a chemistry curriculum can make abstract chemical principles more palpable to students. Unfortunately, many reported research-based experiences chemistry laboratory experiments lack relevance to a student's…

Yong, Fang; Zhu, Qiuhong; Zhang, Guohao; Tao, Guohong; Qin, Song – Journal of Chemical Education, 2019
The stated purpose of this paper is to provide a simple and quick method to assemble pH electrodes using readily available materials. The present assembled electrodes are comparable with commercial pH electrodes, with accuracy for pH determination in the range 2-12. Furthermore, the constructed simple pH electrodes exhibit a fast and stable…

Quattrucci, Joseph G. – Journal of Chemical Education, 2018
A new method for teaching advanced laboratories at the undergraduate level is presented. The intent of this approach is to get students more engaged in the lab experience and apply critical thinking skills to solve problems. The structure of the lab is problem-based and provides students with a research-like experience. Students read the current…

Minkiewicz, Piotr; Darewicz, Malgorzata; Iwaniak, Anna – Journal of Chemical Education, 2018
A simple equation to calculate the oxidation states (oxidation numbers) of individual atoms in molecules and ions may be introduced instead of rules associated with words alone. The equation includes two of three categories of bonds, classified as proposed by Goodstein: number of bonds with more electronegative atoms and number of bonds with less…

Hoffmann, Heiko; Tausch, Michael W. – Journal of Chemical Education, 2018
An inexpensive self-made apparatus for photochemical experiments was developed and has been tested to facilitate the inclusion of photoreactions in undergraduate teaching laboratories despite budget constraints. The core setup allowing the selection of defined wavelengths in the visible and UV regions is made of commercially available components…
