An Authoring Language as a Key to Usability in a Problem-Solving ITS Framework

摘要

Step-based ITS have been proven successful in well-defined domains, but their success is mitigated by their cost. Different approaches have been investigated to reduce these efforts; one of them is a framework that eases the development of tutors for a given class of task domains. In this paper, we explain how a domain is modeled with the ASTUS framework and we discuss why an authoring language is a promising technique to improve its usability.
