This paper reviews the literature pertinent to learning with graphics. The dual coding theory provides explanation about how graphics are stored and precessed in semantic memory. The level of processing theory suggests how graphics can be employed in learning to encourage deeper processing. In addition to dual coding theory and level of processing…

Over the past few years, video technology has been used to assist film directors after they have shot a scene, to control costs, and to create special effects, especially computer assisted graphics. At present, a computer based editing system called "Film 5" combines computer technology and video tape with film to save as much as 50% of…

The differences between the media of books and computers lies partly in the way in which information is displayed, rather than in the content of the information itself. The term "legibility" denotes how specific physical characteristics of a display affect visual fatigue, reading speed, and ultimately comprehension. Some of these…

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…

Telewriting, televideo, and facsimile systems are new forms of teleconferencing which can transmit a variety of graphic and pictorial information on voice-grade telephone lines. All of the equipment employs solid-state circuitry to enhance performance and to exploit the limitations of a narrowband channel. Telewriters range from simple…

The first of two articles discusses the current status of desktop publishing, including some of its benefits and limitations. The second article compares and critiques both hardware and software currently available for the Macintosh and for MS-DOS microcomputers. A glossary of typographic terms is included. (CLB)

Describes various new computer graphic display capabilities (e.g., animation of graphics and text, direct manipulation of on-screen graphics elements) and reviews relevant literature that could assist in determining how these new capabilities could be used effectively in computer assisted instruction applications. (Author/MBR)

Discusses the potential that definitions of visual and television literacy offer for understanding computer literacy. Three areas of visual literacy research covered include visual communication and languaging; visual processing and thinking; and general definitions of visual literacy. Anderson's television literacy objectives are also reviewed.…

Reviews the effectiveness of animation in enhancing textual information for instructional purposes and identifies factors that determine effectiveness. Outlines methodological problems in the research and summarizes design criteria for multimedia instructional products. Contains 78 references. (PEN)

In the last 10 years, an approach to electronic distance education called audiographic computerized telelearning using standard telephone lines has come to the fore. Telelearning is a cost-effective system which optimizes existing computer facilities and creates a teaching-learning environment that is interactive, efficient, and adaptable to a…

This history and state-of-the-art review of computer graphics describes computer graphics programs and proposed programs at Sheridan College (Canada), the Rhode Island School of Design, the University of Oregon, Northern Illinois University, and Ohio State University. These programs are discussed in terms of their philosophy, curriculum, student…

Although the use of animated visuals is both common and popular among computer based instruction (CBI) designers, the theoretical and empirical foundation for their use have not been firmly established. Animated visuals represent a subset of instructional visuals, not a distinctive set. For this reason, general conclusions from research on static…

This investigation of the encoding features of graphs begins with a description of a cognitive framework which allows designers to factor into the process of designing displays how people interpret the information found and what display properties are responsible for this interpretation. The framework also provides a performance measure for use in…

Some of the major trends in the merging of videotex and personal computer technology are outlined in this promotional brochure, one of 10 in a series on videotex, a system which uses standard transmission links to transmit information in text and graphics to a television set or computer monitor. Topics addressed include the NAPLPS standard (North…

Describes current developments in microcomputer technology, including CD-ROM, the 80386 microprocessor, and the graphic user interface. It is argued that, as the information handling capacity of microcomputers increases, the microcomputer industry will increasingly market information to end users, and the library will be challenged to provide the…
