The purpose of this study was to develop a framework for analyzing and evaluating student-constructed models of physical phenomena and monitoring the progress of these models. Moreover, we aimed to examine whether this framework could capture differences between models created using different computer-based modeling tools; namely, computer-based…

As graphically driven, animated, interactive applications offer educators new opportunities for shaping course content, new avenues for research arise as well. Along with these developments comes a need to study the effectiveness of the individual tools at our disposal as well as various methods for integrating those tools in a classroom setting.…

Discussion of factors to be considered in selecting desktop publishing software for the Macintosh microcomputer focuses on the two approaches to such software, i.e., batch and interactive, and three technical considerations, i.e., document, text, and graphics capabilities. Some new developments in graphics software are also briefly described. (MES)

Discussion of the factors that should be considered when purchasing or upgrading a microcomputer focuses on the MS-DOS and OS/2 operating systems. Macintosh purchasing decisions are discussed in a sidebar. A glossary is provided. (CLB)

Reviews evaluation standards that are used to assess the quality of projected graphical displays, and discusses their use in evaluating graphs created with computer graphing programs. Design standards for projected graphs are explained, and examples of three types of graphs are shown. (four references) (LRW)

Describes current desktop publishing packages available for microcomputers and discusses the disadvantages, especially in cost, for most personal computer users. Also described is a less expensive alternative technology--desktop typesetting--which meets the requirements of users who do not need elaborate techniques for combining text and graphics.…

Advises educators on judging the quality of maps contained in CD-ROM encyclopedias, atlases, and almanacs. Discussion focuses on spotting inaccuracies and assessing size, color, and fonts. Other considerations include availability of spoken word accompaniment and the ability to manipulate and print geographic images. A table compares strengths and…
