初中数学跨学科教学实践与反思——以《轴对称与轴对称图形》为例

Practice and Reflection on Interdisciplinary Teaching of Junior High School Mathematics—Taking “Symmetry and Symmetrical Figures” as an Example

摘要: 本文以苏科版八年级上册《轴对称与轴对称图形》课堂教学为例，对实践教学进行反思，通过分析课堂实录中的多个教学环节，揭示了如何将数学知识与其他学科内容有机结合，促进学生对轴对称概念的深入理解。同时，文章总结了实际教学中的优势与不足，分别从数学知识、学生学情以及教学目标层面提出相应的改进措施，旨在给后续的数学教学设计提供重要参考和借鉴。

Abstract: This article reflects on practical teaching practices using the “Symmetry and Symmetrical Figures” lesson from the eighth-grade textbook of the Jiangsu Education Edition as a case study. By analyzing multiple instructional segments in classroom recordings, it demonstrates how to organically integrate mathematical knowledge with other subject content to deepen students’ understanding of symmetry concepts. The paper also summarizes strengths and weaknesses in actual teaching, proposing corresponding improvement measures from three perspectives: mathematical knowledge, student learning conditions, and teaching objectives. These insights aim to provide valuable references for future mathematics curriculum design.
