This is a report of a program aimed at the demonstration, tests, and evaluation of the educational and economic effectiveness of PLATO IV computer-based education as implemented in several geographically dispersed military training sites. It also describes a technical program aimed at increasing the cost effectiveness of the PLATO system. During…

This manual describes a text processing system developed to teach relatively inexperienced users how to enter and edit textual materials. Also provided is information on storage and system maintenance for the system manager. It contains nine sections and two appendices with sections two through nine arranged in a sequence which corresponds closely…

This paper outlines the development of an activity that uses the computer's unique capabilities to provide students with a meaningful and highly motivating experience with the graphing of equations. The basic design of the game calls for the computer to display a coordinate grid on which it graphs any equations that are typed in by the student.…

This discussion of the advantages and limitations of raster graphics systems points out that until recently, most computer graphics systems have been oriented toward the display of line drawings, continually refreshing the screen from a display list of vectors. Developments such as plasma panel displays and rapidly declining memory prices have now…

This document describes a system that has been developed to use a digital computer graphics terminal for interactive analysis of piecewise continuous systems of nonlinear differential equations. This program allows even a novice user to freely investigate the behavior of control systems and solutions of differential equations by changing initial…

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 study compares the effectiveness of three types of computer graphics display for computer-assisted instruction in (1) low level (boxed alphanumerics and schematics), (2) medium level (line drawings), and (3) high level (line drawings plus animations). Three groups of 30 enlisted personnel at the Engineering School and the Defense Mapping…

This paper describes the development of the hardware-software configuration required for a computerized digitizer-graphics system for encoding locational information at the University of Iowa's Department of Geography and Institute of Urban and Regional Research. Topics covered include system requirements, data structure, hardware configurations,…

With increasingly large quantities of management-oriented information being produced for decision-making, administrators are finding that they have insufficient time to adequately review and digest its meaning. This paper discusses the development of a computerized graphics system that will permit nearly all types of management information to be…

Using PLATO, a computer-assisted instruction system, a test was conducted to see if students respond most favorably to an instructional package that included no graphic display, still graphic display, or animated graphic display. Forty-five students at the Naval Training Center, San Diego, were the subjects. With the learning of the sine-ratio…

Many of the costs of design, construction, and building operation derive from the reliance on drawings as the description of record of the building. As a replacement, this paper outlines the design of a computer system useful for storing and manipulating design information at a detail allowing design, construction, and operational analysis. A…

The development and capabilities of an interactive preprocessor program with graphics for an existing three-dimensional finite element code is presented. This preprocessor program, EDGAP3D, is designed to be used in conjunction with the Texas Three Dimensional Grain Analysis Program (TXCAP3D). The code presented in this research is capable of the…

A computer program for the simulation of complex continuous process in real-time in an interactive mode is described. The program is user oriented, flexible, and provides both numerical and graphic output. The program has been used in classroom teaching and computer aided design. Typical input and output are illustrated for a sample problem to…
