Students with intellectual disabilities are children who have limitations in thinking. These limitations result in students experiencing problems in self-development. Schools need to teach self-development to all students, regardless of any challenges the students may face. To achieve this, a specific strategy should be implemented to optimize the learning process. The use of audio-visual media is a great strategy to implement. This encourages students to participate in demonstrations while watching videos that showcase self-care in daily living activities, allowing them to gain practical experience. The learning media utilizes three senses, such as visual, auditory, and kinesthetic that allow students to watch the video, listen to the audio, and demonstrate some activities. The research method utilized in this project is Research and Development (R&D), with a 4D model design consisting of four stages, including definition, design, development, and dissemination. This case study for the implementation of audio-visual learning media was conducted in four special schools in Yogyakarta to test its effectiveness. The media was implemented in 4 special schools in Yogyakarta with 20 students (IQ range: 30-70). Using a one-group pre-test-post-test design, results indicated a significant improvement across all targeted self-care skills. The average normalized gain (N-Gain) score was 0.55, indicating a medium effectiveness level. Specific skills such as eating, drinking, dressing, and grooming showed N Gain values ranging from 0.51 to 0.65. These findings demonstrate that the multisensory media is moderately effective in enhancing daily living skills among students with intellectual disabilities. © 2025 IEEE.
