智慧学习环境中的学习情景识别——让学习环境有效服务学习者

An Approach to Recognize Learning Scenario in Smart Environment

学习情景识别是个性化学习资源推送、学习伙伴联接以及学习活动建议的前提。本文首先分析了学习情景识别所需的六种要素，即学习者模型、学习目标空间、学习活动模型、领域知识模型、时空模型与情景模型，然后提出了一个学习情景识别的概念模型，包含了信息采集、动态建模和情景推理三个模块，并在此基础上讨论了学习者建模、学习活动建模、情景推理等方面的研究进展与关键技术。

Learning scenario recognition is a precondition for a smart learning system to recommend personalized learning resources, to connect learners with others, and to recommend learning activities. This paper analyzes conditions for recognizing learning scenarios, including models of learner, learning activity, domain knowledge, timespace, and learning scenarios. Then,a conceptual model is proposed, consisting of three components: information collection, dynamic modeling, and learning scenario reasoning. Based on this model, recent status and key technologies associated with learner modeling, learning activity modeling, and learning scenario reasoning is introduced.
