This study investigates how students experience and describe group work in an online course in international business (IB) after being introduced to Barnes' exploratory talk ground rules (ETGRs) which promote norms for dialog that encourage participants to share ideas and information and to think together. This study examines the dialog in groups of fourteen IB undergraduates attending a four-week online course in International Management. Initially, the students received briefings about the ETGRs and wrote self-reports throughout the course, on which we conducted a thematic analysis. Our findings show that students who engage with and apply the ETGRs describe more shared responsibility for collaborative learning in the group work, a greater interest in exploring the perspectives of group members, and overall, more positive learning experiences. This implies that making the ETGRs transparent is considered beneficial for social interactions in group work. However, the teacher plays a key role in creating a class environment conducive for collaborative learning, and preconditions for productive group work, including a good assignment structure and proper technology preparation, must be met. The findings and their implications are discussed herein.
