A Cognitive Model for Building "Cognitive Tutors"

To build learning environments that can provide tailored assistance to learners during learning activities, a popular solution is to model the cognitive processes of learners with a cognitive model. It allows a tutoring system to closely follow the reasoning of learners to then generate tailored assistance. This is the idea originally proposed in the Cognitive Tutors by Anderson et al. (1995). However, their cognitive model can be improved in several ways.

For this reason, we have decided to build an alternative cognitive model. The model is directly inspired by the work on Cognitive Tutors. But it provides several originalities such as:

This work has resulted in a knowledge representation framework [1,2,3] comprising mainly:

The current version of the framework (2006-..), described in [1,2] has been applied in the following projects:

Fig 2. The Latest Version of the Authoring Tool


Fig 3. The Redbool Tutoring System

Earlier versions (2003-2006) of the knowledge structures and interpreter have been designed with André Mayers and have been described in my M.Sc. Dissertation (P. Fournier-Viger, 2005). They have been used in several projects including:
