数学单元教学设计的内涵、特征以及基本操作步骤

Connotation,Characteristics and Basic Procedures of the Instructional Design of a Unit of Mathematics

数学单元教学设计是在整体思维指导下,从提升学生数学核心素养的角度出发,通过教学团队的合作,对相关教材内容进行统筹重组和优化,并将优化后的教学内容视为一个相对独立的教学单元,以突出数学内容的主线以及知识间的关联性,在此基础上对教学单元整体进行循环改进的动态教学设计。数学单元教学设计具有整体关联性、动态发展性、团队合作性三个基本特征。其操作步骤流程为:确定单元教学内容、分析教学要素、编制单元教学目标、设计单元教学流程以及评价、反思与修改。

The instructional design of a unit of mathematics is a dynamic, systematic and recursive instructional design of a relatively independent unit of mathematics, done collectively within a teaching team under the guidance of holistic principles with the aim of enhancing students＇ core literacy of mathematics. The textbook contents must be restructured and optimized so as to reflect the theme of the teaching contents and link between mathematical knowledge. There are three main characteristics of mathematics unit design, integrity and relevance, dynamic development, and team cooperation. The procedures are as follows, determining the contents, analysis of the teaching elements, setting up the teaching objectives, designing the teaching process, and evaluating, reflecting on and modifying the final procedures.
