his theory focuses on the role of social interaction and culture in cognitive development via the child internalizing the understanding of experts(more knowledgable others)
internalization of understanding leads to cognitive development
social interaction with people from our culture allows us to see problem solving skills(cognitive tools) and then internalize it
cognitive tools like reasoning and language allow us to understand how the world works and go on to shape our cognitive development
language allows us to shift from basic mental functions to higher mental functions
language facilitates thoughts via external monologues and this eventually develops into internalized speech
internalized speech eventually leads to internalized thoughts
internalized thought leads to language development showing how culture leads to cognitive development via said cognitive tools
learning takes place in the gap between what a child currently understands by themselves and what a child can understand with an experts help - this is the zone of proximal development
expert assistance and scaffolding allows a child to cross the zone of proximal development
crossing the ZPD leads to a higher level of understanding . Vygotsky stated higher mental functions are only acquired through interactions with experts
scaffolding refers to any support framework an expert provides to a child to enable them to cross the ZPD
scaffolding allows the child to learn but it should be gradually withdrawn to help children perform independently and fascillitate cognitive development
bruner wood and ross furthered vygotskys work by identifying five aspects of scaffolding hat help a child understand expert knowledge
getting a child to focus on a task to start solving it is part of scaffolding
engaging and retaining a childs attention on a task is part of scaffolding
encouraging the child to maintain effort and focus is part of scaffolding
highlighting the most critical features of the task clearly for the child is part of scaffolding
demonstrating for the child how to perform the task is part of scaffolding
