The results show significant differences indicating that students using the cognitive system (MAP) spent more time attending resources on the user interface than students in the adaptive hypermedia system (TIX).
We implemented the GEK model in two educational systems: a web-based adaptive hypermedia system (TIX) that controls link activation and a cognitive tutoring system with dialog interaction (MAP).
It can be used indistinctly by different systems like adaptive hypermedia or cognitive systems.
Part of the Carver, Howard et al (1999) work was to develop an adaptive hypermedia interface that provided dynamic tailoring of the presentation of course material based on the individual student's learning style.
According to Brusilovsky (2001), while adaptive hypermedia researchers have begun exploring the use of individual traits for adaptation in several areas, it cannot be described as a success story at present.
