Collaborative learning can occur peer-to-peer or in larger groups. Peer learning, or peer instruction, is a type of collaborative learning that involves students working in pairs or small groups to discuss concepts or find solutions to problems. Similar to the idea that two or three heads are better than one, educational researchers have found that through peer instruction, students teach each other by addressing misunderstandings and clarifying misconceptions.

More specifically, collaborative learning is based on the model that knowledge can be created within a population where members actively interact by sharing experiences and taking on asymmetric roles. (Rubén Mitnik)
Collaborative learning development enables developers of learning systems to work as a network. Specifically relevant to e-learning where developers can share and build knowledge into courses in a collaborative environment at a quick pace and typically lower cost. Knowledge of a single subject can be pulled together from remote locations using software systems. (Ananatharman, Latha)
