This research is motivated by fifth-grade students' low critical thinking skills, driven by conventional one-way learning and normative teaching modules that lack local culture-based innovation. Therefore, this study aims to develop and analyze the validity, practicality, and effectiveness of a Democracy Education Teaching Module based on Meuseuraya local wisdom to enhance students' critical thinking skills. The methodology employed is Research and Development (R&D) using the ADDIE model, involving 20 fifth-grade students as field trial subjects. Data were collected through observations, questionnaires, and critical thinking tests. The results showed that the developed module met high validity criteria, scoring 95.2% with material experts, 88.2% with design experts, and 82% with linguists. Practicality reached 92% based on teacher responses and 99.8% based on student responses. Furthermore, the module improved students' critical thinking skills, as shown by classical completeness rising significantly from 67% to 85% and a moderate N-Gain score of 0.55. In conclusion, this module is highly feasible, practical, and effective for elementary school students. This study suggests that integrating local wisdom into teaching modules can foster active, context-based learning and strengthen critical thinking skills.
