研学旅行是连接地理学科知识与真实世界的关键桥梁，而任务驱动型作业作为承载“实践学习—问题解决—素养达成”的核心载体，其设计质量直接决定研学育人的成效。本研究以沪—法中学生联合开展的长江流域研学为案例，探讨了地理研学情境中任务驱动型作业设计的原则、路径与实施保障，并阐述了多站点、多主题、多层级的任务设计策略，为核心素养导向下的地理研学作业设计提供可借鉴的范式。

Study tours serve as a vital bridge linking geographical disciplinary knowledge with the real world. Task-driven assignments, as a core carrier integrating practical learning, problem-solving, and the cultivation of key competences, directly determine the educational eff ectiveness of study tours. Taking the Yangtze River Basin study tour jointly conducted by middle school students from Shanghai and France as a case, this study explores the design principles, implementation paths, and support mechanisms of task-driven assignments in geographical study tour scenarios. It elaborates on the multi-site, multitheme, and multi-level task design strategies, offering a paradigm for reference for the design of geographical study tour assignments oriented toward key competences.
