Intelligent Tutoring Systems
One of the most difficult things with ITSes is actually getting the knowledge in the correct format so that the ITS can work. What may be a useful or interesting technique is using something akin to the Socratic method on the domain expert. So that the domain expert is asked definitions of things and elaborations so that the knowledge tree can be created.
One difficulty would be figuring out how to do this for more procedurally material and the relationships between topics, not just hierarchal categories or information about what aggregates are made up.
Perhaps creating a having the domain expert create a few scenarios before hand to highlight concepts and operations would also be useful.
Now, the other question is can the pedagagical structure for an ITS be automatically generated from this knowledge tree? Is that task easier to do in any way?
