In this study, students studied two different domains in the same Intelligent Tutoring System, Andes. Analysis of 435 log files from 22 subjects indicated that there are two types of interactive behaviours in Andes: domainindependent and domain-specific. We believe the existence of the domain-specific behaviours is one possible reason that similar meta-cognitive behaviors has not been found across domains in a single ITS curriculum [1][2]. This paper describes the study and the potential applications of these findings.
