Most technological innovations are slow to find their way into the classroom.
Video was around for several decades before educators began to seriously explore its use, and other forms of mass communication have never found a niche in the academic environment. This history contrasts sharply with the adoption of new technologies in manufacturing and research - technologies that, more often than not, originate in university laboratories. In the 1990s, however, we've seen the advent of the Internet and with it the World Wide Web of networked computers. What began as a National Science Foundation sponsored effort to link major university computer systems into a global communications network, became overnight both a major resource and a major challenge for teachers at all levels. Like young Hercules confronted with a choice between Virtue and Pleasure, teachers today face two opposing realities when they look at the new technology.
