An overview is provided of current trends in virtual reality research and development, including discussion of hardware, types of virtual reality, and potential problems with virtual reality. Implications for education and training are explored. (Author/JKP)

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.

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…

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)

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 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…

Describes an instructional simulation of a commercial banking system. Identifies the teaching of portfolio theory, market robustness, and the subtleties of institutional constraints and decision making under uncertainty as the project's goals. Discusses the results of applying the simulation in an environment of local and national markets and a…
