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

We present and discuss the evolution of a metadata-based course portal, the Open Learning Repository. Different instructional models and learning principles are integrated in order to meet different learning and teaching strategies: different metadata models (domain model, instructional model, cooperative and structural model) are designed and mapped. A scenario-based evaluation of a former version of OLR revealed that the use which was intended by designers and teachers can differ from actual use by learners. In the current version we do not only implement different instructional principles and theories but also helpfiles which address the learners reflection of their own learning strategies. In the design process, different learning theories as well as the organizational framework serve as relevant context which is addressed by scenarios written by all stakeholders. Scenarios serve as medium for communication between instructional designers, computer scientists, and teaching staff.
