基于知识地图的中小学个性化在线学习服务模型

Personalized Online Learning Service Model for Students of Primary and Secondary Schools Based on Knowledge Map

摘要: 针对中小学生在线学习过程中存在的学习迷航、认知负荷超载以及学习安排不合理等问题，提出基于学科知识地图的思路进行在线课程内容组织，以及建立在线课程内容资源与学科知识地图中学科知识点之间的关联，然后结合学习者在学科知识点上的学习状态，最终实现个性化的课程内容组织及学习资源推荐服务。论文提出了四环节八步骤的知识地图构建方法，构建了基于知识地图的中小学个性化在线学习服务模型，提出了基于学习者能力水平的学习资源适应度计算方法，并以初中数学学科为例，构建了初中数学学科知识地图，设计了面向初中数学学习的个性化在线学习平台，开发了相应的软件原型系统。

Abstract: Aiming at the problems of learning disorientation, cognitive overload and unreasonable study plan of middle and primary school students in the process of online learning, we propose the idea of online course content organization based on the subject knowledge map. This helps to establish the correlation between online course content resources and subject knowledge points in the subject knowledge map, and with the consideration of the learners’ learning state in the subject knowledge points, we aim to achieve personalized course content organization and provide learning resources recommendation service at last. The paper has put forward a four-stage and eight-step knowledge map construction method, built a personalized online learning service model for middle and primary school students based on the knowledge map, and proposed a learning resources fitness calculation method adapting to the learners’ ability and level. Moreover, with a case study of middle school mathematics, it has constructed a knowledge map of junior middle school mathematics, designed a personalized online learning platform for junior middle school mathematics learning, and developed a corresponding software prototype system.
