Current landscapes of curriculum discourse and educational practice are examined by focusing on co-evolutions of metaphors for knowledge, learning and teaching across four prominent 'frames'--namely, Standardized Education, Authentic Education, Democratic Citizenship Education and Systemic Sustainability Education. It is argued that these frames become compelling and resilient (or repulsive and nonsensical)--not because of what they explicitly assert, but because of the coherence of their implicit webs of vocabulary, metaphor, image and ideological association. While some of these frames/webs may be embraced as complementary, more often they are treated as conflicting or incoherent--in part, it would seem, because of tensions among their mainly implicit substrates of figurative association.
