The articles here combine breadth of perspectives with a focus on the field's two major areas of work: learning environments and tutoring systems. The section on learning environments addresses issues of cognitive style, metatheoretic objectives, domain analysis, and a variety of implemented prototype systems: programming by example, Object-orientated Logo and the educational use of constraint based language. The domains of application range from single-word learning to algebra and architectural design. The section on intelligent tutoring systems (ITS) presents a spectrum of work grown out of the classic knowledge engineering paradigm, discussing principles and emerging methodologies for ITS construction: authoring shells, user modelling, and the role of machine learning. The applications reported range from elementary number knowledge to electronic circuits and complex industrial processes.

The convergence of interests between advocates of intelligent tutoring systems and those of more exploratory learning environments is being realized in a melding of research programs and implemented systems, exhibited in fact by the chapters collected for this volume.
