Initially, I felt considerable skepticism regarding the suitability of molecular modeling for an introductory course like organic chemistry. Much of this skepticism has proven to be unfounded. I no longer feel that I can teach a good organic course without relying on models. Student feedback has reinforced this feeling. Students request both "eyes-on" and "hands-on" modeling activities. They like to have certain concepts presented using models, and often find models more informative than material in textbook.
Not all modeling-related activities have meshed well with all components of the course, however. Some students fear "hands-on" activities. Students are unable to understand the theoretical basis for modeling because of limited training in physics and quantum mechanics. Also, most of the standard textbook curriculum is based on manipulation of formulas (electron-pushing) and memorization of reagents. These activities do not encourage (or even reward) model use.
