Andragogy - the art and science of adult learning
Malcolm Knowles (1913-1997) was an American educator well known for the use of the term Andragogy as synonymous to the adult education.
In 1980, Knowles made 4 assumptions about the characteristics of adult learners (andragogy) that are different from the assumptions about child learners (pedagogy). In 1984, Knowles added the 5th assumption.
