Action research is a method that integrates action (implementing a plan) with research (understanding the effectiveness of the implementation). It was developed by Kurt Lewin in the 1940s. Unlike traditional academic research, action research involves participants collaboratively identifying issues in their organization and developing improvement processes. It aims for positive educational change through flexible, ongoing cycles of planning, acting, observing, and reflecting. Action research can be conducted individually by teachers, collaboratively between teachers, or on a wider scale across entire schools or districts. The goal is to solve practical problems and improve practices in real-world settings.
