概念变式的设计流程是:收集错题→分析错题→确定目标→设计变式.1.收集错误.错误不是教给的,是学习者构造了自己特有的概念与程式造成的.所以教师要充分利用错误这个教学资源,它了解学生已对概念的掌握程度.这一步主要工作就是对学生常见错误收集,并根据概念的类别进行分类.2.分析错误.这一步主要是为了了解学生对概念本质属性(相关特征)的掌握情况.学生经常出现错误 Conceptual variant design flow is: Collect the wrong question → Analyze the wrong question → Determine the goal → Design Variables .1. Collecting mistakes. Errors are not taught, is the learners to construct their own unique concepts and programs caused. So the teacher To make full use of the error of this teaching resource, it is to understand the students have mastered the concept.The main task of this step is to collect common mistakes students, and according to the classification of concepts.2 analysis of errors.This step is mainly to understand the students The mastery of the nature of the concept (related features). Students often make mistakes
