Abstract

We present the architecture of an Intelligent Interactive Tutoring System (IITS) that is web- based, and can be adapted to courses in engineering, sciences, and mathematics. This research seeks an architecture that can be used by an instructor to make an online learning system for a course the instructor wants to teach in classroom or online, rather than developing an in-depth tutoring system for any specific course. The Intelligent Interactive Tutoring System Shell integrates mathematical tools and an expert-system-type logical analysis/synthesis tool in a web- based environment. The IITS consists of several components including an instructor interface, a student interface, a student model, a student log, a reasoning system, and a mathematical tool interface module, and guides the student through a monitored problem solving session.

1. Introduction Students need academic support outside the classroom, which may be provided by a professor after the regular class hours, or by a tutor, between certain fixed hours of the day. However, there are many students who are hard pressed between work and study, shuttling between the workplace to earn a livelihood, and the college in preparation for a better livelihood. As such, it is not possible for these students to get appropriate academic help during regular office hours, nor is it possible for them to see a tutor at an odd hour when they return home from work. A possible approach to providing academic support to these students is the use of an intelligent tutor that mimics the functions of a human tutor.

Over the last few years, various on-line learning systems and tutoring systems have been developed across the globe. This includes commercial knowledge management systems, such as, Blackboard [1], and WebCT [2], as well as the distance education systems developed at various academic institutions [3-14]. A majority of e-Learning systems concentrate mainly on delivery of course contents over the Internet with little or no room for interactivity. Interactivity
