A Service Providing Awareness of Learning Object Evolutions in a Distributed Environment - 2008 ECTEL

In some previous works we suggested a mechanism that offers the opportunity to import, within courseware deployed within Learning Management System, some learning object stored into heterogeneous repositories. Works presented here allow teachers and curriculum managers to be aware of all divergences between the imported learning objects and their evolutions, releases and dependencies. It avoids collaboration between production stakeholders and teachers to spiral out of control by providing teachers with visualization techniques such as State Treemap and 3D relationships representation together with notification systems. The framework has been implemented in an open and LOM-based architecture that includes Moodle and the Ariadne Knowledge Pool System, thus validating our approach.
