The widespread availability of platforms for producing hyper-systems (i.e. hypertext and hypermedia) shows
great potential for producing computer based learning environments. However, we do not yet have a great deal
of experience in understanding how to make best use of the structural and media possibilities opened up by
such systems. This paper explores the issues by analysing the techniques used by designers within a variety
of different hyper-systems and begins to develop a space of potential design solutions and their likely impact
on learning. We report the general findings of an expert evaluation of recent hyper- systems. The study
produced the following six dimensions: purpose of the hyper-system, domain or content, structure of the nodes
and links, navigation methods, control, and style of presentation. These were used to examine the designs
more closely using a Design Space Analysis framework and notation known as QOC. Performing a
retrospective analysis has provided insights about how these dimensions relate to learning from hyper-systems
and how the dimensions can influence designs for learning material. We expect that our findings can inform
educational hyper-system design.
