http://eksperci.edu.pl The topic of learning from subject specialists gives me a few things to think about, especially when the discussion moves beyond general advice. A specialist's example can show how a broad principle applies to a particular problem. That is the kind of detail I would keep in mind while exploring expert learning guidance. The part I would like to explore further is what happens when the idea meets a real situation with its own limitations. What makes an expert explanation useful to someone with little background knowledge?
