Pengembangan Media Diorama Fotosintesis Project-Based Learning (PjBL) untuk Melatih Kemampuan Literasi STEM Siswa Sekolah Dasar

Penelitian ini bertujuan untuk mengembangkan media Diorama Fotosintesis yang berbasis Project Based Learning (PjBL) dan terintegrasi dengan literasi STEM yang valid, mudah digunakan, dan efektif dalam pembelajaran IPAS kelas IV. Penelitian ini menggunakan metode R&D dengan model ADDIE yang terdiri dari tahap analisis, desain, pengembangan, implementasi, dan evaluasi. Subjek penelitian adalah siswa kelas IV SDN Sidotopo IV Surabaya. Untuk mengumpulkan data, digunakan teknik validasi dari ahli, angket respons siswa, wawancara guru, serta tes hasil belajar. Hasil penelitian menunjukkan bahwa media Diorama Fotosintesis memperoleh persentase kevalidan sebesar 86,92% dengan kategori sangat valid. Kepraktisan media ditunjukkan melalui respons siswa yang mencapai 86,04% dengan kategori sangat praktis. Keefektifan media terlihat dari ketuntasan belajar sebesar 91,7% yang melebihi standar minimal. Berdasarkan hasil tersebut, media Diorama Fotosintesis berbasis PjBL-STEM dianggap layak, praktis, dan efektif digunakan sebagai media pembelajaran pendukung IPAS di sekolah dasar.

This research aims to develop Project-Based Learning (PjBL) Photosynthesis Diorama media integrated with STEM literacy that is valid, easy to use, and effective in fourth-grade science learning. This research employed the R&D method with the ADDIE model, which consists of analysis, design, development, implementation, and evaluation stages. The subjects were fourth-grade students of SDN Sidotopo IV Surabaya. Data collection included expert validation, student response questionnaires, teacher interviews, and learning outcome tests. The results showed that the Photosynthesis Diorama media achieved a validity percentage of 86.92%, categorized as very valid. The media’s practicality was demonstrated by student responses, which reached 86.04%, categorized as very practical. The media’s effectiveness was evident in the learning completion rate of 91.7%, exceeding the minimum standard. Based on these results, the PjBL-STEM-based Photosynthesis Diorama media is considered feasible, practical, and effective as a supporting learning medium for science in elementary school.
