Dias, Lucas A. L.; Faria, Roberto B. – Journal of Chemical Education, 2020
The use of symmetry is widespread in chemistry, as it is used for predictions of the number of allowed and forbidden absorptions in electronic, vibrational, and rotational spectroscopies; for predictions of the combination of atomic orbitals to produce molecular orbitals; and in many other chemical applications. One critical step in these…

Magalhães, Alexandre L. – Journal of Chemical Education, 2020
A bachelor's degree program in chemistry typically starts with basic concepts in mathematics, physics, and chemistry. Those principles are very important because they pave the ground for future advanced studies and, therefore, one needs to present them in a clear but rigorous way. One example is provided by the mathematical notion of an iterative…

Argu¨ello, Jose´ M.; Dempski, Robert E. – Journal of Chemical Education, 2020
Facile visualization of biomolecules is an essential component of the undergraduate biochemistry curriculum. In the past, a number of tools have been used to display biomolecules. More recently, the advent of greater accessibility to virtual reality (VR) and augmented reality (AR) programs has created a new mechanism to visualize biomolecules.…

Haworth, Naomi L.; Martin, Lisandra L. – Journal of Chemical Education, 2018
A series of computer-based laboratory experiments have been developed to aid undergraduate students in appreciating the three-dimensional nature of chemistry and biochemistry. Both lower- and upper-division experiments have been developed. Students are introduced to the use of ChemDraw for the production of professional-quality molecular…

Camrud, Evan; Turner, Daniel B. – Journal of Chemical Education, 2017
Numerous computational and spectroscopic studies have demonstrated the decisive role played by nonadiabatic coupling in photochemical reactions. Nonadiabatic coupling drives photochemistry when potential energy surfaces are nearly degenerate at avoided crossings or truly degenerate at unavoided crossings. The dynamics induced by nonadiabatic…

Saputra, Andrian; Canaval, Lorentz R.; Sunyono; Fadiawati, Noor; Diawati, Chansyanah; Setyorini, M.; Kadaritna, Nina; Kadaryanto, Budi – Journal of Chemical Education, 2015
Quick and real-time plotting equations using the Winplot software can be employed to create accurate hybrid atomic orbitals without complicated scripting. Performing this task on their own, students can more easily understand and remember hybrid atomic orbitals, in terms of shape and orientation.

Petrovic, Dus?an; Zlatovic´, Mario – Journal of Chemical Education, 2015
A homology modeling laboratory experiment has been developed for an introductory molecular modeling course for upper-division undergraduate chemistry students. With this experiment, students gain practical experience in homology model preparation and assessment as well as in protein visualization using the educational version of PyMOL…

Venkataraman, Bhawani – Chemistry Education Research and Practice, 2009
A series of interactive, instructional units have been developed that integrate computational molecular modelling and visualization to teach fundamental chemistry concepts and the relationship between the molecular and macro-scales. The units span the scale from atoms, small molecules to macromolecular systems, and introduce many of the concepts…

Chong, Cordelia – Teaching Science, 2009
When students make the transition from one curriculum to another, with significant overlap of content, the challenge is not so much to impart new information but rather to tap into students' existing knowledge base. The purpose of this study was to determine if achievement in an external examination that requires analysis could be enhanced by the…

Fossey, Annabel; Hancock, Carolyn – Biochemistry and Molecular Biology Education, 2005
First-year students in genetics at the University of KwaZulu-Natal, South Africa, attend two general biology modules, one in each semester. Teaching involves four formal lectures per week of 45 min each, one 3-h practical, and one lecture period tutorial. These students, graduating from secondary education, are well schooled in rote learning but…

Journal of Chemical Education, 1988
Reviews two computer programs: "Molecular Graphics," which allows molecule manipulation in three-dimensional space (requiring IBM PC with 512K, EGA monitor, and math coprocessor); and "Periodic Law," a database which contains up to 20 items of information on each of the first 103 elements (Apple II or IBM PC).

Kinderman, Jesusa Valdez – Physics Teacher, 1992
Describes a computer simulation of the Compton effect designed to lead students to discover (1) the relationship of the electron's final kinetic energy to its angle of scattering and (2) the relationship between the scattering angles of the outgoing electron and photon. (MDH)
