The Web offers advantages for learning technologies, but the interactivity necessary for the learner requires technical features that are currently hardly supported. The authors briefly describe how a traditional multimedia course, usually marketed as offline CD-ROMs, has been reverse engineered to a server-based, multi-client Web application in order to have an identical behaviour at the learner's site. The new course consists of XML/XSL documents programmed by server-driven Java functionalities managing the conversations with the remote learners. Abstraction and generalisation to other courses and/or interactive Web applications or services, become feasible, easy and reusable because all middleware technologies are open source. |
