Computer simulation of drug formulation problems involves a database of pharmacological properties, chemical stability, and compatibility data on 20 active ingredients, physiological factors and requirements for parenteral solutions, and additives. The user gathers data from the database, formulates a stable and effective solution, and the drug is…

Describes a "hypothetical," a training technique based on a television panel game, in which participants engage in an imaginary scenario that raises issues of concern in adult education practice. Discusses its pertinence to adult learning, compares it to other strategies, and explains how to develop and run a hypothetical. (SK)

Provides a simulation based on Marco Polo's journey. Demonstrates the hardships of 13th century travel by presenting students with difficult choices under challenging and primitive environmental conditions. Includes suggestions for class activities prior to using the simulation. (LS)

Develops models for participants' behaviors in games, simulations, and workshops based on Catastrophe Theory and Herzberg's two-factor theory of motivation. Examples are given of how these models can be used, both for describing and understanding the behaviors of individuals, and for eliciting insights into why participants behave as they do. (11…

Demonstrates the magnitude of an extinction event by using a simulation to illustrate the massive nature of the loss of a family and the number of species that perish to achieve that result. (RT)

Describes a learning activity for clinical psychology classes in which theater arts students create the role of a client. Students are videotaped twice in an interview situation with the actor. Psychology students receive feedback from the instructor. Both actors and students report benefits from the experience. (KO)

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…

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.…

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…

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…
