建构主义理论在中学数学教学应用——以三角形内角和定理为例

Application of Constructivism Theory to Secondary School Mathematics Teaching—An Example of the Triangle Interior Angle Sum Theorem

摘要: 建构主义理论强调个体在已有知识基础上主动构建新知识。中学数学教师需要重视学生主体地位，引导学生理解数学本质，鼓励学生在情境中主动学习，将所学知识运用到实际中，培养解决问题的能力。根据《中学数学课例分析》中的“三角形内角和定理”课例分析，对其中课堂呈现不足的地方进行补充，为建构主义融入中学数学提供参考。

Abstract: The theory of constructivism emphasizes that individuals actively construct new knowledge on the basis of existing knowledge. Secondary school mathematics teachers need to pay attention to the student’s main position, guide students to understand the nature of mathematics, encourage students to learn actively in the context, apply what they have learned in practice, and develop problem-solving skills. According to the analysis of the “triangle interior angle and theorem” in the “Secondary Mathematics Case Study”, the classroom presentation of which is insufficient to add, for the integration of constructivism into secondary school mathematics to provide reference.
