PENERAPAN MODEL PEMBELAJARAN READ, ANSWER, DISCUSS, EXPLAIN, AND CREATE (RADEC) UNTUK MENINGKATKAN KETERAMPILAN BERPIKIR KRITIS SISWA SMP PADA MATERI GETARAN

THE IMPLEMENTATION OF THE READ, ANSWER, DISCUSS, EXPLAIN, AND CREATE (RADEC) LEARNING MODEL TO IMPROVE JUNIOR HIGH SCHOOL STUDENTS' CRITICAL THINKING SKILLS ON THE TOPIC OF VIBRATION

Penelitian ini dilatarbelakangi oleh rendahnya keterampilan berpikir kritis siswa SMP, yang tercermin dalam hasil PISA 2022 di mana Indonesia menempati peringkat 67 dari 81 negara dengan skor di bawah rata-rata global. Penelitian ini bertujuan untuk mendeskripsikan (1) keterlaksanaan proses pembelajaran Read, Answer, Discuss, Explain, and Create (RADEC); (2) peningkatan keterampilan berpikir kritis siswa SMP dengan penerapan model Read, Answer, Discuss, Explain, and Create (RADEC); (3) respons siswa terhadap penerapan model pembelajaran Read, Answer, Discuss, Explain, and Create (RADEC). Penelitian ini menggunakan rancangan pre-experimental design dengan desain one-group pretest-posttest. Penelitian ini dilakukan di SMP Negeri 54 Surabaya dengan subyek penelitian yaitu kelas VIII A yang ditentukan menggunakan teknik purposive sampling. Teknik pengumpulan data menggunakan observasi, tes, dan kuesioner. Hasil tes dianalisis menggunakan N-gain (Normalized Gain) dan uji-t berpasangan. Hasil penelitian menunjukkan bahwa keterampilan berpikir kritis siswa menunjukkan peningkatan setelah model pembelajaran RADEC diimplementasikan dan terdapat perbedaan signifikan pada peningkatan keterampilan berpikir kritis sebelum dan sesudah adanya pembelajaran RADEC.

This study is motivated by the low critical thinking skills of junior high school students, which is reflected in the PISA 2022 results where Indonesia ranks 67 out of 81 countries with a score below the global average. This study aims to describe (1) the implementation of the Read, Answer, Discuss, Explain, and Create (RADEC) learning process; (2) the improvement of critical thinking skills of junior high school students with the application of the Read, Answer, Discuss, Explain, and Create (RADEC) model; (3) student responses to the application of the Read, Answer, Discuss, Explain, and Create (RADEC) learning model. This research used pre-experimental design with one-group pretest-posttest design. This research was conducted at SMP Negeri 54 Surabaya with the research subjects being class VIII A which was determined using purposive sampling technique. Data collection techniques used observation, tests, and questionnaires. The test results were analysed using N-gain (Normalised Gain) and paired t-test. The results showed that students' critical thinking skills showed improvement after the RADEC learning model was implemented and there was a significant difference in the improvement of critical thinking skills before and after RADEC learning.
