Abstract
In previous hypermedia research studies, most of the subjects were students in post secondary education. That is, we haven't paid attention to the possibility of hypermedia in elementary and secondary education stages. It means that there is no sufficient basis to confirm the potential of hypermedia in those stages. The problem seems to lie in the fact that we have neglected the examination of a theoretical basis to hypermedia. The author examined the theoretical basis, which was deeply concerned with the Three Stages of Knowledge Acquisition Model suggested by D. H. Jonassen (1991; 1992), reviewed the structuredness of problems in artificial intelligence, W. R. Reitman (1964; 1965) and H. A. Simon (1973), and suggested a theoretical model for supporting the possibility of hypermedia in elementary and secondary education stages.
