In this paper a former middle school principal and his dissertation chair look back at the research process envisioned and carried out against the neo-positivist grain aggressively put forward by the government and espoused in school districts across the United States. We revisit the meaning of data and show how they emerged from the paradigmatic stance of action research and came to life via collaboration between teachers-research participants and a school principal-researcher. We provide examples of data that was simultaneously collected and interpreted and served as evidence that the process of action research resulted in meaningful learning, genuine change, and reflective instructional practices.
