Authoring tool generator for intelligent tutoring systems

The intelligent tutoring systems (ITSs) must deal both with strategy and knowledge in order to help students in the teaching/learning process. The knowledge is generally passed on to the students via teaching/learning activities, which may be generated by an authoring tool instead of being embedded in the tutor project. This way, the tutoring system can be both simpler and more flexible, providing the expert teacher with more freedom to generate new activities with the assistance of computer science professionals. Considering the diverse knowledge domains focused in ITSs, the availability of an authoring tool generator (ATG) to cope with all these different areas looks useful. An authoring tool generated by the ATG works as the link between the teacher and the ITS. Therefore, it must contain an easy to use and clear interface for the teacher to define the activities and at the same time must have a low level structure that allows a straightforward interpretation process done by a computer program.
