Adams, William; Sonntag, Matthew D. – Journal of Chemical Education, 2018
Recent advances in spectroscopy and computational chemistry facilitate the introduction of current spectroscopic and computational methods at the undergraduate level. Students obtain and analyze experimental and calculated vibrational spectra (infrared and Raman) of a set of alkyne molecules to determine the role of symmetry with respect to gross…

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…

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…

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…

Leslie, J. Michelle; Tzeel, Benjamin A. – Journal of Chemical Education, 2016
A guided inquiry-based experiment exploring the regioselectivity of the hydration of phenylacetylene is described. The experiment uses an acidic gold(III) catalyst in a benign methanol/water solvent system to introduce students to alkyne chemistry and key principles of green chemistry. The experiment can be easily completed in approximately 2 h,…

Ferry, Alissa L.; Fló, Ana; Brusini, Perrine; Cattarossi, Luigi; Macagno, Francesco; Nespor, Marina; Mehler, Jacques – Developmental Science, 2016
To understand language, humans must encode information from rapid, sequential streams of syllables--tracking their order and organizing them into words, phrases, and sentences. We used Near-Infrared Spectroscopy (NIRS) to determine whether human neonates are born with the capacity to track the positions of syllables in multisyllabic sequences.…

Pallone, A.; Barnes, P. – Physics Education, 2016
Basic understanding of nuclear science enhances our daily-life experience in many areas, such as the environment, medicine, electric power generation, and even politics. Yet typical school curricula do not provide for experiments that explore the topic. We present a means by which educators can use the ubiquitous webcam and inexpensive sources of…
