Architecture Trends of Adaptive Educational Hypermedia Systems: The Case of the MATHEMA

The aim of this article is to present the general architecture trends of Web-based Adaptive Educational Hypermedia Systems (AEHSs) and to give a complete description of architecture of the AEHS MATHEMA. In the beginning, a related work on the architecture trends of Web-based AEHSs is presented. Then, a description of the aspects of the MATHEMA is done regarding both its pedagogical and technological part. Next, one-on-one unit is presented separately and their functions are generally described with respect to the adaptive Web technologies used. Research has shown that students of high schools increase their performance by studying through the AEHS MATHEMA. Also, the formative evaluation of AEHS MATHEMA by students of the Department of Informatics and Telecommunications of the University of Athens, Greece, has shown, with the exception of other things, that all its functions are useful and easy to use.
