This review examined findings from 66 studies of intelligent tutoring systems: 45 system evaluations and 21 component evaluations. The system evaluations compared learning gains from intelligent tutoring systems to learning gains from conventional classroom instruction. The component evaluations assessed the effectiveness of specific features of intelligent tutoring systems. A typical component evaluation compared learning from two different versions of an intelligent tutoring system, one with and one without a certain feature.
