RECALL: individual language tutoring through intelligent error diagnosis

Abstract

RECALL aims at providing intelligent error feedback to learners' input in a role-play scenario. This is achieved by integrating three intelligent modules into into system: a Diagnosis Module which analyses the learners' input, a Learner Module which reocrds errors made by the learner, and a Tutoring Module which provides exercises and offers feedback. In this paper the functionality of the RECALL system is described and the approach to error classification as well as the actual implementation of this approach is discussed. A pedagogical perspective on the navigational and teaching capabilities of RECALL are considered.
