Distributed Cognition

Distributed cognition is a theory holding that cognitive processes are not confined within an individual's head but are distributed across a system that includes other people, physical tools and the surrounding environment, developed principally by cognitive scientist Edwin Hutchins and set out in his 1995 book Cognition in the Wild, based on his study of a ship's navigation team coordinating instruments, charts and each other to accomplish a task none of them could perform alone. In education, distributed cognition reframes learning as something that happens not only inside a single learner's mind but through interaction with physical and digital tools, such as calculators, diagrams, textbooks and computer software, and through collaboration with other learners, so that intelligent performance is properly understood as a property of the whole system of person, tool and environment together rather than of the individual mind alone. The theory has informed research on collaborative and technology-enhanced learning environments, where the design of shared tools and representations is treated as central to supporting cognition rather than as a neutral backdrop to it.
