MPCK视角下的余弦定理教学设计

The Teaching Design of Cosine Theorem from the Perspective of MPCK

摘要: MPCK是由数学学科知识、一般教学法知识以及有关数学学习的知识融合而成，此理论框架能为数学教师的教学设计提供指导。文章对MPCK理论框架的概念进行了介绍，并从MPCK视角出发，简述了余弦定理的教学设计过程，最后从MPCK的视角提出数学教师进行教学设计时需注意的三个方面。希望对中学数学教师教学水平的提升有所助益。

Abstract: MPCK is a fusion of mathematics subject knowledge, general pedagogical knowledge and knowledge about mathematics learning. This theoretical framework can provide guidance for mathematics teachers’ teaching design. This paper introduces the concept of MPCK theoretical framework, and briefly describes the teaching design process of cosine theorem from the perspective of MPCK. Finally, from the perspective of MPCK, it puts forward three aspects that mathematics teachers should pay attention to in teaching design. It is hoped that it will be helpful to improve the teaching level of middle school mathematics teachers.
