Using the WWW as the delivery mechanism for interactive, visualization-based instructional modules

Abstract

Visualization has long been an important pedagogical tool in CS education. The widespread use of the Web and the introduction of Java, with its ability to present interactive animated applets and other types of animation, all provide opportunities to expand the availability of visualization-based teaching and learning tools. In addition, the Web introduces new opportunities not available in traditional settings.

We then discuss a number of different mechanisms that can be used to deliver visualizations over the Web and new ways of managing displays in the Web-based environment. We point out both advantages and disadvantages of using the Web. A look into the future follows. We consider what...
