The document provides an overview of cognitivist learning theories, including those proposed by Piaget, Vygotsky, and Bruner. Some key points of cognitivism are that learning is an internal process of associating new information with prior knowledge, and that learning involves input, processing, and output of information. Piaget's theory proposed that children progress through distinct stages of cognitive development. Vygotsky emphasized the social aspects of learning and proposed the zone of proximal development. Bruner viewed learning as an active process where learners construct new understandings based on previous knowledge.
