Fakayode, Sayo O.; Yakubu, Mamudu; Adeyeye, Olasumbo M.; Pollard, David A.; Mohammed, Abdul K. – Journal of Chemical Education, 2014
Diversification of our country's science talent pool is critically needed and can only be achieved by stimulating interest in science, technology, engineering, and mathematics (STEM) among students from a wide variety of cultural backgrounds. However, motivating, increasing the number, improving retention rates, and graduation rates of…

Fakayode, Sayo O.; Pollard, David A.; Snipes, Vincent T.; Atkinson, Alvin – Journal of Chemical Education, 2014
Development of an effective strategy for promoting science education and professional development of K-12 science educators is a national priority to strengthen the quality of science, technology, engineering, and mathematics (STEM) education. This article reports the outcomes of a Geoscience Professional Development Program (GPDP) workshop…

Raker, Jeffrey R.; Reisner, Barbara A.; Smith, Sheila R.; Stewart, Joanne L.; Crane, Johanna L.; Pesterfield, Les; Sobel, Sabrina G. – Journal of Chemical Education, 2015
A national survey of inorganic chemists explored the self-reported topics covered in foundation-level courses in inorganic chemistry at the postsecondary level; the American Chemical Society's Committee on Professional Training defines a foundation course as one at the conclusion of which, "a student should have mastered the vocabulary,…

Daina, Antoine; Blatter, Marie-Claude; Gerritsen, Vivienne Baillie; Palagi, Patricia M.; Marek, Diana; Xenarios, Ioannis; Schwede, Torsten; Michielin, Olivier; Zoete, Vincent – Journal of Chemical Education, 2017
Due to its impact on society, the design of new drugs has the potential to interest a wide audience, and provides a rare opportunity to introduce several concepts in chemistry and biochemistry. Drug design can be seen as a multiobjective cyclic optimization process. Indeed, it is important to develop the understanding not only that a drug is…

Glaser, Rainer E.; Delarosa, Marco A.; Salau, Ahmed Olasunkanmi; Chicone, Carmen – Journal of Chemical Education, 2014
Mathematical methods are described for the determination of steady-state concentrations of all species in multiequilibria systems consisting of several acids and their conjugated bases in aqueous solutions. The main example consists of a mixture of a diprotic acid H[subscript 2]A, a monoprotic acid HB, and their conjugate bases. The reaction…

Rossi, Robert D. – Journal of Chemical Education, 2015
Improving student engagement in STEM (science, technology, engineering, and mathematics) courses generally, and organic chemistry specifically, has long been a goal for educators. Recently educators at all academic levels have been exploring the "inverted classroom" or "flipped classroom" pedagogical model for improving student…

Gan, Li-Hua – Journal of Chemical Education, 2008
Twelve pentagons are sufficient and necessary to form a fullerene cage. According to this structural feature of fullerenes, we propose a simple and efficient method for the construction of I[subscript h] symmetrical fullerenes from pentagons. This method does not require complicated mathematical knowledge; yet it provides an excellent paradigm for…

Williams, Antony J.; Pence, Harry E. – Journal of Chemical Education, 2011
Cell phones, especially "smart phones", seem to have become ubiquitous. Actually, it is misleading to call many of these devices phones, as they are actually a portable and powerful computer that can be very valuable in the chemistry classroom. Currently, there are three major ways in which smart phones can be used for education. Smart phones…

Velasco, Jonathan B.; Knedeisen, Adam; Xue, Dihua; Vickrey, Trisha L.; Abebe, Marytza; Stains, Marilyne – Journal of Chemical Education, 2016
Chemistry laboratories play an essential role in the education of undergraduate Science, Technology, Engineering, and Mathematics (STEM) and non-STEM students. The extent of student learning in any educational environment depends largely on the effectiveness of the instructors. In chemistry laboratories at large universities, the instructors of…

Kerber, Robert C. – Journal of Chemical Education, 2006
The phenomenon under the name "resonance," which, is based on the mathematical analogy between mechanical resonance and the behavior of wave functions in quantum mechanical exchange phenomena was described. The resonating system does not have a structure intermediate between those involved in the resonance, but instead a structure which is further…

Hennigan, Jennifer N.; Grubbs, W. Tandy – Journal of Chemical Education, 2013
The chemical elements present in the modern periodic table are arranged in terms of atomic numbers and chemical periodicity. Periodicity arises from quantum mechanical limitations on how many electrons can occupy various shells and subshells of an atom. The shell model of the atom predicts that a maximum of 2, 8, 18, and 32 electrons can occupy…

Galban, Javier – Journal of Chemical Education, 2004
A simplified mathematical model for the calculation of imprecision associated with the construction of a calibration line is presented. The model also aims at a discussion on variables that really affect it and to integrate the resulting imprecision with that caused by the other steps in the analytical method in order to calculate a real…

Bruce, Mitchell R. M.; Wilson, Tiffany A.; Bruce, Alice E.; Bessey, S. Max; Flood, Virginia J. – Journal of Chemical Education, 2016
In this experiment, students build a spectrometer to explore infrared radiation and greenhouse gases in an inquiry-based investigation to introduce climate science in a general chemistry lab course. The lab is based on the exploration of the thermal effects of molecular absorption of infrared radiation by greenhouse and non-greenhouse gases. A…

Abriata, Luciano A. – Journal of Chemical Education, 2011
A simple algorithm was implemented in a spreadsheet program to simulate the circular dichroism spectra of proteins from their secondary structure content and to fit [alpha]-helix, [beta]-sheet, and random coil contents from experimental far-UV circular dichroism spectra. The physical basis of the method is briefly reviewed within the context of…

Jones, Angela R.; Anderson, Ashley A.; Yeo, Sara K.; Greenberg, Andrew E.; Brossard, Dominique; Moore, John W. – Journal of Chemical Education, 2014
Nanotechnology is an emerging technology poised to benefit society both technically and socially, but as with any new advance, there is potential risk. This paper describes a novel deliberative exercise involving nanotechnology that engages the public in debate regarding the funding of nanotechnology-related research while also discussing…
