The goal of the series is to publish the best new books—both research monographs and textbooks— that contribute to an understanding of technology as a crucial facet of human activ- ity enacted in rich social and physical contexts. The focus of the series is on tool-mediated processes of working, playing, and learning in and across a wide variety of social settings. The series explores devel- opments in postcognitivist theory and practice from the fields of sociology, com- munication, education, organizational studies, science and technology studies, human-computer interaction studies, and computer-supported collaborative work. It aims to encompass theoretical frameworks developed through cultural-historical activity theory, actor-network theory, distributed cognition, ethnomethodology, and grounded theory. In Group Cognition: Computer Support for Building Collaborative Knowledge, Gerry Stahl challenges us with the provocative notion that “small groups are the engines of knowledge building.” He notes that research on learning has focused on either individual cognition or the larger community. Based on his extensive experi- ence in teaching and system building, Stahl points to the “decisive role of small groups” in learning. Stahl’s contribution is to alert us to the need for a theoretical representation of small groups and their pivotal role in group cognition. He explores this theme in varied ways—empirical, theoretical, philosophical—each persuasive and thoughtful in its own way. Stahl pushes hard on the notion of group cognition, proposing that we view dis- course as a “substrate for group cognition.” Discourse is defined broadly to include spoken words, inscriptions, and body language. Using these notions, Stahl hopes to position cognition in that zone of small groups
