基于知识元的移动学习资源组织模式研究

Research on Knowledge Element-based Organization Model of Mobile Learning Resources

移动学习存在着学习资源分散无序、聚合性不足等问题,而引入知识元可构建完整的知识体系,使知识获取效率更高。本研究在综述移动学习资源组织现状、知识元概念和内涵的基础上,确定了知识元的粒度为可编码的"术语""分类与类目""算法""策略"等;进而提出基于知识元"抽取—标引—链接—表征"的移动学习资源组织模式,多维动态表征知识元属性;最后,通过"吴地文化传承"微信公众平台实现了该模式的应用。实践证明:基于知识元的移动学习资源组织模式可应用于知识检索、知识推荐和知识可视化等多个领域。

In mobile learning, because of the resources distributed disorderly and insufficiently, once knowledge element is used, a complement knowledge system can be built to make knowledge acquisition more efficient. Based on the review of the present status of the organization of mobile learning resources and the concept of knowledge element, the particle size of knowledge element is determined as ＂terminology＂,＂classifieation and eategory＂,＂algorithm＂ and ＂ strategy＂. Then a knowledge element-based organization model of mobile learning resource is put forward to represent the properties of knowledge elements, which is described as ＂extraction- index- link- representation＂. Finally, the model is applied to ＂Wu Cultural Heritage＂ WeChat public platform. The study results prove that the model can be applied to various fields such as knowledge retrieval, knowledge recommendation and knowledge visualization as well.
