Presents an instructional system that integrates computer simulation and computer graphics for economic models presented as equation systems. Describes the Model Laboratory System, an instructional system, developed at the University of Wisconsin at La Crosse. (DB)

Provided are three program listings which may be used to illustrate this fractal figure. Extensions of these algorithms and their use in the study of chaos and fractals are suggested. (CW)

Describes the use of interactive videodiscs in Dutch secondary vocational school departments of pharmaceutical education for testing theoretical knowledge and practical skills in a simulated real-life situation. An example is given, feedback and scoring are explained, and criteria for reliability with a classical text analysis are discussed.…

A theoretical discussion of categorization, unit structures and structured units, and fractions as operators was introduced. The thinking of grade-three students (n=3) with regard to the meaning of fractions was investigated in two teaching episodes using the computer environments of SuperPaint and CopyCat. (Contains 14 references.) (MKR)

Simulated data typical of those from meta analyses are used to evaluate the reliability, Type I and Type II errors, bias, and standard error of the meta-analytic procedures of Schmidt and Hunter (1977). Concerns about power, reliability, and Type I errors are presented. (SLD)

Describes the development of a simulation-based intelligent tutoring system for nurses working in a surgical intensive care unit. Highlights include situative learning theories and models of instruction, modeling expertise, complex decision making, linking theories of learning to the design of computer-based learning environments, cognitive task…

Describes Internet-based online interactive role-playing simulations of current political events that were developed at Macquarie University (Australia) to be used with Internet partners around the world. Discusses the use of e-mail, teleconferences, and evaluation of the simulations. (LRW)

Argues that the creation of distributed environments for constructivist learning is a challenge which requires a multidisciplinary development and support team. Outlines recommended strategies for the collective creation of virtual worlds which can improve learning. Contains 11 references. (Author/WRM)

Describes how to combine computer-assisted learning with collaborative learning in an introductory chemical engineering course in process dynamics and control. Discusses participants' impressions regarding the effectiveness of the approach. (WRM)

Investigates the effects of preservice teachers working in paired-learning conditions versus working independently on a computer-based tutorial/simulation designed to teach users about an electronic-mail system. Findings support previous research on the positive effects of paired learning using computer-based instruction designed for individual…

Describes the development and use of two computer simulations for investigating systems thinking and environmental problem-solving in children (n=92). Finds that older children outperformed younger children, who tended to exhibit magical thinking. Suggests that seemingly isomorphic environmental problems may not be interpreted as such by children.…

Reports on a research project designed to develop an intelligent computer-based learning environment of industrial applications. "Jonas," an expert system, is part of a modeling/simulation environment which enables shop-floor workers to test and put new philosophies of work into practice in the context of manufacture. The approach focuses on the…

Compares humanlike versus machinelike interactional styles of computer interfaces, testing hypotheses that evaluative feedback conveyed through a humanlike interface will have greater impact on individuals' self-appraisals. Reflected appraisals were more influenced by computer feedback than were self-appraisals. Humanlike and machinelike interface…

NASA research into plant-based regenerative systems for sustaining colonies in space provides the core content for the Classroom of the Future (COTF), a NASA sponsored project that transfers research on space exploration to high school biology classrooms. This article describes and evaluates BioBlast (Better Learning through Adventure, Simulations…

Describes some alternatives to dissection offered to teachers through the National Anti-Vivisection Society (NAVS) and other sources. These include models, CD-ROMs, and software that enable students to click on scalpels, scissors, and other instruments to cut through videotaped specimens. Also details the Dissection Hotline and the Dissection…
