核心素养视角下的几何模型探究——以“对角互补几何模型”为例

Exploration of Geometric Model Teaching from the Perspective of Core Literacy—Taking the “Diagonal Complementary Geometric Model” as an Example

摘要: 模型是关于对象的一种整体认识，模型化方法是研究数学问题的经典方法，几何模型教学在数学教学中占据非常重要的地位。本文以“对角互补几何模型”的教学为例，围绕核心素养，从旧知回顾、问题提出、模型构建、模型拓展和模型应用五个环节进行教学设计，完善教师教学过程，优化学生探究效果。

Abstract: Models are a holistic understanding of objects, and modeling methods are classic methods for studying mathematical problems, Geometric model teaching plays a very important role in mathematics teaching. This article takes the teaching of the “Diagonal Complementary Geometry Model” as an example, focusing on core competencies, and designing teaching from five aspects: reviewing old knowledge, proposing problems, constructing models, expanding models, and ap-plying models. It aims to improve the teaching process for teachers and optimize the effectiveness of student exploration.
