Overview of MOT Knowledge representation system : Basic Modeling Editor LexiconGrammarSemantics Pragmatics MOT Editor
Modelling using Object Types §Knowledge types are useful for Learning Environment Electronic Performance Support Systems §Integration of different viewpoints in the same model: domain, functional, strategic §Semantic transparency and ease of use §A small number of knowledge types and links are sufficient to represent complex models: § Conceptual: class/sub-class, part-of hierarchy § Procedural: sequential, parallel, iterative § Prescriptive: constraints, theories, decision, control § Methods and Processes: analytic, adaptative, synthetic

III- The Modeling Process Building a MOT knowledge model Initial development Validating sub-models Structuring the model
The Modeling Process
Generic Scenarios §A process model of learning activities based on generic tasks such as classification, diagnosis, planning or modeling §A collaboration model involving the different actors in the process: learners, tutors, content experts, managers §A media delivery model associating to activities information resources and production tools
Step-1 - Start with the production process
Step-2 - Add the collaboration/role component
Step-3 - Add the media and tools component
