Interactive Multimedia Intelligent Tutoring System (IMITS) : A Progress Report

Brian P. Butz, Michael Duarte Intelligent Systems Application Laboratory College of Engineering Temple University Philadelphia, PA 19122

Abstract The Interactive Multimedia Intelligent Tutoring System (IMITS) is an intelligent tutoring system that is focussed on the instruction of undergraduate electrical engineering students. The material covered is that typically presented in courses on introductory circuits. At present, it consists of three modules: DC, AC and Transient Analysis. IMITS is intended as a course supplement. While there is a substantial amount of multimedia material and interactions, the software package is intended as a tutor, providing extra help for a student taking a face-to- face, on-line, or self-directed course. As the student progresses through the material, the expert system that is embedded in the software will watch and analyze the student’s activities. By doing this, it is able to determine the student’s strengths and weaknesses and determine what material should be presented in what order. The IMITS software environment has been under development for three years. It has recently been sent to several colleges and universities throughout the country for testing and evaluation. This paper discusses the present state of IMITS.

Introduction A continual challenge in teaching is meeting the students' academic needs and ensuring that they are active participants in their own education. Over the last decade, studies 1-5 have reinforced the notion that students best learn if they are active participants in their education. Interactive multimedia software is playing a key and unique role in the educational process. It has been used as a stand-alone educational module that is intended to enable an interested individual to learn about a particular topic or subject 6 , as a supplement to classroom presentations 7-9 , and to laboratories10, 11, and as a dynamic textbook 12. Recently, interactive multimedia have been integrated with expert system technology producing intelligent tutoring systems for engineering students 13-16 . These intelligent tutoring systems "learn" about the individual student and can tailor the material to meet the needs and the learning styles appropriate to the individual student.

The goal of the Interactive Multimedia Intelligent Tutoring System (IMITS) is to develop an intelligent tutor for an introductory sequence in electrical circuits and systems. The framework developed for this system is to be transferable to and used by any discipline, not only engineering. The project has as its major goals to: 1) Develop and integrate the components necessary to form an interactive multimedia intelligent tutoring system.
