Supporting Intelligent Tutoring in CALL by Modeling the User’s Grammar

Lisa N. Michaud and Kathleen F. McCoy, University of Delaware, USA

The model will be used both to select accurate interpretations of user-written sentences and to focus system-delivered instruction on topics at the frontier of the learner’s competence.
