Review of the use of simulations and games in communication education over the past 25 years focuses on the nature of participation in simulations and games, the importance of debriefing, and implications of both for the relationships between students and teachers in the classroom. (LRW)

Effects of different weighting schemes on selecting the optimal number of observations in multivariate-multifacet generalizability designs are studied when cost constraints are imposed. Comparison of four schemes through simulation indicates that all four produce similar optimal values and that reliability should be similar. (SLD)

Rasch model total-fit statistics and between-item fit statistics were compared for their ability to detect measurement disturbances through the use of simulated data. Results indicate that the between-fit statistic appears more sensitive to systematic measurement disturbances and the total-fit statistic is more sensitive to random measurement…

Describes QMaPS (Qualitative Matching and Prediction system for Simulations), a qualitative reasoning system designed to function as a module in exploratory simulation learning environments. Highlights include a hierarchical organization of variables; multilevel relation typology; modeling of physical and conceptual domain structures; an…

Describes activities that allow students to work cooperatively to analyze and study evidence from crime scenes and archaeological digs. The activities demonstrate to students the interdependence of a variety of disciplines in the real world. (ZWH)

A simulation exercise consisting of 12 stages corresponding to the life-stages of an enterprise is used as a language-learning technique for business French. The exercise develops both language and networking skills while presenting a creative challenge to students. (MSE)

An extension to the partial credit model, the linear partial credit model, is considered under the assumption of a certain linear decomposition of the item x category parameters into basic parameters. A conditional maximum likelihood algorithm for estimating basic parameters is presented and illustrated with simulation and an empirical study. (SLD)

Activity in which students act out process of protein synthesis is described. An overview of the events and a demonstration of some simple errors that may occur in the process are included. The simulation has been designed so that each student in a class has at least 1 specific role to play and requires from 20 to 40 students. (KR)

A probabilistic parallelogram model (the PARELLA model) is presented for the measurement of latent traits by proximity items. This unidimensional model assumes that the responses of persons to items result from proximity relations. The model is illustrated in an analysis of three empirical datasets from previous studies. (SLD)

Describes exercises that can uncover the assumptions underlying educational practice: (1) scenario analysis; (2) critical debate; (3) simulations of crisis decisions; (4) identifying heroes and villains; and (5) analysis of critical incidents. (SK)

Monte Carlo methods were used to evaluate the degree to which canonical function and structure coefficients may be differentially sensitive to sampling error. For each of 64 research situations, 1,000 random samples were drawn. Both sets of coefficients were roughly equally influenced; some exceptions are noted. (SLD)

The implications of serially correlated effects on the results of generalizability analyses are discussed. Simulated data are provided that demonstrate the biases that serially correlated effects introduce into the results. Serial correlation in measurement effects can have a marked influence on the impression of the dependability of measurement…

Two joint maximum likelihood estimation methods (LOGIST 2B and LOGIST 5) and two marginal maximum likelihood estimation methods (BILOG and ForScore) were contrasted by measuring the difference between a simulation model and a model obtained by applying an estimation method to simulation data. Marginal estimation was generally superior. (SLD)

A modified "F" test is derived that includes a correction for nonindependence of between-groups and within-groups sample values in analysis of variance (ANOVA) designs. Computer simulations based on normal and nonnormal distributions illustrate the usefulness of the approach, which was more powerful than conventional within-subjects…

Developed computer-based rehabilitation caseload management simulation and administered simulation to 18 rehabilitation students and 18 rehabilitation counselors. Performance was evaluated using six caseload management performance indicators. Performance indicators, derived from computer simulation, were found to be effective in differentiating…
