Describes a microcomputer-based system for diagnosing children's multiplication errors which incorporates the knowledge base of all known systematic multiplication errors, and utilizes a modular approach to cope with the program's complexity. Each module's function, how the programs interact, and the design of pupil-machine interaction are…

Describes a knowledge-based tutoring system which provides pupil interaction with the microcomputer to diagnose pupils' errors in subtraction operations. Current subtraction methods; nature and origin of subtraction errors; and the structure, achievements, and future developments of the computer system are included. Thirteen references and a…

Traditional diagnostic intelligent tutoring systems (ITS) are usually intended to be used as standalones whereas nondiagnostic tutors are designed for collaborative learning among students and between teachers and students. This article describes diagnostic and nondiagnostic ITSs, proposes a framework for comparing features of diagnostic and…

Research on intelligent tutoring systems is discussed from the point of view of providing moment-by-moment adaptation of content and form of instruction to the changing cognitive needs of individual learners. Implications of this goal for cognitive diagnosis, subject matter analysis, teaching tactics, and teaching strategies are analyzed. (Author)

Presents a model of instructional design which links cognitive learning theory and instructional prescriptions. Topics discussed include knowledge types and knowledge acquisition; memory system components; learning time; learning objectives, including skills, cognitive strategies, and creative processes; instructional methods that relate to…
