【摘要】针对学习资源在吸收集体智慧、持续进化、生成性信息共享、分布式实时共享、社会关系网络共享和智能性要求等方面的发展趋势，我们提出了“学习元”这一新的学习资源组织模型。本文进一步对学习元的运行支撑环境的运行架构、功能设计和内部存储结构作了较为详细的阐释，具体描述了这些元素和功能如何实现对学习元生成性、开放性、联通性、可进化发展、智能性、内聚性、自跟踪、微型化等基本特征的支持，为构建基于学习元的实际应用环境奠定了初步的技术基础。

Abstract: There are several trends in the development and sharing of learning resources, including utilizing collective wisdom, sustaining evolvement, generative information sharing, distributed runtime resource sharing, social network sharing, and intelligent resources. We proposed a new learning resource model called as "Learning Cell", which can be used to meet requirements in the above-mentioned trends. It can also be used to support informal learning and ubiquitous learning. In this paper, we discussed the architecture and functional design of the supporting system and the storage structure for learning cells as the technical bases for learning cell applications.
