A multilevel learning management system

Abstract

Many authoring systems have been realized so far in order to allow users to build advanced presentation of documents. These systems represent the result of a requirement analysis performed in specific application domains and their functionality is meaningful for the domain experts. Consequently, in many cases there exists a barrier between system functionality and users, who have a limited knowledge of the domain: in order to use the application, the content expert end-user has to interact with the application expert. Such a barrier limits the effectiveness and the efficiency of the authoring system, because the development of a multimedia presentation forces the user to acquire experience far from his/her background. In this paper we introduce a new approach to educational authoring, based on a multilevel development methodology. It allows and supports teachers to create their own multimedia learning environment. The proposed approach has been experimented on an initial prototype which allows users to manage multimedia authoring of units of study.
