从“点缀”到“浸润”：初中数学美育的实践路径——以“轴对称”一课为例

From “Ornament” to “Immersion”: The Practical Path of Aesthetic Education in Junior High School Mathematics—Taking the Lesson of “Axial Symmetry” as an Example

摘要: 针对当前初中数学美育实践中普遍存在的将美育窄化为知识教学后“视觉点缀”的困境，文章以“轴对称”一课为例，旨在探索一条使其深度融入学科教学全过程的可操作路径。本文构建了“视觉浸润–触觉浸润–听觉浸润–思维浸润”的四维分析框架，并通过“窗花剪纸”“万花筒制作”“分享交流”“桥梁搭建”等一系列递进式教学活动，具体呈现了美育从零散“点缀”转向全程“浸润”的课堂实践过程。研究表明，这一框架通过激活多感官通道与认知层次，能够有效引导学生经历从感知美、创造美、表达美到理解美的完整审美体验生成过程，将审美体验转化为深刻的意义建构，从而促成数学知识学习与审美素养发展的协同共进。

Abstract: Addressing the common problem of aesthetic education being reduced to mere “visual embellishment” after knowledge teaching in junior high school mathematics aesthetic education practice, this paper takes the lesson “Axial Symmetry” as an example to explore an actionable path for its deep integration into the entire process of subject teaching. It constructs a four-dimensional framework—“visual, tactile, auditory, and thinking immersion”, implements progressive teaching activities such as “paper-cutting”, “kaleidoscope making”, “group discussion”, and “bridge building”, and presents the classroom practice process of aesthetic education shifting from scattered “ornament” to full “immersion”. The results show that this framework guides students through the complete aesthetic experience (perceiving, creating, expressing, and understanding beauty) by activating multiple sensory channels, transforming aesthetic experience into meaningful meaning construction, and fostering the synergistic development of mathematical knowledge learning and aesthetic literacy development.
