This discussion of teaching science as a design activity emphasizes open-ended problem solving. Highlights include the relationship between teachers and students; hypotheses as solutions; and descriptions of four microworlds, or computer simulations, in chemistry, geography, physiology, and genetics which use graphic interfaces.

The purpose of this study was to use realistically simulated data to evaluate various CAT designs for use with the verbal reasoning measure of the Medical College Admissions Test (MCAT). Factors such as item pool depth, content constraints, and item formats often cause repeated adaptive administrations of an item at ability levels that are not…

Maintaining that educators need a functional understanding of the brain and how it operates in order to teach effectively and to critically analyze the vast amount of neuroscientific information being published, this book provides information on brain-imaging techniques and the anatomy and physiology of the brain. The book also introduces a model…

Operational gaming techniques that are permeating the architectural profession are used to: elicit user needs, represent architectural realities in the classroom, understand the rationale behind complex design decisions, and model decision environments at many levels with coarse or refined data. (MLW)

Builds on a National Science Foundation (NSF) microcomputer based laboratory project to introduce system dynamics into the precollege setting. Focuses on providing students with powerful and investigatory theory building tools. Discusses developed hardware, software, and curriculum materials used to introduce model building and simulations into…

Presents an alternative model for using the computer as an aid in teaching mathematics. Highlights include a mathematics teaching model; computer software for drill and practice, tutorials, simulation, games, and computer managed instruction; integrating computers into the mathematics curriculum; and examples of computer activities for…

This paper presents Petri net software tool P3 that is developed for training purposes of the Architecture and organization of computers (AOC) course. The P3 has the following features: graphical modeling interface, interactive simulation by single and parallel (with previous conflict resolution) transition firing, two well-known Petri net…

In this article, the author discusses the use in policy analysis of models that incorporate uncertainty. He believes that all models should consider incorporating uncertainty, but that at the same time it is important to understand that sampling variability is not usually the dominant driver of uncertainty in policy analyses. He also argues that…

An interactive training model called SAVR (Safety in Construction Using Virtual Reality) was developed to train construction students, novice engineers, and construction workers to prevent falls from scaffolding. The model was implemented in a graphics supercomputer, the ONYX Reality Engine2. The SAVR model provides trainees with an immersive,…

Virtual worlds technology (VWT) uses special computer hardware and software to link humans with computers in natural ways. A data model, or virtual world, is created and presented as a three-dimensional world of sights and sounds. The participant manipulates apparent objects in the world, and in so doing, alters the data model. VWT will become…

The Southern Rural Development Center in cooperation with the University of Kentucky sponsored a workshop which brought together extension and research personnel interested in rural economic development concerns (i.e., inadequate water supplies, sewer systems, and schools). The proceedings include "Community Growth Management: The Land-Grant…

Computer simulations of agricultural finance and management may be helpful to students preparing for agricultural careers. Simulations would provide problem definition and problem solving in realistic interactions with complex and ambiguous situations similar to those encountered in farming. The paper describes a major financial problem for…

This teacher-coordinator manual assists in planning, organizing, directing, and evaluating student learning experiences associated with either a model store, school store, or combination. (A model store in a marketing laboratory simulates marketing functions; the school store markets merchandise to fellow students, faculty, and/or the public.)…

A highly technical report describes higher education forecasting procedures used by the State Education Department of New York at Albany to project simulated college enrollments for New York State from 1978-1994. Basic components of the projections--generated for full- and part-time undergraduates, full- and part-time graduates, and…

The document describes the development of a library of 24 North Dakota Occupational Models, each patterned after a specific job in a specific office. A teacher's manual giving tips on implementing the program was also developed. The models were designed to provide high school students with a realistic introduction to a variety of office work and…
