Describes the database, calculations, and various display modes of a computer subroutine that calculates the chemical score (or index of degree of balance) of essential amino acids in a protein and presents displays useful in illustrating concepts of protein complementarity. (DC)

Describes and evaluates the basic hardware, peripheral devices, system software, graphics capabilities, operations, and other features of the low-cost Commodore VIC-20 color microcomputer system. Included are three simultaneous musical tones plus one noise generator. (JL)

Discusses the application of the PLATO IV computer-based educational system to a one-semester basic drawing course for freshman architecture, landscape architecture, and interior design students and relates student reactions to the experience. (RAO)

Presents specific guidelines for designing instructional programs that will be delivered on microcomputers so that these programs will use the capacity of the microcomputer system in a way that will develop in learners a range of cognitive skills and help learners to evolve useful learning strategies. (Author)

The application of Bezier polynomials in computer graphics to generate curves and surfaces is presented. The use of these curves to aid in the design of automobiles is featured, and a BASIC program designed to draw a simple caricature is included. (MP)

Where large amounts of media support are required for teaching and other needs, the use of new computer-generated graphics may be an economical solution. (Author/MK)

At the South Burlington (Vermont) High School Imaging Lab, students are learning to manipulate the animation technology that NASA uses to design rockets, Hollywood uses to make movies, and architects use to design buildings. Assisted by grants, an English teacher parlayed a single unused computer into a nationally recognized program that helps…

Proposes that a semiotic approach can be used as a supplementary method in assessing the denotations and connotations of the signs and their relationships in computer learning environments. Utilizes the semiotic framework to study visual images, especially how multiple, interactive, and manipulative statistical representations affect the…

Notes that new literacies use computer graphics to tell a story, demonstrate a theory, or support a definition. Offers a functionality framework for assessing the value of computer graphics for early literacy learning. Provides ideas for determining the value of CD-ROM software and websites. Concludes that graphics that give text meaning or…

Discusses ways in which sentences may be represented in a condensed form in graphic displays of a sentence dependency structure. A prototype of a text structure management system, TEXNET, is described; a quantitative evaluation of automatic abbreviation schemes is presented; full-text compression is discussed; and additional research is suggested.…

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)

Examines virtual reality (VR), and discusses the dilemma of defining VR, the limitations of the current technology, and the implications of VR for education. Highlights include a VR experience; human factors and the interface; and altered reality versus VR. (Author/AEF)

Discussion of human-computer interfaces focuses on the use of graphical and direct manipulation approaches to improve the user interface. Topics discussed include information seeking; computerized search capabilities, including full-text string searches, index searches, and hypertext; Boolean expressions; dynamic or direct manipulation queries;…

Provides recommendations for designing computer screens that will have positive effects on readability and learning. Topics discussed include the use of capital versus lower case letters; interlinear space; line length; and strategies that aid recall, including the use of chunks and margins, and the location of information in relation to graphics.…

Describes Photo CD, a procedure developed by Eastman Kodak for storing high-resolution 35mm film images on compact discs, and explains Macintosh microcomputer-based hardware and software that can be used with it. Software for viewing as well as editing and altering images is described, and future products are discussed. (four references) (LRW)
