Diversification of the resources, qualityThe diversification of the resources has an also qualitative dimension in any event. Report which implies to be above all able to identify the significant resources, and to establish a taxonomy of the various types of resources. Today, we have a new generation of supports which have specificity clean: multicanality, multireferentiality, hypertextuelle navigation. New constructions of the knowledge imply the implementation of new cognitive strategies, and especially to redefine the active role of the learn-user. These specificities must be examined and put in connection with objectives of training in order not to yield to the lying postulate according to which each new tool would be higher than the antecedents. Another risk consists in being unaware of the contributions of the NTIC and transferring on these original supports from the accessible contents on paper, (for which paper proves in fact more relevant). The complexity of these new supports in addition calls in question the concept of mass culture, validates for the other “traditional” media.
