ON Heterogeneity in Instructional Design

"同课异构"是教师根据学习者特征、教学内容特征和教师自身的特点进行个性化的教学设计。文章旨在分析影响中学英语"同课异构"的因素,建立学习者、教学内容和教学目标要素的分析体系,即横向和纵向分析维度体系。在此基础上,提出了"同课异构"课堂教学案例对比分析体系,主要包括学习前、学习中和学习后这三个主要课堂教学步骤中的"异构"。从案例对比分析可知,影响"同课异构"的根本因素是教学模式的选择。

Heterogeneity in instructional design refers to the instruction of the same teaching content in diversified ways. The author proposes that the framework of analysis includes learners’ analysis, teaching content analysis and objective analysisin terms of vertical and horizontal dimensions. Furthermore, the contrastive study of cases of heterogeneity is conducted in the stages of pre-class, while-class and post-class. The conclusion is drawn that the fundamental factor contributing to heterogeneity in ID is the manipulation of class-room teaching models. And the Scaffolding Instruction is suggested as an option in innovation in classroom teaching.
