For most Anglophone countries, the history of grammar teaching over the past 50 years is one of contestation, debate and dissent: and 50 years on we are no closer to reaching a consensus about the role of grammar in the English/Language Arts curriculum. The debate has been described through the metaphor of battle and grammar wars (Kamler, 1995; Locke, 2005), frequently pitting educational professionals against politicians, but also pitting one professional against another. At the heart of the debate are differing perspectives on the value of grammar for the language learner and opposing views of what educational benefits learning grammar may or may not accrue. At the present time, several jurisdictions, including England and Australia, are creating new mandates for grammar in the curriculum. This article reviews the literature on the teaching of grammar and its role in the curriculum and indicates an emerging consensus on a fully-theorized conceptualization of grammar in the curriculum.
