Web-Based Learning, Learning Object, Semantics, Reusability


In the design of activities for Web-Based Education Systems, the concept of Didactic Object or Learning Object, has appeared as the axis of a new paradigm concerned with the reusability of contents and activities, due to its organization from a conceptual point of view, the use of metadata in known formats and the setting of new standards. In this article, the concept of reusability is analyzed within the context of the systems mentioned. In addition, Sowa-Style Conceptual Maps as well as Hypermedia Conceptual Maps are proposed as schemes capable of representing knowledge, since they allow for a clear visualization and tend to enable known automated functionalities accurately. The above mentioned resources tend to complete the information in metadata with regard to the semantic aspect.
