Facilitating the Teaching and Learning of Chemistry
The June 2014 issue of the Journal of Chemical Education is now available online to subscribers. The June issue includes articles on using the senses and esters to teach chemistry, developing student-centered activities, introducing the periodic table with puzzles, teaching visual literacy, and exploring thermochromic materials.
Using the Senses and Esters to Teach Chemistry
In the cover article Esterification Reaction Utilizing Sense of Smell and Eyesight for Conversion and Catalyst Recovery Monitoring, Nikki Janssens, Lik H. Wee, and Johan A. Martens describe a simple reaction for demonstrating the use of a homogeneous catalyst in an esterification reaction and observing the catalytic process by two human senses, sight and smell.
Qing Ji, Nadia S. El-Hamdi, and Ognjen Š. Miljanić also use esters in clever combinations to make scent transmutations in order to teach the concepts of chemical equilibrium, distillation, transesterification, dynamic combinatorial chemistry, and the industrially relevant process of reactive distillation
In “This IS NOT Acceptable”, Norbert Pienta (Editor-in-Chief) discusses the appropriateness of student concerns about testing and assessment and of some of the traditions in large-enrollment courses in chemistry education. Deanna Cullen responded to this editorial in her blog post Making the Grade.
