<![CDATA[The limited availability of interactive digital learning materials in Science and Social Studies (IPAS) often causes student disengagement and difficulties in comprehending Indonesian cultural diversity, necessitating the development of structured and innovative instructional media. This research and development study aimed to produce a scientific approach-based e-module on the "Indonesiaku Kaya Budaya" topic for fourth-grade students of SDN 17 Muara Padang that is valid and practical for learning. This study employed the Research and Development (R&D) method using the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The research was conducted during the second semester of the 2025/2026 academic year, involving 3 expert validators (media, language, and subject matter) and 25 fourth-grade students (3 students for the one-to-one trial and 22 students for the small-group trial). Data analysis revealed that the developed e-module was categorized as "very valid" with validation scores of 85.71% from media experts, 93.33% from language experts, and 88.00% from subject matter experts, yielding an overall average of 89.01%. Practicality testing resulted in 93.33% in the one-to-one trial (very practical) and 97.86% in the small-group trial (very practical). In conclusion, the scientific approach-based e-module is proven to be highly valid and practical, making it suitable for instructional use in primary school IPAS learning. ABSTRAK Keterbatasan bahan ajar digital interaktif dalam pembelajaran IPAS menyebabkan peserta didik mengalami kejenuhan dan kesulitan dalam memahami materi keberagaman budaya Indonesia, sehingga diperlukan pengembangan media ajar yang inovatif dan terstruktur. Penelitian dan pengembangan ini bertujuan untuk menghasilkan e-modul berbasis pendekatan saintifik pada materi Indonesiaku Kaya Budaya kelas IV SDN 17 Muara Padang yang valid dan praktis digunakan dalam proses pembelajaran. Penelitian ini menggunakan metode Research and Development (R&D) dengan model pengembangan ADDIE (Analysis, Design, Development, Implementation, Evaluation). Subjek penelitian dilaksanakan pada semester genap Tahun Ajaran 2025/2026 yang melibatkan 3 orang validator ahli (ahli media, bahasa, materi) serta 25 peserta didik kelas IV (3 peserta didik pada uji one-to-one dan 22 peserta didik pada uji small group). Hasil analisis data menunjukkan bahwa e-modul yang dikembangkan termasuk dalam kategori sangat valid berdasarkan validasi ahli media sebesar 85,71%, ahli bahasa sebesar 93,33%, dan ahli materi sebesar 88,00%, dengan rata-rata kevalidan sebesar 89,01%. Tingkat kepraktisan e-modul menunjukkan persentase 93,33% pada uji one-to-one (sangat praktis) dan 97,86% pada uji small group (sangat praktis). Dengan demikian, e-modul berbasis pendekatan saintifik materi Indonesiaku Kaya Budaya terbukti sangat valid dan sangat praktis sehingga layak digunakan sebagai sumber belajar mandiri maupun klasikal dalam pembelajaran IPAS di sekolah dasar. ]]>
