Abstract
The flexible nature of hypermedia allows it to be tailored to an individual's needs. Despite the many degrees of navigational freedom, however, users of hypermedia often find difficulty locating information, feel disoriented, or even become “lost in hyperspace” within such large seas of data. Research findings suggest that the disorientation problem could be solved if users are able to hold a conceptual overview of the hypermedia structure. Variables such as the different ways of representing information structure cues and cognitive styles may affect learners' cognitive abilities in knowledge structuring and should be taken into account together.
