Allowing the student to have some control over the diagnosis inspecting and changing the model the system has made of him is a feasible approach in student modelling which tracks the dynamics of student behaviour and provides for reflective learning. We present an approach for maintaining the student model in interactive diagnosis where a computer and a student discuss about the student's knowledge. A belief modal operator is adapted to model the knowledge of the learner and to help in maintaining the interaction between the computer system and the learner. A mechanism for finding agreements and conflicts between system and learner’s views is described.
