The Construction and Evolution of Learner Model in Adaptive Learning System

Abstract

In light of the present situation research on learner model in Adaptive Learning System at home and abroad, this paper has put forward a new learner model to achieve self-organization and push of learning resources on the basis of learning goals and learner’s personal conditions. It includes knowledge level module, cognitive ability module and preferences module. We respectively introduce the representation methods and reasoning mechanisms of the three modules in detail. After that, we introduce the evolution process of learner model. Experimental results show that this learner model is effective and practical in the application.
