The Air Force has been plagued with the rising cost of technical training and has increasingly turned to computer-assisted instruction (CAI) for better cost effectiveness. Toward this aim a trial of PLATO IV, a CAI system utilizing a graphic display and centered at the University of Illinois, was initiated at the Chanute and Sheppard training…

Research employed two types of redundancy, each having two levels, at each stage of a programed sequence of non-verbal concept learning tasks. One type involved amount of variation and repetition of exemplars; the other, strength of feedback. A researcher presented tasks to 4th, 5th, and 6th graders, simulating a computer graphic display. The…

Thanks to film, graphic artists can now create over time as well as in space. An essay discusses the influence of cinema on still paintings (e.g., Duchamp's "Nude Descending a Staircase" and the increasing combination of animation and live action in films. New techniques that are available in animation and in special visual effects are explained,…

Today, our environment is created more by television and cinema than by nature. Our view of what human nature is and might be is conditioned by what we see in those media. Films which make use of traditional genres only reinforce traditional views. They do not force us to new ones. But new filmmakers are creating "synaesthetic" cinema, which…

Computer-based instruction (CBI) encompasses the functions of computer administered and managed instruction supplemented by utilities and interfaces. The course author's function in computer-administered instruction (CAI) is to construct the lesson for input in one of three formats: (1) batch entry used by those with knowledge of programing…

This article presents predictive validity data for on-job performance for a set of computerized Graphic and Interactive Processing (GRIP) tests in conjunction with data for both experimental paper-and-pencil and operational tests. Validity coefficients for job element and global criteria are reported for four different jobs. (See also EJ 161 400).…

Discusses the types of problems that arise when text is presented in electronic form: (1) surface design, which involves typography, layout, graphics and illustrations, and the quality of language; and (2) interface design, which is manifested on the levels of immediate surface of the text, internal structure, and external structure. (SKC)

Presents description of local-area network of personal computers installed in the Broadcast News Laboratory at the University of Texas at Austin to help produce and teach broadcast news. Highlights include development and design of the system, software and hardware considerations, and the use of tutorials for writing and technical concepts. (LRW)

Describes the computer literacy requirement of the Professional Teacher Preparation Program at Arizona State University. Highlights include microcomputer-based software used; word processing; database skills; spreadsheet tasks; teacher utilities for producing graphic materials, generating tests and practice exercises, and keeping records; and…

It is argued that microcomputer technology has evolved to the stage that it should be routinely used by mathematics students at all levels. It is shown how the use of microcomputers can change the way problems are solved. Computer-generated graphics are highlighted. (PK)

The article considers the problem of how to plot on the computer screen a circle with center (A,B) and radius R. Several different procedures are discussed and compared. (PK)

Outlines three lessons designed to increase students' involvement in social studies classes, excerpted from the author's book, COMPUTERS, CURRICULUM, AND WHOLE-CLASS INSTRUCTION. Student surveys, supported by database and/or graphing software, are used to study immigration, banking and technology, and interpreting graphs and bias in information.…

Reviews three softwre packages: "Molecular Graphics on the Apple Microcomputer, Enhanced Version 2.0"; "Molecular Graphics on the IBM PC Microcomputer"; and "Molecular Animator, IBM PC Version." Packages are rated based on ease of use, subject matter content, pedagogic value, and student reaction. (CW)

Describes study of fourth and fifth grade students which explained the effect of graphics on student motivation in a microcomputer-based spelling drill program. The role of feedback in instruction is discussed, the impact of graphics on computer software is described, and results are analyzed. (4 references) (LRW)

Proposes to modify the procedure proposed by Abelson and diSessa to produce a polygonal path with vertices that lie exactly on an ellipse. Provides a detailed proof. Implements a limiting process to produce the best possible approximation to any ellipse for any given screen resolution. (CW)
