Legitimate peripheral participation (LPP) is a theory that describes how individuals learn by participating in the activities of a community. In this theory, learning is seen as a social process that occurs through interaction with others. LPP has been studied in a variety of contexts, including schools, workplaces, and communities. Researchers have found that LPP can be an effective way to promote learning, as it allows individuals to learn from more experienced members of a community and to develop the skills and knowledge necessary to become full participants in that community.
