【摘要】 本文以《普通高中数学课程标准（2017年版2020年修订）》以及相关教育教学改革政策为依据，针对高中数学教学中跨学科融合与实践能力培养的现实需求，构建基于项目式学习的高中数学跨学科实践活动设计框架。以“纸扇中的数学”为实证案例，教学设计依托新闻情境导入课题，围绕“优化纸扇风力与扇面面积”核心问题，引导学生整合数学、物理、美学等多学科知识，借助动态教学软件开展定量探究，并通过成果二次创作与互评完善实现认知深化。研究表明，该实践模式能有效促进学生数学核心素养的内化，显著提升其问题解决能力、知识迁移能力与跨学科应用素养，为高中数学跨学科教学的创新实施提供了可借鉴的实践范式。更多还原

【Abstract】 Based on the General Senior High School Mathematics Curriculum Standards(2017 Edition, Revised in 2020) and educational and teaching reform policies, this paper constructs a design framework for interdisciplinary practical activities in senior high school mathematics, in response to the practical needs of interdisciplinary integration and practical ability cultivation in senior high school mathematics teaching. Taking “Mathematics in Paper Fans” as an empirical case, the teaching design introduces the topic through a news context, centers on the core issue of “optimizing the wind force and surface area of paper fans”, guides students to integrate knowledge from multiple disciplines such as mathematics, physics, and aesthetics, conducts quantitative exploration with dynamic teaching software, and deepens cognition through secondary creation and mutual evaluation of the results. Research shows that this practical model can effectively promote the internalization of students’ core mathematical literacy, significantly enhance their problem-solving ability, knowledge transfer ability, and interdisciplinary application literacy, providing a practical model for the innovative implementation of interdisciplinary teaching in senior high school mathematics.更多还原
