J. R. Martin, 2017: "Revisiting field: Specialized knowledge in secondary
school science and humanities discourseg", Onomázein Special Issue SFL and LCT on Education and Knowledge, 111-148.
This paper revisits the register variable field in systemic functional linguistics (SFL), in
relation to the concept of ‘semantic density’ in Legitimation Code Theory (LCT). Re-interpretations
of the specialized meaning construing disciplinarity are proposed, from the perspective
of the ideational, interpersonal and textual metafunctions—highlighting technicality, iconization
and aggregation respectively. The term ‘mass’ is suggested as a cover term for these
resources. The paper contributes to an ongoing dialogue between SFL and LCT in relation to
research on secondary school history and biology discourse in Australian schools, an increasingly
productive exercise in transdisciplinary research.
