【摘要】 小学数学跨学科项目式学习作为一种新型教学方法，具有揭示数学多元本质、增强学科之间的联系，弥补抽象数学缺陷、激发学习兴趣和动机，发挥数学学科的育人功能、实现核心素养培育等价值。该研究借助CiteSpace软件对“跨学科”“项目式”相关文献的关键词进行了可视化分析，揭示了目前小学数学领域的跨学科项目式学习研究相对不足的情况。该文从主题构建、目标设定、内容承载、学习路径、学业评价等方面探索小学数学跨学科项目式学习的流程建构，并进行案例设计，旨在落实核心素养的要求，深化课程改革，推动学生全面发展。更多还原

【Abstract】 Elementary mathematics interdisciplinary project-based learning,as a novel teaching method,holds the value of revealing the multifaceted nature of mathematics,enhancing connections between subjects.It compensates for the abstraction of mathematics,stimulates interest and motivation in learning,and utilizes the educational function of mathematics to cultivate core competencies.The paper employs CiteSpace software to conduct a visual analysis of keywords in literature related to "interdisciplinary" and "project-based learning",revealing a relative scarcity of research in the realm of interdisciplinary project-based learning within the field of elementary mathematics education.The Mathematics Curriculum Standards for Compulsory Education explicitly incorporates Nutritious Lunch as a project-based learning theme to be implemented in the third stage of elementary education.Therefore,this paper explores the construction of the process of interdisciplinary project-based learning in elementary mathematics from the aspects of theme construction,objective setting,content delivery,learning pathways,and academic assessment.It also designs a case study based on this process titled "I am a Little Nutritionist," aiming to promote comprehensive student development within an interdisciplinary context,emphasize the potential of interdisciplinary project-based learning in elementary mathematics education,fulfill the requirements of core competencies,and deepen curriculum reform.更多还原
