Pengaruh Model Problem Based Learning Terhadap Kemampuan Berpikir Kritis Siswa Kelas XI IPS SMA Negeri Pilangkenceng Madiun

The Effect Of Problem Based Learning Model on The Critical Thinking Abilities of The Class XI IPS  SMA Negeri Pilangkenceng Madiun

Berpikir kritis merupakan salah satu kemampuan yang harus dimiliki siswa untuk menghadapi kehidupan di abad 21. Berdasarkan wawancara diperoleh data bahwa kemampuan berpikir kritis siswa SMA Negeri Pilangkenceng masih rendah ditinjau dari nilai siswa dalam ulangan harian. Oleh sebab itu diperlukan treatmen untuk menstimuli capaian berpikir kritis pada mata pelajaran sejarah salah satunya dengan menerapkan model problem based learning.  Penelitian ini bertujuan untuk mengetahui pengaruh dan besar pengaruh model problem based learning terhadap kemampuan berpikir kritis siswa dalam pembelajaran s ejarah kelas XI IPS 1 di SMA Negeri Pilangkenceng, Madiun. Penelitian ini dilaksanakan pada semester genap tahun 2022/2023. Penelitian ini merupakan penelitian kuantitatif menggunakan metode eksperimen jenis one-shot case study design. Sampel yang digunakan adalah XI IPS 1 menggunakan teknik nonprobability sampling dengan jenis purposive sampling. Teknik pengumpulan data menggunakan metode observasi keterlaksanaan pembelajaran, pemberian tes tertulis untuk mengukur kemampuan berpikir kritis siswa dan respon siswa terhadap penerapan model pembelajaran problem based learning dan. Teknik analisa data  menggunakan uji regresi linier sederhana. Hasil penelitian sebagai berikut: (1). Keterlaksanan pembelajaran dengan model problem based learning sebesar 90% dengan kategori sangat baik. (2) Hasil tes kemampuan berpikir kritis memeroleh prosentase rata-rata sebesar 75% dengan kategori baik . (3) Respon siswa terhadap model problem based learning menunukkan 76% dengan kategori baik.  Berdasarkan hasil analisis regresi linier sederhana  diketahui nilai sig sebesar <00.1 lebih kecil dari taraf sig 0,05 dan membandingkan nilai Thitung>Ttabel dengan nilai 6.641>2.048 artinya terdapat hubungan antara kedua variabel maka Ha diterima dan H0 ditolak. Ha diterima dengan koefisien korelasi product moment sebesar 0,782 tergolong kuat dengan tingkat signifikasi <,001 maka hubungan antara dua variabel bersifat kuat. Pada model summary R Square menunjukkan 0,612 hal ini menunjukkan variabel X (model problem based learning) berpengaruh  sebesar 61,2%  terhadap variabel Y (kemampuan berpikir kritis) dengan sisanya sebesar 38,8% berasal dari variabel yang tidak diteliti dalam penelitian ini dalam penelitian ini yaitu motivasi belajar siswa dalam pembelajaran sejarah yang dimiliki oleh masing-masing individu. 

Critical thinking is one of the abilities that students must have to face life in the 21st century. Based on interviews, it was found that the critical thinking skills of Pilangkenceng State High School students are still low in terms of student scores in daily tests. Therefore, treatment is needed to stimulate the achievement of critical thinking in history subjects, one of which is by applying a problem-based learning model. This study aims to determine the influence and magnitude of the influence of the problem based learning model on students' critical thinking skills in history learning in class XI IPS 1 at SMA Negeri Pilangkenceng, Madiun. This research was carried out in the even semester of 2022/2023. This research is a quantitative study using the experimental method of the one-shot case study design type. The sample used was XI IPS 1 using a nonprobability sampling technique with purposive sampling. The data collection technique uses the observation method of learning implementation, giving written tests to measure students' critical thinking skills and students' responses to the application of problem-based learning and learning models. The data analysis technique uses a simple linear regression te. The results of the study are as follows: (1). Implementation of learning with a problem based learning model of 90% with a very good category. (2) The results of the critical thinking skills test obtained an average percentage of 75% in the good category. (3) Student responses to the problem based learning model show 76% in the good category. Based on the results of simple linear regression analysis, it is known that the sig value is <00.1 which is smaller than the sig level of 0.05 and comparing the value of Tcount>Ttable with a value of 6,641>2,048 means that there is a relationship between the two variables, so Ha is accepted and H0 is rejected. Ha is accepted with a product moment correlation coefficient of 0.782 which is classified as strong with a significance level of <.001, so the relationship between the two variables is strong. In the summary model R Square shows 0.612, this shows that variable X (problem based learning model) has an effect of 61.2% on variable Y (critical thinking skills) with the remaining 38.8% coming from variables not examined in this study in this study. this is the learning motivation of students in learning history that is owned by each individual.
