Outlines two traditions in the field of computer simulation, one focusing upon the character of the software within the computer, the other focusing upon the exercise outside the computer which the software is supporting. Topics discussed include mathematical modeling, gaming, information retrieval, decision monitoring, and applications in…

Progress is reported on four research tasks. An experiment tested the effectiveness of a computer-based phonology instructional system for second-language learning. In research on models of human-computer interactions, experiments were performed demonstrating that the provision of certain incentives to the users of a time-sharing system can have…

A rationale for the use of gaming and simulation for instructional purposes is developed in the introduction to this paper. The major portion of the text is comprised of several models of computer programs for economics instruction. (SHM)
