PENGEMBANGAN BAHAN AJAR CLUSTER-BLENDED LEARNING UNTUK MENINGKATKAN LITERASI SAINS SISWA PADA MATERI REDOKS

Development Of Cluster-Blended Learning Teaching Materials To Improve Student's Science Literature On Redox Material.

Penelitian ini bertujuan untuk mendeskripsikan kelayakan bahan ajar (silabus, Rencana Pelaksanaan Pembelajaran (RPP), Unit Kegiatan Belajar Mandiri (UKBM) dan kisi-kisi soal pretest-posttest) Cluster-blended learning untuk pembelajaran kimia pada materi reaksi oksidasi reduksi untuk kelas X IPA SMA. Validitas, kepraktisan dan keefektifan digunakan untuk menggambarkan kelayakan bahan ajar. Hasil analisis data validitas, kepraktisan, dan keefektifan menunjukkan bahwa bahan ajar yang dikembangkan memenuhi syarat dengan persentase reliabilitas lebih dari 75%. Oleh karena itu, bahan ajar Cluster-blended learning dinyatakan memenuhi kriteria validitas, praktis, efektifitas dalam kategori tinggi. Implikasinya, layak digunakan sebagai bahan ajar reaksi oksidasi reduksi untuk meningkatkan literasi sains siswa.

This study aims to describe the feasibility of teaching material (syllabus, Lesson Plans (RPP), Independent Learning Activity Unit (UKBM) and pretest-posttest question grid) of cluster-blended learning based on reduction oxidation reactions for class X science high school chemistry learning. Validity, practicality and effectiveness were used to describe the teaching material’s feasibility. Data analysis of validity, practicality, and effectiveness results showed that. The teaching materials developed are eligible with a percentage of agreement more than 75%. Therefore, cluster-blended learning teaching materials are declared to meet the validity, practical, effectiveness criteria in high category. As implication, it is feasible to use as teaching materials of reduction oxidation reactions to improve students’ scientific literacy.
