Metacognition is defined in simplest terms as “thinking about your own thinking." The root “meta" means “beyond," so the term refers to “beyond thinking." Specifically, this means that it encompasses the processes of planning, tracking, and assessing your own understanding or performance.
The phrase was termed by American developmental psychologist John H. Flavell in 1979, and the theory developed throughout the 1980s among researchers working with young children in early cognitive stages.
