基于计算化学的探究式共价键教学设计

Inquiry Teaching Design of Covalent Bond Based on Computational Chemistry

针对共价键教学中存在的问题，探讨了将计算化学技术作为探究工具，引入到共价键探究教学过程中。通过共价键形成过程中轨道重叠程度、键长和体系能量变化等数据，深刻揭示共价键成键的本质，给学生专家级的探究体验。同时强调化学学科方法思想和知识准备的作用，使探究活动更具科学价值。

This paper designed inquiry teaching of covalent bond with computational chemis- try as tools to solve traditional teaching problems. Revealed the essence of covalent bond through the data of orbital overlap degree, bond length and system energy change in the process of forma tion of covalent bond, and gave students expert level inquiry experience. Meanwhile, emphasized the role of chemistry thought and knowledge preparation, and made the inquiry activities more scientific.
