Digital Libraries for Education: A Progress Report on the National Science Foundation's (NSF) National Science, Technology, Engineering, and Mathematics Education Digital Library (NSDL) Program

摘要

The decade since the introduction of the World Wide Web has witnessed dramatic advances in the underlying communication capabilities of the Internet. These include greater numbers of access points; increased bandwidth of existing and new networks; growth in the deployment of new transmission technologies (e.g. various versions of DSL, cable modems, and in remote areas, satellite providers); and the emergence of wireless technologies, from Wi-Fi to WiMax (see www.wimaxforum.org). Indeed, the ability for the latter technologies to "untether" the user from the Internet is quickly permitting new and in some cases unforeseen uses of the Internet, posing interesting questions and challenges to our assumptions about user behavior and information needs.
