Designed for middle and secondary pre-service and in-service English teachers, this text offers a fresh lens on grammar and grammar instruction. It shows how form, function, and use can help teachers move away from decontextualized grammar instruction and begin considering grammar in applied contexts of everyday use. An important feature is attention to the history of and current attitudes about grammar through a sociocultural lens, with ideas for teachers to bring discussions of language-as-power into their own classrooms.
