Since the early 1990s and birth of the World Wide Web, instructional experimentation with Internet integration has been undertaken. While efforts are varied, usage of the Internet can be grouped into three general categories: communication supplements, course management aids, and course content supplements. Communication supplements are those that enhance the interaction between instructor and students. Course management aids provide organization and computerized mechanisms for both delivery and collection of course material and also serve as interactive study guides. Course content supplements add outside readings and materials to contribute to and enhance textbook subject matter. From a cross-disciplinary perspective, this paper highlights how the Internet can be used to increase learning and the interest to learn, and reduce the costs of course management, research, locating educational information, and communication. Experiences in business, economics, and engineering courses are given and generalized to other disciplines. (AEF)
