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…

Presents six computer-oriented classroom activities. They include: surveying a house for products using microprocessors, writing a program to display a flag, experimenting with LOGO's graphics capabilities, writing stories on the computer, using FOR/NEXT commands to create a blinking object, and teaching the Milton Bradley Big Trak to play…

Describes an interactive graphics package which illustrates the phase behavior of binary mixtures. The package has been successfully used with graduate and undergraduate students in the chemical engineering curriculum at Cornell University. Features contributing to this success are noted. (JN)

Discusses the works of Darcy Gerbarg, Ruth Leavitt, David Em, Duane Palyka, and Harold Cohen, visual artists who work with computers to create art works by relying on standard hardware/software tools, using custom tools created for nonartistic tasks, manipulating images at the programing level, and programing creativity into computers themselves.…

B. F. Skinner provides advice for educators on several issues related to computer-assisted instruction (CAI). Some pitfalls of programed instruction in the 1960s which CAI may also face today, aversive control, courseware design, and use of computer graphics are among the areas explored. (JN)

Description of the Macintosh personal, educational, and business computer produced by Apple covers cost; physical characteristics including display devices, circuit boards, and built-in features; company-produced software; third-party produced software; memory and storage capacity; word-processing features; and graphics capabilities. (MBR)

A computer program which allows the solution of a Monte Carlo simulation (probabilistic sensitivity analysis) has been developed for the Vic-20 microcomputer. Theory of Monte Carlo simulation, program capabilities and operation, and sample calculations are discussed. Student comments on the program are included. (JN)

Discusses properties of epicycloids. (The easiest way to picture them is to think of a piece of radioactive bubble gum attached to a wheel which is rolling around the outside of a larger wheel.) Includes a computer program (TRS-80 color computer) that will graph any epicycloid with integer values for the radii. (JN)

Discusses the design and operation of a microcomputer system which obtains and displays an individual's electrocardiogram (EKG). The EKG information, in digital form, can be stored on a floppy disk and transmitted over telephone lines by use of a modem. (JN)
