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.
