Teaching Metaphors

It is well known that metaphors are very useful when teaching, specially when teaching scientific concepts. One tries to simplify concepts by relating them to more familiar situations building bridges will be a good metaphor for these kind of explanations. Even to describe what teachers do has relied on metaphors, such a hicking/travel guide, sport coach in a reference to learning as a journey or a game. But this one is new for me: Professional Cook! This article by Natalie Houston in The Chronicle of Higher Education's blog "ProfHacker" http://chronicle.com/blogs/profhacker/streamlining-teaching-prep/38237 really makes a point about this metaphor. Hope you enjoy reading it.
