Relates experiences of an elementary school reading teacher and a group of fifth- and sixth-grade students in exploring the computer programing language Logo. Use of a tree-like figure as an illustration for the concept of recursion is described. Programing commands and graphic illustrations are included. (EJS)

Presents a programing subroutine which will create a graphical plot that occupies any number of columns specified by user and will run with versions of BASIC programming language. Illustrations of the subroutine's ability to operate successfully for three possibilities (negative values, positive values, and both positive and negative values) are…

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)

Reports on the development and current status of data projection panels, which are liquid crystal display units for projecting computer images onto a large screen with the aid of an overhead projector. Information for various companies' models are listed, including compatibility with computers, color or mono display, software, and price. (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)
