Intelligent tutoring systems have revolutionized online education by providing individualized instruction for each student. Constraint-based tutors model instructional domains at an abstract level, a novel approach that simplifies development of these systems. Over the last decade, the University of Canterbury's Intelligent Computer Tutoring Group has developed effective constraint-based tutors for various instructional domains; some of these tutors have been successfully commercialized. Constraint-based tutoring is a mature, successful approach to providing adaptive learning environments. ICTG-developed authoring tools aim to make this technology widely available to teachers and students. This article is part of a special issue on intelligent educational systems.
