A manual describes the use of graphic commands in student-computer dialogues. How to construct axes, windows, boxes and various other computer displays is explained, in particular reference to the ARDS 100 and TEKTRONIX 4002 and 4010 computer terminals. Concrete examples of displays are included. The appendix contains an explanation of the use of…

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.…

This paper presents a study on the effects of various data compression methods from the viewpoint of central computer to terminal communications on a large graphics oriented timesharing system, PLATO IV. The desired goal is to increase terminal display speed without significant increase in the transmission error rates. While the major emphasis in…

The TUTOR logic-building language to be used with the PLATO (Programmed Logic for Automated Teaching Operations) system is explained in this manual. TUTOR is designed to transcend the difficulties of FORTRAN for a computer-based educational system utilizing graphical screen displays. The language consists of about seventy words or…

Discusses ways of providing graphic support in computer-based learning environments, outlines a simple case study involving a situation requiring graphic support, and describes several author language/systems that contain facilities to support the use of graphics. (MBR)

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…

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…

A graphics terminal designed for use as a remote computer input/output terminal is described. Although the terminal is intended for use in teaching applications, it has several features which make it useful in many other computer terminal applications. These features include: a 10-inch square plasma display panel, permanent storage of information…

Identifies human factor issues involved in the student-computer interface in computer assisted instruction and makes specific recommendations for screen design. Factors considered include simplicity, spaciousness, relevance, standardization, changing display screen contents, color coding, shape and size coding, and brightness coding. (Author/LRW)

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)

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 report describes a graphics terminal designed as a remote computer input-out terminal for unsophisticated users. The first chapter focuses upon the terminal's plasma display panel, its self-contained character and line generators, and its ability to communicate over low grade telephone lines. Chapter 2 concentrates upon operating modes,…

In an effort to gain an overview of the application of computer technology in education and training, to identify areas requiring additional research, and to identify potential application areas for use in technical training, field visits were made to representative military and civilian institutions which are using the computer in instructional…

New, more versatile and inexpensive terminals will make computer graphics more feasible in science instruction than before. This paper describes the use of graphics in physics teaching at the University of California at Irvine. Commands and software are detailed in established programs, which include a lunar landing simulation and a program which…

This paper gives a technical description of various computer graphics programs developed on the Sigma 7 computer. Terminals used are the Adage 100 and the Tektronix 4002-4010. Commands are Metasymbol procedures which access Metasymbol library subroutines; programs can also be coupled with FORTRAN programs. Available, inexpensive graphic terminals…
