This study investigates how model presentation, collaboration, discussion, and peer feedback as the intervention of participatory action research (PAR) improved students' academic writing (AW) and presentation skills while dealing with a practical course ‘ELT seminar and report writing’. We implemented the intervention for three months in our regular class with 30 students pursuing a Master's Degree in English Education from Tribhuvan University, Nepal. During the intervention, we used observation notes and after the intervention, we used semi-structured interviews (with 15 students) to collect data. The findings showed that the intervention significantly improved the students' AW and presentation skills. The findings also showed that students refined their writing skills by gaining insight from the model presentation, discussions, and feedback. They significantly improved their writing and presentation skills through collaborative tasks performed regularly during the study. The study suggests that model presentation, group discussion, peer and teacher feedback, and self-reflection can be effective in enhancing students' AW and presentation.
