Development of teaching material in tablet PC based on computer graphics by quantum chemistry calculation - Walden’s inversion

Abstract

We developed computer graphics (CG) teaching material (TM) for university student, concerned about reaction with drastic change of the structure of reactants in following reaction as a model of Walden’s inversion; OH- + CH3Cl → CH3OH + Cl-. The CG-TM could demonstrate the nature of the reaction by space filling model, ball-and-stick model, and the reaction profile that can provide image of energy change during the reaction. The CG-TM enabled to load with note PC, tablet PC, and smart phone. Practice to the first year or the second year student of Tokyo Gakugei University was conducted. Surveys revealed that the CG-TM in tablet PC was sufficiently effective to provide information about the nature of the Walden’s inversion.
