Looking in classrooms is one of the most basic requirements of school improvement, and yet it is one of the least practised skills of teachers and one of the most contentious methods of educational researchers. When it does occur, it is difficult to agree on what to look for and even more difficult to agree on what is seen. This paper outlines an approach to recounting classroom practices adopted in a three-year study of four schools in New South Wales (NSW) that were all characterised by high levels of poverty and difference. The research examined the processes and conditions under which these schools were attempting to bring about improvements in student learning. The creation of jointly produced accounts of classroom practice, what we have called day diaries, provided opportunities to examine teaching and leadership practices in schools. It also revealed that, for the most part, classroom practices in the participating schools followed a standard and widely adopted script. We argue that disrupting this script requires innovation and the production of new knowledge about what works in the local context, and that such innovation is most needed in high poverty contexts.
