Describes the use of a Macintosh computer and HyperCard software to create an introduction to cell culture techniques that closely approximates a hands-on laboratory experiment. Highlights include data acquisition, data analysis, the generation of growth curves, and electronic modeling. (LRW)

Discusses skill transfer as a human performance issue based on experiences with computerized flight simulators. Highlights include the issue of similarity; simulation and the design of training devices; an information theory of transfer; invariants for flight control; and experiments involving the transfer of flight skills.

SIGMA (Simulation Graphical Modeling and Analysis) is a computer graphics environment for building, testing, and experimenting with discrete event simulation models on personal computers. It uses symbolic representations (computer animation) to depict the logic of large, complex discrete event systems for easier understanding and has proven itself…

Examined psychometric properties of four clinical treatment planning simulations (CTPS) developed by interdisciplinary mental health experts to examine clinical judgment in treatment planning processes of practitioners. Found that scoring reliability was high and simulations demonstrated adequate content, discriminant, and predictive validity.…

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)
