I too learn more deeply outside of the confines of a structured class. However, I find the structure of an OCW course nearly ideal for many subjects. For me it seems to be at least partially a function of my ability in an area. The stronger I am in a subject, the less structure I need. I suspect the optimal amount of structure varies from person to person and within a person from subject to subject. People learn differently.
