【中文摘要】：
本体作为知识组织的概念模型，是智能教学系统的核心。目前针对一门具体课程的协同本体构建及其应用的研究较少，文章以“教育技术新发展”课程为例，从课程本体的研究现状出发，研究课程知识本体构建的一般方法与步骤，利用学习元平台的功能及特点，实现了课程知识本体的协同构建，探索本体在网络课程中学习资源推荐、课程知识自动标记、学习路径指导、课程可视化导航、个人知识地图、课程资源检索、知识自动问答等方面的实践应用。研究中，本体的建构者也是学习的参与者，在构建课程知识本体的同时，也促进了自身知识的建构；本体采用协同构建方式，引入了“大众”参与，化解了本体建构的难度；本体在学习资源与知识组织方面的多种应用场景，对于提升教学实践有积极作用。
【英文摘要】：
Ontology, as a conceptual model of knowledge organization, is the core component of intelligent tutoring system. At present, a few studies focus on the construction and application of collaborative ontology in a specific course. Starting from the research status of course ontology, this paper takes the course New Development of Educational Technology as an example to demonstrate the general methods and procedures of constructing course knowledge ontology. Based on the function and characteristics of learning cell system, the collaborative construction of the course knowledge ontology is realized. The paper explores the applications of ontology in network courses, including learning resource recommendation, knowledge automatic tagging, learning path guidance, visual navigation, personal knowledge map, resource retrieval, automatic question answer, etc. In this study, the constructors of ontology are also participants of learning, who promote the construction of their own knowledge while constructing the ontology of curriculum knowledge. The ontology adopts the collaborative construction method and introduces the participation of "the mass" to resolve the difficulty of ontology construction. The application of ontology in learning resources and knowledge organization has a positive effect on improving teaching practice.
