摘要：In light of the present situation researches on learner model in Adaptive Learning System at home and abroad, analyze the design principles and characteristics of Adaptive Learning System. Based on these, this paper summarizes the main problems of learner model from dimension of attention, representation method and acquisition path. It puts forward a new learner model called Advanced Learner Model (ALM for short), which includes three characteristic items such as knowledge level, cognitive ability and preferences. We respectively give the representation of them based on set and tuple. And give the acquisition of characteristic value for prior information and dynamic information. After that, propose a new Adaptive Learning System based on ALM as a case to show the application of this model.
