Praktik pendidikan di setiap jenjang sekolah, selayaknya memenuhi tantangan abad ke-21. Literasi sains merupakan salah satu keterampilan penting yang harus dikembangkan sejak tahap awal pendidikan. Pada penelitian ini, instrumen untuk menilai keterampilan literasi biologi siswa SMP dikembangkan dan divalidasi. Pengembangan instrumen ini menerapkan tahapan model ADDIE. Instrumen ini dirancang berdasarkan kompetensi dasar IPA Biologi kurikulum 2013 untuk kelas VII, dan terdiri dari empat dimensi literasi Biologi. Dari 20 soal yang dikembangkan, terdapat 5 soal berdimensi nominal, 7 soal berdimensi fungsional, 4 soal berdimensi struktural dan 4 soal literasi biologi multidimensi. Uji validitas logis dilakukan untuk isi, konstruksi dan bahasa oleh empat validator, dan dianalisis dengan formula Aiken. Validitas empiris dilakukan dengan uji coba soal kepada 82 siswa kelas VII SMPN 3 Parung Panjang dan dianalisis menggunakan korelasi point biserial. Hasil analisis memperoleh 19 soal valid dan 1 soal tidak valid. Reliabilitas soal diuji menggunakan rumus Kuder Richardson 20, dan diperoleh nilai 0,57 yang berarti instrumen ini cukup reliabel. Tingkat kesulitan setiap soal juga dianalisis, dan diperoleh hasil dengan proporsi 70% soal memiliki tingkat kesulitan sedang dan 30% soal memiliki tingkat kesulitan tinggi.
This study aimed to improve student achievement through song-based multimedia and animated videos on viral material. This type of research is (R&D) adapting the ADDIE model. The population is class X SMA IT Baitul Qurro South Tangerang, sampling using non-probability sampling with saturated sampling technique where the entire population is a sample of 45 students. Learning achievement is measured using instruments that have been validated by experts (teachers and biology lecturers) using essays (C1- C6) for cognitive tests, questionnaires for affective tests, and observation sheets for psychomotor tests. The test was conducted before (pretest) and after (posttest) learning. Data analysis used the average score, percentage, and N-gain. The data obtained were analyzed by normality and homogeneity tests. The results obtained indicate that song-based multimedia and animated videos can improve student achievement with an average N-gain, namely: Cognitive domain of 56.8% (quite effective); The affective domain is 57% (quite effective), and the psychomotor domain is 75% (quite effective).
