<![CDATA[Science and social science learning on Indonesian cultural material in elementary schools is often faced with a lack of concrete learning media, resulting in low student participation and collaboration skills. This study aims to develop and test the validity, feasibility, and effectiveness of Culture Smart Box media based on TABUDI gamification in improving the collaboration skills of fourth-grade students at SDI Ma’arif Tawangsari Garum, Blitar Regency. This research and development study applies the ADDIE model, comprising analysis, design, development, implementation, and evaluation stages. Data were collected using observation, interviews, and student collaboration questionnaires, which were analyzed qualitative-descriptively and quantitatively using the N-Gain test. The validation results by material experts reached 90% categorized as "Very Valid," while media experts showed 96% categorized as "Very Valid." The media feasibility test based on teacher response achieved a score of 100% categorized as "Very Feasible." The implementation of Culture Smart Box media based on TABUDI gamification contributes to improving collaboration skills with an average N-Gain score of 0.76, which falls into the "High" category.
