Abstract—This paper presents an agent based Intelligent Tutoring System (ITS). The agent plays the role of an advisor for an e-learner to facilitate the learner to achieve his learning objective. It provides advices to assist an e-learner while solving problems that are normally provided by human experts. A Bayesian network is employed to construct the possible solution states of a problem with the statistics of mistakes; those can be committed by a learner in their problem solving process. The agent will collect statistical data from Bayesian network on learner’s mistakes and the way in which one learner may commit a mistake. On the basis of the statistical data on the learner’s behaviour, especially with respect to his tendency to commit an error, the agent anticipates the point of difficulty during a problem solving session and accordingly guides the learners to solve the given problem free of errors. The Bayesian network is trained with training data, prior information (e.g., expert knowledge, casual relationships, and estimated graph topology or network structure) and the parameters of the joint probability distribution.
