Penelitian ini dilatarbelakangi oleh rendahnya keterampilan berpikir kritis dan motivasi belajar peserta didik dalam pembelajaran IPA. Berdasarkan observasi di SMPN 18 Banda Aceh, ditemukan bahwa sebagian besar peserta didik belum mencapai kriteria ketuntasan minimum (75), pembelajaran masih konvensional, dan keterbatasan bahan ajar. Keterampilan berpikir kritis yang rendah juga berdampak pada pemahaman konsep dan motivasi belajar. Oleh karena itu, penelitian ini bertujuan untuk menguji penerapan elektronik-lembar kerja Peserta didik berbasis Socio-Scientific Issue dalam meningkatkan keterampilan berpikir kritis dan motivasi belajar peserta didik, serta menganalisis hubungan antara kedua variabel tersebut. Penelitian menggunakan metode quasi-experiment dengan desain pretest-posttest control group design. Sampel terdiri dari dua kelas VIII, yaitu kelas eksperimen (pembelajaran dengan elektronik- lembar kerja Peserta didik berbasis Socio-Scientific Issue) dan kelas kontrol (pembelajaran konvensional). Instrumen penelitian berupa tes keterampilan berpikir kritis dan angket motivasi belajar. Data dianalisis menggunakan uji N-Gain, uji-t independen, dan uji korelasi Pearson. Hasil menunjukkan: (1) Peningkatan keterampilan berpikir kritis pada kelas eksperimen (N-Gain=0,88) signifikan dibanding kontrol (0,69); (2) Motivasi belajar kelas eksperimen meningkat sangat signifikan; (3) Terdapat hubungan positif sedang antara keterampilan berpikir kritis dan motivasi belajar (r=0,426). Disimpulkan bahwa elektronik lembar kerja Peserta didik berbasis Socio-Scientific Issue efektif meningkatkan keterampilan berpikir kritis dan motivasi belajar peserta didik dalam ilmu pengetahuan alam, serta kedua kompetensi tersebut saling terkait.

This study was motivated by the low critical thinking skills and learning motivation of students in science learning. Observations at SMPN 18 Banda Aceh revealed that most students had not met the minimum completeness criteria of 75, teaching methods remained conventional, and teaching materials were limited. Low critical thinking skills also affected conceptual understanding and learning motivation. Therefore, this research aims to examine the application of a Socio-Scientific Issue bas electronic student worksheet in improving students' critical thinking skills and learning motivation, as well as analyzing the relationship between these two variables. The study employed a quasi-experimental method with a pretest-posttest control group design. The sample consisted of two eighth-grade classes: the experimental class (taught using SSI-based electronic student worksheet) and the control class (taught using conventional methods). Research instruments included a critical thinking skills test and a learning motivation questionnaire. Data were analyzed using N-Gain test, independent t-test, and Pearson correlation analysis. The results indicated that: (1) There was a significant improvement in critical thinking skills in the experimental class (N-Gain = 0.88) compared to the control class (0.69); (2) Learning motivation in the experimental class increased very significantly; (3) There was a moderate positive correlation between critical thinking skills and learning motivation (r = 0.542). It is concluded that the Socio-Scientific Issue -based electronic student worksheet is effective in enhancing students' critical thinking skills and learning motivation in science, and that these two competencies are interrelated.
