This research aimed to analyze the improvement of mathematics criticalthingking skill and student's self conceptwith using group investigation (GI) learning andconventional learningmodel. This research was quasi experiment and the design of this research was pre-test-post-test control group design. The data were collected from students in 7th grade of SMP Negeri 5 Ambon. By using purposive sampling, two classes were involved as samples where one class was as an experiment class and anotherwas as control class.The instrument used to collect the data were the mathematics critical thingkingskill test and questioner of self concept. The data of mathematics criticalthingking skill were analyzed by using t-test, ANOVA two ways, and ANOVA one ways, where student's concept were analyzed by using t- test. The results showed that, (1) the improvement of mathematics criticalthingking skill using group investigation learning were better than conventional learning; (2) the improvement of mathematics criticalthingking skill using GI learning were better than conventional learning in terms of categoryability ofearlymathematics students (top, middle, bottom); (3) There are differences gain in improvementof mathematical critical thinking skills students GI learning and conventional learning in terms of categoryability ofearlymathematics students (top, middle, bottom; and (4) students' mathematics self-concept of students onGI learning were beter than conventional learning. Keywords: group investigation (GI)learning, mathematicscritical thinking skills, and mathematics self concept. Penelitian ini bertujuan untuk menganalisis peningkatan kemampuan berpikir kritis dan self concept matematis siswa dengan menggunakan model pembelajaran group investigation (GI) dan konvensional. Penelitian ini adalah penelitian eksperimen kuasi dengan desain pre-test-post-test control group design. populasi dalam penelitian ini adalah siswa kelas VII SMP Negeri 5 Ambon. Melalui teknik purposive sampling, dua kelas dipilih sebagai sampel yaitu satu kelas sebagai kelas eksperimen dan yang lainnya adalah kelas kontrol. Instrumen yang digunakan berupa soal tes kemamuan berpikir kritis dan lembar angket skala self concept. Analis data kemampuanberpikir kritismatematismenggunakanuji-t dan ANOVA DuaJalur dan ANOVA Dua Jalur, sedangkanself conceptmenggunakanuji-t. Hasil penelitian menunjukan bahwa, (1) peningkatan kemampuan berpikir kritis matematis siswa yang mendapat pembelajaran GI lebih baik dari pembelajaran konvensional; (2) peningkatan kemampuan berpikir kritis matematis siswa yang mendapat pembelajaran GI lebih baik dari pembelajaran konvensional, ditinjau dari kategori kemampuan awal (tinggi, sedang, dan rendah); (3) terdapat perbedaan gain dalam peningkatan kemampuan berpikir kritis matematis siswa yang mendapat pembelajaran GI dan konvensional ditinjau dari kemampuan awal (tinggi, sedang, dan rendah); dan (4) self concept matematis siswa yang mendapat pembelajaran GI lebih baik daripada siswa yang mendapat pembelajaran seccara konvensional. Kata kunci: Pembelajaran group investigation (GI), kemampuan berpikir kritis matematis, dan self concept matematis.
