Analysis of the Teaching Contents of “Triangle” from the Perspective of Basic Activity Experience—Taking the Teaching Materials of PEP Edition as an Example

摘要: 基本活动经验的提出，目的是使学生经历知识的形成和再创造过程。本文采用内容分析法和文献研究法，从数学活动的内容分布、数学活动的设计意图这两方面对三角形教材内容中的基本活动经验进行研究。所得结果不仅可以帮助中小学教师理解教材中探究活动的编排意图，还可以为中小学教师合理设计数学探究活动提供一定的理论借鉴。

Abstract: The basic activity experience is proposed to enable students to experience the formation and re-creation of knowledge. This paper uses content analysis method and literature research method, from the following two aspects: the content distribution of mathematical activities, the design intention of mathematical activities, to study the basic activity experience in the content of triangle textbooks. The results can not only help primary and secondary school teachers understand the intention of the arrangement of inquiry activities in the textbook, but also provide some theoretical reference for their rational design of mathematical inquiry activities.
