Three common methods for equating parameter estimates from binary item response theory models are extended to the generalized grading unfolding model (GGUM). The GGUM is an item response model in which single-peaked, nonmonotonic expected value functions are implemented for polytomous responses. GGUM parameter estimates are equated using extended…

This study investigated statistical properties of the K-index (Holland, 1996) that can be used to detect copying behavior on tests. A simulation study was conducted to investigate the applicability of the K-index for small, medium, and large datasets. In addition, the Type I error rate and the detection rate of this index were compared with the…

This study explored the dangers of item theft in terms of impact on test quality and fairness. Simulations were used to explore the impact of item theft on test taker scores. In the simulation, a simulated, organized group of thieves took the test, memorized the items received, and distributed the items to future test takers. Impact was explored…

The homogeneity test provided by L. Hedges (1982) in meta-analysis has been widely used, mainly to test if the effect sizes share the same variance. Ignoring the intercorrelations among effect sizes affects the Type I error rate. The main purpose of this research was to study the impact of pooling effect sizes on the homogeneity test in effect…

When categorical responses were simulated from a Multidimensional Many-FACETS Rasch Compensatory Model (MMFRCM), the effects of ability, task difficulty, and step difficulty estimates with the unidimensional Many-FACETS Rasch Model (MFRM; Linacre, 1999) were examined in terms of three error indexes, average absolute difference (AAD), bias, and…

The Delphi method is a means of structuring group communication process so that a group of experts can gather information or forecast future problems effectively. A primary objective of a Delphi study is to obtain consensual and consistent opinions from a group of experts in two or more successive rounds on a given research subject. Consensus and…

The purpose of this study was to assess the dimensionality of attitudinal data arising from unfolding models for discrete data and to compute rough estimates of item and individual parameters for use as starting values in other estimation parameters. One- and two-dimensional simulated test data were analyzed in this study. Results of limited…

Simulation games, defined and described in the article, could be used to improve the quality of adult learning. (AG)

This article describes an approach developed at the Indiana University School of Business which utilizes simulation gaming to make the students aware of the difficulties of both problem solving and problem solution implementation, a task at which universities have been remiss. (JA)

This article seeks to define simulation'' and games'' and finds that in the area of teacher education, instructional activities would be conducted in games while behavioral problems in the classroom deserve simulations. Five of the most common justifications for using situation gaming in teacher education are identified. (JA)

Describes a program prepared in cooperation with the Historical Society of Delaware that was based on total involvement with the students who saw, handled, and worked with actual artifacts of bygone eras. (JA)

This bibliography contains books, articles and papers, bibliographies and directories, periodicals, newsletters and related readings on simulation and games at the college and university levels. (BB)
