Action research is characterized as research conducted by teachers to examine their own classrooms and improve the quality and effectiveness of their instruction. It is a cyclical process that involves identifying an area of focus based on problems or questions within a teacher's practice, collecting and analyzing data related to the issue, taking action such as implementing a new strategy, and reflecting on the results. The goal of action research is practical change and improved student outcomes rather than generalization to larger populations. It allows teachers to explore solutions to site-specific problems and test innovations in a collaborative manner.
