“空间向量与立体几何”的逆向单元作业设计

Reverse Unit Assignment Design for “Spatial Vectors and Solid Geometry”

摘要: 逆向设计以“目标导向、评价先行”为核心逻辑，契合高中数学核心素养培育与单元整体教学的要求。针对当前高中数学单元作业存在的目标泛化、形式单一等问题，以UbD理论为支撑，构建“分析单元学习内容–设计单元作业目标–研制单元作业评价标准–设计单元作业内容–反馈改进作业内容”的五阶单元作业设计流程，并以“空间向量与立体几何”单元为例，给出了具体的单元作业设计。该研究能实现作业的育人功能，助力学生数学知识体系构建与核心素养发展。

Abstract: Reverse design centers on the logic of “goal-oriented, assessment first”, aligning with the cultivation of core competencies in high school mathematics and the requirements of holistic unit teaching. Addressing current issues in high school mathematics unit assignments, such as overly generalized goals and monotonous forms, this study, supported by the UbD theory, constructs a five-step unit assignment design process: “analyze unit learning content - design unit assignment objectives - develop unit assignment evaluation criteria - design unit assignment content - feedback and improve assignment content”. Taking the unit “Spatial Vectors and Solid Geometry” as an example, a specific unit assignment design is provided. This study can realize the educational function of assignments and help students construct a mathematics knowledge system and develop core competencies.
