This research aimed to improve the literacy of reading and writing among elementary school students affected by the eruption of Mount Sinabung. The identified problem was the low literacy skills of the learners. The factors causing this issue were that teachers still preferred using conventional teaching methods dominated by lecturing without implementing learning models and instructional media focused on textbooks. Another obstacle was the ongoing disaster condition, leading to students experiencing trauma. To address these problems, the researchers implemented the cooperative learning model with the "keliling" (round robin) technique, supported by audiovisual media. The research method incorporated was action research based on McNiff's theory. The present research data was collected through tests, assignments, observations, and field notes. The data validity was ensured through careful observation, triangulation, peer checking, and input from school members. Subsequently, the data were analyzed using quantitative and qualitative data analysis methods. Ultimately, the research concluded that there was an improvement in students' reading and writing literacy by implementing the cooperative learning model with the round robin technique supported by audiovisual media. The improvement was evidenced by the average scores for writing (74.6) and reading (73.33) and a significant increase in students' learning motivation (75.11%).
