Abstract
Abstrak: Permasalahan rendahnya hasil belajar siswa menjadi titik awal penelitian ini, yang muncul akibat penerapan model pembelajaran yang kurang sesuai dengan kebutuhan peserta didik. Banyak siswa kesulitan memahami konsep sains secara konkret serta mengaitkannya dengan fenomena dalam kehidupan sehari-hari, sehingga proses pembelajaran sering terasa abstrak dan kurang bermakna. Sebagai upaya meningkatkan pencapaian akademik dan keterampilan berpikir kritis siswa, peneliti menerapkan RADEC berbasis proyek sains di kelas V SD Islam Assalam Bandar Lampung. Penelitian ini menggunakan desain quasi-eksperimen kuantitatif dengan populasi 46 siswa, yang kemudian dibagi menjadi kelas eksperimen 5A dan kelas kontrol 5B, dengan 23 siswa pada masing-masing kelas yang dipilih secara acak berdasarkan kelompok. Untuk mengukur hasil belajar, digunakan tes pilihan ganda yang telah melalui pengujian validitas dan reliabilitas. Hasil analisis uji t independen menunjukkan probabilitas 0,043, mengindikasikan adanya pengaruh signifikan RADEC dalam meningkatkan pemahaman materi, mendorong keterlibatan aktif siswa, serta memperkuat kemampuan mereka dalam mengaplikasikan konsep sains secara praktis. Kata kunci: RADEC, Projek Sains, Hasil Belajar. Abstract: The low learning achievement of students became the starting point of this study, which was caused by the implementation of an inappropriate learning model. Many students faced difficulties in understanding scientific concepts concretely and relating them to daily life. To address this issue, the researcher implemented the RADEC project based science learning model with the aim of enhancing students’ academic performance. This study specifically focused on evaluating the impact of RADEC on the learning achievement of fifth-grade students at SD Islam Assalam Bandar Lampung. A quantitative approach using a quasi experimental design was adopted, involving all 46 fifth-grade students, who were divided into two classes. The sample was determined through cluster INOVASI PEMBANGUNAN – JURNAL KELITBANGAN | VOLUME 13 NO. 2 1 http://journalbalitbangdalampung.org P-ISSN 2354-5704 | E-ISSN 2622-190X random sampling, assigning class 5A as the experimental group and class 5B as the control group, each comprising 23 students. A multiple-choice test that had been validated and confirmed for reliability served as the instrument to assess learning outcomes. Analysis using the Independent Samples t-Test revealed a significance value of 0.043, demonstrating that RADEC had a meaningful effect on students’ achievement, confirming that this learning model effectively supports students in grasping scientific concepts more thoroughly while actively participating in the learning process. Keywords: RADEC, Science Project, Learning Outcomes.
