摘　　要：结合化学平衡复习课的教学现状,分析了化学平衡复习教学的定位和学生的已有认识,阐明了平衡常数是化学平衡复习教学中的核心概念,具有促进平衡知识结构化和解决分析平衡问题思路方法的功能.还进行了发挥核心概念“平衡常数”教学功能的化学平衡复习的教学设计和实践研究,取得了较好的教学效果,探讨了有效的教学策略.This paper analyzes the aim of chemical equilibrium review lessons and students＂ prior knowledge, combining with the actual situation, and concludes that equilibrium constant is a core concept, which has the function of structuralizing all the knowledge related to equilibrium and setting up a useful method of thinking and solving all the problems about equilibrium. More- over, a series of chemical equilibrium review lessons are designed to highlight the value of core concept ＂ Equilibrium Constant＂, the corresponding tests show that the review teaching has a- chieved very good effect, so the effective teaching strategies are discussed.

关 键 词：化学平衡 复习教学 平衡常数 有效教学策略 核心概念
