Lev Vygotsky's socio-cultural theory of cognitive development includes:
Zone of Proximal Development (ZPD): The distance between actual development level and potential development under adult guidance (A).
Intersubjectivity: The process whereby two participants who begin a task with different understandings arrive at a shared understanding (B).
Scaffolding (developed by Wood, Bruner, and Ross based on Vygotsky): Adjusting the level of support to fit the child's current performance (C).
Reciprocal Teaching (Palincsar & Brown, Vygotskian classroom model): Collaborative learning strategy where teacher and students take turns leading dialogues (D).
Sensory register, rehearsal, recognition, and recall belong to the Information Processing theory of memory (Atkinson-Shiffrin), not Vygotsky.
Thus, (A), (B), (C), and (D) only are correct.
वायगोत्स्की के सामाजिक-सांस्कृतिक सिद्धांत में जेडपीडी (ZPD), अंतःवैयक्तिकता (Intersubjectivity), मचान (Scaffolding), और पारस्परिक शिक्षण (Reciprocal teaching) शामिल हैं। (E) और (F) सूचना प्रसंस्करण सिद्धांत (Information Processing) के भाग हैं।
