Action research is a process where participants systematically examine their own educational practices using research techniques. It seeks transformative change through simultaneous action and research linked by critical reflection. There are different types including individual teacher research, collaborative research between teachers, and school-wide research. The action research process involves selecting a focus, identifying research questions, collecting and analyzing data, and reporting results. Benefits include focusing on school issues, professional development, improved collaboration and communication, and potential for school change. Fundamental research is driven by curiosity to expand knowledge without immediate practical application, while action research aims to solve specific problems through reflection and action.
