<![CDATA[Mathematical literacy plays a vital role in daily life, particularly in identifying, reasoning, communicating, problem-solving, and representing mathematical ideas in real contexts. However, for students with intellectual disabilities, developing mathematical literacy remains a significant challenge. To address this issue, innovative scaffolding through interactive and visual media is required. This study aims to develop NEIMoL media assisted by Augmented Reality (AR) that meets the criteria of validity, practicality, and effectiveness in improving mathematical literacy among students with intellectual disabilities. The research employed Plomp’s (1997) development model, which includes five stages: initial investigation, design, realization, testing and revision, and implementation. Data were collected through expert validation, observations, interviews, questionnaires, and mathematical literacy tests. Instruments included expert validation sheets, teacher and student response questionnaires, and pre-test and post-test assessments. The validation results showed the media to be “Very Valid” with an average score of 4.1 (on a scale of 5). Practicality was rated positively, with a score of 3.7, and both teachers and students expressed favorable responses. Effectiveness was demonstrated through an N-Gain score of 0.7175, categorized as high improvement. These findings indicate that AR-assisted NEIMoL media is valid, practical, and effective in supporting the mathematical literacy of students with intellectual disabilities.]]>
