As multimedia training environments become increasingly popular, many have placed multimedia systems diametrically opposite to intelligent tutoring systems (ITSs) in a schema of educational applications of computers. Some argue, however, that multimedia systems lack the goaloriented teaching approach of an ITS. Multimedia could, however, be integrated into the architecture of an ITS, such that information is easy to create and to retrieve as networks of interconnected multimedia documents, together with the different means of delivering information to the student. This paper illustrates, through the discussion pertaining to the implementation of ARISTOTLE, a tutoring system for zoology, how multimedia can be incorporated into an ITS.
