Use of learner agents as student modeling system and learning companion

Instructional systems are computer programs that provide educational support to individual learners. One such system is the intelligent tutoring systems (ITSs). ITSs center on individualized learning and do not consider the situation where learners can learn beyond the teacher-learner relationship. Several learning companion systems (LCS) were implemented to create social learning environments. However these systems are merely extensions of tutor agents and act as "learners". In this paper, we introduce the use of learner agents both as student modeling systems and as peers.
