ABSTRACT
Physics has its own object of study, its own ways of organising its knowledge and its own ways of expressing its knowledge. Sydney school genre pedagogy developed out of research into the types of texts students need to read and write across subject areas in primary (elementary) and high school. These projects were known as the Writing Project, Language and Social Power, and Write it Right projects. In recent decades, descriptions drawing on Systemic Functional Linguistics (SFL) have been developed for modalities of communication alongside language. SFL views language as a stratified system involving three levels (strata), known as discourse semantics, lexicogrammar and phonology/graphology. Cross-cutting strata, SFL proposes that language makes three broad types of meaning, known as ideational, interpersonal and textual meanings. Ideational meanings construe the outside world and in some sense organises our knowledge of reality. Interpersonal meanings enact our social relationships which organises our sociality.
