Murphy, Kevin V.; Turney, Justin M.; Schaefer, Henry F., III. – Journal of Chemical Education, 2018
Preceding even the Hartree-Fock method, molecular integrals are the very foundation upon which quantum chemical molecular modeling depends. Discussions of molecular integrals are normally found only in advanced and technical texts or articles. The objective of the present article is to provide less experienced readers, or students in a…

Rossi, Robert D. – Journal of Chemical Education, 2013
Many students find the transition from first-year general chemistry to second-year organic chemistry a daunting task. There are many reasons for this, not the least of which is their lack of a solid understanding and appreciation of the importance of some basic concepts and principles from general chemistry that play an extremely critical role in…

Martineau, Eric; Boisvert, Louise – Journal of Chemical Education, 2011
Wikipedia represents a revolution in the way knowledge is communicated and a potential threat to traditional encyclopedias. Wikipedia is widely used as a reference in academic assignments. Unfortunately, for the neophyte, it may be hard to assess the completeness and the accuracy of a contribution to Wikipedia. In this article, we describe an…

Pursell, David P. – Journal of Chemical Education, 2009
Students of organic chemistry traditionally make 3 x 5 in. flash cards to assist learning nomenclature, structures, and reactions. Advances in educational technology have enabled flash cards to be viewed on computers, offering an endless array of drilling and feedback for students. The current generation of students is less inclined to use…
