A probabilistic item response theory (IRT) model is developed for pair-comparison design in which the unfolding principle governing the choice process uses a discriminant process analogous to Thurstone's Law of Comparative Judgment. A simulation study demonstrates the feasibility of estimation, and two examples illustrate the implications for…

Presented are suggestions for simulations for students in grades 3-12, designed to promote an understanding of how individuals with handicaps cope and adapt to their disability. Simulation ideas include toothbrushing while blindfolded and dressing with socks covering the hands. A participant's reaction form and an observer's reaction form are…

Shows that graphs can reveal much about feedback systems that formula conceal, especially as microcomputers can provide complex graphs presented as animations and allow students to interact easily with them. Describes feedback systems, evolution of the system, and phase diagram. (YP)

Explains a computer simulation on post-revolutionary Russia in which students must make decisions in order to retain power and improve the economy. Decision areas include improving agricultural productivity, increasing industrial productivity, and establishing the production of consumer goods. (LS)

A procedure--based on item response theory--for testing the hypothesis of unidimensionality of the latent space is proposed. Use of the procedure is supported by an asymptotic theory and a Monte Carlo simulation study. The procedure tests for unidimensionality in test construction and/or compares two tests. (SLD)

Illustrates some of the practical issues and problems connected with the design and use of computerized business games by describing three games which have been developed and operated by staff at Leeds Polytechnic Department of Business Management (United Kingdom). Sample input and output forms are included. (nine references) (LRW)

Describes a simulation exercise that integrates current events with the basics of decision making under crisis. Reports positive results in terms of student participation, interaction and reflection while creating minimal demands on class time. Provides details for using the simulation. (KO)

John F. Khanlian, Ericka B. Gray and Sandi Dittrich offer a role playing activity on mediation. Jo Ellen Ambrose's and John Nelson's lessons deal with arbitration. Lowell Ueland's simulation is concerned with plea bargaining, and Jack Hanna's activity involves a discussion of lawyer responsibility to provide pro bono services. (KO)

Presents model of instructional strategy planning that links specific cognitive learning and thinking processes with specific computer-based instructional strategies. Topics discussed include memory systems; types of knowledge; drill and practice; tutorials; task-oriented simulations; problem-oriented simulations; and self directed experiences.…

Discussion of the degree of training effectiveness in management training technologies focuses on a training experiment which employed two scenarios of a computer assisted simulation. Structural components of managerial effectiveness versus specific content of managerial tasks are described, and suggestions for future training technologies are…

Studies the pressure and energy of particles interacting through a Lennard-Jones potential and correlates thermodynamical properties with system structural characteristics. Analyzes the relationships between computer simulated data and the van der Waals equation. (YP)

Supercomputing is described in terms of computing power and abilities. The increase in availability of supercomputers for use in chemical calculations and modeling are reported. Efforts of the National Science Foundation and Cray Research are highlighted. (CW)

Presents an overview of a computerized Decision Support System (DSS) for academic administrators. Following a discussion of its capabilities, the various components of a DSS are examined as well as the development tools needed. Examples follow of DSS in two universities, and various development and implementation issues are considered. (TE)

An Oregon Health Sciences University medical school experiment adapted the quarterly Objective Structured Clinical Examination, in which medical students interact with standardized patients, to accommodate 23 small groups rather than 94 individual students at each testing station. Results indicated the method favorably influenced students,…

Expert systems technology was applied to placement decisions of deaf and hard-of-hearing children. The application involved developing a model of how experts make placement decisions. The decisions of the expert system were found to agree with those of a majority of teachers in 90% of the cases. (DB)
