Generating task-specific next-step hints using domain-independent structures

Abstract

With the ASTUS framework, our aim is to facilitate the creation of tutors showing sophisticated pedagogical behaviors while keeping the authoring effort in line with that required by other well-known frameworks. ASTUS is thus based on knowledge structures that can be manipulated by the tutor's modules in order to, for example, generate task-specific next-step hints. An experiment suggests that the generated hints can be as effective and as well appreciated as those authored by a teacher. © 2011 Springer-Verlag Berlin Heidelberg.
