The London Association for the Teaching of English is a subject group that was founded in 1947 to ‘provide a live forum for the exchange of ideas, and to undertake the practical study of problems connected with the teaching of English’. The early history of this Association, its influence on the development of English pedagogy and practice is the subject of my current PhD research. Within this work are key questions about the nature of subject English, the curriculum, and the ways in which members of a subject community work together to effect change. This article gives some background to the research project, and begins to point towards some potentially important questions about the subject and ways of working together. After two decades of top down, centralised government initiatives around English pedagogy, curriculum and assessment, and teachers’ professional development, these questions are worth addressing. 相似文献
