Describes application of a package of simulations, called MERGE, which simulates four different theoretical explanations of social welfare policy process in a scenario at the local level avoiding ethical and practical limitations of applied theoretical experiments. MERGE is based upon a general simulation system, called EXPER SIM, available from…

Describes a course designed to assist students in writing differential equations to represent chemical processes and to solve these problems on digital computers. Course outline and discussion of computer projects and the simulation and optimization of a continuously stirred tank reactor process are included. (JN)

Describes use of computer-based simulations to evaluate educational and experiential learning as a means of according appropriate credit for clinical nursing courses and facilitating admission and progression within the existing undergraduate curriculum at Ohio State University College of Nursing. (Author/MBR)

Describes a computer program simulating seasonal population growth and decline in a honeybee colony as an ecological teaching aid. Program listing for Pet microcomputers (in BASIC) is included. (JN)

Investigated the relationships between computer-simulated, in-vitro interactional personality behavior and various indices of interpersonal relationships using data collected from 31 families. Analysis showed that strife was allied most closely with rigid, unstable interpersonal interactions. Concluded that the systems approach offers a unique,…

This paper presents a summary of action research investigating statistics students' understandings of the sampling distribution of the mean. With four sections of an introductory Statistics in Education course (n=98 students), a computer simulation activity (R. delMas, J. Garfield, and B. Chance, 1999) was implemented and evaluated to show…

This project explores the use of narrative to mediate the delivery of information on the effects of harmful discrimination in a simulated environment that is intended to arouse empathy and inspire reflection. It focuses on the potential of instructional narrative simulation to change biased beliefs about homosexuality. "This just is!"…

Purdue University (Indiana) is developing a series of computer modules of state-of-the-art chemical engineering processes to serve as the basis for computer-simulated experiments. One, sponsored by Procter and Gamble, models the extraction step in the decaffeination process and allows students to determine the optimal extraction conditions for…

Used computer simulations to examine effectiveness of different criteria for measuring infant visual habituation. Found that a criterion based on fitting a second-order polynomial regression function to looking-time data produced more accurate estimation of looking times and higher power for detecting novelty effects than did the traditional…

Examines computer based simulations of practical laboratory experiments in engineering. Discusses the aims and achievements of lab work (cognitive, process, psychomotor, and affective); types of simulations (model building and behavioral); and the strengths and weaknesses of simulations. Describes the development of a centrifugal pump simulation,…

Major issues related to index-of-fit conjoint analysis were addressed in this simulation study. Goals were to develop goodness-of-fit criteria for conjoint analysis; develop tests to determine the significance of conjoint analysis results; and calculate the power of the test of the null hypothesis of random data distribution. (SLD)

A Monte Carlo study determined the Inverse Scree Test's shape with various numbers of true groups and under different conditions of distribution shape and sample size. Six simulated distributions of 3,000 subjects each and 1 with 1,500 were created. Findings suggest relative distribution independence, number independence, and modest…

Presents a framework identifying the molecular level assumptions underlying many thermodynamic models. Tests the assumptions using theory and computer simulation to develop better assumptions. (YP)

Describes a model for the workload of a full text retrieval system and of a simulation model for a version of an existing system called Full/Text. The effectiveness of various data caching strategies using the 2 models are explored, and the impact of various parameters on the strategies are evaluated. (13 references) (LRW)

Simulation techniques were used to generate conventional test responses and track the proportion of alternatives examinees could classify independently before and after taking the test. Finite-state scores were compared with these actual values and with number-correct and formula scores. Finite-state scores proved useful. (TJH)
