DESIGNING LEARNING SERVICES FOR OPEN LEARNING SYSTEMS UTILIZING IMS LEARNING DESIGN

The need for e-learning systems that support a diverse set of pedagogical requirements has been identified as an important issue in web-based education. Until now, significant R&D effort has been devoted aiming towards web-based educational systems tailored to specific pedagogical approaches. The most advanced of them are based on the ADL Sharable Content Object Reference Model in order to enable sharing and reusability of the learning content. However, sharing of learning activities among different web-based educational systems still remains an open issue. In this paper we first examine the limitations of the current state-of-the art authoring tools and investigate the use of the Learning Design framework as a mean to address those limitations. Then, we propose a high-level architecture of a learning activities generator and the supporting SCORM compatible authoring system that utilizes the Learning Design principles to provide the means for designing web-based pedagogical scenarios. Finally, we introduce the ASK-LDT, an authoring system developed based on the proposed architecture.
