What theory highlights the importance of peer interactions in learning?

Vygotsky's Social Development Theory emphasizes the significance of social interactions in the learning process, particularly through collaboration and dialogue among peers. According to Vygotsky, cognitive development is largely driven by social interaction, as individuals learn from one another and build knowledge through shared experiences. His concept of the "Zone of Proximal Development" illustrates how learners can achieve higher levels of understanding and skill acquisition with the guidance of more knowledgeable peers or adults. This highlights the crucial role that peer interactions play in facilitating learning and cognitive growth, distinguishing Vygotsky's theory from those that focus solely on individual learning processes.
