Abstract

Peserta didik sering mengalami kesulitan dalam memahami materi listrik pada pembelajaran IPA dan belum menunjukkan kemampuan berpikir kritis secara optimal. Masalah ini muncul karena model pembelajaran yang digunakan belum memberi ruang eksplorasi yang cukup. Penelitian ini bertujuan untuk mengetahui efektivitas model Project Based Learning (PjBL) terhadap kemampuan berpikir kritis siswa kelas V SD pada materi listrik. Penelitian menggunakan pendekatan kuantitatif dengan desain quasi eksperimen tipe nonequivalent control group design. Subjek penelitian terdiri dari dua kelas, yaitu kelas kontrol yang mendapat pembelajaran konvensional, dan kelas eksperimen yang menerapkan model PjBL. Instrumen yang digunakan berupa soal uraian dan pilihan ganda untuk mengukur kemampuan berpikir kritis sebelum dan sesudah perlakuan. Analisis data dilakukan menggunakan teknik nonparametrik, meliputi uji normalitas, homogenitas, uji Mann-Whitney, dan perhitungan N-Gain. Hasil penelitian menunjukkan bahwa kelas eksperimen mengalami peningkatan signifikan dalam kemampuan berpikir kritis, baik pada soal uraian maupun pilihan ganda, dibandingkan dengan kelas kontrol yang peningkatannya cenderung lebih rendah. Temuan ini membuktikan bahwa model PjBL efektif digunakan untuk meningkatkan kemampuan berpikir kritis peserta didik pada materi listrik. Students often face difficulties in understanding the topic of electricity in science learning and have not demonstrated optimal critical thinking skills. This issue arises due to the learning model used, which does not provide sufficient opportunities for exploration. This study aims to determine the effectiveness of the Project Based Learning (PjBL) model on the critical thinking skills of fifth-grade elementary school students in the topic of electricity. The research employs a quantitative approach with a quasi-experimental design of the nonequivalent control group type. The subjects consist of two classes: a control class receiving conventional instruction, and an experimental class implementing the PjBL model. The instruments used are essay and multiple-choice questions to measure students' critical thinking skills before and after the treatment. Data analysis was conducted using non-parametric techniques, including normality tests, homogeneity tests, the Mann-Whitney test, and N-Gain calculation. The results show that the experimental class experienced a significant improvement in critical thinking skills, both in essay and multiple-choice questions, compared to the control class, which showed relatively lower improvement. These findings indicate that the PjBL model is effective in enhancing students' critical thinking skills in the topic of electricity.
