摘要
学习对象已成为国际上流行的学习资源组织形式。使用元数据描述的数字化学习资源可方便实现管理和复用，提高资源管理的效率。本研究重点讨论学习对象的概念及其显著特征，以及设计策略，如聚合度和组合问题，最后探讨资源库开发过程中涉及到的几个问题，如技术上的具体实现方式，并给出层次结构模型。
Learning Object which used meta-data to label themselves so that can be managed and reused easily has become the prevalent formation of learning resource on the world, The study introduce the conception of the learning object and some features, and design strat-egy, such as the problems which Can be aggregated and combined, and finally explore some problems which have relation to the construction of the repository, about a specific technology way of realizing, and give out the level of structure model.
