Fifteen years of constraint-based tutors: what we have achieved and where we are going

Abstract: Fifteen years ago, research started on SQL-Tutor, the first constraintbased tutor. The initial efforts were focused on evaluating Constraint-Based Modeling (CBM), its effectiveness and applicability to various instructional domains. Since then, we extended CBM in a number of ways, and developed many constraint-based tutors. Our tutors teach both well-and ill-defined domains and tasks, and deal with domain-and meta-level skills. We have supported mainly individual learning, but also the acquisition of collabora… Show more

“…Although we illustrated the proposed methodology with a case study in the area of exploratory learning system in which the conceptual model referred to strategies, the methodology is appropriate for other 690 adaptive learning system, where the conceptual model can refer to other common aspects used in current research, such as concepts of the learning domain [18], constraints [65] or competencies/skills [16,31].…”

“…Table 1 provides some examples of how knowledge is characterized by the system. This form of knowledge representation was adapted from research on skill modeling with intelligent tutoring systems [9][10][11]. The system is currently under development with the assistance of domain experts in order to be capable of updating these representations as students are interacting with the learning environment.…”
