Abstract

INDONESIA: Latar Belakang: Kemampuan literasi sains siswa di Indonesia masih tergolong rendah yang disebabkan oleh pembelajaran yang berpusat pada guru dan kurangnya aktivitas ilmiah siswa. Pada materi klasifikasi Angiospermae, pembelajaran didominasi oleh kegiatan menghafal sehingga diperlukan bahan ajar yang dapat mendorong keaktifan siswa. Tujuan: Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan LKPD berbasis pendekatan saintifik terhadap kemampuan literasi sains siswa. Metode: Penelitian ini menggunakan pendekatan kuantitatif dengan metode kuasi eksperimen dan desain Non-Equivalent Control Group Design. Sampel diperoleh melalui cluster random sampling yang melibatkan 69 siswa, terdiri atas kelas eksperimen sebanyak 34 siswa dan kelas kontrol sebanyak 35 siswa. Instrumen yang digunakan berupa tes literasi sains, lembar observasi, dan angket respons siswa. Data dianalisis menggunakan uji N-Gain, uji Mann-Whitney, dan effect size. Hasil: Hasil penelitian menunjukkan bahwa nilai N-Gain kelas eksperimen sebesar 0,63 (sedang), sedangkan kelas kontrol sebesar 0,07 (rendah). Uji Mann-Whitney memperoleh nilai signifikansi sebesar 0,001 (<0,05) dengan effect size sebesar 0,40 (sedang), yang menunjukkan adanya pengaruh signifikan penggunaan LKPD berbasis pendekatan saintifik terhadap kemampuan literasi sains siswa. Kesimpulan: Dengan demikian, LKPD berbasis pendekatan saintifik dapat menjadi salah satu alternatif bahan ajar untuk meningkatkan kemampuan literasi sains siswa melalui pembelajaran yang aktif dan kontekstual. ENGLISH: Background: The scientific literacy skills of students in Indonesia are still relatively low due to teachercentered learning and a lack of student scientific activity. In Angiosperm classification, learning is dominated by memorization, therefore requiring active teaching materials. Objectives: This study aims to determine the effect of using scientific approach-based worksheets on students' scientific literacy skills. Method: The study used a quantitative approach with a quasi-experimental method and a NonEquivalent Control Group Design. The sample was obtained through cluster random sampling, involving 69 students, divided into experimental class (n = 34) and a control class (n = 35). Instruments used were a scientific literacy test, observation sheets, and student response questionnaires. Data were analyzed using the N-Gain test, the Mann-Whitney test, and the effect size. Result: The results showed that the N-Gain value for the experimental class was 0.63 (medium), while the control class was 0.07 (low). The Mann-Whitney test obtained a significance value of 0.001 (<0.05) with an effect size of 0.40 (medium), indicating a significant effect of using scientific approach-based worksheets on students' scientific literacy skills. Conclusion: Therefore, scientific approach-based worksheets can serve as an alternative teaching material to improve students' scientific literacy through active and contextual learning.
