杂化轨道理论的逆向实例教学法

Reverse Teaching Method of Hybrid Orbital Theory by Examples

杂化轨道理论是现代价键理论的重要组成部分,也是教学难点之一。文章介绍在杂化轨道理论的教学实践中,不灌输理论,而是从自然界中客观存在的甲烷、乙烯、乙炔的分子组成和结构出发,引导、分析和解释这些物质的特殊分子组成及其结构的形成原因,即采用逆向实例教学法逐步引导归纳出杂化轨道理论。该方法深入浅出,课堂教学效果良好。

Theory of hybrid orbital was a part of modern valence bond theory and it was also a difficult point in the teaching of organic chemistry. The paper introduced the reverse teaching method in the teaching of hybrid orbital theory from examples of the structure of methane, ethylene and acetylene. The method was accepted easily and had good effective.
