建构主义学习理论对初中数学教学的启示——以“全等三角形”为例
The Enlightenment of Constructivist Learning Theory on Junior High School Mathematics Teaching—Taking the “Congruent Triangle” as an Example

建构主义学习理论是一种重要的教育学派别，它强调个体对知识的建构过程，认为知识不是从外部输入，而是由学习者自己建构。在初中数学教学中，如何应用建构主义学习理论，激发学生的学习热情和主动性，提高学习效果，是当前教育工作者需要探讨和研究的问题。本文基于建构主义学习理论，探讨了初中数学教学中如何促进学生的自我建构，并提出了一些教学策略和方法，并以全等三角形为例进行具体分析和研究，以期为初中数学教师提供一些思路和建议。
Constructivist learning theory is an important educational school that emphasizes the individual's process of constructing knowledge, believing that knowledge is not input from the outside, but constructed by learners themselves. How to apply constructivist learning theory in middle school mathematics teaching, stimulate students’ learning enthusiasm and initiative, and improve learning effectiveness, is a problem that current educators need to explore and research. This article is based on constructivist learning theory, exploring how to promote students’ self-construction in middle school mathematics teaching, and proposing some teaching strategies and methods. Taking congruent triangles as an example for specific analysis and research, it aims to provide some ideas and suggestions for middle school mathematics teachers.
