Abstract

This study explores the analytical thinking skills of prospective Madrasah Ibtidaiyah (MI) teacher students in understanding seasonal changes in Lampung through the ethnoscience-based RADEC learning model integrated with the local Ngumbai Sabah tradition. The aim is to bridge scientific concepts with local wisdom through both verbal and visual representations.The research employed a quantitative experimental design with a One-Pretest–Posttest design. The sample consisted of PGMI students from Class H, and the instrument was an open-ended essay test assessing students’ abilities to differentiate, organize, connect concepts, and present them visually. Data were analyzed descriptively and inferentially, including a paired-sample t-test to evaluate the effectiveness of RADEC.Results show that the ethnoscience-based RADEC model effectively improves students’ ability to differentiate and organize concepts. However, their ability to connect concepts comprehensively remains limited, especially in visual representations. The main hindering factors are misconceptions regarding basic science concepts, particularly seasonal change phenomena, and difficulties in representing the relationships between scientific concepts and Lampung’s local wisdom. Most visual outputs remain descriptive and fragmented, highlighting the need to strengthen higher-order analytical thinking skills and visual literacy.

Abstract

Pendidikan abad ke-21 menuntut siswa sekolah dasar memiliki kemampuan berpikir tingkat tinggi Higher Order Thinking Skills (HOTS) agar mampu memahami, menganalisis, dan menyelesaikan berbagai permasalahan secara kritis dan kreatif. Namun, kemampuan HOTS siswa sekolah dasar masih memerlukan penguatan untuk mendukung keterlibatan siswa secara aktif dan bermakna dalam proses pembelajaran. Penelitian ini bertujuan untuk menganalisis pengaruh integrasi Deep Learning dalam model Problem Based Learning (PBL) terhadap kemampuan HOTS siswa pada pembelajaran IPAS. Penelitian menggunakan pendekatan kuantitatif dengan desain quasi experiment nonequivalent control group design yang melibatkan 53 siswa kelas V SD Al Azhar 1 Bandar Lampung. Data dikumpulkan melalui tes HOTS berbentuk pilihan ganda beralasan dan dianalisis menggunakan statistik deskriptif, Independent Sample t-Test, dan N-Gain. Hasil penelitian menunjukkan bahwa rata-rata nilai posttest kelas eksperimen (78,26) lebih tinggi dibandingkan kelas kontrol (72,27). Hasil uji hipotesis memperoleh nilai signifikansi 0,003 (<0,05), sedangkan nilai N-Gain kelas eksperimen (0,41) lebih tinggi dibandingkan kelas kontrol (0,20). Sejalan dengan itu, integrasi Deep Learning dalam model PBL berpengaruh terhadap kemampuan HOTS siswa dan dapat menjadi alternatif pembelajaran untuk mendukung pengembangan kemampuan berpikir tingkat tinggi pada pembelajaran IPAS.
