ABSTRAK

      Pendidikan abad XXI menekankan pada kemampuan berpikir tingkat tinggi salah satunya adalah berpikir kritis. Berpikir kritis merupakan pola berpikir yang penting, dengan berpikir kritis seseorang akan mampu menganalisis dan menemukan kebenaran permasalahan yang terjadi disekitarnya. Kemampuan berpikir kritis juga dipengaruhi oleh proses belajar mengajar yang dilakukan oleh guru didalam kelas. Proses pembelajaran yang dilakukan di SMA Negeri Kabuh, Jombang kurang memfasilitasi siswa untuk mendorong kemampuan berpikir kritis mereka. Hal ini dikarenakan ketika proses belajar mengajar didalam kelas, guru masih menggunakan metode belajar yang konvensional. Kurangnya kemampuan berpikir kritis siswa ini ditandai dengan lemahnya siswa dalam mengemukakan ide atau gagasan dan siswa belum mampu mengajukan pertanyaan yang menunjukkan proses berpikir kritis.

         Berdasarkan permasalahan yang terjadi di SMA Negeri Kabuh, Jombang tersebut peneliti menerapkan salah satu model pembelajaran yang mampu mendorong kemampuan berpikir kritis siswa yaitu model pembelajaran project based learning. Desain yang digunakan didalam penelitian ini adalah Pre Experimental Design, sampel dalam penelitian ini adalah siswa kelas XI IPS SMA Negeri Kabuh. Teknik pengumpulan data berupa rata- rata penilaian proyek/ produk “History Mading”, tes kemampuan berpikir kritis siswa, lembar observasi, dan angket respon siswa. Teknik analisis data yang digunakan adalah analasis hasil penilaian proyek “History Mading”, dan analisis tes kemampuan berpikir kritis siswa berupa soal essay. Penelitian ini bertujuan untuk (1) Menjelaskan  pengaruh model pembelajaran project based learning terhadap kemampuan berpikir kritis siswa pada mata pelajaran sejarah ; (2) Untuk menganalisis besar pengaruh model pembelajaran project based learning terhadap kemampuan berpikir kritis siswa pada mata pelajaran sejarah.

     Hasil penelitian dengan menggunakan uji regresi linier sederhana menghasilkan persamaan regresi Y = 19, 049+ 0,718 X. Koefisien regresi menunjukkan nilai yang positif hal ini berarti model pembelajaran project based learning berpengaruh terhadap kemampuan berpikir kritis siswa. Selain itu dari pengujian dengan uji regresi liner sederhana diperoleh nilai signifikasi 0,000 < taraf signifikasi 0.05 dan T hitung sebesar 6,825  > T tabel yakni  2,042 maka dapat disimpulkan bahwa model pembelajaran project based learning berpengaruh terhadap kemampuan berpikir kritis siswa. Koefisien determinasi pada uji regresi linier sederhana menunjukkan angka 60,8 yang memiliki makna bahwa besar pengaruh model pembelajaran project based learning terhadap kemampuan berpikir kritis siswa adalah 60,8 %.

The XXI century education emphasizes on a high-level thinking skills, one of which is critical thinking. Critical thinking is an important pattern of thinking whereas critical thinking makes someone will be able to analyze and find out the truth of the problems that occur around. The ability to think critically is also influenced by the teaching and learning process carried out by the teacher in the classroom. The learning process carried out in Kabuh State High School, Jombang does not facilitate students to encourage their critical thinking skills. This is because when the learning process occurs in the classroom, the teacher still uses conventional learning methods. The lack of critical thinking skills of students is characterized by the weakness of students in expressing ideas or insights and students have not been able to ask questions that show the process of critical thinking.

Based on the problems that occur in Kabuh State High School, Jombang, the researcher applied one of the learning models that was able to encourage students' critical thinking skills, namely the project based learning model. The design used in this study was Pre Experimental Design, the sample in this study were XI IPS class students of Kabuh State High School. Data collection techniques were in the form of the average assessment of projects / products "History Mading", tests of students' critical thinking skills, observation sheets, and student response questionnaires. The data analysis technique used was the analysis of the results of the "History Mading" project evaluation, and analysis of the test of students' critical thinking skills in the form of essay questions. This study aims to (1) Explain the effect of project based learning models on students' critical thinking skills in historical subjects; (2) To analyze the influence of the project based learning model on students' critical thinking skills in historical subjects.

The results of the study using simple linear regression test resulted in a regression equation Y = 19, 049+ 0.718 X. The regression coefficient shows a positive value, means that the project based learning model influences students' critical thinking skills. In addition, from testing with a simple linear regression test,it was obtained a significance value of 0,000 <significance level of 0.05 and T arithmetic of 6,825> T table that is 2, 042, it can be concluded that the project based learning model influences students' critical thinking skills. The coefficient of determination in a simple linear regression test shows the number 60.8 which means that the influence of the project based learning model on students' critical thinking skills is 60.8%.
