RESUMO

There is an increasing demand for hypermedia applications based on the WWW (World Wide Web), known as Web Information Systems (WIS). These applications present specific requirements in addition to those of traditional software systems, thus fostering the need for investigating suitable models to support their development. In particular, systems for Distance Education based on the Web present very specific characteristics and requirements. Current models for hyperdocument modeling and specification are not completely suitable for representing domain specific characteristics such as the need of tracking student progress and evaluating their learning process through diagnostic and formative assessments. This scenario motivated the proposal of a model to support WISs targeted at distance education, called MDE (Model for Distance Education). MDE extends the HMBS (Hyperdocument Model Based on Statecharts) hyperdocument model to describe hypertext content in the educational domain. It adopts as its underlying model a variant of the Statecharts formal specification technique, whose organizational structure and operational semantics allows defining the organizational structure and navigational semantics of complex hyperdocuments. MDE also incorporates the technique of conceptual mapping, that adds educational meaning to hierarchical graphs. MDE’s major strengths are thus the ability to capture relevant information about user behavior when studying on-line educational material and make such information available to the teacher / instructor in order to support formative assessment of students. As a proof of concept, the prototype of an environment for authoring and offering distance courses based on MDE has been developed, called ATEnA (Adaptive Training Environment with Support for Assessment). The results of practical and conceptual evaluations of the model and system developed are also presented in this thesis.
