Flipbook berbasis PBL terbukti sangat valid, praktis, dan efektif melatihkan literasi sains siswa pada topik pencemaran lingkungan

Abstract

Kompetensi literasi sains penting untuk memahami fenomena lingkungan dan pengambilan keputusan berbasis bukti, namun kegiatan pembelajaran pada materi pencemaran lingkungan masih berorientasi pada guru yang menyebabkan keterlibatan aktif murid belum optimal. Penelitian ini dilakukan dengan tujuan mengembangkan flipbook berbasis Problem Based Learning serta mengetahui validitas, kepraktisan, dan efektivitasnya dalam melatihkan kompetensi literasi sains murid kelas X SMA. Penelitian ini menggunakan metode Research and Development dengan model 4D dan melibatkan 36 murid kelas X SMA. Data diperoleh melalui validasi, observasi, angket, serta tes awal dan akhir, dengan analisis deskriptif kuantitatif yang mengacu pada persentase dan N-gain. Berdasarkan hasil analisis, flipbook yang dihasilkan mencapai tingkat validitas sebesar 99%, kepraktisan sebesar 99,3% berdasarkan angket respons murid dan 99,7% berdasarkan hasil observasi. Efektivitas media tergolong tinggi dengan N-gain sebesar 0,94 dan rata-rata ketercapaian indikator kompetensi literasi sains sebesar 96,75%. Oleh karena itu, produk flipbook berbasis PBL dinilai memiliki tingkat validitas, kepraktisan, dan efektivitas yang baik untuk melatih kompetensi literasi sains murid pada topik pencemaran lingkungan dan mendukung inovasi pembelajaran biologi sesuai tuntutan abad ke-21.

PBL-based flipbooks prove highly valid, practical, and effective in enhancing high school students' scientific literacy on environmental pollution

Abstract: Science literacy competencies competence are important for students to understand environmental phenomena and make evidence-based decisions. However, learning activities on environmental pollution are still teacher-centered, resulting in suboptimal student engagement. This study aimed to develop a Problem Based Learning-based flipbook and determine its validity, practicality, and effectiveness in fostering the scientific literacy competencies of tenth-grade high school students. This study employed the Research and Development method using the 4D model and involved 36 tenth-grade high school students. Data were collected through validation, observation, questionnaires, and pre- and post-tests, and analyzed descriptively and quantitatively based on percentages and N-gain. The results showed that the developed flipbook achieved a validity level of 99%, while its practicality reached 99.3% based on student responses and 99.7% based on observation results. The effectiveness of the media was categorized as high, with an N-gain score of 0.94 and an average achievement of scientific literacy competency indicators of 96.75%. Therefore, the PBL-based flipbook demonstrated good validity, practicality, and effectiveness in fostering students' scientific literacy competencies on the topic of environmental pollution and supporting innovation in biology learning in accordance with the demands of the 21st century.
