On the other hand, the content of each page itself can be adapted to the user's knowledge. Qualified users need to receive more detailed and deep information, while novices need more additional explanations. The system provides an ability of such adaptation for the user. Our approach to building adaptive HM systems is based on the ideas from the domains of intelligent tutoring systems and adaptive interfaces. The system is designed as a set of modules integrated by interlinked domain and student models.
All modules can use and update the student model.
The central part of the hypermedia network represented on the Web is designed as a visualised DM network. The tutoring component plans the optimal sequence of multi-concept operations and uses it to hint, help or even control the user. The system's knowledge base is stored as a database on the SQL Server. The database is accessed from the IIS using ODBC drivers. Therefore, each DM node has a reference to it's homepage.
