This survey of intelligent tutoring systems describes the components of these systems, different teaching scenarios, and the relation of these systems to a theory of instruction. It argues that the underlying pedagogical approach is to make latent knowledge manifest by using different forms of quantitative modeling: (1) simulating physical…

Discusses the performance of a long-term intelligent training system for the U.S. Air Force, Sherlock I and II. The Sherlock systems have been effective, but their acceptance rate has not been high. An attempt is made to understand this paradox, and approaches for improving the systems' effectiveness are proposed. (Contains 19 references.) (JLB)

Discussion of the use of computer simulation in the social sciences highlights types of simulation strategies and their combinations in comprehensive simulations. The strengths and weaknesses of simulations as instructional and research tools are examined, examples are given, and design issues arising in each type are explored. (29 references)…
