Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh model Problem Based Learning (PBL) terhadap berpikir kritis siswa pada materi Persebaran Flora dan Fauna di Dunia dan Indonesia Kelas XI SMA Negeri 58 Jakarta. Jenis penelitian yang digunakan adalah quasi experiment dengan metode deskriptif kuantitatif. Populasi dan sampel penelitian ini adalah kelas XI-1 sebagai kelas eksperimen dan XI-2 sebagai kelas kontrol dengan jumlah siswa masing-masing adalah 36 orang. Teknik pengumpulan data dalam penelitian ini adalah purpossive sampling. Instrumen yang digunakan adalah tes uraian dan angket persepsi siswa. Teknik analisis data berupa uji normalitas, homogenitas, linearitas, dan analisis regresi linear sederhana. Hasil penelitian diperoleh nilai N-Gain Score adalah 0,4327 yang termasuk kriteria sedang dengan persentase 42,37% yang berarti kurang efektif dengan tingkat sedang. Hasil uji regresi linear sederhana, yaitu Y = 39,855 + 0,370X. Artinya, jika penerapan model PBL (X) bertambah satu satuan maka nilai kemampuan berpikir kritis (Y) mengalami peningkatan sebanyak 37%. Sedangkan untuk koefisien determinasi hanya sebesar 0,113. Artinya dalam penelitian ini, model Problem Based Learning (PBL) memiliki pengaruh yang lemah terhadap kemampuan berpikir kritis siswa. Pengaruh model Problem Based Learning (PBL) terhadap kemampuan berpikir kritis siswa hanya 11,3% dan sisanya dipengaruhi oleh faktor lain. ***** This study aims to determine the effect of the Problem Based Learning (PBL) model on students' critical thinking on the material of the Distribution of Flora and Fauna in the World and Indonesia of Class XI of SMA Negeri 58 Jakarta. The type of research used is a quasi-experiment with a quantitative descriptive method. The population and sample of this study were class XI-1 as the experimental class and XI-2 as the control class with the number of students each being 36 people. The data collection technique in this study was purposive sampling. The instruments used were essay tests and student perception questionnaires. Data analysis techniques were in the form of normality, homogeneity, linearity, and simple linear regression analysis. The results of the study obtained an N-Gain Score of 0.4327 which is included in the medium criteria with a percentage of 42.37% which means it is less effective with a medium level. The results of the simple linear regression test, namely Y = 39.855 + 0.370X. This means that if the application of the PBL model (X) increases by one unit, the value of critical thinking ability (Y) increases by 37%. While the coefficient of determination is only 0.113. This means that in this study, the Problem-Based Learning (PBL) model had a weak influence on students' critical thinking skills. The effect of the Problem-Based Learning (PBL) model on students' critical thinking skills was only 11.3%, with the remainder influenced by other factors.
