This project explores the use of multimedia for the specific application of developing instructional hypermedia manuals that explain how machines work. This paper describes a theoretical model for stages in the comprehension of a machine from diagrams and accompanying text. From this model, the article discusses the process of designing hypermedia manuals that explain how machines work. Manuals that were based on this model were evaluated in a set of experiments. The authorsí conclusions focused on the fact that hypermedia did not show any distinct advantages over print media, but diagrams assist in conveying conceptual ideas and should be accompanied by textual explanations.
