Planning Agents in a Multi-agents Intelligent Tutoring System

Abstract. Most recent architectures of intelligent tutoring system (ITS) focussed on the tutor or the curriculum components, but with little attention being paid to planning. Therefore, some works identified two main planning process in ITS: content planning and delivery planning. In this paper, we propose a new ITS architecture that involves sophisticated planning agent at four different levels of the ITS processing. The first planning level (course planning) and the second one (Lesson planning) are derived from the traditional content planning. The third and fourth planning levels come from a decomposition of the tutor module into two different components, one specialized in the tutorial actions planning and the other tailored for the generation of multimedia presentations. After a brief presentation of the new architecture, the paper mainly focussed on the first level planning using SIMPLAN. This planning oriented achitecture takes advantages of previous ITS architecture and provides a uniform view of ITS components that can facilitate collaboration between them
