从教材结构到课堂运行结构的演化

造成课堂运行结构缺失的原因有两个：一是教材价值及其形态的变化;二是教学脱离教材追求生成性。教材结构制约着课堂运行结构的呈现形态、开发方法与开发步骤。课堂运行结构设计要经历三个层面：一是个性化知识结构的探寻;二是教材活动内容的重组;三是课堂活动的设计。

There are two reasons for the loss of classroom operation structure: one is the changes of teaching material's values and patterns;the other is the pursuit of teaching growth which breaks away from materials.Textbook structure restricts the forms,the developing methods and steps of classroom operation structure,whose design should undergo three levels: the exploration of personalized knowledge structure,the reorganization of teaching activities,and the design of classroom activities.
