The field of Systemic Functional Linguistics (SFL) was first
outlined by Michael Halliday and his colleagues (Halliday 1994; Martin 1992 in
White, Mammone & Caldwell, 2015, p. 259). Systemic Functional Linguistics
rejects traditional, structural models of teaching grammar that are focused on
rules and “correct or incorrect usage” (Kongpetch, 2003, p. 86), instead
focussing on how language is used in society. “Language has evolved to satisfy
human needs; and the way it is organised is functional with respect to those
needs” (Halliday, 1994, p. xii). White et al. (2015, p. 259), summarise the
ways that SFL describes meaning-making in language:
It understands language to
provide three broad modes of meaning making:
(1) interpersonal meanings by which social roles, identities and relationships
are construed, (2) ideational meanings by which particular representations
of the experiential world are formulated and (3) textual meanings by which
these interpersonal and ideational meanings are managed and interrelated
in unfolding communicative events (texts).
SFL recognises that text evolves into some context. Central
to this theory is the concept of the context
of situation (Halliday, 2009 in Payaprom, 2012, pp. 11-12) which is defined
in three areas. Field consists of who
or what is involved and the circumstances surrounding the activity. Tenor comprises the interlocutors, their
status and language choices and the mode
entails the channel of communication being used, the symbols in any messages,
how they are interpreted and how language choice is affected by these factors. The
situational context which overrides
all of these is called the register. The
register is different in texts with different contexts (Payaprom, 2012, p. 12).
Eggins (in Payaprom, 2012, p. 19) summarises these concepts in the diagram
below.

SFL allows students to “predict the nature of language and
the recurring linguistic pattern of language in a particular context”
(Payaprom, 2012, p. 10). These textual patterns and conventions are the focus
of the genre based approach.
The genre-based approach to grammar became popular in the
Australian educational context from the late 1980s and it replaced “growth and
process” methods that had previously been popular from the 1970s (Ahn, 2012, p.
3; Christie, 2013, p. 12; White et al., 2015, p. 258). It focuses on
identifying specific “text types” (Christie, 2013, p. 14) that are common in
the English classroom and the examination, dissection and composition of these
genre based textual items (Frow, 2004, p. 1627). The genre-based approach focuses
on using explicit instruction of texts and their conventions to aid students in
constructing meaning that is relevant to the Australian cultural context (Ahn,
2012, p. 3). Knapp’s genre model (Knapp, 1992 in Knapp and Watkins, 2005, p.
27) defines the genres of describing, explaining, instructing, arguing and
narrating which he asserts are “social processes” which in turn create “products”
and “multi-generic products”.
As the theory developed different linguistic traditions
adapted it in different ways. Hyon 2007 (in Ahn, 2012, p. 12) classifies the
three schools of genre approaches in the table below.
