Placing students in groups does not guarantee collaboration. A combination of complex approaches that reinforce and enhance collaborative learning and social interaction amongst group members are essential. This article suggests three approaches:

• Cognitive approach of promoting epistemic fluency.
• Direct approach of structuring task-specific learning activities.
• The conceptual approach of applying a set of conditions to stimulate/stress collaboration.

These methods encourage social interaction in ways that encourage elaboration, questioning, rehearsal, and elicitation.
