Constructivism is a learning theory that posits that learning occurs as learners are actively involved in a process of meaning and knowledge construction as opposed to passively receiving information. Key aspects are that learning is an active process, that learners construct new ideas based upon their current and past knowledge, and that learners socially construct knowledge through interactions and discussions with others. Theorists associated with constructivism include Piaget, Vygotsky, Dewey, Bruner, and others.
