How to orientate arcs in a Bayesian network based student model

Abstract : Bayesian networks have been successfully used for student modeling in many systems. In this paper, we address the problem of Bayesian network structure construction and more particularly that of arc orientation. We think that, in the case of cognitive task modeling, the traditional causal interpretation of arc orientation is not adequate. Instead, we use the information flow to provide a systematic a priori analysis of the conditional dependencies between variables. Finally, we explain why we think that different Bayesian networks should be taken into account and how this could be done.
