This issue of "CQ Researcher" examines the theme of computer networking in the classroom and discusses uses past and present. It begins with an essay by Christopher Conte that discusses: "Does computer networking really enhance learning? Are teachers adequately prepared to take advantage of computer networking? Will computer networking promote equality or widen the gap between poor and affluent Americans?" The "Background" section looks at barriers to use, the limited early role of computer assisted instruction, and the present, more advanced uses of computers. The "Current Situation" section contains brief articles on high costs and federal initiatives associated with computer networking. The "Outlook" section considers technology and educational reform. The "Sidebars and Graphics" segments include: (1) "Sharing Computers," a United States map with shadings that indicate ratios of students per computer; (2) "How an Imaginative California School District Takes Students Where Textbooks Can't Go"; (3) a "Technology in Schools" bar graph; (4) "Field Trips of the Future"; (5) a "Chronology" of key networking events since 1962; (6) "Networking Resources on the Internet Range from the Esoteric to the Practical"; and (7) a debate over whether computer networking improves instruction. Two annotated bibliographies, with a total of 39 recommended sources, are appended. (BEW)
