Whether technology can improve a work group′s productivity is one of the questions addressed in this volume, which examines how the use of computers and other electronic technology affects the behaviour of groups - and the results of a group′s endeavours. Contributors also discuss the conditions which make group meetings via computer as effective as groups that meet face-to-face and what technologies do to the groups that use them. They examine and relate the major conceptual ideas employed by various research groups through a systematic review of the theory and evidence in the field. The volume concludes with a condensed classification of empirical evidence from studies of electronic support in collaborative groupwork.
