Kjonaas, Richard A.; Fitch, Richard W.; Noll, Robert J. – Journal of Chemical Education, 2017
A microscale isotopic labeling experiment is described for the introductory organic chemistry laboratory course wherein half of the students use sodium borohydride (NaBH[subscript 4]) and the other half use sodium borodeuteride (NaBD[subscript 4]) to reduce acetophenone to 1-phenylethanol and then compare spectral data. The cost is reasonable, and…

Hie, Liana; Chang, Jonah J.; Garg, Neil K. – Journal of Chemical Education, 2015
A modern undergraduate organic chemistry laboratory experiment involving the Suzuki-Miyaura coupling is reported. Although Suzuki-Miyaura couplings typically employ palladium catalysts in environmentally harmful solvents, this experiment features the use of inexpensive nickel catalysis, in addition to a "green" alcohol solvent. The…

Avargil, Shirly – Journal of Science Education and Technology, 2019
Chemistry curriculum should account for learning in context and understanding chemistry at the macroscopic and microscopic levels: the symbol level and the process level. The "Taste of Chemistry" learning module, developed for high school chemistry majors (students who choose to study the advanced chemistry program in high school),…

Hike, Nina; Beck-Winchatz, Bernhard – Science Teacher, 2015
Many students probably know something about space from playing computer games or watching movies and TV shows. Teachers can expose them to the real thing by launching their experiments into near space on a weather balloon. This article describes how to use high-altitude ballooning (HAB) as a culminating project to a chemistry unit on experimental…

Demircioglu, Gökhan – Journal of Education and Training Studies, 2016
The main purpose of this study is to design an interactive non-formal chemistry environment and investigate its effectiveness on high school students' attitudes towards chemistry. Besides that, it is tried to determine to what extent students correlate these concepts with daily life. 14 voluntary students (5 female, 9 male) from different levels…

Bongers, Amanda; Beauvoir, Berthorie; Streja, Nicholas; Northof, Georg; Flynn, Alison B. – Chemistry Education Research and Practice, 2020
In chemistry, novices and experts use mental models to simulate and reason about sub-microscopic processes. Animations are thus important tools for learning in chemistry to convey reaction dynamics and molecular motion. While there are many animations available and studies showing the benefit of learning from animations, there are also limitations…
