Andragogy
Andragogy is the theory and practice of education of adults. The word is a combination of andro (from Ancient Greek: ἀνήρ, anēr, genitive ἀνδρός, andros, "man") and ἄγω (ágō), meaning "to lead", it arose from the practice of pedagogy to address the specific needs in the education of adults as opposed to the education of children.
Definitions
Two primary understandings of ‘andragogy’ currently exist:
The science of understanding (= theory) and supporting (= practice) lifelong and life-wide education of adults.
In the tradition of Malcolm Knowles, a specific theoretical and practical approach, based on a humanistic conception of self-directed and autonomous learners and teachers as facilitators of learning.
Interpreted broadly throughout the academic literature, the term also invites such definitions as ‘adult education practice,’ ‘desirable values,’ ‘specific teaching methods,’ ‘reflections,’ and ‘academic discipline,' with many authors claiming it to be better than traditional adult education.
