Abstract

ABSTRAK Kemampuan berpikir kritis dan literasi digital merupakan kompetensi penting yang harus dimiliki peserta didik dalam menghadapi tantangan abad ke-21. Namun, dalam proses pembelajaran konvensional, kedua kemampuan tersebut masih belum optimal. Penelitian ini bertujuan untuk menganalisis pengaruh model Problem Based Learning terhadap kemampuan berpikir kritis dan literasi digital peserta didik kelas X pada mata pelajaran Biologi di SMA Negeri 1 Tanjung Bintang. Penelitian ini menggunakan pendekatan kuantitatif dengan desain quasi experimental berupa pretest-posttest control group design. Populasi penelitian berjumlah 359 peserta didik kelas X. Sampel ditentukan menggunakan teknik cluster random sampling, dengan kelas X.1 36 peserta didik sebagai kelas eksperimen yang menggunakan model Problem Based Learning, dan kelas X.2 36 peserta didik sebagai kelas kontrol yang menggunakan model Discovery Learning. Instrumen yang digunakan berupa tes berpikir kritis, angket literasi digital. Data dianalisis menggunakan uji-T Independen dengan bantuan aplikasi SPSS versi 25. Hasil penelitian menunjukkan bahwa terdapat pengaruh signifikan model Problem Based Learning terhadap kemampuan berpikir kritis dan literasi digital peserta didik. Hal ini ditunjukkan oleh nilai signifikansi < 0,05 pada kedua variabel. Dengan demikian, model Problem Based Learning terbukti efektif dalam meningkatkan kemampuan berpikir kritis dan literasi digital peserta didik kelas X pada pembelajaran Biologi.

However, these skills are often not optimally developed through conventional learning methods. This study aims to analyze the effect of the Problem Based Learning (PBL) model on students' critical thinking skills and digital literacy in Biology subjects at SMA Negeri 1 Tanjung Bintang. This research employed a quantitative approach with a quasi- experimental design using a pretest-posttest control group. The study population consisted of 359 tenth-grade students. Samples were selected using cluster random sampling, with class X.1 36 students as the experimental group implementing the Problem Based Learning model, and class X.2 36 students as the control group applying the Discovery Learning model. The instruments used were a critical thinking test and a digital literacy questionnaire. Data were analyzed using an Independent T-test with the help of SPSS version 25. The results of the study showed that the Problem Based Learning model had a significant effect on students' critical thinking and digital literacy skills. This is evidenced by significance values of < 0.05 for both variables. Therefore, the Problem Based Learning model is proven to be effective in enhancing the critical thinking and digital literacy skills of tenth-grade students in Biology learning.
