In Australia and Aotearoa New Zealand, the impetus to create open learning spaces that afford spatial and pedagogical flexibility have disrupted the nature of teachers' work. In redesigned education facilities, teachers engage in sophisticated processes of collaboration and ongoing teacher professional learning. Moving from traditional classroom designs brings with it a shift in how knowledge is transmitted, co-produced and engaging with aspirational pedagogy and attending to the power dynamics of students and teachers and teachers as co-collaborators. Using a patchwork metaphor to frame our methodological approach, examples from research projects into teachers' work from across Aotearoa New Zealand and Australia addresses the question: "What is involved in high-quality teacher collaboration in Innovative Learning Environments?" This patchwork of practice is intended to support the work of those charged with researching, reviewing and enhancing collaboration in ILEs. Specifically, dimensions of alignment, acculturation, adaptation, aspiration and agency can inform teacher professional learning and development. By examining the complex conditions of ILEs in a range of projects, where teachers are no longer alone in teaching but contribute to both short-lived and sustained collaborations, we identify examples from research that illustrate new teaching realities in ILEs, and frame possibilities for action.
