In educational technology and learning sciences, there are multiple uses for a predictive model of whether a student will perform a task correctly or not. For example, an intelligent tutoring system may use such a model to estimate whether or not a student has mastered a skill. We analyze the significance of data recency in making such…

The document covers an operational entity-simulation system designed to permit observation and selective control of a military personnel system under a variety of policy alternatives. PERSYM is modularized to facilitate conversion to different military forces and the programing and inclusion of alternative policy logic modules. The system…

This study sought to develop a predictive model for use by educational decision makers in establishing junior colleges, as more needs and costs become known and more precise bases for judgment are needed. Decision-making models were considered suitable for this study. Correspondence with officials produced a valid list of criteria and identified…

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)

The purpose of the research described in the report is twofold. First, it is to analyze the relative benefits and costs of on-line computerized placement systems. The techniques developed for such an analysis which might be useful in evaluating other manpower programs are presented. Second, it is to provide a prototype model which shows how…
