知识地图模型及其在教学资源导航中应用研究

The Research of the Knowledge Map Model and the Application in Learning Resources Navigation

数字化学习时代，随着教学资源爆炸式增长，学习者的知识过载问题日益突出。该文针对数字化学习中教学资源的知识化组织和可视化导航与检索问题进行了研究，首先构建了知识地图与资源导航模型，并以此为基础，实现教学资源实体向知识本体的映射；其次，基于知识地图模型，构建学生知识框架，并进行知识可视化；最后，设计与实现了基于知识地图的资源导航与检索系统，基于知识地图的知识隐性关联检索与推荐相关教学资源，实现学习者的个性化推荐与导航。

In digitalization learning time， with the explosive growth of teaching resources， learners’ overloaded knowledge is becoming an extruding problem. On account of that， this paper focuses on digital learning resources of knowledge organization， and problem of visual navigation and retrieval in teaching， firstly we build up knowledge map and navigation model， so that it can implement teaching resources entities to knowledge ontology mapping; secondly， based on the knowledge map model， we construct the student knowledge framework， and make knowledge to be visual; finally， based on knowledge map， we succeed in designation and implementation of the resources navigation and retrieval system; association retrieval of potential knowledge and recommendation of relevant teaching resources， which helps learners to realize personalized recommendation and navigation.
