For me, what matters is not necessarily the content, but the conditions created that provide the possibility for personal problem solving. To reword Rushkoff’s question, is professional development meant to solve our riddles or pose new ones?
I was intrigued by your statement about being an ‘expert on learning’:
I really believe that people educating room full of experts on learning should be absolute masters of learning – otherwise they’re hardly qualified to be doing that job.
I wonder if all learning is the same and with that if all professional development is the same?
