Knowles asserted that andragogy (Greek: "man-leading") should be distinguished from the more commonly used pedagogy (Greek: "child-leading").
Knowles' theory can be stated with six assumptions related to motivation of adult learning:[1][2]
Adults need to know the reason for learning something (Need to Know)
Experience (including error) provides the basis for learning activities (Foundation).
Adults need to be responsible for their decisions on education; involvement in the planning and evaluation of their instruction (Self-concept).
Adults are most interested in learning subjects having immediate relevance to their work and/or personal lives (Readiness).
Adult learning is problem-centered rather than content-oriented (Orientation).
Adults respond better to internal versus external motivators (Motivation).
The term has been used by some to allow discussion of contrast between self-directed and 'taught' education
