Didactic Models as Design Representations

摘要

The contribution focuses on the role of didactic knowledge when designing interactive e-learning environments. Several representational approaches for the preparation of domain content and learning support have been developed. However, for the context-sensitive design of interactive artifacts not only the representation of particular aspects of learning is essential, but rather the propagation of didactic knowledge to functional services and interaction facilities. Such an endeavor requires the explicit representation of relationships between structure and behavior elements. Model-driven design supports the distinctive representation of multiple perspectives while allowing the mutually tuned refinement of design elements. In this paper a model-based approach for self-organized e-learning is presented. It supports the design of learner-centered knowledge acquisition by specifying user roles and learning tasks. We discuss the required enrichments of traditional model-based design approaches, due to the consistent tuning of high-level design elements, and the coherent propagation of task and user information to interaction services.
