In this paper we investigate the role of a new algebraic fuzzy structure as dynamic model to represent user's states during navigation in a multimedia tutoring system. The structure can be profitably utilized to monitor the evolution of mental states in order to suit the resources and the didactic strategies to the user's needs. The problem of building a user model is favourably affected by our approach: in fact the huge quantities of data present in overlay and bug catalogue models are no longer required. The fuzzy structure allows to monitor the cognitive variables that are necessary to design a user model that can operate in a way independent from the particular topic to be taught.
