Authoring Roles – regular LM
• Author performs all (or at least most of)
  the tasks required in creation of the
  learning material




                           Invited Tutorial, Madrid, Spain April 2008
   Authoring Roles – intelligent LM
• Author could perform all (or at least most of) the
  tasks required in creation of the learning
  material
• Ideally, authoring roles would be applicable,
  depending on the specialization of the author
  – Domain
  – Adaptation mechanism
  – Meta-data
  – etc.

Authoring & standardization

• Formalization attempts:
  – standardising the whole procedure
• Research on a systematic base
  – clear explicit models for adaptive authoring




                             Invited Tutorial, Madrid, Spain April 2008
Conclusion authoring
• The tasks are divided
• The domain is restructured and divided
• A lot of new components emerge

• So we need a framework to describe
  this new structure
