Snitynsky, Ryan B.; Rose, Kerry; Pegg, Jerine M. – Journal of Chemical Education, 2019
Since 2015, a partnership between the Canadian Glycomics Network and the University of Alberta's Centre for Mathematics, Science, and Technology Education has provided opportunities for high-school teachers to immerse themselves in academic research environments. Drawing upon this experience, the teacher participants have created a library of…

de Macedo, Adriana Nori; Mathiaparanam, Stellena; Ly, Ritchie; Britz-McKibbin, Philip – Journal of Chemical Education, 2018
New experiments for undergraduate students are needed to stimulate experiential learning in the laboratory while providing valuable training for future career development. Iodine deficiency remains a major public health concern that is monitored by measuring the median urinary iodide concentration of a population. In this context, we have…

Newman, Karla – Journal of Chemical Education, 2018
Almost all commercial quadrupole ICP-MS instruments use collision/reaction cells to either attenuate spectral interferences or shift the analyte of interest to an interference-free "m/z" (e.g., by O addition). A laboratory practical was developed to introduce the students to the basic operating principles of ICP-MS using a hands-on…

Stock, Naomi L. – Journal of Chemical Education, 2017
High-resolution mass spectrometry (HRMS) features both high resolution and high mass accuracy and is a powerful tool for the analysis and quantitation of compounds, determination of elemental compositions, and identification of unknowns. A hands-on laboratory experiment for upper-level undergraduate and graduate students to investigate HRMS is…

Liu, Hanlin; Zaplishnyy, Vladimir; Mikhaylichenko, Lana – Journal of Chemical Education, 2016
A multistep synthesis of thieno[2,3-"b"]pyridine derivatives is described that is suitable for the upper-level undergraduate organic laboratory. This experiment exposes students to various hands-on experimental techniques as well as methods of product characterization such as IR and [superscript 1]H NMR spectroscopy, and…

Flynn, Alison B.; Amellal, Delphine G. – Journal of Chemical Education, 2016
Chemical information literacy is an essential skillset for navigating, evaluating, and using the wealth of print and online information. Accordingly, efforts are underway to improve students' acquisition and mastery of this skillset. However, less is known about students' abilities related to finding and using chemical information to solve…

Bodé, Nicholas E.; Flynn, Alison B. – Journal of Chemical Education, 2016
Organic synthesis problems require the solver to integrate knowledge and skills from many parts of their courses. Without a well-defined, systematic method for approaching them, even the strongest students can experience difficulties. Our research goal was to identify the most successful problem-solving strategies and develop associated teaching…

Asherman, Florine; Cabot, Gilles; Crua, Cyril; Estel, Lionel; Gagnepain, Charlotte; Lecerf, Thibault; Ledoux, Alain; Leveneur, Sebastien; Lucereau, Marie; Maucorps, Sarah; Ragot, Melanie; Syrykh, Julie; Vige, Manon – Journal of Chemical Education, 2016
The rise in carbon dioxide (CO[subscript 2]) concentration in the Earth's atmosphere, and the associated strengthening of the greenhouse effect, requires the development of low carbon technologies. New carbon capture processes are being developed to remove CO[subscript 2] that would otherwise be emitted from industrial processes and fossil fuel…

Duis, Jennifer M.; Schafer, Laurel L.; Nussbaum, Sophia; Stewart, Jaclyn J. – Journal of Chemical Education, 2013
Learning goal (LG) identification can greatly inform curriculum, teaching, and evaluation practices. The complex laboratory course setting, however, presents unique obstacles in developing appropriate LGs. For example, in addition to the large quantity and variety of content supported in the general chemistry laboratory program, the interests of…

Carpenter, Yuen-ying; Phillips, Heather A.; Jakubinek, Michael B. – Journal of Chemical Education, 2010
Chemistry students are often introduced to the concept of reaction rates through demonstrations or laboratory activities involving the well-known iodine clock reaction. For example, a laboratory experiment involving thiosulfate as an iodine scavenger is part of the first-year general chemistry laboratory curriculum at Dalhousie University. With…

King, David; Friend, Jeffrey; Kariuki, James – Journal of Chemical Education, 2010
A pencil lead successfully served as an electrode for the determination of ascorbic acid in commercial orange juice. Cyclic voltammetry was used as an electrochemical probe to measure the current produced from the oxidation of ascorbic acid with a variety of electrodes. The data demonstrate that the less expensive pencil lead electrode gives…
