| 摘 要： | 角概念的特殊性使得这一概念及其相关内容在数学课程中显示出孤立的特征。通过历史的考察,挖掘出角概念的主要作用在于描述方向的改变,由此进一步了解到凡与方向有关的内容均与角相关联。从历史和文化的视角审视角的度量和角的定义,还可以清晰地发现其中蕴涵着的人文因素以及认知难点,对更好地实现数学史融入数学课程有所裨益。

| Abstract: | The specific feature of the concept of angle and related contents makes them independent in mathematics curriculum.Through the survey of mathematical history,we find that the main function of angle is to describe the change of direction.As a result,all contents related with direction are connected with angle.To view the measurement and definition of angle from the historical perspective,we chould find the factors of humanities and cognitive obstacles of angle,which is helpful for the penetrating of mathematics history into mathematics curriculum. |
