Abstract
This paper deals with the exploration of proper information technologies and services to support a number of activities in web-based distance educational initiatives, and with the description of related experiments performed in some university courses of a computer engineering curriculum. These activities, usually carried out by course authors, tutors and learners, include searching and locating educational resources over the Internet, sharing and reusing them, and online delivery to the learner, possibly in a way adaptive with respect to learner's skill and preferences. Specifically, in this paper we present the work done within the project GESTALT of the European Union 4th Framework Programme, and continuing within the project EASEL of the 5th Framework Programme, to develop standard-based metadata models, which facilitate the development of efficient resource discovery services and management of learning resources. We then present the results of trials performed at the University of Naples, where the metadata models have been used and tested with the GESTALT online learning system.
