Bayesian belief networks have been widely used in student and user modelling. Their construction is the main difficulty for their use in student modelling. The choices made about their structures (especially the arcs orientation) have consequences in terms of information circulation. The analysis we present here is that the network structure depends on the expertise level of the student. Consequently, the evolution of the network should not only be numerical (update of the probabilities) but also structural. Hence, we propose a model constituted of different networks in order to take into account these evolutions.
