Constructivism is a learning theory that suggests people actively construct their own understanding and knowledge through experiences and reflecting on those experiences. Key founders of constructivism include Jean Piaget and John Dewey. According to constructivism, learning involves a process of assimilation of new information and accommodation or adjustment of existing knowledge. Constructivism emphasizes hands-on, active learning and problem solving over rote memorization. It suggests learning occurs through collaboration and social interaction.
