even when children have different audiences and purposes for writing, narrative dominates because teachers frequently do not know how to explicitly support other genres, and yet "every teacher is a language teacher, responsible for helping all students develop the linguistic tools that will enable them to learn and share what they have learned" (Schleppegrell, 2006, p. 11). The argument from the point of view of functional linguistics is that the bias towards narrative is damaging, limiting experience of the powerful meaning- making expository and analytic genres; unless teachers are in a position to make reference to such linguistic structures in assessing pupils' work, they will not be able to make written language available to all students.
