Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh model pembelajaran RADEC (Read, Answer, Discuss, Explain, Create) terhadap kemampuan berpikir kritis siswa kelas V SD pada materi Perubahan Kondisi Alam yang terintegrasi dengan Sustainable Development Goals (SDGs), serta membandingkan perbedaan kemampuan berpikir kritis antara siswa laki-laki dan perempuan. Metode penelitian yang digunakan adalah kuantitatif dengan desain quasi experimental, melibatkan dua kelas paralel di SDN Haurpugur 02, Bandung. Kelas VA sebagai kelompok eksperimen (n=27) menggunakan model RADEC, sedangkan kelas VB sebagai kelompok kontrol (n=27) menggunakan Problem Based Learning (PBL). Instrumen penelitian berupa tes uraian pretest–posttest berbasis indikator berpikir kritis Ennis, lembar observasi, dan angket respon siswa. Hasil penelitian menunjukkan adanya peningkatan signifikan kemampuan berpikir kritis pada kelas eksperimen (rata-rata posttest = 82,7) dibandingkan kelas kontrol (rata-rata posttest = 61,2). Analisis juga mengungkap tidak terdapat perbedaan signifikan antara siswa laki-laki dan perempuan dalam peningkatan kemampuan berpikir kritis. Temuan ini menegaskan bahwa RADEC efektif meningkatkan kemampuan berpikir kritis siswa melalui tahapan literasi awal, diskusi kolaboratif, komunikasi, dan kreasi produk yang kontekstual dengan isu lingkungan. Penelitian ini merekomendasikan penerapan RADEC pada pembelajaran IPAS untuk mendorong literasi kritis dan kesadaran keberlanjutan sejak sekolah dasar. ------------ This study aims to analyze the effect of the RADEC (Read, Answer, Discuss, Explain, Create) learning model on the critical thinking skills of fifth-grade elementary school students in the topic Environmental Changes, which is integrated with the Sustainable Development Goals (SDGs), as well as to compare the differences in critical thinking skills between male and female students. The research method employed was quantitative with a quasi-experimental design, involving two parallel classes at SDN Haurpugur 02, Bandung. Class VA served as the experimental group (n=27) using the RADEC model, while Class VB served as the control group (n=27) using Problem-Based Learning (PBL). The research instruments included pretest–posttest essay tests based on Ennis’s critical thinking indicators, observation sheets, and student response questionnaires. The results revealed a significant improvement in critical thinking skills in the experimental class (posttest mean = 82.7) compared to the control class (posttest mean = 61.2). The analysis also indicated no significant difference between male and female students in terms of improvement in critical thinking skills. These findings confirm that RADEC is effective in enhancing students’ critical thinking skills through stages of initial literacy, collaborative discussion, communication, and product creation contextualized with environmental issues. This study recommends the implementation of RADEC in science and social studies learning (IPAS) to foster critical literacy and sustainability awareness from the elementary school level.
