Constructivism is a category of learning theory in which emphasis is placed on the agency and prior "knowing" and experience of the learner, and often on the social and cultural determinants of the learning process. Educational psychologists distinguish individual (or psychological) constructivism, identified with Piaget's theory of cognitive development, from social constructivism. The social constructivist paradigm views the context in which the learning occurs as central to the learning itself. It regards learning as a process of enculturation.  People learn by exposure to the culture of practitioners. They observe and practice the behavior of practitioners and 'pick up relevant jargon, imitate behavior, and gradually start to act in accordance with the norms of the practice'. So, a student learns to become a mathematician through exposure to mathematician using tools to solve mathematical problems. So in order to master a particular domain of knowledge it is not enough for students to be learn the concepts of the domain. They should be exposed to the use of the concepts in authentic activities by the practitioners of the domain.
