Abstract


Abstract Scientific literacy about awareness and problem-solving skills related to environmental issues is one of the competencies that must be instilled in students in science learning in the future. However, teaching materials that have the potential to instill these competencies have not been easily accessed by students. The purpose of this study was to design and validate an integrated electronic module with a STEM approach on environmental pollution materials to improve problem-solving skills. This research uses Research and Development (R and D) method with ADDIE (Analysis, Design, Development, Implementation, Evaluation). The E-Module is designed for Project-Based learning (PJBL-STEM) with steps of Reflection, Research, Discovery, Application and Communication. The results of construct validation obtained a percentage of 89.4 percent, content validation yielded a percentage of 95 percent and language validation 91.7 percent with all very valid criteria. Based on the pre-test and post-test trials of the use of e-modules carried out on students, it was found that the N-gain was 0.40 with problem-solving criteria moderate for students. Overall, the research show that the developed e-module is validated with a very valid category and can improve students problem-solving skills.

Keywords e-module, STEM, PjBL, problem-solving skills.

Abstrak Literasi sains tentang kesadaran and keterampilan menyelesaikan masalah terkait isu lingkungan merupakan salah satu kompetensi yang harus ditanamkan kepada siswa dalam pembelajaran sains di masa depan. Namun, bahan ajar yang berpotensi untuk menanamkan kompetensi tersebut belum dapat diakes oleh siswa dengan mudah. Tujuan penelitian ini untuk mendesain and memvalidasi module elektronik terintegrasi pendekatan STEM pada materi pencemaran lingkungan untuk meningkatkan kemampuan pemecahan masalah. Penelitian ini menggunakan metode Research and Development dengan desain ADDIE (Analisis, Disain, Pengembangan, Implementasi, Evaluasi). E-Module dirancang untuk pembelajaran berbasis Projek (PJBL-STEM) dengan Langkah-langkah Refleksi, Melakukan penyelidikan, Menemukan informasi, Menerapkan, Mengkomunikasikan. Hasil validasi konstruk diperoleh persentase 89.4 persen, validasi isi menghasilkan persentase 95 persen and validasi bahasa 91.7 persen dengan kriteria seluruhnya sangat valid. Berdasarkan pre-test and post-test uji coba penggunaan e-module yang dilakukan pada siswa, didapatkan N-gain 0,40 dengan kriteria pemecahan masalah pada siswa yaitu seandg.  Secara keseluruhan, temuan penelitian menunjukkan bahwa e-module yang dikembangkan tervalidasi dengan kategori sangat valid and dapat meningkatkan kemampuan pemecahan masalah pada siswa.

Kata kunci modul elektronik, STEM, PjBL, kemampuan pemecahan masalah.
