Yan, Jianghong; Hu, Shupeng; Xu, Xiudan; Zhao, Dezhang; Wu, Mingjun; Luo, Suxin; Xia, Yong – Biochemistry and Molecular Biology Education, 2018
Medical laboratory technology major was set up to meet rapid development of science and medical research technology in 2013. Students majoring in medical laboratory had learnt a lot of techniques distributed among different specialized courses. But, they did not understand why they had to learn these techniques and how they were applied in a…

Nalliah, Ruth E. – Journal of Chemical Education, 2019
In selecting from a repertoire of traditional kinetics experiments, an instructor often has to choose among having students gain experience with the graphical method, the method of initial rates, or a temperature-dependent experiment in which students construct an Arrhenius plot. This paper presents an environmentally friendly bleaching reaction…

Hudson-Smith, Natalie V.; Cahill, Meghan S.; Klein, Nathan D.; Krause, Miriam O.P.; Haynes, Christy L. – Journal of Chemical Education, 2019
Although nanotechnology lessons are increasingly integrated into curricula, students still face significant challenges in understanding the characterization techniques used to investigate nanotechnology. Many characterization techniques, such as transmission electron microscopy (TEM), are prohibitively expensive for primarily undergraduate…

Sharma, R. K.; Yadav, Subham; Gupta, Radhika; Arora, Gunjan – Journal of Chemical Education, 2019
Systems thinking is highly desirable for re-imagining chemistry education, which will help in the development of an integrated and sustainable approach that takes into account the interdependence of a system under study with other components of the ecosystem rather than practicing a fragmented approach. Thus, to develop a systems' perspective into…

Hiberty, Philippe C.; Danovich, David; Shaik, Sason – Chemistry Education Research and Practice, 2015
This commentary summarizes the authors' basic disagreements with the paper, "Rabbit-Ears, VSEPR Sterics, and Other Orbital Anachronisms," which criticizes the authors' usage of the hybrid orbitals for H[subscript 2]O in their book, "A Chemist's Guide to Valence Bond Theory" (Shaik and Hiberty, 2008). The current article shows…

Aryadoust, Vahid; Foo, Stacy; Ng, Li Ying – Language Testing, 2022
The aim of this study was to investigate how test methods affect listening test takers' performance and cognitive load. Test methods were defined and operationalized as while-listening performance (WLP) and post-listening performance (PLP) formats. To achieve the goal of the study, we examined test takers' (N = 80) brain activity patterns…

Michelle L. Kovarik; Betty Cristina Galarreta; Peter J. Mahon; Daniel A. McCurry; Aren E. Gerdon; Steven M. Collier; Marjorie E. Squires – Journal of Chemical Education, 2022
This article reports the results of a curriculum survey of 322 analytical chemistry instructors (92% U.S.-based) conducted during Spring 2021. This snapshot of current course formats, topics, and pedagogical methods will be useful to both seasoned and novice teachers of analytical chemistry. The majority of respondents reported that their major…

Kondratowicz, Izabela; Z?elechowska, Kamila – Journal of Chemical Education, 2017
The aim of this laboratory experiment is to utilize graphene oxide (GO) material to introduce undergraduate students to many well-known concepts of general chemistry. GO is a new nanomaterial that has generated worldwide interest and can be easily produced in every well-equipped undergraduate chemical laboratory. An in-depth examination of GO…

Tyler, Sarah F.; Judkins, Eileen C.; Morozov, Dmitry; Borca, Carlos H.; Slipchenko, Lyudmila V.; McMillin, David R. – Journal of Chemical Education, 2017
Electronic spectra often exhibit vibronic structure when vibrational and electronic transitions occur in concert. Theory reveals (1) that orbital symmetry considerations determine specific roles played by the nuclear degrees of freedom and (2) that the vibrational excitation is often highly regiospecific, that is, attributable to an identifiable…

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…

Fry, Charles G.; Hofstetter, Heike; Bowman, Matthew D. – Journal of Chemical Education, 2017
Quantitative [superscript 13]C NMR provides a straightforward method of analyzing edible oils in undergraduate chemistry laboratories. [superscript 13]C spectra are relatively easy to understand, and are much simpler to analyze and workup than corresponding [superscript 1]H spectra. Average chain length, degree of saturation, and average…

Sosabowski, Michael Hal; Olivier, George W. J.; Jawad, Hala; Maatta, Sieja – School Science Review, 2017
Natural products are ubiquitous in nature but do not form a large proportion of the A-level syllabuses in the UK. In this article we briefly discuss a small selection of natural products, focusing on alcohols, aldehydes and ketones, and alkaloids. We then outline two natural product experiments that are suitable for A-level chemistry clubs or…

Agnello, Armélinda; Vanberg, Stéphane; Tonus, Céline; Boigelot, Bernard; Leduc, Laurent; Damblon, Christian; Focant, Jean-François – Journal of Chemical Education, 2020
Performing the identification of organic chemical compounds from a set of spectroscopic data gives the opportunity to students to develop critical thinking and problem-solving skills. In this context, we developed a student-centered methodology for teaching molecular structural analysis to first-year undergraduate students. This systematic…

Kovarik, Michelle L.; Clapis, Julia R.; Romano-Pringle, K. Ana – Journal of Chemical Education, 2020
One challenge of teaching chemical analysis is the proliferation of sophisticated, but often impenetrable, instrumentation in the modern laboratory. Complex instruments, and the software that runs them, distance students from the physical and chemical processes that generate the analytical signal. A solution to this challenge is the introduction…
