This study explored the role of teachers in action research, extending beyond traditional classroom instruction to include professional development and scholarly inquiry. The primary aim was to investigate the practices involved in action research, teachers’ understanding of writing action research, and common challenges faced. Using a quantitative approach with a descriptive-correlational design, the study surveyed 497 teachers from 87 public schools across five districts in Agusan del Sur. Data collection focused on teachers’ techniques, skills, motivations, and problems related to action research. The study utilized stratified random sampling to ensure diverse representation and analyzed data using descriptive statistics and correlational analysis through IBM SPSS v29. Findings indicated that while teachers generally demonstrated competency and enthusiasm for action research, challenges such as time constraints, insufficient support, and research complexity were prevalent. The study revealed a strong correlation between teachers’ engagement in action research and their understanding of research methodologies and problem-solving abilities. Recommendations included providing ongoing professional development opportunities, enhancing institutional support, establishing mentorship programs, improving access to research resources, and creating recognition systems for research achievements. These measures aimed to bolster teachers’ research skills, overcome barriers, and foster a supportive environment for action research. The study emphasized the importance of further professional development and institutional support to enhance teachers’ competencies and address significant challenges in action research.
