泛在学习环境中的学习资源设计与共享——[学习元]的理念与结构

Learning Resource Designing and Sharing in Ubiquitous Learning Environment ——The Concept and Architecture of Leaning Cell

继积件、学习对象和学习活动技术之后，学习资源的建设与共享又呈现出新的发展趋势，如学习过程性信息的共享、资源智能性的挖掘、学习内容的进化发展以及Web2.0理念指引下的[以人为本，群建共享”的资源建设模式等。为了满足未来泛在学习对学习资源生成与进化、智能与适应等多方面的需求，本文提出了适合泛在学习环境与非正式学习的一种新型学习资源组织方式——学习元。它具有生成性、开放性、联通性、可进化发展、智能性、内聚性、自跟踪、微型化等基本特征，可以实现学习者群体智慧的共享和学习工具的共享，学习元是普适计算技术支持的无缝学习空间重要构成要素，是泛在学习实现的基石之一。

With the spread of latest learning technologies such as IntegrableWare， Learning Object and Learning Design， new tendencies are emerging in the constructing and sharing of learning resource. These tendencies include: to share information related to learning processes; to enhance the intelligence of resource; to develop learning content; and to create a new resource construction mode using Web 2.0 principles. In this paper， a learning resource framework called Learning Cell is analyzed. Learning cells were proposed to address certain demands of ubiquitous learning for learning resources to be generative， evolving， intelligent and adaptive. Learning cell will be adapted to u-Learning and informal learning environments. It has the following basic characteristics: generative， open， connective， evolving， intelligent， cohesive， self-tracing and granular. Learners could benefit from shared knowledge in the learner community and the various tools of learning peers use. Learning Cell is a significant element in future seamless learning space supported by ubiquitous computing technology， and will probably be the cornerstone in ubiquitous learning.
