Penelitian ini bertujuan untuk (1) mendeskripsikan kemampuan berpikir kritis siswa kelompok eksperimen yang belajar menggunakan model pembelajaran berbasis proyek, (2) mendeskripsikan kemampuan berpikir kritis siswa kelompok kontrol yang belajar dengan model pembelajaran konvensional, (3) mengetahui perbedaan yang signifikan kemampuan berpikir kritis antara kelompok siswa yang belajar dengan model pembelajaran berbasis proyek dan kelompok siswa yang belajar dengan model pembelajaran konvensional dalam pembelajaran IPA di kelas V SD di Gugus IV Kecamatan Buleleng. Jenis penelitian ini adalah penelitian eksperimen semu dengan rancangan non-equivalent post test only control group design. Populasi penelitian adalah seluruh siswa kelas V SD di Gugus IV Kecamatan Buleleng tahun pelajaran 2014/2015 yang berjumlah 132 orang. Sampel penelitian ditentukan dengan teknik random sampling dan diperoleh siswa SD No. 2 Penglatan sebanyak 38 orang sebagai kelompok eksperimen dan siswa SD No. 2 Alasangker sebanyak 40 orang sebagai kelompok kontrol. Data kemampuan berpikir kritis siswa dikumpulkan dengan menggunakan tes uraian dan dianalisis menggunakan teknik analisis statistik deskriptif dan statistik inferensial (uji-t). Hasil penelitian ini menunjukkan bahwa: (1) kemampuan berpikir kritis siswa kelompok eksperimen berada pada kategori tinggi; (2) kemampuan berpikir kritis siswa kelompok kontrol berada pada katagori sedang; (3) terdapat berbedaan yang signifikan kemampuan berpikir kritis antara kelompok siswa yang dibelajarkan dengan model pembelajaran berbasis proyek dan kelompok siswa yang dibelajarkan dengan model pembelajaran konvensional. Dengan demikian dapat disimpulkan bahwa model pembelajaran berbasis proyek berpengaruh signifikan terhadap kemampuan berpikir kritis siswa pada mata pelajaran IPA dibandingkan dengan model pembelajaran konvensional.Kata Kunci : pembelajaran berbasis proyek, berpikir kritis
This study was aimed to (1) describe an ability of critical thinking of students from experimental group who were treated by project based learning model, (2) describe an ability of critical thinking of students from control group who were treated by conventional technique (3) to know a significant different of ability of critical thinking between students who were treated by project based learning model and students who were treated by conventional technique in natural science course in the fifth grade of elementary school in Gugus IV Buleleng district. This research was a quasi experimental research with using non-equivalent post test only of control group design. The population of this research was all students of fifth grade elementary school in Gugus IV Buleleng district in academic year 2014/2015 who involved 132 people. The sample of this research was determined through random sampling technique and chosen 38 people as experimental group and 40 students of SD No. 2 Alasangker as control group. The data of critical thinking ability of students was collected by using essay and analyzed through using descriptive analysis and inferential statistic (T-test). The result of this study showed that: (1) an ability of critical thinking of students from experimental group was in the high category; (2) an ability of critical thinking of students from control group was in the middle category; (3) there was a significant different of critical thinking between group of students who were treated by project based learning model and group of students who were treated by conventional technique. It can be concluded that the project-based learning model a significant effect on students' critical thinking skills in science subjects compared to conventional learning model.
