A framework for constructing adaptive Web-based educational systems

Adaptive educational systems are often built from scratch with no general methodology that would enable the system to be easily reused in another domain (G. Gauthier et al., 2000) We propose a general methodology to structure the taught domain into so-called "knowledge units" that can be treated in a unified way. Individualization of the learning process for a particular student consists of two layers: a cognitive and a presentation layer. We briefly describe our framework for the construction of Web based educational systems. A course in elementary mathematical functions is presented as an example of our approach.
