This document discusses key aspects of action research, including that it involves teachers systematically reflecting on issues in their immediate context to develop and test hypotheses for effecting change. The document also examines debates around the validity and generalizability of action research findings given that practitioner-researchers are insiders studying their own settings. Additionally, it explores tensions between the empowerment of school practitioners through action research and challenges to the traditional hierarchy between universities and schools. The document emphasizes that action research is most effective when collaborative and when findings are shared to build alliances rather than threaten others.
