Few methods have been tried and used to graphically represent more than two variables. This poster session showed a new method for representing three continuous variables on a single scatterplot using the THREEDE computer program. Two variables are represented as a normal bivariate distribution. The third variable is represented by a symbol, e.g.…

This report documents a computer-based gaming system for assessing recognition performance (RECOG). The game management system is programmed in a modular manner to: instruct the student on how to play the game, retrieve and display individual images, keep track of how well individuals play and provide them feedback, and link these components by…

This discussion of factors involved in the presentation of text, numeric data, and/or visuals using video display devices describes in some detail the following types of presentation: (1) visual displays, with attention to additive color combination; measurements, including luminance, radiance, brightness, and lightness; and standards, with…

Presents a prototype of a computerized grammar kit written in PROLOG and designed for children interested in exploring language. PROLOG's advantages for building parsers, generators, translators, and question-answering systems are discussed, and a scenario of a child working on a grammar project using the kit and implementation issues are…

Eleven basic types of visually displayed information that can be, and should be, rendered accessible to the visually impaired user are discussed. Speech, braille, and tactile technology are addressed as well as the innovative technique of "haptic-tactic" display combining a raised dynamic image of the screen's page with speech. (Author/DB)

This study focused on the cognitive conflicts experienced by young children in using software programs that provided them with tools to create and/or combine individual graphic elements into larger structures. Six 5-year-old children, none with prior computer experience, were observed using three programs--Kids at Work, Picture Perfect, and…

Pointing out that interactive video (IAV) represents a synthesis of four primary technologies--computers, television, visual design, and instructional design--this paper discusses the what, why, and how of IAV visuals. The features and relevant aspects of each technology are briefly discussed, as well as the impact of each of these technologies…

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…

Computer based instruction (CBI) is composed of individual frames viewed one at a time. Compared to a typical textbook, CBI restricts the adult learner's capacity to access information from different parts of the lesson and to view complex presentations. Designers of CBI must compensate for these limitations by making a concerted effort to…

Identifies human factor issues involved in the student-computer interface in computer assisted instruction and makes specific recommendations for screen design. Factors considered include simplicity, spaciousness, relevance, standardization, changing display screen contents, color coding, shape and size coding, and brightness coding. (Author/LRW)

Discusses use of computer simulation as an archeological tool for research and teaching involving the remains of prehistoric game animals to aid in understanding effects of various strategies of prehistoric hunters on populations of game animals. A simulation involving possible vicuna hunting strategies is described. (MBR)

A 10-week project conducted with 12 gifted 4th and 5th grade students (10 boys and 2 girls) examined the effectiveness of the Logo computer programming language as a tool for helping students understand some basic principles of physics. Three assumptions were tested: (1) motivated elementary school students can learn both turtle graphics and word…

Focuses on use of computer-drawn faces to explore visualization in learning and for presenting multivariate data. Prior and new research are reviewed and future applications are discussed. "Autocorrelation-face," a graphics representation created from mathematical analysis of voice input, and its potential as a learning aid for the deaf are…

Describes the development of INTERACT, a videotext system in which information and graphics were designed using a systematic multistage formative approach. The assessment of information needs is explained, and results of an evaluation completed after five weeks of operation in the student center at Syracuse University are discussed. (Author/LRW)

Discussed are three examples of computer graphics including biomorphs, Truchet tilings, and fractal popcorn. The graphics are shown and the basic algorithm using multiple iteration of a particular function or mathematical operation is described. An illustration of a snail shell created by computer graphics is presented. (YP)
