An Intelligent Interactive Tutoring System for an Electric Circuits Course
This paper summarizes the development of an intelligent tutoring system for a sophomore level course sequence on electric circuits. The tutoring system is based on the Intelligent Interactive Tutoring System Shell, developed earlier. It has several features: a) it is web based which makes it accessible to students at any time, b) it is interactive much like the way a student interacts with a human tutor, c) it is intelligent in the sense that it mimics the teaching style of a human tutor, and d) it is adaptable by any instructor. The course material is organized as a collection of logical interrelated topics with examples, and exercise problems. The tutoring system maintains a database for every interaction that the student makes with the system. As the student progresses through a course, the system records every move that the student makes, such as, the number of attempts that the student makes in solving a particular problem, whether the student is able to solve a problem, etc., and suggests prerequisites as the student stumbles on a problem. This tutoring system is flexible enough to allow any instructor to configure it for his or her own course.
1. Introduction With advances in computer technology, it is possible to use multimedia technologies, such as, video, audio, and interactive simulations to promote the student’s understanding of the particular concept. Such computer based multimedia technologies could be broadly classified into two categories: e-learning systems, and e-tutoring systems.
e-Learning systems are particularly suitable to convey the course material through multimedia tools including audio/video, and interactive simulations. Various audio, video, and text files are easily transmitted to the students through Blackboard1 and webCT2 environment as well as non- commercial e-Learning systems3, 4, 5 that have been developed at various academic institutions. Web based interactive laboratory experiments have also been developed for electrical circuits5,6, electronics7,8, fluid mechanics, and control systems courses9, 10, 11, 12, and various other courses. Some of these systems also allow certain level of interactivity through the use of whiteboard, chat, email, and other interfaces, however, lack an interactive environment for monitored problem solving, and feedback. On the other hand, an e-tutoring system is ideally an electronic counterpart of a human tutor. The e-tutoring system must be capable of guiding the student when he or she stumbles on a problem, suggest background or prerequisite material, understand the student’s readiness for the course, and keep track of student’s progress through the course.
