This research proposes a Web-based version of a lean office simulation game (WeBLOG). The game is designed to be used to train lean concepts to office and administrative personnel. This group belongs to the frequently forgotten side of a lean enterprise. Over four phases, the game presents the following seven lean tools: one-piece flow,…

This work explores the feasibility of proposing universal design guidelines for E-training modules considering aging differences as an important factor. A controlled experiment was designed and conducted to evaluate the effects of module design characteristics on information recall, satisfaction, disorientation, and task workload, and the…

SystemC is a system-level design and simulation language based on C++. We've been using SystemC for computer organization and design projects for the past several years. Because SystemC is embedded in C++ it contains the powerful abstraction mechanisms of C++ not found in traditional hardware description languages, such as support for…

Physics instruction that is student oriented will generate a long-term individual interest and therefore a lifelong openness to science. Phenomena of nature are part of the fields of interest which provide context leading to greater student interest. In this paper we present the locomotion of fish and sperm in a way which can be used to teach in…

Computer and video games have recently attracted significant attention from educators as a medium for learning. Clark's (2007) critique of the "Serious Games" movement provides a set of useful guidelines for moving that particular industry forward. This article argues for another way of framing the emerging field, as "Games, Learning, and…

In this study, the authors assess several strategies created on the basis of the Mantel-Haenszel (MH) procedure for conducting differential item functioning (DIF) analysis with small samples. One of the analytical strategies is a loss function (LF) that uses empirical Bayes Mantel-Haenszel estimators, whereas the other strategies use the classical…

This lab is a computer simulation of transmission genetics. It presents students with a genetic phenomenon--the inheritance of a randomly--selected trait. The students' task is to determine how this trait is inherited by designing their own crosses and analyzing the results produced by the software.

Used Johnson's transformation (N. Johnson, 1978) with approximate test statistics to test the homogeneity of simple linear regression slopes in the presence of nonnormality and Type I, Type II or complete heteroscedasticity. Computer simulations show that the proposed techniques can control Type I error under various circumstances. (SLD)

Used computer simulation methods to examine the sensitivity of model fit criteria to misspecification of the first-level error structure in two-level models of change and to examine the impact of misspecification estimates on the variance parameters, estimates of the fixed effects, and tests of the fixed effects. Discusses problems caused by…

Describes a cost-effective way to create an effective simulation for students that teaches them how personal computers are used in the workplace. (JOW)

A computer-assisted, K-fold cross-validation technique is discussed in the framework of canonical correlation analysis of randomly generated data sets. Analysis results suggest that this technique can effectively reduce the contamination of canonical variates and canonical correlations by sample-specific variance components. (Author/SLD)

Develops a cultural transmission model with the following variables: worker entry and exit rate, organization growth rate, recruiting selectivity, socialization intensity, and the rate that socialization decays if not reinforced. A computer simulation of the model found that cultural systems in organizations are highly robust and reach equilibrium…

Describes SimSum (Simulation of Summarizing), which simulates 20 real-world working steps of expert summarizers. Presents an empirically founded cognitive model of summarizing and demonstrates that human summarization strategies can be simulated. Discusses current research in automatic summarization, summarizing in the World Wide Web, and…

Computer simulations used to compare the Mahalanobis distance procedure with the Andrews-Pregibon statistic for identifying multivariate outliers result in the conclusion that the choice of procedure is not critical, since both identified valid data points as outliers. Results with false outliers as the dependent variable suggest the importance of…

Computer simulation indicated that reliability increased with the degree of similarity between underlying and observed distributions when the observed categorical distribution was deliberately constructed to match the shape of the underlying distribution of the trait being measured. Reliability also increased with correlation among variables and…
