Traditionally, collaborative technologies are intended to directly support joint, collaborative activity, taking their cues from communication and media. Here, empirical findings are presented about the types of information needs associated with the formation of a knowledge-building community among professional learning technology researchers. Several issues are outlined in designing, facilitating, supporting, and measuring knowledge-building activity in such as community of practice. It is argued that, rather than communication tools, a knowledge-building community is better served by
"Computer-mediated communication" refers to communication between people that occurs through the medium of the computer, and includes email, instant messages, chat rooms, newsgroups, and blogs. Learning sciences researchers have made great progress in understanding how CMC can be used to connect learners together, and to allow learners to connect with society at large.
The notion that science is unified in one way or another dates back at least to Aristotle, though unity claims since then have been diverse and va riously motivated. By way of introduction to the modern discussion of unity, disunity, and integration, in this first section we examine five historical attempts to unify knowledge: Aristotle’s metaphysical and hierarchical unity; the Enlightenment project of the French Encyclopedists; the systematic unity of Naturphilosophen Lorenz Oken; the methodological unity of the Vienna School’s Encyclopedia of Unified Science; and finally, the organizational
