| Abstract: The personalized exercise path recommendation technology can take into account the individual characteristics of learners and customize the exercise path for them. In this paper, the research work on personalized exercise path recommendation is systematically reviewed. First of all, from the perspective of recommendation methods, the global optimal exercise path recommendation and local iterative exercise path recommendation methods are introduced, and the advantages and problems of the two types of recommendation methods are summarized. Then, from the perspective of the core algorithms that are widely used in the current personalized exercise path recommendation work, five methods are introduced, which are based on collaborative filtering, cognitive diagnosis, knowledge tracking, in-depth learning and reinforcement learning. Finally, current research difficulties in this field are discussed, and the future research directions are prospected. |
