This paper describes some of the strategies and knowledge tutors use in teaching about the causes of rainfall. Underlying a tutors ability to diagnose and correct students misconceptions are a set of models of the rainfall process. These models allow students to understand a system from different points of view and to derive the consequences of changing different critical variables in the model. Students misconceptions often derive from incorrect models of the system and diagnosing these misconceptions requires expert knowledge of what distortions can occur in students models. Author
