The British Educational Research Association (BERA) has promulgated a concept of close-to-practice research that is seen as vital to defending and promoting education as an academic discipline. However, what is overlooked are the questions of what education is for and what educational practice is--questions that need to be addressed for any research aiming to understand and improve educational practice. Informed by Robin Alexander's conception of pedagogy, continental "Pädagogik" and "Didaktik" and Anglo-American sources, this paper advances an alternative, different way of thinking about close-to-practice research and education as a discipline. It makes a case for education as a distinctive discipline directed towards the understanding and development of practice for the advancement of education. This discipline necessitates an educational and "Didaktik" way of thinking and theorising, centred on the questions of what education is for, what educational practice is and how practice is supported and developed. This way of thinking and theorising calls for three interrelated lines of research that are significant and matter to practice, particularly within the current context of the National Curriculum in England.
