It explains that these models are primarily concerned with what occurs in writing and aim to provide students the ability to use writing codes efficiently and effectively. It describes four perspectives on language: context, genre, text, and grammar. Context refers to how texts relate to social environments and other texts. Genre describes textual categories. Text looks at characteristics of different text types. Grammar examines the formal, functional, and figural aspects of English grammar and how language represents things. The document connects genre, text, and grammar, describing genre as the social context, text as language processes, and grammar as choices in constructing words into texts.
