Abstract

Dalam era globalisasi, keterampilan berpikir kritis menjadi keterampilan yang penting bagi peserta didik dalam menghadapi tantangan abad ke-21. Namun, studi pendahuluan menunjukkan bahwa keterampilan berpikir kritis peserta didik, khususnya pada materi fluida dinamis masih tergolong rendah akibat belum diterapkannya model pembelajaran yang optimal. Berdasarkan hasil tersebut, maka perlu diupayakan penerapan model pembelajaran yang tepat dalam meningkatkan keterampilan berpikir kritis peserta didik salah satunya adalah dengan model pembelajaran RADEC. Penelitian ini bertujuan untuk menguji efektivitas dari penerapan model pembelajaran RADEC dalam meningkatkan keterampilan berpikir kritis peserta didik pada materi fluida dinamis. Metode yang digunakan adalah pendekatan kuantitatif dengan desain Pre-Experimental dengan model One-Group Pretest-Posttest Design. Sampel penelitian terdiri dari 22 peserta didik kelas XI MIPA pada salah satu SMA di Kota Bandung, yang dipilih menggunakan teknik sampling purposive. Instrumen tes penelitian berupa 18 soal pilihan ganda untuk mengukur keterampilan berpikir kritis. Data dianalisis menggunakan perhitungan uji N-Gain, uji normalitas Shapiro-Wilik, uji Paired Sample T-Test, dan uji Wilcoxon. Hasil penelitian menunjukkan terjadi peningkatan keterampilan berpikir kritis pada peserta didik yang dilakukan treatment model pembelajaran RADEC. Setelah dilakukan treatment dengan model pembelajaran RADEC, ditemukan hasil pada nilai N-Gain sebesar 0,60 yang berada dalam kategori sedang. Hasil uji Wilcoxon menunjukkan nilai Asymp. Sig. (1-tailed) sebesar 0,000 lebih kecil dari < 0,05, maka terdapat perbedaan rata-rata antara nilai pretest dan posttest materi fluida dinamis yang menandakan model pembelajaran RADEC memberikan efektivitas terhadap peningkatan keterampilan berpikir kritis peserta didik.
In the era of globalization, critical thinking skills are important skills for students in facing the challenges of the 21st century. However, preliminary studies show that students' critical thinking skills, especially in dynamic fluid materials, are still relatively low due to the lack of implementation of an optimal learning model. Based on these results, it is necessary to apply the right learning model in improving students' critical thinking skills, one of which is the RADEC learning model. This study aims to test the effectiveness of the application of the RADEC learning model in improving students' critical thinking skills in dynamic fluid materials. The method used is a quantitative approach with a pre-experimental design in the form of a one-group pretest-posttest design. The research sample consisted of 22 students of class XI MIPA at one of the high schools in the city of Bandung, who were selected using purposive sampling techniques. The research test instrument was in the form of 18 multiple-choice questions to measure critical thinking skills. Data were analyzed using the calculation of the N-Gain test, the Shapiro-Wilik normality test, the Paired Sample T-Test, the Wilcoxon test and the effect size test. The results of the study showed that there was an increase in critical thinking skills in students who were treated by the RADEC learning model. After treatment with the RADEC learning model, the results were found at an N-Gain value of 0.60 which was in the medium category. The results of the Wilcoxon test showed that the Asymp. Sig. (1-tailed) value of 0.000 was smaller than < 0.05, so there was an average difference between the pretest and posttest values of dynamic fluid materials which indicated that the RADEC learning model was effective in improving students' critical thinking skills.
