The focus of this research was to determine the efficacy of a new method of selecting sample sizes for multiple linear regression. A Monte Carlo simulation was used to study both empirical predictive power rates and empirical statistical power rates of the new method and seven other methods: those of C. N. Park and A. L. Dudycha (1974); J. Cohen…

This document, which is intended for high school business teachers, outlines the plan for a course in which students gain hands-on experience in operating a bank in which students actually deposit money. The document begins with a brief course description, rationale, and list of 11 course objectives. Presented next is background information about…

A common practice in some certification fields (e.g., information technology) is to draw items from an item pool randomly and apply a common passing score, regardless of the items administered. Because these tests are commonly used, it is important to determine how accurate the pass/fail decisions are for such tests and whether fairly small,…

This paper aims to describe a Bayesian approach to modeling and estimating cognitive models both in terms of statistical machinery and actual instrument development. Such a method taps the knowledge of experts to provide initial estimates for the probabilistic relationships among the variables in a multivariate latent variable model and refines…

Research discussed in this paper was conducted as part of an ongoing large-scale simulation study to evaluate methods of calibrating pretest items for computerized adaptive testing (CAT) pools. The simulation was designed to mimic the operational CAT Armed Services Vocational Aptitude Battery (ASVAB) testing program, in which a single pretest item…

This project explores the use of narrative to mediate the delivery of information on the effects of harmful discrimination in a simulated environment that is intended to arouse empathy and inspire reflection. It focuses on the potential of instructional narrative simulation to change biased beliefs about homosexuality. "This just is!"…

This simulation study focused on the power of detecting group differences in linear growth trajectory parameters within the framework of structural equation modeling (SEM) and compared this approach with the more traditional repeated measures analysis of variance (ANOVA) approach. Three broad conditions of group differences in linear growth…

The purposes of this study were to: (1) extend the sequential probability ratio testing (SPRT) procedure to polytomous item response theory (IRT) models in computerized classification testing (CCT); (2) compare polytomous items with dichotomous items using the SPRT procedure for their accuracy and efficiency; (3) study a direct approach in…

A simulation game provides a highly versatile model suitable for use is economics, political science or sociology lessons, or in any situation in which conflict of groups or individual interests are being examined. (Author/KM)

This essay explores the methodology of a new discipline, system dynamics, as an approach to the analysis of decisions in education. (Author)

Reported are results of a study which compared a traditional method of teaching office practice with a simulation method using MOE Simulation materials. It was found that using simulation was more effective in developing attitudes and personality traits important to the office worker. (SC)

General and specific directions are provided for the two-week simulation activity designed to acquaint students with laws, lawsuits, courtroom activity, and their relationship to the solution of environmental questions. (Author/SM)

Describes a class project where children found ways to adapt to routines, situations, and events of a real community to a simulated society in the classroom. (GB)

Considered the value of educational simulations in instructional areas and situations. (Author/RK)
