Reports on emergence of decision support system (DSS) as a practical approach for applying computers and information to problems facing management. Information processing and decision making in organizations, simulation-model-based DSS in management of library resource sharing networks, and a resource-sharing simulation system are highlighted.…

Describes an Apple computer program (listing available from author) which simulates Fraunhofer and Fresnel diffraction using vector addition techniques (vector chaining) and allows user to experiment with different shaped multiple apertures. Graphics output include vector resultants, phase difference, diffraction patterns, and the Cornu spiral…

Discusses the realities of implementing a computer-assisted program in high school level science classes, offering some practical suggestions for making such a program successful. Also includes information on several software packages for interfacing microcomputers to sensing equipment. (JN)

This study involved students using simulation software in all phases of the learning cycle. Research on the use of simulations in science education has shown that the simulations can be used effectively in preinstructional and exploratory activities. Preinstructional and exploratory activities elicit and challenge students' alternative…

This study focuses on alternative ways of thinking about the experiences of two cohorts of high school students participating in separate political simulations, one about peace negotiations in the Middle East (the Arab-Israeli Conflict simulation, or AIC), and one focusing on domestic American policy issues (the Conflix Project, or Conflix). Both…

A Web-based learning community involves much more than putting learning materials into a Web site. It can be seen as a complex virtual organization involved with people, facilities, and cyber-environment. Tremendous work and manpower for maintaining, upgrading, and managing facilities and the cyber-environment are required. There is presented an…

These instructions describe the use of BRIDGE, a computer software simulation model that is designed to compare the costs of expanding a college campus using distributed instruction (television or asynchronous network courses) versus the costs of expanding using lecture/lab type instruction. The model compares the projected operating and capital…

Learner-centered software design (LCSD) guides the design of tasks, tools, and interfaces in order to support the unique needs of learners: growth, diversity and motivation. This paper presents a framework for LCSD and describes a case study of its application to the ScienceWare Model-It, a learner-centered tool to support scientific modeling and…

Presents a summary of responses to a brief survey of physiology chairpersons (N=117) on use of computer-based education (CBE) materials in physiology and an overview of discussions that occurred at a workshop focusing on this topic. Indicates that the popular use of materials is for simulations of physiological systems. (JN)

Describes an automated scoring algorithm for a computer-based simulation examination of physicians' patient-management skills. Results with 280 medical students show that scores produced using this algorithm are highly correlated to actual clinician ratings. Scores were also effective in discriminating between case performance judged passing or…

Describes a study that investigated whether an advance organizer could facilitate learning in a computer simulation environment using HyperCard. It examined the differential effectiveness of an advance organizer across three different grade levels--fifth, sixth, and seventh. Analyses of data showed significant differences between the organizer and…

At the introductory level, the computer provides an effective alternative to using animals for laboratory teaching. Computer software can simulate the operation of multiple organ systems. Advantages of software include alteration of variables that are not easily changed in vivo, repeated interventions, and cost-effective hands-on student access.…

Evaluates the effectiveness of an interactive computer-assisted learning program for undergraduate students that simulates experiments performed using isolated, everted sacs of rat small intestine. The program is designed to offer an alternative student-centered approach to traditional laboratory-based practical classes. Knowledge gain of students…

Examines a lesson in which students are engaged in inquiry in evolutionary biology to develop better understanding of concepts and reasoning skills necessary to support knowledge claims about changes in the genetic structure of populations known as microevolution. Explains how a software simulation, EVOLVE, can be used to foster discussions about…

Discusses the systems thinking approach that uses microcomputer-based simulations and modeling to enhance teaching and learning activities in middle school and high school instruction. Particular focus is placed on the Systems Thinking and Curriculum Innovation Network project, part of a longitudinal study managed by Educational Testing Service.…
