This research addresses the issue of automatically generating instructional hypermedia documents (in the form of web sites). Our hypothesis is that, for certain types of hypermedia, an automated approach can produce satisfactory hypermedia applications more efficiently than humans are able to create them. We propose a method (APHID) that guides a hypermedia creator through the design process and partially automates the creation of hypermedia applications. Our method uses concept maps and instructional design patterns, as well as the more common domain and presentation models, to support partial automation for creating instructional hypermedia. Most hypermedia application developers follow basic graphical design principles, but few commonly accepted principles exist for the structuring of hypermedia applications. The design of instructional hypermedia imposes the additional requirement that the designer be expert both in hypermedia design and in instructional design. APHID supports designers through the use of patterns to describe and clarify design concepts for both instructional design and interface design. This thesis describes the design and development of the APHID approach and a prototype software tool that supports the development of instructional hypermedia using the APHID approach. The thesis also presents a study in which web sites created with APHID are compared (by an independent evaluator) to web sites created by instructional technologists. The study shows that good instructional web sites can be generated semi-automatically with less expenditure of time on the part of the instructional designer.
