<![CDATA[This study aims to determine the effect of animated video media on the ability to recognize vowels (a, i, u, e, o) in fourth-grade students with mild intellectual disabilities at Jember State Special Needs School. The research method employed is Single Subject Research (SSR) with an A-B design, consisting of two phases: the baseline phase (A), comprising five sessions, and the intervention phase (B), comprising eight sessions. The results of the analysis in the conditions show that the baseline phase has a percentage score of 35%–50% with a mean level of 42% and a stability range of ±3.7. The data within the stability range is only 1 out of 5 sessions, or 20%, so the data in the baseline phase is declared unstable. In the intervention phase, the percentage score increased from 45% to 85%, with a mean level of 68.7% and a stability range of ±6.3. The data in the stability range is only 2 out of 8 sessions, or 25%, so the intervention phase is also declared unstable. Although both phases exhibited unstable conditions based on the criteria (<80%), there was a significant increase in ability levels from Phase A to Phase B, from a high score of 50% to 85%, as well as a positive level change of +20. No overlap in data (0%) was found, which strengthens the intervention's influence on changing the target behavior. In conclusion, animated video media has been shown to have a positive effect on improving vowel recognition skills in students with mild intellectual disabilities. This study recommends the use of visual-interactive media such as animated videos in special education learning at special needs schools (SLB).
