This paper argues that proactive behaviour, caused by high engagement and motivation of the learners, may lead to failure of collaborative learning. By examining empirical data from real-world text-only virtual negotiations between dispersed participants engaged in project-based collaborative learning, we discover that volunteering self-initiated activities promotes the participants’ individualistic behaviour. Also, the technology made it easy for participants to include their own statements in new contributions and deconstruct the statements of others, permitting few opportunities for others to influence proposals.
