The widespread availability of computational graphics for personal computers has greatly increased the potential for visual display of research data. The correlation between two variables can be represented graphically by using circles to represent the variance associated with each circle, and by letting the overlap between the circles be…

This report documents a computer-based gaming system for assessing recognition performance (RECOG). The game management system is programmed in a modular manner to: instruct the student on how to play the game, retrieve and display individual images, keep track of how well individuals play and provide them feedback, and link these components by…

Investigates the mathematical behavior of 30 college students in a problem situation that requires them to find the inverse of a given compound element in an environment of LOGO turtle graphics. Results from interviews indicate that, in searching for the inverse, students tend to invert the elements but not the order. (MDH)

Described is a short program for teaching and learning about geometric transformations. The integration of geometry problem solving and BASIC programing is discussed. Applications of computer graphics are illustrated. (CW)
