Abstract
Penelitian ini bertujuan untuk mengetahui peningkatan keterampilan berpikir kritis peserta didik setelah diterapkannya pembelajaran dengan Strategi REACT berbantuan PhET Simulation. Metode penelitian yang digunakan adalah kuantitatif dengan desain penelitian yang digunakan yaitu pre-experimental design berbentuk one group pretest-posttest design. Populasi penelitian ini adalah seluruh peserta didik kelas XI di salah satu SMA Kota Bandung. Sampel penelitian ini diperoleh meggunakan teknik purposive sampling, melibatkan 55 peserta didik kelas XI-2 yang akan mengikuti pembelajaran karakteristik gelombang mekanik. Instrumen yang digunakan adalah tes keterampilan berpikir kritis berbentuk esai yang berjumlah 8 butir soal, Lembar Kerja Peserta Didik (LKPD), lembar observasi keterlaksanaan pembelajaran, dan angket respon peserta didik. Teknik analisis data yang digunakan adalah persentase, N-Gain, dan effect size. Hasil penelitian peningkatan keterampilan berpikir kritis peserta didik pada penerapan Strategi REACT berbantuan PhET Simulation menunjukkan N Gain sebesar 0,52 yang dapat dikategorikan ke dalam kategori sedang. Selain itu, didapat bahwa penerapan Strategi REACT berbantuan PhET Simulation efektif untuk meningkatkan keterampilan berpikir kritis peserta didik dengan d value sebesar 3,19 termasuk ke dalam kategori tinggi. Dapat disimpulkan bahwa penerapan Strategi REACT berbantuan PhET Simulation dapat meningkatkan keterampilan berpikir kritis peserta didik SMA pada materi karakteristik gelombang mekanik.
This study aims to determine the improvement of students' critical thinking skills after implementing the REACT Strategy assisted by PhET Simulation. The research method used is quantitative, with a pre-experimental design in the form of a one group pretest-posttest design. The population of this study consists of all 11th-grade students at a high school in Bandung. The research sample was obtained using purposive sampling, involving 35 students from class XI-2 who participated in learning about the characteristics of mechanical waves. The instruments used include an essay based critical thinking skills test consisting of eight questions, Student Worksheets (LKPD), an observation sheet on the implementation of learning, and a student response questionnaire. The data analysis techniques used are percentage analysis, N-Gain, and effect size. The results of the study show that the improvement in students' critical thinking skills through the implementation of the REACT Strategy assisted by PhET Simulation yielded an N-Gain of 0.52, which falls into the moderate category. Additionally, it was found that the application of the REACT Strategy assisted by PhET Simulation was effective in enhancing students' critical thinking skills, with a d-value of 3.19, classified as high. It can be concluded that the implementation of the REACT Strategy assisted by PhET Simulation can improve high school students' critical thinking skills in learning about the characteristics of mechanical waves.
