Discusses computer instruction in light of Bruner's theory of three forms of representation (action, icons, and symbols). Examines how studies regarding Paivio's dual-coding theory and studies focusing on procedural knowledge support Bruner's theory. Provides specific examples for instruction in three categories: demonstrations, pictures and…

Discussion of information visualization and computer graphics focuses on a study that contrasted performance in three dimensional (3D) and two dimensional zooming interactively (2.5D) virtual worlds for people with differing levels of spatial and structure learning ability. Suggests implications of individual differences for the usability and…

This article discusses procedures that have been developed to empower students with disabilities to take responsibility for graphing data reflecting their own academic performance. It discusses training methods for teaching students self-graphing and the benefits of self-monitoring. Examples are provided of different types of computer graphs.…

Examines the effects of pictures (screen captures and input devices) on documentation for older novice computer users (aged 26 to 69 years). Argues that screen captures help reduce memory load and support visual scanning for older users. Finds no support for the prediction that the presence of pictures would make some manuals more effective than…

Presents a conceptual overview of online information systems, emphasizing the distinction between hypertext (associative) and more traditional (search) models of information management. Five commercially available hypertext systems are reviewed, hypertext design issues are discussed, and the application of structured writing techniques to…

Briefly describes some available database design tools and provides a detailed description and evaluation of the ER-Design Package, a sophisticated and comprehensive tool available on microcomputer. Some of the ER-Design functions evaluated include the main design module, diagram generation, conversion to relational schema, normalization of files,…

Discusses the emerging need of users for bulk numerical, graphic, and textual information, and describes a range of tools available for information reduction and restructuring, and the conversion of data into information. Some of the tools described include graphics databases, hypertext applications, and search systems that utilize relationships,…

Describes a computer network developed at the School of Engineering at Rice University which links users to a supporting mainframe and other major computing facilities, and creates an electronic studio for students. Topics discussed include network planning, design, and maintenance; software and courseware used; and implications for other academic…

Predicts that online searching in the 1990s will be characterized by end users discovering faster and easier ways to access information. Predicted trends that are discussed include databases designed for end users, pricing innovations, increased use of CD-ROM products, improved computer graphics, and the expansion of database products into the…

Reviews the newest addition to Pelican's Creative Writing Series of instructional software, which uses the comic book format to provide a unique writing environment for satire, symbolism, sequencing, and combining text and graphics to communicate ideas. (SR)

Describes the uses of the Amiga computer, a "digital canvas" that creates computer-generated art and graphic displays. Examines how computer-graphics programs can be used in a course that is totally interactive with the computer. (MM)

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)

Describes the development of the microcomputer-based educational software, DNAzoom, which was designed to introduce undergraduates in molecular biology to computer analysis of DNA protein sequences. Highlights include graphical presentation of data, the functional use of color, a menu-oriented interface, and students' evaluations of the software.…

Discusses the impact of computers on the art community. Topics discussed include merging technology with art, full color graphics on personal computers, commercial painting software, graphic design, visual flexibility, programing, the computer as an art medium unto itself, cost factors, and benefits to art instructors. (LRW)

Suggests some ways to enhance the user-friendliness of many Macintosh (personal computer) foreign language character fonts with the aid of three commercial programs: MacKeymeleon; FONTastic Plus; and Tempo. (Author/CB)
