Action research is conducted by teachers, administrators or other educational professionals to systematically investigate and address specific problems within educational settings. There are two main types: practical action research which aims to improve short-term practice, and participatory action research which involves stakeholders as equal partners to enact social change. The key steps involve identifying a research problem or question, gathering relevant information through methods like surveys or interviews, analyzing and interpreting the collected data, and developing an action plan to address the problem based on findings. Action research has advantages like improving practice at a local level and empowering educators to develop solutions collaboratively.
