Describes the architecture of a distributed, networked, multimedia learning environment for macroeconomics, which employs gaming and simulation methods. Details include a conceptualization of the system and discussion of its function and structure. (JKP)

Includes four articles: "Virtual Reality" (Kopf), description of its uses in computer-assisted design, architecture, and technical training; "SME (Society of Manufacturing Engineers) Robotics Contest Opens Doors to Future" (Wagner); "Superconductivity" (Canady), description of classroom demonstrations and experiments;…

Describes a linguistic analysis computational system that responds to highly complex queries about morphosyntactic and semantic structures contained in large sets of language acquisition data by identifying, displaying, and analyzing sentences that meet the defined linguistic criteria.

Smallest exact confidence intervals for the ability parameter of the Rasch model are derived and compared to the traditional asymptotically valid intervals based on Fisher information. Tables of exact confidence intervals, termed Clopper-Pearson intervals, can be drawn up with a computer program developed by K. Klauer. (SLD)

Six computer applications in education are word processing, computer-assisted instruction, computer-aided design, computer authoring systems, computer data systems, and computer storage. Computers may assist students with three learning stages: acquisition, transformation, and evaluation of information. Advances in computer programing, software,…

Using a Monte Carlo simulation, a bootstrap procedure was evaluated for setting a confidence interval on the unrestricted population correlation (rho) assuming various degrees of incomplete truncation on the predictor. Sample size was the most important factor in determining accuracy and stability. Sample size should be at least 50. (SLD)

Four groups of 24 undergraduates each received the following instruction on logic circuits: (1) lab, then readings; (2) computer simulation, then readings; (3) readings, then lab; and (4) readings, then simulation. Results showed that advance exposure to experiential activity (lab or simulation) aided the learning of unfamiliar technical material…

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)
