Interaction paradigms with educational hypermedia

This paper discusses two projects aimed at utilising the educational potential of hypermedia whilst avoiding the danger of the user becoming "lost in hyperspace". The first project adopts a connectionist approach to configure dynamically the links made available to the user. The paper outlines the neural network approaches adopted and reports on results to date. The second project concerns the development of educational packages providing a range of navigational aids to the user, and the paper reports on empirical work involving the use of such a package by students in a tutorial context.
