Examined the effects of using Logo or problem-solving oriented simulation software on the spatial and critical thinking skills of fifth graders. Found that the Logo group had a significant pretest-posttest change in spatial scores, and the Simulation group had a significant pretest-posttest change in critical thinking scores. No significant change…

Discusses the use of multimedia software and the need to apply constructivist theories so students become more involved with the software, progressing from simply watching presentations to creating simulations. A project-based learning environment that uses MicroWorlds software is described that focuses on marine biology and oceanography. (LRW)

Compares dyads of secondary school physics students working on a collaborative modeling task using a text-based model representation, in which correct equations are required to make the model run, with others using a graphical representation, in which the model is build by qualitatively linking variables. (MES)

Examines the use of a computer-mediated simulation for the purpose of teaching higher education administration and organization. Describes Virtual University, a computer interactive software program which simulates the management of institutions of higher education to help students better understand colleges and universities as complex…

Discusses the use of multimedia computer-based training to effectively teach mechanical skills. Gives an example of teaching shaft alignment tasks that combines three-dimensional animations, simulations, and user interactions to allow the trainee to practice recognition and manipulation skills. (Author/LRW)

Introduces the Enviroland computer program which features lab simulations of theoretical calculations for quantitative analysis and environmental chemistry, and fate and transport models. Uses the program to demonstrate the nature of linear and nonlinear equations. (Author/YDS)

Describes item response and information functions for the Zinnes and Griggs paired comparison item response theory (IRT) model (1974) and presents procedures for estimating stimulus and person parameters. Monte Carlo simulations show that at least 400 ratings are required to obtain reasonably accurate estimates of the stimulus parameters and their…

Reports on the findings of a study designed to develop three-dimensional virtual reality technology (VRT) learning programs for middle school students and evaluate the program's educational value. Focuses on the topic of structure and function of the eye. Concludes that VRT simulations allow comfortable interaction with computers and increase the…

This article identifies realistic, research-based computer simulations that are capable of stimulating student decision making. Also discussed is a recent category of computer programs, probeware. Students use a sensing device (probe) to measure physical characteristics and transmit results to a computer which collects, stores, and displays the…

The structure, execution, uses, and software specifications for this spreadsheet file are discussed. Availability and modifications of this program are described. (CW)

Discusses a laboratory exercise simulating the paths of light rays through spherical water drops by applying principles of ray optics and geometry. Describes four parts: determining the output angles, computer simulation, explorations, model testing, and solutions. Provides a computer program and some diagrams. (YP)

In applying I. I. Bejar's method for detecting the dimensionality of achievement tests, researchers should be cautious in interpreting the slope of the principal axis. Other information from the data is needed in conjunction with Bejar's method of addressing item dimensionality. (SLD)

A method of assessing rater reliability via a design of overlapping rater teams is presented. Covariances or correlations of ratings can be analyzed with LISREL models. Models in which the rater reliabilities are congeneric, tau-equivalent, or parallel can be tested. Two examples based on essay ratings are presented. (TJH)

A study assessed the effects of three teaching strategies that incorporated a microcomputer component: (1) tutorial, (2) drill and practice, and (3) simulation. Each strategy was compared with one another and with the traditional lecture/discussion method. Student achievement and attitudes were essentially equal in all four methods. (JOW)

Recounts personal experiences in the design of simulations/gaming for city development and planning. Notes early games and describes the development of three land use and city growth games. Discusses revisions, conference demonstrations of the games, and collaborative efforts. (AEF)
