Abstract

The World Wide Web began in 1990 as a text-based hyper-linked document distribution system for Physicists. Its first use was the electronic transcription of gigabytes of data, textbooks, and faculty notepads. Its initial impact on teaching pedagogy was minimal. In fairness to the World Wide Web, it required heroic efforts to move beyond text and images until fairly recently. But that has changed. It is now possible to author curricula that include interactivity, database access, and mathematical models using off-the-shelf tools. These tools enable educators to design web-based activities that directly influence how students approach a problem. Although interactivity can certainly be accomplished using very sophisticated programs such as Interactive Physics or possibly even QuickTime movies, Java applets are often smaller and can interact with the user via a scripting language. Scripting changes the behavior of an applet and allows it to be used for many different types of questions. This talk will discuss the pedagogic implications and effectiveness of small scriptable Java applets, i.e., Physlets, developed at Davidson College. Interactive pre-labs, homework, tests and Just-In-Time problems will be shown as examples.
