Deleuze and his colleagues, particularly Guattari, have had a profound impact on a number of fields of study. The authors argue that their work offers a range of images to help think about and write action research, a way that acknowledges and celebrates the complexities of the sites of action. The article has a divided structure, coherent with the style of Deleuze & Guattari. The authors present some Deleuzian ideas, particularly the concept of rhizomatic growth, and show how they might profitably be used to analyse and write accounts of action research, reflecting the multiplicities of practice, in this case within education. They have shown the potentialities of the "rhizome" as a way to rethink the field of action research, imagining a new epistemology (in which the concepts work, rather than represent) and how the rhizome demands experimental forms of writing ourselves in action research. They show a cartography (of smooth and striated space) that is required to think rhizomatically about action research. (Contains 1 figure.)
