A simple method of representing reusable strategic knowledge for MT tutoring

Abstract

Several popular model-tracing tutors are available today, but they are usually limited by common general compromises, such as (1) between the complexity and the variety of the domains taught, or (2) between the precision of student modeling and the degree of easiness to model new domains. We present an improved version of the ASTUS formalism, allowing the modeling of more complex knowledge while simultaneously increasing the diversity of pedagogical behavior, with no loss in diversity or time consumption. © 2011 Springer-Verlag Berlin Heidelberg.
