The didactical object model: managing didactical expertise

The didactical object model extends the approaches of existing educational modeling languages introducing specifications for contents and experiences. In this paper, it is shown how the didactical object model can be used for sharing didactical expertise. Educational modeling languages change the design paradigm from content orientation towards process-activity orientation. Especially in the community of teachers and didactical designers this development has gained attention. However, re-using learning scenarios requires to apply knowledge management concepts to this issue. To adequately reuse learning scenarios, information on the context and about experiences must become available. The DIN didactical object model, developed in the German standards body (Deutsches Institut fur Normung, DIN e.V.), provides specifications for this. The presented modeling language enhance the use of educational modeling language towards knowledge-based exchange of learning scenarios and experience sharing.
