A New Learner Model in Adaptive Learning System

Learner model is the core of adaptive learning system and determines the quality of online teaching. Based on online learning norms and combined with learner characteristics of online learning in China, this paper proposes a new learner model. It includes four basic features: basic information, learning style, knowledge state, and cognitive ability. It gives a formal representation of these four feature elements and a method for initializing and updating the values. Finally, in the “Software Engineering” course adaptive learning system developed on the MoodIe platform, the learner model has good usability and validity.
