EDGE: The Educational Geometry Environment
by Thomas F. Banchoff and Richard Schwartz

Although differential geometry courses at Brown University have been using computer-generated media such as color films, slides, and video for a long time, recently computers have taken an even larger role in facilitating the understanding of geometry.

Over the past year, students have been participating in interactive computer labs that allow them to investigate curves and surfaces with the aid of three-dimensional computer graphics. This paper is aimed at reporting on these experiences.
