基于UbD理论的逆向单元教学设计——以高中三角函数单元为例

Reverse Unit Teaching Design Based on UbD Theory—Taking High School Trigonometric Function Unit as an Example

新课标的出台推动着教育的改革,基于UbD理论的逆向单元教学设计是对传统教育模式的一种革新,对教学研究从经验型转向实证型、教学活动从以知识为本转向以核心素养为本,具有高度的理论意义和实践意义。以UbD理论的核心思想为依据,通过对高中三角函数单元的大概念、基本问题、评估证据的筛选,进行单元教学设计,旨在为高中数学教学更好的融入追求理解的教学设计理念提供参考和借鉴。

The introduction of the new curriculum standards has promoted the reform of education. The reverse unit teaching design based on UbD theory is an innovation to the traditional education mode, which has a high theoretical and practical significance for the transformation of teaching research from experience-based to empirical and teaching activities from knowledge-based to core literature-based. Based on the core idea of UbD theory, through the screening of the big concepts, basic problems and evaluation evidence of trigonometric function units in senior high school, the teaching design of unit is carried out, aiming at providing reference and reference for the teaching design concept of pursuing understanding in senior high school mathematics teaching.
