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.…

This Computer Graphics Laboratory houses an IBM 1130 computer, U.C.C. plotter, printer, card reader, two key punch machines, and seminar-type classroom furniture. A "General Drafting Graphics System" (GDGS) is used, based on repetitive use of basic coordinate and plot generating commands. The system is used by 12 institutions of higher education…

Engineering design is a complex cognitive skill differing from possession of knowledge in tactical use of knowledge to achieve goals under constraints. An operational definition of a design must satisfy a set of constraints and objectives. Several published theories about the design process in terms of the criteria developed leads to the…

Graphic displays of elliptic, parabolic, and hyperbolic surfaces can be generated by computers. (SD)

Presents a justification of the belief that science and art can be successfully combined. The computer's merits are viewed as a potential modelbuilder for the formalization of aesthetic concepts. The rest of the paper details recent and current research on such uses of the machine. (VT)

Describes the components, costs, and capabilities of several desktop publishing systems, and examines their possible impact on work patterns within organizations. The text and graphics of the article were created using various microcomputer software packages. (CLB)

Explores computer uses in art education, addressing the apprehension with which many educators view such technology. Discusses the graphics capabilities and user-friendliness of computers such as the Macintosh, Amiga, and Atari ST. States that computer versatility, simplicity, and graphic capabilities contribute significantly to art education and…

Comparison of three microcomputer statistical packages, SPSS, SAS, and BMDP, focuses on ease of use, ease of learning, documentation, accuracy, similarity to the mainframe version, and speed. The results of eight statistical multivariate analyses used to evaluate their performance are given. (LRW)

This paper investigated three kinds of changes that could occur when a child learns to program in Logo. Novice programmers from fourth grade classes were given three sessions of Logo instruction. Results provided some preliminary evidence that productive learning of a programming language involves a chain of cognitive changes. (Author/LMO)

The effects of realism on child and adult memory for computergraphics were examined. Recognition of images showed an unusual pattern of decline over time with the initial advantage for realistic and abstract computergraphics disappearing at a week's delay, while recognition for linear image was superior to that of realistic and abstract.…

Sophisticated simulations using computer graphics can lead to students deducing virtually all conditions of the Central Limit Theorem. Eight graphs illustrate the discussion. (MNS)

Five guidelines for enhancing the value of a computer graphics program are described and illustrated. Using a well-structured program, correct scaling, normalized device coordinates, word coordinates, and illusions are discussed. (MNS)

Reviews relevant features for interactive video images of the four primary technologies that merge to intertwine themselves in interactive video (computers, television, instructional design, visual design); outlines critical structural elements of interactive video; and presents guidelines for creating interactive video images. (MBR)

Computer graphics are used to display the sum of the first few terms of the series solution for the problem of the vibrating string frequently discussed in introductory courses on differential equations. (MNS)

Describes Ovation, an integrated software system with a common command environment of 26 English words which provides access to all of the system's capabilities and handles spreadsheet analysis, information management, word processing, graphics, and communications in the same workspace. Capabilities of Ovation's applications and features…
