Features Unique to Lev Vygotsky’s TheoryEmphasis on Social Interaction and Culture – Cognitive development is strongly influenced by social interactions and the cultural context in which a child is raised.Zone of Proximal Development (ZPD) – The ZPD is the range between what a learner can do independently and what they can do with guidance and support from a more knowledgeable other (e.g., teacher, peer).Learning Can Lead to Development – Unlike Piaget, who believed development precedes learning, Vygotsky argued that learning can actually drive development when instruction is given within the ZPD.Scaffolding – Temporary support provided by a more knowledgeable person to help the learner master a task. As the learner becomes more competent, the support is gradually removed.Language as a Tool for Thought – Language is not only a means of communication but also a central tool for cognitive development. Inner speech (talking to oneself) plays a key role in thinking and problem-solving.More Knowledgeable Other (MKO) – Cognitive growth is often facilitated by interaction with someone who has a higher level of knowledge or skill, such as a teacher or peer.Cultural Tools and Symbols – Tools provided by culture (e.g., language, counting systems, writing) shape the way individuals think and solve problems.[tex][/tex]
