Abstract
This paper describes an intelligent CAI system, called CALAT, which provides an individual adaptation capability on the World Wide Web (WWW). CALAT consists of an intelligent tutoring system (ITS) on a WWW server. A newly developed user identification mechanism makes the system capable of adapting to individuals over the stateless protocol of the WWW. A viewer control mechanism using control script has also been developed in order to improve response speed and to implement viewer control capability from the server. An evaluation experiment shows that the individual adaptation capability works well and that the response speed is sufficient for practical use. CALAT is now in operation on the Internet. © 1997 Scripta Technica, Inc. Syst Comp Jpn, 28(9): 17–25, 1997
