摘　　要：共价键理论是化学学科的核心内容,基于认识视角梳理共价键的发展史,将共价键理论的形成和发展分为4个阶段,现象阶段:初识物质结合方式;表征阶段:探索微粒结合过程;本质阶段:揭示共价键形成实质;发展阶段:解释物质结构与性质。共价键历史的发展阶段与教材的编排一脉相承,结合学生的认知发展,有以下教育价值:(1)凸显学科思想方法;(2)持续发展学生认识进阶;(3)促进学生素养形成。Covalent bond theory is the core of chemistry.This paper analyzes the development history of covalent bond from the perspective of cognition,the formation and development of covalent bond theory can be divided into four stages,the phenomenon of phase:preliminary understanding of the way of material combination;characterization of phase:explore the particle bonding process;nature of phase:reveal the essence of covalent bond formation;development phase:explain the structure and properties of matter.The development stage of covalent bond history is in line with the arrangement of teaching materials,combine with students' cognitive development.It has the following educational values:(1)embody the thought and method of subject;(2)continue to develop students' cognitive advancement;(3)to promote the formation of students' literacy.
