The last time I attended a course in order to learn was in 1977. I went for a short introductory course recently. It was a social science course and the pedagogy was excellent. The co-learners were a mixed lot from a 21 year old undergrad to me, a 60 year old. there were professionals with varying experience, and laypeople like me who had never studied social science. Perhaps the experienced people were disappointed in the course, but I found it really interesting with not a dull moment.
