I put this reading list together after attending a professional development program in which the presenters spent considerable effort at the start gathering information from participants about what we already knew about the subject, and what we wanted to know. Prior knowledge and experience and learning needs -- very good, no? These presenters knew what they are doing. Not quite. They then delivered their prepared show and tell without once referring to what they had discovered about our experiences at the start, as if those experiences made no difference whatsoever.
