Described is an inexpensive apparatus, consisting of a microcomputer, a magnetostrictive digitizing tablet, and a teletype terminal, that accurately and quickly measures positions, lengths, and areas. Particular emphasis is given to interfacing, software, and to some applications in education and research of this minimum configuration system.…

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)

Computer video games are an emerging instructional medium offering strong degrees of cognitive efficiencies for experiential learning, team building, and greater understanding of abstract concepts. As with other new media adopted for use by instructional technologists for pedagogical purposes, barriers to classroom implementation have manifested…

A new system of computer-assisted instruction (CAI), developed at Whitworth College, is proposed called PIRATS. It is said to have the following advantages: (1) it uses an author language; (2) it provides facility for branching and responses to unpredicted answers; (3) lesson text is prepared off-line; (4) pictures can be used to accompany the…

Arguing that a well designed graphical display can function as a memory store, this article suggests three principles for the design and use of computer graphics: parsimony, accessibility, and reflection. It is suggested that "progressive graphics" are particularly suited to computer implementation. (Author/MBR)

Both general and specific guidelines are proposed for the use of different types of graphics under specified conditions which would be relevant to various instructional applications of the videodisc. The general guidelines cut across several conditional variables--e.g., color, realism, motion--while the specific guidelines are directly related to…

Discusses the use of the computer animation technique to travel through space and time and watch models of astronomical systems in motion. Included is a list of eight computer-generated demonstration films entitled Explorations in Space and Time.'' (CC)

Discusses the impact of the presentation of data on the educational effectiveness of computer assisted learning systems, describes some of the existing systems for controlling the display of instructional data on CRTs, and outlines a project undertaken at the University of Western Ontario to exploit the capabilities of microcomputer color…

Discussion and examples of the use of computer graphics in science and calculus instruction are provided. (SD)

A 35mm random access slide projector operated in conjunction with a computer terminal was adapted to meet the need for a more rapid and complex graphic display mechanism than is currently available with teletypewriter terminals. The model projector can be operated manually to provide for a maintenance checkout of the electromechanical system.…

Two different uses of interactive graphics in computer-assisted instruction are described. Interactive graphics may be used as substitutes for physical devices and operations. An example is simulation of operating on man/machine interfaces, substituting interactive graphics for controls, indicators, and indications. Interactive graphics may also…

A study was made of the extent and ways different types of educational software allow young children to manipulate their own actions and, more specifically, to engage in reversible activity. Part 1 of the study consisted of an analysis of the types of reversible actions two kindergarten children engaged in and the actions they wanted to engage in…

This manual describes the CALM TV graphics interface, a low-cost means of producing quality graphics on an ordinary TV. The system permits the output of data in graphic as well as alphanumeric form and the input of data from the face of the TV using a light pen. The integrated circuits required in the interface can be obtained from standard…

This report describes the remote computer terminal designed for student use in the PLATO IV computer-assisted instruction system. The terminal features a plasma display panel, self-contained character and line generators, and the ability to communicate over voice grade telephone circuits. Operating modes and control characters are described in…
