Mathematical analysis and computer simulation methods are used to show that interactive models of context effects can exhibit classical context effects if there is variability in the input to the network or the network itself. Interactive models represent hypotheses about information-processing dynamics leading to the global asymptotic behaviors…

This article suggests a teaching method, the Classic Studies Inquiry Simulation, which allows health educators to use the epidemiologic model to teach critical thinking skills. This technique is demonstrated for teaching major research designs and major rates used in epidemiology. (IAH)

Uses game theory to help practitioners make decisions about educational games, simulations, or workshops whose outcomes depend to some extent on chance. Highlights include principles for making decisions involving risk; elementary laws of probability; utility theory; and principles for making decisions involving uncertainty. (eight references)…

Two forms, pure-rank and mixed-rank, of a nonparametric, general, linear model-based statistic that can be used to test several hypotheses are presented. A Monte Carlo study was used to investigate the distributional properties of these forms, and their use is discussed. (SLD)

Three new developments are sparking renewed enthusiasm for microcomputers among science teachers: teacher-designed software, more powerful hardware, and increased access to teacher inservice and coursework for computer-assisted instruction. Central to tomorrow's science curriculum will be teachers' acting as mentors, facilitators, and…

The unconditional--simultaneous--maximum likelihood (UML) estimation procedure for the one-parameter logistic model produces biased estimators. The UML method is inconsistent and is not a good alternative to conditional maximum likelihood method, at least with small numbers of items. The minimum Chi-square estimation procedure produces unbiased…

The effect of violating the assumption of nonspeededness on ability and item parameter estimates in item response theory was studied through simulation under three speededness conditions. Results indicate that ability estimation was least affected by speededness but that substantial effects on item parameter estimates were found. (SLD)

Describes an inexpensive, easily prepared demonstration to teach the concepts of human blood grouping, antigen-antibody reactions, and medical transfusions. (ZWH)

Through Project EXCEL (Excellence in Community Elected and Appointed Leadership), 63 participants (Ohio county commissioners) completed simulation exercises in 7 assessment centers. Participants received personalized feedback on 15 behavioral dimensions. (SK)

This paper presents an analysis of the stability of principal components. Stability is measured by the expectation of the absolute inner product of the sample principal component with the corresponding population component. The usefulness and predictive validity of the model were supported through simulation. (SLD)

It is proposed that attributes of automatization depend on the strength of a processing pathway, and that strength increases with training. With the Stroop effect as an example, automatic processes are shown through simulation to be continuous and to emerge gradually with practice. (SLD)

Discussion of computer simulations as a form of computer-assisted learning (CAL) focuses on a framework for domain representation for an Intelligent Simulation Learning Environment (ISLE). Topics discussed include knowledge related to computer simulations; formalization of domain knowledge; and the conceptual domain model. (19 references) (LRW)

Describes a computer program that gives Fluxus exhibition attendees an opportunity to experience the Flux objects in the spirit in which they were originally created. Suggests that the computer program provides a virtual approximation to the original art works without damaging them. (RS)

New applications of computer-assisted training being developed include telecommunications, artificial intelligence, soft skills training, and performance support systems. Barriers to acceptance are development time, costs, and lack of human contact. (SK)

The scoring pattern of the Multiple Affect Adjective Check List--Revised (MAACL-R) (M. Zuckerman and B. Lubin, 1985) was studied under "simulate good" and "simulate bad" conditions and under instructional sets of "simulate" or "simulate with caution" with 320 college students. Results show that the MAACL-R…
