Which theorist emphasized the importance of social interaction in learning?

Lev Vygotsky emphasized the importance of social interaction in learning, making him a pivotal figure in educational psychology. His theory, often referred to as sociocultural theory, asserts that cognitive development is significantly influenced by social interactions and cultural contexts. Vygotsky introduced concepts such as the Zone of Proximal Development (ZPD), which illustrates that learning occurs most effectively when a child interacts with more knowledgeable peers or adults. This collaborative learning process allows children to acquire skills and knowledge that they would not be able to grasp independently.

By highlighting the social nature of learning, Vygotsky underscored the role of language and communication as essential tools for cognitive development. His ideas shifted the focus from isolated individual learning processes to the communal and relational aspects of education, which have had a profound impact on modern teaching practices and curriculum design.
