（重定向自Androgogy）
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.
