General Background: Inclusive primary education requires learning approaches that accommodate the social and emotional needs of students with Autism Spectrum Disorder (ASD). Specific Background: Students with ASD may experience difficulties in social interaction, emotional regulation, communication, and understanding social situations, while conventional teacher-centered learning may limit their engagement. Knowledge Gap: Previous Augmented Reality research has largely focused on cognitive learning outcomes, while studies addressing social-emotional development among students with ASD, particularly in Indonesian inclusive primary schools, remain limited. Aims: This study develops and examines AR Puzzle media for supporting the social-emotional competence of fourth-grade students with ASD in an inclusive primary school. Results: Using Design-Based Research supported by a One-Subject Experiment with an A-B-A design, the study developed an AR Puzzle integrated with Pendidikan Pancasila content on rights and responsibilities. The media combines physical puzzle activities, visual scenes, three-dimensional AR animations, group collaboration, discussion, and reflection. The limited trial showed higher observation scores during the intervention phase than the initial baseline, with the second baseline remaining above the initial baseline. The media supported student attention, engagement, conceptual understanding, and social-emotional activities. Novelty: The study integrates AR Puzzle with the CASEL social-emotional framework for ASD learning in an Indonesian inclusive primary school context. Implications: AR Puzzle provides a concrete, visual, interactive, and contextual learning medium that can support inclusive learning while allowing further development of visual characters and learning scenarios. Key Findings Highlights Intervention scores remained above the initial baseline during the A-B-A trial. Visual scenes and group activities supported attention, engagement, and social-emotional learning. Expert feedback identified the need for more varied three-dimensional character expressions.
