“AI元宇宙”特指以数字孪生理念构建，由多智能体驱动的、用于跨学科项目化学习的智能交互沙盘环境。针对“黄河改道”主题教学中的知识壁垒高、时空跨度大和学生思维难深化等挑战，本研究基于“数字孪生黄河”理念与地理核心素养导向，设计了以“黄河时空沙盘”为核心的跨学科项目化学习方案。此方案能有效实现抽象知识可视化、离散史料情境化，系统引导学生开展高阶思维活动，有效培育学生地理学科素养，为AI元宇宙技术与地理教学的深度融合提供了可复制的实践范式。

The“AI Metaverse”specifi cally refers to an intelligent interactive sand table environment built on the digital twin concept, driven by multi-agent systems, and designed for interdisciplinary project-based learning. Aiming at the challenges in the thematic teaching of Yellow River Course Changes, including high knowledge barriers, wide spatiotemporal span, and diffi culty in deepening students' thinking, this study designs an interdisciplinary project-based learning scheme centered on the“Yellow River Spatiotemporal Sand Table”, guided by the concept of the“Digital Twin Yellow River”and the orientation of core geography competencies. This scheme can eff ectively realize the visualization of abstract knowledge and the contextualization of discrete historical materials, systematically guide students to carry out higher-order thinking activities, eff ectively cultivate students’geographical key competences, and provide a replicable practical paradigm for the in-depth integration of AI metaverse technology and geography teaching.
