3D教育游戏在外语教学中的有效性已被众多研究证实，其模拟性、沉浸性和可视化等特点能提升EFL学习者的动机、兴趣和自主性，从而促进语言学习。通过对计算机辅助外语教学文献的梳理，笔者发现国内对3D外语教育游戏的研究较少，国外虽然实证研究较多但较少涉及游戏的任务设计理念。为填补这 一空白，本研究基于Willis(1996）的任务型教学法，为EFL学习者构建了一个3D 教育游戏任务设计框架，涵盖任务前、任务环和语言焦点三个核心环节，并通过应用案例验证了该框架的可行性。最后，本文还从社会环境、学习者特性、学习条件、学习过程和学习成果五个方面阐述了教育游戏与元宇宙相关技术融合如何赋能智慧教育。笔者期望本研究能为任务型教学法的应用带来新思考，为3D外语教育游戏的任务设计提供具体方法，并为智慧教育中的外语教学实践探索数智化途径。

The effectiveness of 3D edugames in foreign language teaching has been extensively verified through numerous studies. Their features of simulation, immersion, and visualization can significantly enhance EFL learners motivation, interest, and autonomy, thereby facilitating language acquisition. A thorough review of literature on Computer-Assisted Language Learning reveals that research on 3D edugames in foreign language learning and teaching is relatively scarce in China, while empirical studies abroad though abundant, seldom delve into the principles of task design in these games. To address this gap, the present study constructs a task design framework for 3D edugames tailored to EFL learners, based on Williss (1996) task-based language teaching (TBLT) approach. This framework encompasses three core stages: pre-task, task cycle, and language focus, and its feasibility is validated through case studies. Moreover, the study explores how the integration of edugames with metaverse-related technologies can empower intelligent education from five perspectives:social context, learner characteristics, learning conditions, learning processes, and learning outcomes. This research aims to provide new insights into the application of TBLT, offer specific methods for designing tasks in 3D educational games, and explore digital approaches for foreign language teaching practice within the realm of intelligent education.
