Presents a learning system paradigm which uses a multiplicity of toys and simulated models to reinforce concepts in business management and production. Describes concrete learning tools and experiences for each component of a proposed instructional paradigm: measurement, efficacy, data development, imagery and integration, computerization,…

Discusses the use of simulation, a form of interactive multimedia training that re-creates the work environment to a degree of near realism, as a training method. Discusses the benefits of simulations and the cost and process of developing materials. (JOW)

Provides guidelines for performing and evaluating a simulation developed to teach business students how to conduct effective meetings and how to write memos in the realistic context. Includes handouts that guide students in performing the simulation. (SR)

Sixty-three college students worked with a computer simulation in which gradually increasing model complexity (model progression), model progression plus small assignments, or a control condition without either were used. Definition knowledge increased for all three conditions, but intuitive knowledge gain was greater for the two experimental…

Discusses fitting multivariate normal mixture distributions to structural equation modeling. The model used is a LISREL submodel that includes confirmatory factor and structural equation models. Two approaches to maximum likelihood estimation are used. A simulation study compares confidence intervals based on the observed information and…

Describes Science Technology and Society (STS) simulations that teach students about human experiences involving controversial issues. When students are taught using controversial and authentic issues, science instruction becomes current and engaging. (SAH)

This study examined issues in supporting middle school teachers to become more learner centered when implementing computer-based, workplace simulations in their classrooms. Focuses on a participant observation study of two teachers to develop and evolve a framework for professional development that included reflective skills and proximal goals.…

Simulations demonstrate the effects of correlated errors on the person-by-occasion design in which the confounding effect of equal time intervals results in correlated error terms in the linear model. Two specific error correlation structures were examined. Conditions under which underestimation and overestimation occur are discussed. (SLD)

High school students (92 females, 127 males) using Krumboltz Job Experience Kits (occupational simulations) experienced 6 diverse jobs in random order and recorded reactions on the Perceived Congruency Questionnaire. Results supported Holland's hexagonal model, indicating that different personality types react to different jobs in accord with the…

Presents several theoretical solutions to a geometry problem involving circles and probability. Includes simulation procedures to estimate the solutions. (MKR)

The Rasch Poisson counts model is a latent trait model for the situation in which "K" tests are administered to "N" examinees and the test score is a count (repeated number of some event). A mixed model is presented that applies the EM algorithm and that can allow for missing data. (SLD)

Hypothesizes that the construction of visual models, resolution of these visual models with numeric models and, in many cases, rejection of commitments such as the belief in one true velocity, are necessary for students to form integrated mental models of relative motion events. Studies high school students' relative motion problem solving.…

Used Monte Carlo simulation to compare the relative measurement efficiency of polytomous modeling and dichotomous modeling under different scoring schemes and termination criteria. Results suggest that polytomous computerized adaptive testing (CAT) yields marginal gains over dichotomous CAT when termination criteria are more stringent. Discusses…

Developed a new classification method for the logistic regression (LR) procedure for differential item functioning (DIF) based on methods used in the Simultaneous Item Bias test and conducted a simulation study to determine if the effect size measure affects the Type I error and power rates for the LR DIF procedure. Results show that inclusion of…

In a simulation, a student team studied a real factory system and tested three work configurations. The partnership benefitted students and business, but the project underscored the need for careful coordination, assistance from company management and instructors, and a longer time frame than a semester.
