Online learning has attracted a large number of participants and is increasingly becoming very popular. However, the completion rates for online learning are notoriously low. Further, unlike traditional education systems, teachers, if any, are unable to comprehensively evaluate the learning gain of each student through the online learning…

Information seeking is one of the most popular online activities for young people and can provide an additional information channel, which may enhance learning. In this study, we propose and test a model that adds to the existing literature by examining the ways in which parents, schools, and friends (what we call networks of support) effect young…

This paper proposes a theoretical framework as a foundation for building online communities of practice when a suite of social networking applications referred to as collective intelligence tools are utilized to develop a product or solutions to a problem. Drawing on recent developments in Web 2.0 tools, research on communities of practice and…

Online services (OLS) provide billions of Internet users with a variety of opportunities to exchange goods, share information, and develop or maintain relationships. Popular examples of OLS web sites include eBay.com, Amazon.com, Dell.com, Craigslist.com, MSN.com, Yahoo.com, LinkedIn.com, Zillow.com, Facebook.com, Wikipedia.com, and Twitter.com.…

The inherent opportunities for communication, collaboration and experiential learning in an online and global network create the impetus for the new network paradigm in higher education. A strategic knowledge network in education was designed and developed to build "Mode 2" knowledge capabilities; create new knowledge for innovative…

Characterizes information retrieval systems in a network environment from a user's perspective along two axes: query and presentation. Several examples of early, current, and developing information retrieval systems are considered within this framework, and Daltext, a prototype system to support research on text-based retrieval systems, is…

Presents a way to model a large class of reference information based on a semantic network technique with embedded argumentation of the information provider. Shows by discussion of several alternatives that the approach is flexible enough to be adapted to different user and system requirements. (Author/AEF)

This paper describes and analyzes the models and methods used to evaluate asynchronous online learning networks and presents a "Systems Component Contexture Model" for conceptualizing the evaluation of online learning networks. The evaluation team finds it useful to divide the variables they examine into descriptive, process, and outcome…

Examines current OCLC practices and future possibilities under the leadership of K. Wayne Smith. Topics discussed include the changing roles of libraries, business, and government; the electronic information future; network possibilities, including the NREN (National Research and Education Network); future collaborations; online databases; and…

Discussion of standards and protocols (set of rules by which two computers or other electronic devices can exchange data for same purpose) highlights history of standards and their interaction with the design and evolution of real computer networks. Topics noted include reference models; conformance, compatibility, and interoperability; and…

Discusses the need for standards allowing computer-to-computer communication and gives examples of technical issues. The seven-layer framework of the Open Systems Interconnection (OSI) Reference Model is explained and illustrated. Sidebars feature public data networks and Recommendation X.25, OSI standards, OSI layer functions, and a glossary.…

This report examines subsections of the computer network topology that relate to end-to-end performance and capacity planning in schools. Active star topology, Category 5 wiring, Ethernet, and intelligent devices are assumed. The report describes a model that can be used to project WAN (wide area network) connection speeds based on user traffic,…

Considers a study of two models of name/title-derived search keys in a large online library network. Results predicted by the models are compared with results obtained from actual retrieval behavior of keys entered by users of the system. (FM)

Describes the Living Library, an idea to create a network of international cultural parks in different cities of the world using new communications technologies on-line in a garden setting, bringing the humanities, sciences, and social sciences to life through plants, visual and performed artworks, lectures, and computer and on-line satellite…

The Online Reference and Document Delivery Service Library Network developed at Eastern Oregon State College and operated in Eastern Oregon provides rural east Oregonians improved access to information sources via computers, telefacsimile, and telecommunications. Microcomputers have been placed in public, school, community college, and hospital…
