Presents the results of a manual simulation, which consisted of a simple world model with several feedback loops, to emphasize the particular difficulty of the results of interpreting computer simulations using similar techniques. (CMV)

Reviews the problems of classifying gaming techniques and suggests a heuristic approach as one solution. Definitions of simulation, models, role, and game and play are discussed to help develop a classification based on a technique called gaming simulation. (Author/LRW)

Describes uses of computer simulations for the context of human service program evaluation. Presents simple mathematical models for most commonly used human service outcome evaluation designs (pretest-posttest randomized experiment, pretest-posttest nonequivalent groups design, and regression-discontinuity design). Translates models into single…

Discusses an algorithm for developing problem solving simulations using microcomputers, and describes both the components of the simulation algorithm and the user interface. Examples of simulation and programming methods are presented. (MBR)

The macroeconomic model in Ray C. Fair's textbook, "Specification, Estimation, and Analysis of Macroeconometric Models" (Cambridge: Harvard University Press, 1984), has been programed to run on a personal computer. The model consists of 128 equations. The model's potential for use as a teaching tool is discussed. (RM)

Reports on the Generating Long-term Options by Using Simulation (GLOBUS) computer simulator, which creates models of the world to 2010 taking into account variable actions and behaviors. States that simulations to date permit limited optimism for the next 20 to 40 years. (CH)

An economic simulation in which the classroom is organized like the world of work, with the teacher as employer and the students as paid employees; is an excellent way to prepare students for the world of work and to get them to help with routine classroom chores. (RM)

A simulation design to help undergraduates link theory with practice as they explore curriculum models in depth, then incorporate components from each in developing their own model. (MS)

A Bayesian approach to the evaluation of person fit in item response theory (IRT) models is presented. In a posterior predictive check, the observed value on a discrepancy variable is positioned in its posterior distribution. In a Bayesian framework, a Markov Chain Monte Carlo procedure can be used to generate samples of the posterior distribution…

The purpose of this study was to investigate the effects of sample size on the power of five selected fit indices through a Monte Carlo simulation. Two models (a reduced and a complete model) and 6 sample sizes (20, 50, 100, 200, 500, and 1,000) were used to investigate the effect on the power of fit indices as the sample size was varied. The…

The robustness of the polytomous Item Response Theory (IRT) model to violations of the unidimensionality assumption was studied. A secondary purpose was to provide guidelines to practitioners to help in deciding whether to use an IRT model to analyze their data. In a simulation study, the unidimensionality assumption was deliberately violated by…

This paper summarizes the findings of a research project that was designed to assess the utilization of computer simulation models in the administration of higher education. (Author)

Twenty-four company position models were developed as career-cluster office experience materials. Each contained a student-employee kit and a teacher-supervisor kit. These occupational models were flexible, good substitutes for cooperative programs, and particularly helpful to the less-than-average ability student. (AG)

A simulation of the U.S. Supreme Court procedures and activities, designed to maximize gains in the areas of teaching, research, prediction, and motivation, is described. Instructions given for implementing the Temple University model in the classroom include suggested variations for particular situations. (SM)
