The purpose of this assessment was to examine whether differences exist between students who self-select their classroom work group members and students who are randomly assigned to their classroom work groups in terms of their use of organizational citizenship behaviors with their work group members; their commitment to, trust in, and relational satisfaction with their work groups; and their self-reports of affective learning and cognitive learning. Participants were 126 students enrolled in a small group communication course. While students who self-select their group members and students who are randomly assigned to their groups do not differ in their use of organizational citizenship behaviors with their classroom work group members, students who self-select their classroom work group members do report higher levels of commitment, trust, and relational satisfaction, as well as more affective learning and more cognitive learning, than students who are randomly assigned to classroom work groups.
