Pedagogical hypermédias systems

As practice and profession, education has always been a discipline in the heart of the development of systems and hypermedia applications. With through work which was completed, we note that the great majority of the studies was interested in the aspects of access to information and the challenges posed by exploration. Thus, most of work explored, for example, the cognitive overload or confusion during navigation. However, and without leaving side these problems common, we wish to examine here other also essential aspects concerning a constructive use of the hypertextes. This study is targeted on the hypermédias teaching, included/understood as a subcategory of the informative named hypertextes which are defined in opposition to hypertextes literary, artistic or walking.
