Transformative Inquiry: Integrating Action Research and Systems Thinking explores how two dynamic methodologies-action research and systems thinking-can be combined to address complex challenges in education, healthcare, organizational leadership, and public policy. Grounded in participatory, iterative processes, both approaches emphasize collaboration, reflection, and systemic improvement. Together, they provide a flexible yet rigorous framework for change.This edited volume brings together scholars and practitioners to examine the historical foundations, theoretical intersections, and applied integration of action research and systems thinking. Chapters include conceptual models and case studies drawn from K-12 schools, higher education, health professions education, digital learning environments, and leadership development. Contributors demonstrate how these frameworks support root-cause analysis, stakeholder engagement, and adaptive interventions that move beyond surface-level solutions.Each chapter illustrates how reflective cycles of inquiry, when combined with systems thinking tools such as feedback loops and mental models, can uncover persistent barriers and guide meaningful, context-sensitive change. Topics include digital equity, culturally responsive pedagogy, instructional redesign, performance improvement, and professional learning.Transformative Inquiry will be of interest to scholars, educators, researchers, and practitioners seeking tools for leading improvement in complex systems. It supports graduate and doctoral-level courses in research methods, systems change, and leadership, as well as professional learning in schools, universities, and organizations.
