Native English speakers have difficulty determining which form of direct address is appropriate in German, and students also need practice in giving commands to one another. This article describes an easily organized drill covering both areas. (Author/LB)

Reviews the literature on computer simulation modeling for library management and examines whether simulation is underutilized because the models are too complex and mathematical. Other problems with implementation are considered, including incomplete problem definition, lack of a conceptual framework, system constraints, lack of interaction…

Formulae for estimating individual rater reliabilities from analysis of treatment effects are presented and evaluated. Monte Carlo methods illustrate the formulae. Results indicate that large sample sizes, large true treatment effects, and large differences in the actual reliabilities of raters are required for the approach to be useful. (SLD)

A methodological framework is provided for quantitatively integrating Type I error rates and power values for Monte Carlo studies. An example is given using Monte Carlo studies of a test of equality of variances, and the importance of relating metanalytic results to exact statistical theory is emphasized. (SLD)

Y. Takane and J. Sergent developed a model (MAXRT) for scaling same/different judgments and response times (RTs) simultaneously. The adequacy of the assumption that RTs are distributed log-normally is considered, and the effect of a violation of this assumption is investigated via a computer simulation. (SLD)

Describes a simulation that provides a realistic business context and gives participants the opportunity to experience a clash of cultural values. Notes that the participants are divided into three fictional cultures with specific cultural profiles. Notes that the simulation has been successfully used with undergraduates, MBA students, and…

Provides a conceptual framework for information systems (IS) that can be used in AIDS intervention and prevention (AIP). System components are analyzed, including a database, decision support systems (DSS), expert systems, and software; potential applications of ISAIP are suggested; and an example of a system implemented at Wright State University…

Common approaches to examining the relationship between multitrait-multimethod (MTMM) data and variables outside the MTMM data are compared: averaging various means of each trait and estimating LISREL computer program models, and estimating only relationships between MTMM traits and the outside variables. Problems of correlational bias are…

Application of the bootstrap method to complex psychological analysis is illustrated using a simulation experiment with two populations with small and large samples. The method provides variance estimates, allows testing of nested competing models, and gives a preliminary idea about parameter variability. (SLD)

The teaching and learning potential of interactive video (IV) are explored. Some of the programs currently in use are described. The use of IV for simulations, practical work, problem solving, and presentational skills are discussed. (KR)

Creating a stock market simulation for the classroom computer reinforces math skills and can help students gain a good sense of how current events affect the economy, how to manage money and understand profit and loss, and how to use spreadsheet software. (IAH)

Previous person-fit research is extended through explication of an unexplored model for generating aberrant response patterns. The proposed model is then implemented to investigate the influence of test properties on the aberrancy detection power of a person-fit statistic. Difficulties of aberrancy detection are discussed. (SLD)

A reparameterization of a latent class model is presented to classify and scale nomial and ordered categorical choice data simultaneously. The model extension represents a nonhomogeneous population as a mixture of homogeneous subpopulations. Simulated data and data from a magazine preference survey of 347 college students illustrate the model.…

Describes a problem formulated by fourth-grade students about having more pizza for lunch, and the clarifying, predicting, modeling, simulating, comparing, and extending activities that occurred in addressing the problem from a probabilistic perspective. (MKR)

Describes generativity theory based on the probabilities of many behaviors that are in competition and considers its effect on creativity. Topics discussed include previous and current generativity research, including behavior charts and frequency profiles; computer simulations; skills that improve generative processes; and creativity training in…
