A Personal Learning Network (PLN) is an informal learning network that consists of the people a learner interacts with and derives knowledge from in a personal learning environment. In a PLN, a person makes a connection with another person with the specific intent that some type of learning will occur because of that connection.
Personal learning networks share a close association with the concept of personal learning environments. Martindale & Dowdy describe a PLE as a "manifestation of a learner’s informal learning processes via the Web".
