Gilbert Ryle argued that cognition is not something that occurs solely inside an individual's mind, but is rather situated in social practices and interactions with the external world. He distinguished between "knowing-that" as factual knowledge, and "knowing-how" as practical skilled abilities. Researchers since then have further developed the idea that cognition is socially situated, occurring through embodied interactions between individuals and their shared social and physical environment. Sense-making is a collaborative process that involves verbal and non-verbal communication as well as the use of artifacts. Learning occurs through social interactions and participation in shared practices of a community.
