小学数学跨学科实践性作业设计——以“制定旅游计划”为例

Designing Interdisciplinary Practical Assignments for Elementary School Mathematics—A Case Study of “Planning a Trip”

摘要: 小学数学跨学科实践性作业是促进知识迁移、发展数学核心素养的重要载体。本文基于跨学科学习相关理论，界定跨学科实践性作业的内涵与要素，据此提出数学学科主体性、情境真实性、知识整合性、过程实践性、成果开放性五项设计原则，并形成“确定主题与目标、分析内容与关联、设计情境与任务、配套评价工具”四步设计流程。文章以人教版四年级下册“制定旅游计划”为例，围绕明确问题、收集信息、制定攻略、展示反思四个子任务展开具体设计。

Abstract: Interdisciplinary practical assignments in elementary school mathematics serve as a vital vehicle for promoting knowledge transfer and developing core mathematical literacy. Based on theories related to interdisciplinary learning, this paper defines the essence and key elements of interdisciplinary practical assignments. Accordingly, it proposes five design principles—the centrality of mathematics, the authenticity of contexts, the integration of knowledge, the practicality of the process, and the openness of outcomes—and establishes a four-step design process: “determining themes and objectives, analyzing content and connections, designing contexts and tasks, and developing supporting assessment tools.” Using the “Planning a Trip” activity from the People’s Education Press 4th-grade, second-semester textbook as an example, the article presents a specific design centered on four subtasks: identifying problems, gathering information, developing a plan, and presenting and reflecting.
