Peter F. Lang – Journal of Chemical Education, 2025
The concepts of electronegativity and classical electronegativity scales are briefly described. Electronegativity scales have practical quantitative applications, and this work suggests activities which can assist students select the scales for use in chemistry applications. It provided examples of the use of an appropriate electronegativity…

Mohammad Ali Zolfigol; Saeid Azizian; Morteza Torabi; Meysam Yarie; Behrouz Notash – Journal of Chemical Education, 2024
In chemical synthesis, obtaining product(s) with high purity is a crucial issue from both academic and industrial viewpoints. Higher purity of the product(s) means higher quality and a lower chemical production costs. Sometimes, purification and separation processes are very laborious and lead to significant impacts on the final price of the…

Joseph Salve; Pranshi Upadhyay; K. K. Mashood; Sanjay Chandrasekharan – Science & Education, 2025
Science learning requires students to build new mental models of imperceptible mechanisms (photosynthesis, circadian rhythms, atmospheric pressure, etc.). Since mechanisms are structurally complex and dynamic, building such mental models requires mentally simulating novel structures, their state changes, and higher-order transformations…

Beni B. Dangi; Maggie A. Cooper; Nathaniel Carnegie; Judy Clark – Journal of Chemical Education, 2025
A laboratory experiment has been designed for teaching laboratories aimed at training students in the basics of spectroscopy in junior and senior level undergraduate chemistry courses. Despite the ubiquity of light-based tools in modern science, students often find it difficult to comprehend light and light-matter interactions. A portable…

Caryn Babaian; Sudhir Kumar – American Biology Teacher, 2024
The emerging field of genomic medicine offers an opportunity for biology and anatomy teachers to bring the topics of DNA, genetics, molecular processes, and evolution together into one experience. Through the genomic medicine paradigm, students see the unbroken connection between small biological topics such as mutations and their potential…

Min Han; Jiaxin Zhang; Yiping Wang; Yan Hu; Ronghui Que – Journal of Chemical Education, 2024
A simple, safe, and easy demonstration of the reaction of sodium peroxide with water is presented. The reaction is performed in a plastic bottle by adding water to sodium peroxide supported in a rubber "thimble"; oxygen is detected by the reignition of a glowing splint, while the generation of sodium hydroxide is indicated by…

David C. Owens; Troy D. Sadler – School Science and Mathematics, 2024
Socio-scientific issues (SSI) instruction positions the understanding and practice of science in the context of issues that are informed by science but require reasoning about their societal dimensions to respond to those issues effectively. For this reason, instruction in the context of SSI has been considered the gateway to contemporary visions…

Rafal Fran´ski – Journal of Chemical Education, 2024
The area of application of electrospray ionization mass spectrometry (ESI-MS), usually coupled with liquid chromatography, seems to be much larger than those of any other ionization method. It gives rise to the demand for new teaching methods that would effectively help students to master the principles of working with and making full use of the…

Courtney H. Deslauriers; Benjamin J. Knurr – Journal of Chemical Education, 2024
Experiments that explore quantum principles while utilizing and reinforcing previous synthesis skills are excellent for engaging students and promoting the interconnected nature of chemistry. This experiment utilizes sophomore-level organic synthesis techniques to have students produce their own "meso" substituted porphyrins. The UV-vis…

Philip P. Lampkin; Angie E. Xu; Brian J. Esselman; Cara E. Schwarz; Sebastian D. Thompson; Samuel H. Gellman; Nicholas J. Hill – Journal of Chemical Education, 2024
Synthesis of (Z)-alkenes is challenging because the (E) stereoisomers are usually more stable. Energy transfer photocatalysis has emerged as an efficient strategy for (E) [right arrow] (Z) alkene isomerization. We report the development of an advanced undergraduate laboratory experiment that introduces students to contemporary organic…

Anna Laguta – Journal of Chemical Education, 2025
Colloidal stability is one of the most important criteria in the application strategy of colloidal nanoparticles in the continuous phase. The branches include ecology, involving coagulation as a purification method; medicine as nanocarriers; biology as blood coagulation, etc. A chemist versed in these concepts is a high-performing chemist in…

Valeria Edelsztein; Claudio Cormick – Science & Education, 2025
In this article, we tackle the phenomenon of what seems to be a misunderstanding between science education theory and philosophy of science--one which does not seem to have received any attention in the literature. While there seems to be a consensus within the realm of science education on limiting or altogether denying the explanatory role of…

Hasminar Rachman Fidiastuti; Sri Rahayu Lestari; Suhadi ?; Sitoresmi Prabaningtyas – Journal of Microbiology & Biology Education, 2024
Recently, several articles have reflected on the existence of microorganisms in supporting the life and health of living creatures as the beginning of the emergence of microbiology literacy. In the curriculum, understanding the activity of microorganisms has been studied from pre-school, elementary school, and middle school to college. The…

Lianwen Zhu – Journal of Chemical Education, 2024
A chemistry laboratory experiment is described to introduce undergraduate college students to membrane separation technology. This experiment combines a simple nanowire membrane fabrication and visually indicated molecule separation. The membrane is produced via coprecipitation synthesis followed by a filtration assembly process, which can be…
