Presents a program written in USCD Pascal that simulates a system routine. Illustrates standard and user defined boolean and string functions and string procedures. Details the processing operations. (CW)

Proposes to modify the procedure proposed by Abelson and diSessa to produce a polygonal path with vertices that lie exactly on an ellipse. Provides a detailed proof. Implements a limiting process to produce the best possible approximation to any ellipse for any given screen resolution. (CW)

Provides an introduction to the mathematics and art of the complex plane. Includes two computer programs written in GW BASIC to facilitate a reader's initial investigation. Identifies additional software resources. Stresses the appeal to future scientists, mathematicians, and artists. (CW)

Provides a method to use superscripts and subscripts on the screen by using graphics screen modes. Gives two methods and provides a listing of a sample BASIC program. (MVL)

Provides abstracts of selected mathematics and science papers presented during the conference. Topics included: (1) problem solving using the computer; (2) controlling the environment through Logo; (3) software and technology in the science curriculum; (4) learning multiplication facts using multiple strategies; and (5) limitations and potential…
