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)

Presents a prototype of a computerized grammar kit written in PROLOG and designed for children interested in exploring language. PROLOG's advantages for building parsers, generators, translators, and question-answering systems are discussed, and a scenario of a child working on a grammar project using the kit and implementation issues are…

Provides computer programs (for Apple microcomputers) for drawing (in high resolution graphics) a three-leaved rose, concentric circles, circumscribed and inscribed astroids. Sample output and discussions of the mathematics involved in the programs are included. (JN)

Presents an instructional process designed to achieve educational objectives (comprehension, analysis, evaluation, synthesis, and application) in introductory computer programming and applications courses through student projects. The projects involve goals based on these objectives and integrate computational techniques, plotting displays, and…

Discusses print quality, speed, print modes, buffers, and character sets of daisy-wheel and dot-matrix printers; briefly reviews features needed to print graphics and color; and presents a chart listing over 30 typical daisy-wheel and dot-matrix printers for comparison of features and price. (MBR)

By applying a computer-aided drafting system to a range of facilities layouts and plans, a division of Tektronix, Inc., Oregon, is maintaining staffing levels with an added workload. The tool is also being used in other areas of the company for illustration, design, and administration. (MLF)

Described is the use of computer graphics terminals to present diagrams relating to physics concepts. (SL)

Describes computer programs and projects designed to assist the chemical researcher in solving problems on-line. Discusses programs that interpret molecular structures, analyze multivariant data, and generate structural isomers of compounds. (MLH)

This study applies social judgment theory and interactive computer graphics to labor-management negotiations. Self-understanding and understanding of one's counterpart were found generally to be poor. Participants reported gaining new insights and indicated that the use of interactive graphics is feasible and desirable. (Authors)

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)

Computer graphics provides a valuable tool for the representation and a better understanding of structures, both small and large. Accurate and rapid construction, manipulation, and plotting of structures, such as macromolecules as complex as hemoglobin, are performed by a collection of computer programs and a time-sharing computer. (21 references)…

Current plotting techniques offer new ways for decisionmakers to look at data via graphs, pictures, maps, and 3-D models. (Author)

Describes phenomena that can be effectively illustrated using microcomputers, techniques used to create these illustrations, and techniques used for displaying them in regular classrooms and over an instructional television network. Also describes microcomputer features required to apply the techniques, providing comments on the suitability of…

Interactive Simulation Language (ISL) is a highly interactive and graphics-oriented language. ISL use in senior design course and introductory system modeling/system behavior course is discussed (including instructional strategies, self-administered instruction, and problem assignment). A description of ISL (including block library and main menu)…

Describes a computer program which allows students to specify rather arbitrary sets of poles and zeros for the transfer function of a linear system. The computer evaluates/plots the systems impulse and step responses individually and displays them in reduced form along with the pole-zero plot. (JN)
