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.
