Bias and discrimination based on the differences of others is a serious contemporary problem. Biased beliefs often lead to harmful discriminatory action and inhibit emotional and cognitive development. Such beliefs also serve as perceptual screens that constrict imagination, limit experience, and diminish the possibilities of constructing useful…

A Monte Carlo study was conducted to compare the statistical bias and standard errors of non-equivalent-groups linear test equating in small samples of examinees. One thousand samples of each size (15, 25, 50, and 100) were drawn with replacement from each of five archival data files from elementary school and secondary school teacher subject area…

This third of three volumes reports on analytic procedures conducted to address various aspects of the scalar properties of the Device Effectiveness Forecasting Technique (DEFT). DEFT, a series of microcomputer programs applied to data gathered from rating scales, is used to evaluate simulator devices used in U.S. Army weapons training. The…

This paper presents the results of three years of development and evaluation of a CD-ROM/Web hybrid simulation known as Brownfield Action for an introductory environmental science course at an independent college for women in the northeastern United States.

Special attention has been given to the adaptation of computer technology into teaching-learning process for effective learning and increasing students' achievement. In recent years, it has been realized that there is an immense benefit in applying computer technology in the…

The Water and Molecular Networks (WAMNet) Project uses graduate student written Reduced Instruction Set Computing (RISC) computer simulations of the molecular structure of water to assist high school students learn about the nature of water. This study examined: (1) preconceptions concerning the molecular structure of water common among high…

The papers in this collection of 71 individual papers and 3 symposiums represent some of the most current thinking in educational communications and technology. For the first time, a selected number of development papers sponsored by the Division for Instructional Development are included. Topics discussed include the effects of various conditions…

This document consists of three parts. The first part is a report on a project conducted to develop computer software needed by vocational agriculture teachers in Texas. The report details the process used to assess and develop software, and provides guidelines that can be used by others in evaluating computer software for vocational agriculture…

In Dubai, traffic accidents kill one person every 37 hours and injure one person every 3 hours. Novice traffic accident investigators in the Dubai police force are expected to "learn by doing" in this intense environment. Currently, they use no alternative to the real world in order to practice. This paper argues for the use of an…
