After having introduced the “Full-Hypermedia Systems Design Model” (FHSDM) in previous works (García 2001), it is about time to present in more detail one of the cornerstones of the model: the Exposition Dimension.



Briefly, the FHSDM considers the learning process and the design one as composed by two clearly separated dimensions: the Structural Dimension and the Exposition Dimension. The former is related to the hypertextual characteristics of the system, and its goal is to convey Structural Knowledge. The latter deals with the presentation of concepts, and allows for the exposition of Declarative Knowledge.



In this paper we intend to have the pedagogical grounds for the Exposition Dimension more fully explained. But our main goal is to present the technical research in which we have been looking for the most effective way of implementing Docuschemas, the multimedia presentation conceptual device we have developed in order to maximise cognitive efficacy.
