Instructional Models and Scenarios for an Open Learning Repository Instructional Design and Metadata

In this paper we present the evolution of a metadata-based course portal, the Open Learning Repository (OLR for short). Different instructional models and principles are integrated in order to meet different learning and teaching strategies. To achieve this, different metadata models (domain model, instructional model, cooperative and structural model) are designed and mapped. In a scenario-basedevaluation of a former version designers, teachers and developers realized that the use which is focussed by implementation can differ from actual use by learners. Therefore, in OLR we do not only implement different instructional principles and theories but also help-files which address the learners reflection of their own learning strategies. Different learning strategies as well as organizational framework serve as relevant context which is addressed by scenarios written by all stakeholders. Scenarios furthermore serve as medium for communication between instructional designers, computer scientists and teaching staff.
