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 a short computer program written in Logo programing language designed to provide students with new experiences in the study of vectors as they apply to classical physics. Suggestions for introductions, preparation, follow-up activities, and program examples are included. (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)

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)

Describes a series of programs written in Logo that have been used successfully to support young children's programing efforts. These programs remove the mechanical obstacles of typing, spelling, and estimating distances; remove the demands of abstract planning and ordering instruction; and provide a set of programing procedures.
