Using Argumentation to Persuade Students in an Educational Recommender System

This paper explores the use of argumentation-based recommendation techniques as persuasive technologies. Concretely, in this work we evaluate how arguments can be used as explanations to influence the behaviour of users towards the use of certain items. The proposed system has been implemented as an educational recommender system for the Federation of Learning Objects Repositories of Colombia that recommends learning objects for students taking into account students profile, preferences, and learning needs. Moreover, the persuasion capacity of the proposed system has been tested over a set of real students.
