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…

Discusses experimental work with computer-simulated microworlds as a means for overcoming the tension between laboratory research and field research in psychology. Topics addressed include characteristics of microworlds; examples of microworlds; and three approaches to research with microworlds, including the individual differences approach, case…

Comparisons of the Wilcoxon test, Friedman test, and repeated-measures analysis of variance (ANOVA) on ranks in a computer simulation show that the Friedman test performs like the sign test whereas the ANOVA performs like the Wilcoxon test. Classification of these tests in introductory statistics textbooks should be revised. (SLD)

Describes two computer-assisted instructional programs (I-View Skills and Goal-Focused Interviewing) and two interactive videodisk (IVD) programs (Crisis Counseling and Group Treatment) designed to teach social work practice skills in introductory interpersonal practice course. Presents programs to encourage other social work faculty and agency…

Describes Design Builder, interactive multimedia software that was developed to enable undergraduate engineers to experience working in a concurrent environment without direct and specialized teaching-staff support, and to provide an interactive and intelligent simulation environment from which users may develop a culture that introduces…

Discusses computer simulation and analyzes evidence concerning the effectiveness of simulation by examining the relationship between two forms of simulations, pure and hybrid; and two modes of instruction, presentation and practice. Presents results of a meta-analysis of 19 studies on simulation effects, including effect size for academic…

Compares traditional mathematical models with computer simulations. Shows the strengths and flexibility of algorithmic computational simulations through a program designed to investigate and extend understanding in one of the most enduring questions in social choice research. Discusses solutions to this problem from each approach--analytic and…

Examines advantages and disadvantages of multimedia simulation in nursing education. Provides an example of a modular design with an integrated intelligent agent and knowledge base for teaching clinical decision making. Concludes that this approach overcomes some of the problems of intelligent tutoring systems. Contains 40 references. (SK)

Describes the Interact project which integrated the distributed hypermedia environment provided by the World Wide Web (WWW) with simulation software to develop reusable education resources that support collaboration across institutions. Discusses benefits of a resource-based design, facilitating and managing the design process in the WWW, and…

Describes the use of object technology for the development of information management systems. Notes the benefits of modelling complex real-world systems and the increases in productivity leading to flexible, reusable, and maintainable software. Discusses problems, support for multimedia data types, and storage capabilities. (AEF)

A strategy is proposed for conceptualizing moderating relationships based on their type (strictly correlational and classically correlational) and form, whether continuous, noncontinuous, logistic, or quantum. Results of computer simulations comparing three statistical approaches for assessing moderator variables are presented, and advantages of…
