The paper reviews the literature on use of computers with retarded students in three chapters dealing respectively with the historical context, current issues, and future directions. The chapter on the historical context reviews research on the efficacy of teaching machines with this population. Research on the effectiveness of computer-assisted…

The premise of this presentation is that clinical experiences are superior to many traditional kinds of field placements. Four types of clinical experiences are described: participant observation in special education classrooms; a team planned cooperative teaching experience; participation in the activities of a college reading clinic; and…

A nominal response model-based computerized adaptive testing procedure (nominal CAT) was implemented using simulated data. Ability estimates from the nominal CAT were compared to those from a CAT based upon the three-parameter logistic model (3PL CAT). Furthermore, estimates from both CAT procedures were compared with the known true abilities used…

Achieving enrollment goals continues to be a major administrative concern in higher education. Enrollment management can be assisted through the use of computerized planning and forecast models. Although commercially available Markov transition type curve fitting models have been developed and used, a microcomputer-based decision planning model…

One means by which subordinate leaders in armor units can practice command, control, and communication (C3 skills) before participating in field exercises is with the use of a computer supported battle simulation. This report describes the functional requirements and hardware configuration for Simulation in Combined Arms Training (SIMCAT), a…

This study examined how four commonly used test equating procedures (linear, equipercentile, Rasch Model, and three-parameter) would respond to situations in which the properties or the two tests being equated were different. Data for two tests plus an external anchor test were generated from a three parameter model in which mean test differences…

Materials and directions for classroom simulation of the formulation and upkeep of a typical French family's budget are presented. The game is intended for intermediate and advanced students of French and adaptable for various class sizes. It is a communicative game, designed to provide an enjoyable atmosphere for true-to-life information exchange…

Sampling distributions for ten tests for comparing population variances in a two group design were generated for several combinations of equal and unequal sample sizes, population means, and group variances when distributional forms differed. The ten procedures included: (1) O'Brien's (OB); (2) O'Brien's with adjusted degrees of freedom; (3)…

This is a critical review of the analytical models developed by the U.S. Army to predict training device effectiveness. The Simulation Systems Technical Area of the U.S. Army Research Institute for the Behavioral and Social Sciences performed the research. Special consideration is given to a family of models known collectively as TRAINVICE. These…

Free-form games are applicable to a range of problem-solving situations. This document discusses gaming as a procedure for organized study of the complex problems entailed in confrontations and crises. The major focus of the booklet is on the various forms of this game type, the kinds of problems to which it is best adapted, and some approaches to…

This report for researchers in rural sociology develops a conceptual and analytic framework for evaluating policies or programs through interrelated models. Three models--structural analysis, control programming, and simulation--allow researchers to assess policy/program impact, determine why expected impacts did or did not occur, and modify…

This paper is the result of a feasibility study on the implementation of computer-assisted-instruction (CAI) for the U.S. Army Bands. The study analyzes the state-of-the-art capabilities of CAI with regard to Army requirements. The contract for the study states: "The objective of this task is to explore and analyze alternate approaches to…

This paper describes and illustrates a simulation model for the processing of grammatical elements in a sentence, focusing on one aspect of sentence comprehension: the assignment of the constituent elements of a sentence to the correct thematic case roles. The model addresses questions about sentence processing from a perspective very different…

Problem solving is an essential skill in the study of genetics. Genetics problems have traditionally come from laboratory activities and textbook situations. Recently computer-based problems have been available to complement these standard sources. This report focusses on the use of computer-based problems in the study of genetics. Discriptions…

With the help of widely available microcomputers, it is possible to demonstrate certain statistical phenomena which students of statistics are usually expected to take on faith. Two demonstrations are described. In the first demonstration, three common types of sampling (simple random, biased, and stratified-random) are used to compare statistics…
