Zdanovskaia, Maria A.; Schwarz, Cara E.; Habib, Asif D.; Hill, Nicholas J.; Esselman, Brian J. – Journal of Chemical Education, 2018
The use of computational molecular modeling to enhance the teaching of chemical concepts is becoming commonplace. Incorporation of this technique into the curriculum, however, typically requires financial investment. This reality poses a problem for institutions where funding and associated resources are scarce and has a potential negative impact…

Devarajan, Deepa; Gustafson, Samantha J.; Bickelhaupt, F. Matthias; Ess, Daniel H. – Journal of Chemical Education, 2015
Undergraduate organic chemistry textbooks and Internet websites use a variety of approaches for presenting and explaining the impact of halogen atom size on trends in bond strengths and/or acidity of hydrogen halides. In particular, several textbooks and Internet websites explain these trends by invoking decreasing orbital overlap between the…

Wang, Yue; Xu, Xinhua; Wu, Meifen; Hu, Huikang; Wang, Xiaogang – Journal of Chemical Education, 2015
Scanning electron microscopy (SEM) was introduced into undergraduate physical chemistry laboratory curriculum to help students observe the phase composition and morphology characteristics of tin-lead alloys and thus further their understanding of binary alloy phase diagrams. The students were captivated by this visual analysis method, which…

Eklund, Brandon; Prat-Resina, Xavier – Journal of Chemical Education, 2014
ChemEd X Data is an open web tool that collects and curates physical and chemical data of hundreds of substances. This tool allows students to navigate, select, and graphically represent data such as boiling and melting points, enthalpies of combustion, and heat capacities for hundreds of molecules. By doing so, students can independently identify…

Kim, Heejoo; Chacko, Priya; Zhao, Jinhui; Montclare, Jin Kim – Journal of Chemical Education, 2014
As part of an outreach program, we integrated chemistry apps with blogging to enhance the learning experience of students in and outside the classroom. Our outreach program involved college mentors who participated in the development and implementation of chemistry lessons alongside the classroom teacher. Three technology-rich modules that focused…

Williamson, Vickie M.; Lane, Sarah M.; Gilbreath, Travis; Tasker, Roy; Ashkenazi, Guy; Williamson, Kenneth C.; Macfarlane, Ronald D. – Journal of Chemical Education, 2012
A prior study showed that students best make predictions about the outcome of opening a valve between two flasks containing a fluid or vacuum when they view both a demonstration video and a particulate animation, but the study showed no influence from the order in which these visualizations were used. The purpose of this current research was to…

Campbell, Dean J.; Miller, Josiah D.; Bannon, Stephen J.; Obermaier, Lauren M. – Journal of Chemical Education, 2011
LEGO bricks can be used for a number of demonstrations of chemical structures and properties, especially at the nanoscale level. These bricks can also be used to model instrumentation that probes these structures and properties. Detailed resources about many of these demonstrations are located on the extensive Web site "Exploring the Nanoworld…

Battle, Gary M.; Allen, Frank H.; Ferrence, Gregory M. – Journal of Chemical Education, 2010
A series of online interactive teaching units have been developed that illustrate the use of experimentally measured three-dimensional (3D) structures to teach fundamental chemistry concepts. The units integrate a 500-structure subset of the Cambridge Structural Database specially chosen for their pedagogical value. The units span a number of key…
