Abstract

Hasil asesmen PISA tahun 2018 menunjukkan bahwa literasi sains siswa Indonesia berada pada level rendah, dengan skor 396, menempatkan Indonesia di posisi ke-70 dari 79 negara. Penyebabnya karena pendekatan pembelajaran yang teacher-centered dan kurang kontekstual. Pembelajaran berbasis student-centered learning, seperti model RADEC (Read, Answer, Discuss, Explain, and Create) telah terbukti meningkatkan literasi sains. Namun, penelitian terdahulu tentang RADEC belum memadukan konteks budaya lokal seperti etnosains, yang dapat membuat pembelajaran lebih relevan, sehingga penelitian ini bertujuan: (1) mengukur kemampuan literasi sains siswa sebelum dan setelah penerapan model RADEC berbasis etnosains Kampung Naga, (2) mengidentifikasi kategori siswa yang mengalami perubahan signifikan, (3) menganalisis aspek literasi sains yang paling terdampak, dan (4) menguji efektivitas model. Penelitian menggunakan metode pre-eksperimen dengan desain one group pretest-posttest, melibatkan 25 siswa kelas V SD di Kota Tasikmalaya. Data dikumpulkan melalui tes literasi sains berbasis etnosains dan observasi keterlaksanaan pembelajaran. Analisis data dilakukan dengan Model Rasch (stacking-racking), uji normalitas Shapiro-Wilk, dan uji hipotesis Wilcoxon. Hasil menunjukkan perubahan signifikan kemampuan literasi sains siswa dengan selisih nilai logit 2,67 dari -0,94 (pretest) menjadi 1,73 (posttest). Perubahan signifikan terjadi pada kelompok siswa yang sebelumnya memiliki kemampuan rendah. Selisih logit butir soal sebesar 2,48 menunjukkan penurunan kesulitan soal setelah intervensi. Aspek literasi sains yang menunjukkan perubahan paling tinggi adalah aspek mengevaluasi dan merancang penyelidikan ilmiah. Uji Wilcoxon (Asymp. Sig. = 0,000; p < 0,05) menunjukkan perbedaan signifikan antara pre-postestt, membuktikan efektivitas model RADEC berbasis etnosains. Temuan ini mendukung penggunaan pendekatan kontekstual dalam pembelajaran IPA untuk mengatasi tantangan literasi sains di Indonesia. The 2018 PISA assessment results indicate that Indonesian students' science literacy is at a low level, with a score of 396, ranking Indonesia in 70th position out of 79 countries. This is due to the teacher-centered learning approach and lack of contextualization. Student-centered learning, such as the RADEC (Read, Answer, Discuss, Explain, and Create) model, has been shown to improve science literacy. However, previous research on RADEC has not integrated local cultural contexts such as ethnoscience, which can make learning more relevant. So this study aims to: (1) measure students' science literacy skills before and after the application of the Kampung Naga ethnoscience-based RADEC model, (2) identify categories of students who experience significant changes, (3) analyze the most affected aspects of science literacy, and (4) test the effectiveness of the model. The research used a pre-experiment method with a one-group pretest-posttest design, involving 25 fifth-grade students in Tasikmalaya City. Data were collected through ethnoscience-based science literacy tests and observations of learning implementation. Data analysis was conducted with the Rasch Model (stacking-racking), Shapiro-Wilk normality test, and Wilcoxon hypothesis test. The results showed a significant increase in students' science literacy skills with a logit value difference of 2.67 from -0.94 (pretest) to 1.73 (posttest). Significant improvement occurred in the group of students who previously had low ability. The logit difference of the items of 2.48 indicates a decrease in the difficulty of the questions after the intervention. The aspects of science literacy that showed the highest improvement were the aspects of evaluating and designing scientific investigations. The Wilcoxon test (Asymp. Sig. = 0.000; p < 0.05) showed a significant difference between the pre- and post-tests, proving the effectiveness of the ethnoscience-based RADEC model. These findings support the use of contextualized approaches in science learning to address science literacy challenges in Indonesia.
