D. W. Zimmerman argues that the interpretation by J. D. Gibbons and S. Chakraborti of recent simulation results and their recommendations are misleading and suggests use of an alternate test when homogeneity of variance and normality are violated. Gibbons and Chakraborti review their differences with Zimmerman's position. (SLD)

Developed Computerized Counseling Simulation, simulation of client-counselor interaction. Tested simulation on seven groups with varying degrees of counseling experience: counselors, predoctoral counseling interns, counseling students, first-year counseling students, student peer counselors, undergraduates, and noncounselors (total n=108). Interns…

The effect that collapsing ordered polytomous variable scales has on structural equation measurement model parameter estimates was examined. Four parameter estimation procedures were investigated in a Monte Carlo study. Collapsing categories in ordered polytomous variables had little effect when latent projection procedures were used. (SLD)

The adequacy of multidimensional trait and item parameters using multidimensional item response theory analysis was studied through simulation using different degrees of correlation between two trait dimensions and the existence of a restricted trait on the second dimension. Conditions allowing adequate recovery of trait and item parameters are…

To teach community health assessment to nursing students, videotaped segments of real community situations were incorporated in an interactive simulation program that leads students through the processes of data collection and evaluation. (SK)

Describes use of a computerized simulation to study prediction in a complex environment (i.e., bus traffic control). Nature of the task, presentation method, number of repetitions, and length of time taken for prediction were measured. Prediction was significantly affected by all factors except number of repetitions. No learning effect was…

Studied differences in pointing accuracy in computer-simulated mazes as a function of maze complexity and training effects. Results with 219 college students indicate that, although pointing accuracy remained higher for men, pointing performance can be modified by experience. (SLD)

Use of games in computer-based training (CBT) can enliven material, encourage discovery and experiential learning, and make visceral connections for learners. However, humor can offend or wear thin, and games can be perceived as playing rather than as learning. (JOW)

In Scotland, one "value added" (VA) indicator of secondary school effectiveness measures students' relative "progress" between Standard and Higher grade in particular subjects. When random nonschool factors affecting students' geography performance were computer-simulated to determine VA fluctuation over 25 years, the…

Explores the use of computer simulation/modeling programs for teaching a variety of science concepts. (Author/CCM)

Discusses the evaluation of interactive information retrieval (IIR) systems and explains two main approaches, system-driven and user-centered. Describes Text Retrieval Conference (TREC), and concludes that the simulated work task situation as an experimental sub-component could be recommended for future evaluation of IIR systems based on empirical…

Marketing students (n=99) used computer simulation, 34 did not. Students who performed well on traditional exams also did well on the simulation. Students who preferred working with others seemed to perform more poorly on both the exam and the simulation. (SK)

Interactive digital video enables computer visualization techniques that help students to collect, analyze, and model two-dimensional motion data. This article describes and evaluates five activities developed for the physics classroom with the use of this technology in mind. Activities explore concepts such as space, time, frames of reference,…

In a simulation study of ability and estimation of differential item functioning (DIF) in computerized adaptive tests, Rasch-based DIF statistics were highly correlated with generating DIF, but DIF statistics tended to be slightly smaller than in the three-parameter logistic model analyses. (SLD)

Describes a lesson that outlines a statistics/probability investigation into some aspects of past performance in snooker (a billiards game) using the random number generator on a graphing calculator. (MKR)
