Control for Intelligent Tutoring Systems: A Comparison of Blackboard Architectures and Discourse Management Networks
Abstract
An intelligent tutoring system must have some control mechanism for deciding what instructional action to perform next. Traditional CAI systems have inflexible control mechanisms that procedurally encode tutorial strategies and prevent them from being readily extended to handle new domains or tutorial strategies. Two alternative architectures proposed recently to address these problems are discourse management networks and blackboards. This paper compares these two architectures and argues that an intelligent tutoring system controlled by a blackboard architecture can deliver significantly more effective and flexible instruction than one controlled by a discourse management network. Keywords: Intelligent tutoring systems, Instructional planning, Dynamic network, Training dynamic planning, Blackboard architecture, Discourse management network, Devices.
