Teacher Julianne Chamberlin's eighth-grade physical science class is as fun as it is informative. For proof, just check her Web site. Chamberlin has adopted educational methods developed by Randy Yerrick, professor and associate dean of educational technology in the University at Buffalo Graduate School of Education. Using examples of effective teaching known as "inquiry learning" as a kind of cyberspace lesson plan, Yerrick has merged proven classroom methods with state-of-the-art technology, including podcasting, movie-making and digital photography.
