As peer learning is gaining importance, there is a growing body of research that shows the benefits of peer learning in schools, universities and workplaces. The research shows that peer interactions and learning have strong underpinnings in neuroscience and psychology of learning and demonstrates that peer learning is much more than extracting the tacit knowledge of employees. The emerging scientific evidence explains why interactive learning environments like peer learning groups promote intrinsic motivation to learn, greater collaboration and better on-the-job performance. The following are some of the recent research related to the peer learning effects for improved workplace outcomes.
