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)

Used simulations of computerized adaptive tests to evaluate results yielded by four commonly used ability estimation methods: maximum likelihood estimation (MLE) and three Bayesian approaches. Results show clear distinctions between MLE and Bayesian methods. (SLD)

Contrasts "mental models" used by automated scoring for the simulation division of the computerized Architect Registration Examination with those used by experienced human graders for 3,613 candidate solutions. Discusses differences in the models used and the potential of automated scoring to enhance the validity evidence of scores. (SLD)

This introduction to a special issue on play and simulation/gaming examines the distinction often made between children's play and adult gaming. It illustrates the diversity of play activities and the pedagogical uses of gaming, and demonstrates that these two fields of reflection have everything to gain through mutual enrichment. (AEF)

One way to assist students in developing correct intuitive ideas about the effect of sample size is to allow students to simulate similar problems. Describes experiences with classes performing simulation using graphing calculators. (ASK)

Investigated Type I error rates of the likelihood-ratio test for the detection of differential item functioning (DIF) using Monte Carlo simulations under the graded-response model. Type I error rates were within theoretically expected values for all six combinations of sample sizes and ability-matching conditions at each of the nominal alpha…

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…

Carried out simulations in which a set of morphologically-related words varying in semantic transparency were embedded in either a morphologically rich language (Hebrew) or an impoverished artificial language. Found that morphological priming increased with degree of semantic transparency in both languages. (Author/VWL)

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

Describes a classroom demonstration called the Gambler's Fallacy where students in an introductory psychology statistics class participate in simulated gambling using weekly results from professional football game outcomes over a 10 week period. Explains that the demonstration illustrates that random processes do not self-correct and statistical…

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…
