Where other educational technologies like television, the VCR and the stand-alone computer have failed to have much of an impact in public schools, local school networks and the Internet have been succeeding. As of 1997, 89% of America's high schools were connected to a computer network. This paper presents a view of network technology from the perspective of teachers at TechCity High School. Despite massive technical difficulties, little training, and minimal recognition, these teachers are finding new ways to use computer networks in labs and in their classrooms. The teachers are finding that computer networks, compared to older technologies, are versatile and easy to use. Results of this multifaceted, ethnographic study document the impact that school computer networks and Internet access are having on teachers' professional environments and on their teaching methods. Questions for the technology plan blueprint is appended. (Contains 13 references.) (Author/AEF)
