As a university professor, I have a hard time accepting as professionals in education we insist on using a pedagogy style to instruct adult learners. According to Malcolm Knowles chart, the andragogical learner is more suited for on-line learning because 1) Increasingly self-directed, 2) rich resource for learning by self and others, 3) develops from life tasks and problems, 4) task or problem-centered, and 5) internal incentives and curiosity driven. Keeping this in mind, as a facilitator I would allow my students to take turns selecting an appropriate topic for discussions and set up groups to work together on certain subjects. Do you instruct using a pedagogy or andragogy style? Is that style reflected in your online courses?
