Sociocultural Theory, developed by Lev Vygotsky, emphasizes the importance of social interactions and cultural context in cognitive development. It posits that learning occurs through engagement with others, particularly in collaborative settings. This theory highlights the role of language and cultural tools in shaping thought processes, suggesting that individuals learn best when they are supported by more knowledgeable peers or adults. Central to Sociocultural Theory is the concept of the Zone of Proximal Development (ZPD), which refers to the difference between what a learner can do independently and what they can achieve with guidance. This framework encourages educators to tailor their teaching strategies to meet students' needs, fostering a more effective learning environment.
