Social Literacies: Critical approaches to literacy development, ethnography, and education New York: Longman.

Every literacy is learnt in a specific context in a particular way and the modes of learning, the soical relationships of student to teacher are modes of socialization and acculturation. The student is learning cultural models of identity and personhood, not just how to decode script or to write a particular hand. If that is the case, then leaving the critical process until after they have learnt many of the genres of literacy used in that society is putting off, possibly for ever, the socialization into critical perspective (p. 140).
