This article elaborates an intra-active approach to action research, with examples from a recently started action research project carried out in collaboration with three preschools. The aim of the article is to contribute to the discussion about how practice-based research for change can take shape. Therefore, these questions are asked: Which concepts are central and what is produced in intra-active action research? Which potentialities for change are enabled via an intra-active approach to action research? New materialism theories, starting with Barad, are used to rethink action research, focusing on collaboration, movements, and change. An analysis workshop within the project, starting in circular and horizontal movements, inspired by Deleuze and Guattari through the work of Lenz Taguchi, is revisited. The intra-actions in the workshop produce both generative and undermining processes. Therefore, the intra-active action research approach implies that staying in the complexity of practices, rather than seeking to reduce the ‘messiness’, holds potentialities for change that unwind from the middle.
