In this article, the authors argue for paying close attention to the materiality of practice in understanding the work of teacher educators; specifically, the meanings of artefacts used by teacher educators in the course of their daily work. They locate this analysis within a dialectical materialist understanding of the development of human activity, providing examples of artefacts-in-use in initial teacher education and the meanings accorded to these artefacts by the teacher educators they observed and interviewed. Their aim is to make a case for what is afforded epistemologically when researchers pay attention to artefacts from a dialectical materialist viewpoint.
