Action research is a scientific process used to solve practical problems in education. It involves teachers identifying issues in their daily work, defining the problems, collecting evidence, formulating hypotheses to address the causes of problems, testing solutions, evaluating the results, and determining if the problems were solved. The goal is to improve infrastructure, working styles, democratic attitudes, and generate a better learning environment at educational institutions. Key steps include identifying problems, defining them precisely, listing causes, creating action plans, choosing appropriate research designs, testing hypotheses through new teaching methods, evaluating outcomes, and determining if the problems were addressed. Benefits include developing scientific thinking in teachers and potentially raising student achievement and discipline, while disadvantages are that results cannot be widely generalized.
