As I work on my conversation paper, which draws on Gibbons’ use of conversation as a metaphor for instruction, I’m wondering: what are the other explicit metaphors which have been made for instruction?  I read Anna Sfard’s article comparing the “acquisition” and “participation” metaphors — but these are actually metaphors of learning more than of instruction.  (Students learn by acquiring information or by participating in the construction of information.)  I feel like I have read a bzillion metaphors for instruction, but at this moment can’t recall any of them!
