Provides insight into technique for developing 3-dimensional computer graphics for use in artistic expression, design of functional objects, and the development of frame-by-frame computer animated films. Objects defined by intersecting spheres, hardware, software, examples, and illustrations are included. Twenty-four references are cited. (EJS)

Describes initial encounter of a fifth grade student with Logo, a computer program language designed to develop in the user a knowledge of programing, geometry, arithmetic, and problem solving. A brief description of Logo, programing examples, and two references are included. (EJS)

Description of the field of robotics and its possible use in high school computational geometry classes emphasizes motion planning exercises and computer graphics displays. Eleven geometrical problems based on robotics are presented along with the correct solutions and explanations. (LRW)

Discusses author's adaptation of the computer language Logo as an aid in teaching college preservice education students programming, geometry, arithmetic, and problem solving. A description of how Logo works and an example of how "turtle geometry" can be used to help teach geometry concepts are included. Four references are listed. (EJS)
