This document discusses collaborative learning for distance students. It begins by asking why distance students should collaborate and what the best ways to help them collaborate are. It then addresses whether students like collaborating or experience problems, and most importantly whether collaboration works. The document covers mentoring as an effective way to help students collaborate that has been shown to increase retention rates cost-effectively. It also discusses peer collaboration online and problems students may face, providing potential solutions like giving students control over collaboration partners or making participation part of assessment. While more evidence is still needed, some research shows mentoring can be an effective and cost-efficient approach to collaborative learning for distance students.
