1. Introduction
For the past several years group work in organizations and in educational settings is being conducted in settings other than face-to-face environments. For example, phone conferences are popular modes of accomplishing group tasks. Of late, in educational settings systems such as Blackboard and WebCT have made it possible for groups of students to transcend time and space boundaries. No longer must cooperative learning always occur in face-to-face settings. Collaborative learning technologies (CLT), also known as group support systems (GSS), facilitate students' group work by allowing them to conduct “virtual meetings” both synchronously (chat) and asynchronously (bulletin-boards). Thus, CLTs help solve the problem of dominant or shy students and the need for each student to wait for his or her turn in order to participate. A number of recent studies have examined various aspects of collaborative technologies on group decision making (see [10] for a recent comprehensive review of GSS research).
