PENGARUH MODEL PBL TERHADAP KEMAMPUAN BERPIKIR KRITIS DAN AKTIVITAS BELAJAR SISWA
Get PDFThis research aimed to determine the influence of PBL model towards critical thinking and students learning activity. The sample of this research were students of VIIB and VIID SMP Nusantara Bandar Lampung that were chosen by Purposive Sampling technique. The research used pretest-posttest non equivalent design. The quantitative data were obtained from the critical thinking improvement that was analyzed by using T-Test and U-Test. The qualitative data were gained from students observation sheet and student responses about PBL model. The result showed that critical thinking in experiment class with N-gain average (46,18) was significantly different with class control (36,95). Students activity in problem identification, argumentation, induction, and deduction were in average criteria. While the evaluation activity was in low criteria. Therefore, PBL influenced critical thinking and students learning activity on the material of environmentals management.Penelitian ini bertujuan mengetahui pengaruh model PBL terhadap kemampuan berpikir kritis dan aktivitas belajar siswa.
