A colleague recently sent me a pdf file (link out of date, try this one) titled “Pedagogy vs Andragogy” which was contrasting and comparing the different approaches to learning. Andragogy was originally defined as the art and science of teaching adults how to learn by Alexander Krap in 1833 and then further developed into a full theory of adult education by Malcolm Knowles.
Anyway, it seems to me, that in developing our students to become more independent learners that we need to be pushing towards a more Andragogical model of learning most of the time. Perhaps Pedagogy and Andragogy are more of a continuum than absolute concepts. If we view it that way, then all educators should be constantly striving move towards andragogy.
