Interactive Web Environments and multimedia tools are very common in engineering studies. However, these resources are very limited when graphical resolution is needed during the learning process. A learning environment that combines video and self-assessment Computer-Aided Design (CAD) tools was developed to analyse this problem and to determine…

The rapid development of computer graphics technology has made possible an easy integration of dynamic visualizations into computer-based learning environments. This study examines the relative effectiveness of dynamic visualizations, compared either to sequentially or simultaneously presented static visualizations. Moreover, the degree of realism…

This study explored computer animation vignettes as a replacement for live-action video scenarios of classroom behavior situations previously used as an instructional resource in teacher education courses in classroom management strategies. The focus of the research was to determine if the embedded behavioral information perceived in a live-action…

Within the framework of cognitive learning theories, instructional design manipulations have primarily been investigated under tightly controlled laboratory conditions. We carried out two experiments, where the first experiment was conducted in a restricted system-paced setting and is therefore in line with the majority of empirical studies in the…

Educational hypertexts usually include graphical overviews, conveying the structure of the text schematically with the aim of fostering comprehension. Despite the claims about their relevance, there is currently no consensus on the impact that hypertext overviews have on the reader's comprehension. In the present paper we have explored how…

The third in a series of reports on the educational applications of computers. Focuses on ERIC materials that can help educators learn more about the graphic capabilities of CRTs. (FL)

A recent survey of 60 commercial computer assisted instruction (CAI) programs found that most of the programmed lessons used few or no graphics to communicate the main points. An Instructional Graphics Checklist was developed to reflect the research findings about the use of pictures in instruction and to serve as an informal evaluation instrument…

This report describes the operation of a computer monitor called MYCROFT, a system which can debug elementary programs for drawing pictures. The basic skills which are fundamental to debugging skill (description, plan, linearity, insertions, global knowledge, and imperative semantics) are examined. These programs are written for LOGO turtles.…

A set of teacher guidelines for use in developing effective computer-assisted instruction lessons enhanced with computer graphics. (JJD)

Describes a presentation of basic quantum mechanics for nonscience majors that relies on a computer-generated graphic display to circumvent the usual mathematical difficulties. It allows a detailed treatment of free-particle motion in a wave picture. (MLH)

Describes a computer application that uses graphics, color, and animation to make the learning of statistical reasoning with uncertainty easier and more fun. Notes that the initial implementation focuses on the Dempster-Shafer model, although the design is a framework that can incorporate other models. Also discusses how the tool may be used to…

Reviews an authoring system for courseware development (Applesoft Basic) consisting of a programed template allowing preparation of instructional units composed of text, questions, and graphics. A higher-priced version includes a game. Geology, oceanography, space science, meteorology, human/plant anatomy, and cells/genetics diagrams are available…

Describes the use of computer-assisted graphical displays in experiments to determine the order and activation energy for a chemical reaction. (MLH)

Describes study conducted to assess the ability of first grade students to interpret and use computer-generated pictures. Differences in physical attributes between computer-generated and traditional picture formats and their effect on children's ability to interpret and process information contained in the pictures are discussed. (six references)…

Describes the derivation of the parameters incorporated into computer programs that are utilized to draw hypocycloids, which are the loci of points traced out by a point on a disk as it rolls against a circle and its interior. Includes information to obtain copies of the programs described. (JJK)
