Penelitian ini bertujuan untuk mengetahui: 1) deskripsi keterampilan berpikir kritis dalam pembelajaran IPA siswa yang dibelajarkan dengan pembelajaran konvensional, 2) deskripsi keterampilan berpikir kritis dalam pembelajaran IPA siswa yang dibelajarkan dengan model pembelajaran kooperatif tipe GI (Group Investigation), 3) pengaruh yang signifikan pada keterampilan berpikir kritis dalam pembelajaran IPA antara kelompok siswa yang dibelajarkan dengan model pembelajaran kooperatif tipe GI (Group Investigation) dengan kelompok siswa yang dibelajarkan dengan pembelajaran konvensional pada siswa kelas V Tahun Pelajaran 2013/2014 di SD di gugus VII Kecamatan Tejakula. Jenis penelitian ini adalah penelitian quasi eksperimen dan menggunakan desain post-test only control group design. Subjek penelitian ini adalah seluruh siswa kelas V di SD Gugus VII Kecamatan Tejakula Tahun Pelajaran 2013/2014 yang berjumlah 88 orang. Tehnik pengambilan sampel adalah tehnik random sampling, tetapi yang dirandom adalah kelas. Data dikumpulkan dengan instrumen tes berpikir kritis berbentuk uraian. Data yang dikumpulkan dianalisis menggunakan analisis statistik deskriptif dan statistik inferensial (uji-t). Hasil penelitian ini menemukan bahwa: 1) skor keterampilan berpikir kritis dalam pembelajaran IPA pada siswa yang mengikuti pembelajaran dengan pembelajaran konvensional cenderung sedang, dengan mean 32,05, 2) skor keterampilan berpikir kritis dalam pembelajaran IPA pada siswa yang mengikuti pembelajaran dengan model pembelajaran kooperatif tipe GI (Group Investigation) cenderung tinggi, dengan mean 41,7, 3) terdapat pengaruh yang signifikan pada keterampilan berpikir kritis antara kelompok siswa yang dibelajarkan dengan model pembelajaran kooperatif tipe GI (Group Investigation) dengan kelompok siswa yang dibelajarkan dengan pembelajaran konvensional, dengan thit > ttab (thit = 28,82 > ttab = 45).Kata Kunci : GI (Group Investigation), berpikir kritis
This study aims to determine: 1) description of critical thinking skills in science teaching students who learned with conventional learning, 2) description of critical thinking skills in science teaching students who learned with GI (Group Investigation), 3) significant influence in the skill critical thinking in science learning among groups of students who learned with GI (Group Investigation) with a group of students who learned with conventional learning the fifth grade students in the academic year 2013/2014 in primary schools in the cluster VII of Tejakula district. This research is a quasi-experimental research design and using post-test only control group design . The subjects were all fifth grade students in elementary group Tejakula District VII Academic Year 2013/2014 which amounts to 88 people. Sampling technique is random sampling technique, but is randomized class. Data were collected with a critical thinking test instruments in the form of multiple description. The data collected were analyzed using descriptive statistics and inferential statistics (t-test). Results of this study found that: 1) critical thinking skills scores in science teaching on students who take lessons with conventional learning tend to be low, with a mean of 32,05, 2) score of critical thinking skills in science teaching on students who take learning to the GI (Group Investigation) tend to be high, with a mean of 41,7, 3) there are significant influence in critical thinking skills among the group of students who learned with the GI (Group Investigation) with a group of students who learned with conventional learning, with tarithematic > ttable (tarithematict = 28,82> ttable = 45).
