Lifelong learning
Two theories of particular relevance when considering lifelong learning are cognitivism and constructivism. Cognitivism, most notably Gestalt theory, speaks of learning as making sense of the relationship between what is old and what is new. Similarly, Constructivist theory states that "knowledge is not passively received from the world or from authoritative sources but constructed by individuals or groups making sense of their experiential worlds". Constructivism lends itself well to Lifelong learning as it brings together learning from many different sources including life experiences.
