An intelligent tutoring system for circuit analysis

The Interactive Multimedia Intelligent Tutoring System (IMITS) is designed to assist electrical engineering undergraduate students taking their first circuits courses. The IMITS system places the student in a real-life engineering scenario in which the student is a newly hired engineer within the fictional IMITS Corporation and given "real-life" problems to solve, corresponding to course material. The office has file cabinets, bookshelves, a printer, and a personal computer. The personal computer allows the student to receive televideo messages, receive "e-mail", and send "e-mail" reports to senior engineers. A feature of IMITS is that the student decides which actions to take and may validate analyses and designs using a virtual laboratory incorporated with the software. A brief historical perspective of intelligent tutoring systems is presented, followed by an explanation of their architecture. Next, a detailed discription of the intelligent tutoring system IMITS is given. Then the results of usability and effectiveness evaluations of the software are given
