PENGARUH MODEL PEMBELAJARAN PROBLEM BASED LEARNING TERHADAP PENINGKATAN KEMAMPUAN BERPIKIR KRITIS SISWA
The purpose of this study to determine the effect of PBL models to increase student’s critical thinking skills and learning activities at class X SMA Negeri 3 Kotabumi in Environment subject matter. The research design was pretest-posttest equivalent groups.The samples were X5 and X3 class which selected by purposive sampling.Quantitative data obtained from the average of pretest, posttest, and N-Gain were statistically analyzed using u-test.Qualitative data in the form of student’s activities. The results showed that there are no significant effect improving student’s critical thinking skills with using PBL models, it’s seen in average N-gain of experiment 32.13 and control 30.54 . But the average of all student’s activities in PBL models class was higher each meeting.It’s can be concluded that the use of the PBL models can’t significant improve critical thinking skills but it can improve student’s activities in environment subject matter. Tujuan penelitian ini untuk mengetahui pengaruh model PBL terhadap peningkatan kemampuan berpikir kritis dan aktivitas belajar siswa kelas X SMA Negeri 3 Kotabumi pada materi pokok Lingkungan. Desain penelitian adalah pretes-postes kelompok equivalen. Sampel adalah siswa kelas X5 dan X3 yang dipilih dengan teknik purposive sampling. Data kuantitatif diperoleh dari rata-rata nilai pretes, postes, dan N-Gain yang dianalisis secara statistik menggunakan uji-u. Data kualitatif berupa data aktivitas belajar siswa selama proses pembelajaran. Hasil penelitian menunjukkan bahwa penggunaan model PBL berpengaruh tidak signifikan dalam meningkatkan kemampuan berpikir kritis siswa, ini terlihat rata-rata nilai N-gain pada kelas eksperimen sebesar 32,13 dan kelas kontrol sebesar 30,54. Namun hasil rata-rata keseluruhan aktivitas siswa pada kelas yang menggunakan model pembelajaran PBL dinyatakan tinggi setiap pertemuannya.

Mastery of concepts that are not quite optimal by high school science students of class IX N 2 Metro affected by the lack of proper strategies in the learning process. Strategies that can facilitate student achievement and skill one is mind mapping. Using mind mapping aims to determine students' critical thinking skills. Experimental research design was pretest-posttest form is not equivalent to involve XI IPA1 as the experimental class and control class XI IPA2 as selected by purposive sampling technique. The research data in the form of qualitative data obtained from students 'learning activities are analyzed using an index of students' critical thinking skills and mind mapping products derived from each group discussions and quantitative data obtained from a pretest-posttest were analyzed using t-test. The results showed improvement in the experimental class students' mastery of concepts with an average gain of 64.73 N-higher than the average N-gain the control class is 47.52. The average increase in each indicator of cognitive mastery of concepts by students in the experimental class also higher at 41.27 while the control class is 31.55. Similarly, student learning activities, that the experimental class achieving increased higher activity than the control class. Aspects express opinions / ideas and discuss work on LKS is the highest activity obtained by the students. Based on the achievements that have been disclosed, it can be concluded that the mind mapping is effective in improving students' critical thinking skills.
