Relates experiences of an elementary school reading teacher and a group of fifth- and sixth-grade students in exploring the computer programing language Logo. Use of a tree-like figure as an illustration for the concept of recursion is described. Programing commands and graphic illustrations are included. (EJS)

Presents a programing subroutine which will create a graphical plot that occupies any number of columns specified by user and will run with versions of BASIC programming language. Illustrations of the subroutine's ability to operate successfully for three possibilities (negative values, positive values, and both positive and negative values) are…

Comparison of dot matrix impact printers details price, matrix density, speed, print sizes, feed width, interface connectors, and true descender characteristics. Dot matrix versus preformed characters, maintenance and repair, installing printers at microcomputer workstations, value comparisons, and descriptions of specific printers are…

Provides a brief discussion of the graphics capabilities of microcomputers and describes specific graphics hardware and software that are available for the more popular microcomputers. The names and addresses of the producer/distributor and prices are given for each item. (CHC)

Describes modifications made to expand the capabilities of a display unit (Lear Siegler ADM-3A) to include medium resolution graphics. The modifying circuitry is detailed along with software subroutined written in Z-80 machine language for controlling the video display. (JN)

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 ZGRASS, a programing language designed for graphics production, especially for applications in education and training, and provides guidelines for people looking into a new computer graphics system. (CHC)

Routines developed for an ongoing course in research methods and statistics provides examples of the custom instructional applications that can be created using extended BASIC and a light pen, including title and transition displays, progressive disclosure, animation, overlays, and simulations. Strengths of this technique are reviewed. (MBR)

Presents the options and limitations available in microcomputer-based graphic systems. Factors that must be considered when selecting a system--resolution, color, video-compatibility, and cost--and the relationship between these factors are discussed. (MBR)

The computer packages of PLOTALL, SYMAP, SURFACE II, QUSMO, QUSMO2, QUCRS, and QUTAB are commercially available plotting programs that provide aids for visualizing spatial distributed data and concepts. The incremental drum and line printer plots communicate often vast and difficult-to-interpret tabular data with or without geographic coordinates.…

Describes the design of a microcomputer-based system at the University of Ottawa which provides teachers with the capabilities of computerized slides and transparencies. The slides are texts created with word processors which are presented to the class via a large screen video projector, and software provides regular overhead projector functions.…

One in a series of 10 promotional publications on videotex, this document describes both videotex and teletext and illustrates with actual examples how educators are using these new tools. Topics discussed include the educational roles permitted by the standardization of videotex and teletext; characteristics of the North American Presentation…

A guide to computer peripherals--additional hardware that can expand the educational uses of computers--is given. Tips are furnished on selection and possible use of computer printers; modulator/demodulators (modems); graphics tablets; plotters, speech synthesizers, and robots. (PP)

Advantages of using the microcomputer as an interactive electronic blackboard are discussed, and programs and programming techniques are described to illustrate the construction, design, storage, and modification of colorful and animated graphic displays. The methods described are based on use of an Atari 800 microcomputer but could be used on…

Describes Graphics Project for Foreign Language Learning at the University of Pennsylvania, which has developed ways of displaying foreign scripts on microcomputers. Character design on computer screens is explained; software for graphics, printing, and language instruction is discussed; and a text editor is described that corrects optically…
