A computer program, making use of interactive computer graphics, has been developed to help students become fluent in the mathematical procedures needed to understand concepts of addition of waves. Background theory, use of the program, and technical and educational features of the program (written in Fortran) are discussed. (Author/JN)

Describes and compares five different uses of computers in physics education: tutorial, demonstrations, modelling toolkit, laboratory aid, and student as programer. Provides examples of computer uses and offers perspectives on developing further programs. (ML)
