Research on Learner Portrait Based on xAPI and Learning Analysis

At present, the deep integration of technology and education has become the focus of researchers. In order to better apply information technology to online learning and provide technical support for personalized learning. This paper constructs learner portrait model from four dimensions: personal information, learning style, behavioral characteristics and learning performance. According to xAPI standard, learning behavior activity flow is designed to collect learning data, extract learning behavior tags and build learner portrait. Finally, the overall analysis and group analysis of learner portrait are carried out with the help of learning analysis, so as to provide personalized and accurate online learning support services for learners and improve learning efficiency and quality.
