Model-based learning environments

Abstract

The development of intelligent tutoring systems (ITS) was in the focus of computer-based learning during the last twenty years of the last century. But most ITS did not find the way from the laboratory to use in standard learning settings. During the last ten years, adaptive learning environments emerged, a promising alternative to ITS. Both, ITS and adaptive learning environments use some more or less sophisticated type of user modeling. At hand of the web-based learning environment ELM-ART that combines both an ITS for problem solving support as well as adaptive features for navigating through the learning materials it is shown how user modeling can be used to facilitate learning. Finally, NetCoach, a Web-server for presenting and authoring adaptive on-line learning environments will be introduced. © 2008 Springer-Verlag US.
