The Palgrave International Handbook of Action Research offers a vivid portrait of both theoretical perspectives and practical action research activity and related benefits around the globe, while attending to the cultural, political, social, historical and ecological contexts that localize, shape and characterize action research. Consisting of teachers, youth workers, counselors, nurses, community developers, artists, ecologists, farmers, settlement-dwellers, students, professors and intellectual-activists on every continent and at every edge of the globe, the movement sustained and inspired by this community was born of the efforts of intellectual-activists in the mid-twentieth century specifically: Orlando Fals Borda, Paulo Freire, Myles Horton, Kurt Lewin. Cross-national issues of networking, as well as the challenges, tensions, and issues associated with the transformative power of action research are explored from multiple perspectives providing unique contributions to our understanding of what it means to do action research and to be an action researcher. This handbook sets a global action research agenda and map for readers to consider as they embark on new projects.
