基于UbD理论的高中数学逆向单元教学设计

High School Mathematics Reverse Unit Teaching Design Based on UbD Theory

摘要: 高中数学课程改革要求重视学科大概念，学科大概念是UbD理论的基本要素，而UbD理论提出的逆向教学设计是落实高中数学课程改革的重要途径。基于UbD理论的逆向单元教学设计强调理解和逆向，能够帮助教师专业发展的同时促进学生对知识的真正理解，在此基础上设计多元化的教学方法丰富高中数学教学设计的理论知识。本研究将UbD理论中的大概念、理解六侧面、基本问题、评估与反馈及WHERRTO元素与逆向教学设计的三阶段融合起来对“平面向量及其应用”单元进行温和有序重构，进而得到平面向量及其应用的逆向单元教学设计。本研究旨在为一线教师提供参考，同时促进学生的深度学习和数学核心素养培养。

Abstract: The curriculum reform of high school mathematics requires emphasis on the concept of subject, which is the basic element of UbD theory, and the reverse instructional design proposed by UbD theory is an important way to implement the curriculum reform of high school mathematics. The reverse unit teaching design based on UbD theory emphasizes understanding and reverse, which can help teachers’ professional development and promote students’ real understanding of knowledge. On this basis, diversified teaching methods are designed to enrich the theoretical knowledge of high school mathematics teaching design. In this study, big concepts in UbD theory, six aspects of understanding, basic problems, evaluation and feedback, WHERRTO element and three stages of reverse instructional design are integrated to gently and orderly reconstruct the unit of “plane vector and its application”, so as to obtain the reverse instructional design of plane vector and its application. The purpose of this study is to provide reference for frontline teachers and promote students’ deep learning and core literacy cultivation of mathematics.
