Thank you Katrina. I can see how the two terms differentiated by age of learner, but I think the world would be a better place if they had not. There are many teaching concepts from K12 that would fit well in andragogy such as constructivism, student-centeredness, authentic materials, authentic assessment and self-assessment, but they often seem to get badly misinterpreted when put into practice. I think these things are imperiled even in adult education.

Perhaps a reason why is that teachers tend to teach the way they were taught. We are prisoners of our own experience. This is how educational traditions perpetuate. It is extremely difficult to break out, and when we do, we encounter students who say, "just give me the workbook." I guess students are prisoners of their experience too.
