Towards a generic conceptual design meta- model for web-based educational applications

The WWW has turned into a development and run -time environment for large-scale and complex applications among which are the educational applications. There are now justifiable research and development efforts that attempt to formalize the engineering process of such applications in order to achieve better learning effectiveness as well as development efficiency. A lot of work has been done in the field of the instructional designing rather than on hypermedia designing of such applications. Most of the design methods that have been used are general purpose hypermedia design methods which do not allow much in either the conformance of the design models to the latest learning technology standards, or in their seamless translation to standard data formats. This paper presents an attempt for facilitating the conceptual design of web-based educational application by meta-modelling their underlying content and navigational structure. This work is based upon and also extends the OOHDM principles. The Unified Modeling Language (UML) serves the purpose of notation syntax and semantics for this meta-model. The theoretical analysis of the model is accompanied by relevant examples.
