Compares retention of popular science material by fifth grade students using either computer simulation software or expository text as the instructional tool. Finds a statistically significant superiority in favor of the expository text group. (RS)

Describes projects developed through the Long Distance Learning Network (LDLN) that experimented with using telecommunications in classrooms in the United States and in other countries. A creative writing project involving elementary school students in the United States, Canada, and Australia is described, and a seventh-grade geography project is…

Discusses the use of the mathematics classroom for discovering the relationship among computers, mathematics, and real-world problems. Provides three probability problems and compares the results of three methods, actual trial, computer simulation, and mathematical solution. (YP)

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…

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)

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)

Describes the PLUTO model, an interactive computer program designed for use in education and training of city planners and engineers. Emphasizes four issues: (1) the balance between realism and simplification; (2) the design of the user interface; (3) comparative advantages of group and solo working; and (4) factors affecting the decision to…

Examines three studies that investigated the use of technology in social studies education: (1) Project ICONS (International Communication and Negotiation Simulation) for college and high school students; (2) a study of sixth graders that used "Archaeotype," a computer simulation archaeological site; and (3) a decision-making study of…
