The level of standardized effect sizes obtained by chance and the use of significance tests to guard against spuriously high standardized effect sizes were studied. The concept of the "protected effect size" is also introduced. Monte Carlo methods were used to generate data for the study using random normal deviates as the basis for sample means…

Previous studies that investigated the effect of unequal ability distributions on the Type I error (TIE) of the Mantel-Haenszel chi-square test for detecting differential item functioning (DIF) simulated ability distributions that differed only in means. This simulation study suggests that the magnitude of TIE inflation is increased, and the type…

One set of approaches to the problem of clustering with dichotomous data in cluster analysis (CA) was studied. The techniques developed for clustering with binary data involve calculating distances between observations based on the variables and then applying one of the standard CA algorithms to these distances. One of the groups of distances that…

ERG--the Energy Resources Game--is a computer based game which explores questions regarding regional energy supply and demand, such as population and economic growth goals; acceptable levels of dependence on imported energy; and acceptable levels of environmental impact. (JA)

A simulation of a buying service for a number of retail stores, termed FLAIR, is described as a flexible instructional vehicle meeting the needs of business procedures trainees attending the Southern California Regional Occupational Center. Training objectives, office organization, and the importance of real-world simulation in developing…

A mock trial activity reflects the actual practice of plea bargaining which is used to reduce the heavy load of cases in the courts. (Author/KM)

Describes four systematic techniques of future forecasting which could be useful in social planning extrapolation, Delphi forecasting, simulation, scenario-speculation. (Author/NJ)

The potential for simulation teaching of special library administration has attracted interest in library education circles. The nature of the models needed for this kind of teaching and the process of designing them are described. (18 references) (Author)

Described is an inductively taught educational program (Education Through Inquiry) designed for students who have difficulty reading and writing. (MM)

Discusses a computer simulation model for comparing the impact of two partially decentralized school finance systems: the District Power Equalizing (DPE) system, and the Family Power Equalizing (EPE) finance system. (EM)

Simulation, gaming, and role playing are becoming popular in secondary schools throughout the country. The authors, a special interest group at the University of Kentucky, attempt to clarify the differences among these activities to help administrators and teachers understand what is involved in each. (Editor/CB)

Simulating the past through role playing is not necessarily new in or classrooms, but the daily practice of recognizing the emotions of the past as a guide for living is a most useful approach to a very old problem of knowing thy self. (Author)
