Learning about Learning

As I sat in the rear of the classroom at Fresno State, and listened to Dr. Timothy Kubal, professor of Sociology, lecture on "qualitative research," I thought about the practice of learning-and, though I was also the professor for the class, that, there I was, taking notes, listening, and trying my best to soak in every word, every thought, every idea--because I craved the new knowledge, I wanted to "put it all together" with the things that I have learned, or heard, before, and I wanted to lock the information in my mind--like a newly discovered treasure--and, yet, it was not even all that new--but, it was a new articulation of information that somewhere along the line of life, I had learned: so, I thought about learning.
When have we "learned" something?
When do we really KNOW? Is this epistemology about putting the information into a pragmatic, workable form, is is true that "learning is change?" If so, how does this information change me? Perhaps I was enjoying the new language-since my field is not sociology, but, education and theology--and, so, this new language, or this new articulation of truth fascinated me and prompted me to find more readings about qualitative research, and continue my learning- all, which made me realize, with some happiness, that I have a lot to learn about learning.
