The purpose of this study was to determine differences in learning outcomes of students taught computer applications through supervised laboratory instruction versus video simulation. No differences were observed for time required to complete an application, proper use of commands, or retention of the learned application. (Author)

Describes the application of case analysis to a learner-centered microcomputer-based instructional model. Topics discussed include the use of computer-based case analysis with adult students; case planning; and two sample cases, one a decision-making model and one a technical model.

It is suggested that using an unbiased estimate of the weight matrix may eliminate the small or intermediate sample size bias of the asymptotically distribution-free (ADF) test statistic. Results of simulations show that test statistics based on the biased estimator or the unbiased estimate are highly similar. (SLD)

Explored personal and situational sources of cooperation. Assessed MBA students' disposition to cooperate and randomly assigned them to simulated organizations emphasizing either collectivistic or individualistic cultural values. Coworkers rated cooperative subjects in collectivistic cultures as most cooperative. Cooperative people were most…

Provides commentaries on professional and personal experiences in the development of simulations in the study of international affairs. Describes the evolution in Simulated International Processes projects from a person-machine format to an all-computer simulation. Discusses work with the military, field work, teaching experiences, difficulties,…

Discusses selective fidelity in training devices, when trainers must choose to simulate only the stimuli that are truly necessary to perform a task. Examples of selective fidelity are described from military tactical training devices; and the future of selective fidelity is considered, including behavioral and cognitive research contributions.…

This simulation investigated two procedures that reduce differences between paper-and-pencil testing and computerized adaptive testing (CAT) by making CAT content sensitive. Results indicate that the price in terms of additional test items of using constrained CAT for content balancing is much smaller than that of using testlets. (SLD)

The interact simulation environment has the potential to overcome problems associated with simulations by improving the lack of cost effectiveness, providing online guidance to students, and tailoring the supporting material to suit a wide range of contexts. Results show a flexible teaching and learning environment allows for teacher creativity.…

Presents a Project WET water education activity. Students simulate the movement of water within the water cycle by role-playing a water molecule's movements. Students learn the states of water as it moves through the water cycle. (LZ)

Signal detection experiments with 21 college students suggest that streakiness is a property of auditory and visual discrimination in that correct and incorrect responses have a positive sequential dependency. Monte-Carlo simulations of observed data sequences suggest that streaky performance results from wavelike variations in perceptual and…

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)

Analytical solutions for point and variance estimators of the mediated effect, the ratio of mediated to direct effect, and the proportion of the total effect mediated were determined through simulation for different samples. The sample sizes needed for accuracy and stability are discussed with implications for mediated effects estimates. (SLD)

A modification of Horn's parallel analysis is introduced that is based on the Monte Carlo simulation of the null distributions of the eigenvalues generated from a population correlation identity matrix. This modification reduces the tendency of the parallel analysis procedure to overextract or to extract poorly defined factors. (SLD)

Describes learnings originating from a simple pendulum simulation using "interactive physics" simulations. Discusses tension in the rope, acceleration of the pendulum bob, and initial displacements. (JRH)

Developed and tested the Safety Simulator, a new assessment of science teachers' knowledge of school lab safety management based on Interactive Videodisc Technology. Reports that reliability of scores for the four different categories of lab safety (physical facilities, chemicals, lab techniques, and students' behavior) were found to be moderate…
