Vygotskian Theory, developed by Lev Vygotsky, emphasizes the importance of social interaction in cognitive development. It suggests that learning occurs through collaboration with more knowledgeable others, such as teachers or peers, who provide guidance and support. This process is known as the Zone of Proximal Development (ZPD), where learners can achieve higher levels of understanding with assistance. Additionally, Vygotsky highlighted the role of cultural tools, including language, in shaping thought processes. He believed that language not only facilitates communication but also influences how individuals think and learn. This perspective underscores the interconnectedness of culture, language, and cognitive development.
