The graphics teaching tool

To be a "literate" citizen one must increasingly be able to critically evaluate digital visual materials, make decisions using digital visual representations of data and ideas, and use computers to create effective visual communications. To be literate in this sense demands at least a basic understanding of computer graphics principles. Existing curricular resources, however, are chiefly aimed at students studying computer science and related fields. For the majority of students, who do not pursue technical degrees, there is virtually no recognition of the importance of basic graphics principles or even reference to their existence. To address the needs of this audience we have developed a novel interactive Graphics Teaching Tool (GTT). The GTT is a Java-based application (and applet) that offers 2D and 3D graphics in a single environment. It is expressly designed for teaching and uses a mental model-based pedagogical approach not found in commercial graphics software.
