数学史融入弧度制的教学设计研究

Research on the Teaching Design of Integrating the History of Mathematics into Radian System

摘要: 概念教学是数学教学的重要内容，弧度制作为一个全新的概念，学生在理解和学习中存在一定的难度。从历史上印度数学家阿耶波多设计正弦表遇到的困惑问题，还原产生弧度制的数学意义，重新设计了弧度制的教学情景，力图帮助学生理解弧度制的概念，希望能为教师教学提供参考。

Abstract: Concept teaching is an important part of mathematics teaching. The production of curve is a brand new concept, which makes it difficult for students to understand and learn. Based on the perplexities encountered by Indian mathematician Ayebodo in designing sine table in history, this paper restores the mathematical meaning of radian system and redesigns the teaching scene of radian system, trying to help students understand the concept of radian system, hoping to provide reference for teachers’ teaching.
