Penelitian ini adalah penelitian eksperimen dengan desain penelitian pretest-posttest control group design yang bertujuan untuk mengetahui kemampuan berpikir kritis matematis siswa dengan menerapkan model kooperatif tipe the power of two. Satuan eksperimen penelitian ini adalah seluruh siswa kelas VIII SMP Negeri 1 Palopo. Teknik pengambilan sampel pada penelitian ini adalah Purposive Sampling dan terpilih satu kelas eksperimen yaitu kelas VIII.F dan kelas VIII.E sebagai kelas kontrol. Kelas eksperimen diajar menggunakan model pembelajaran kooperatif tipe the power of two dan kelas kontrol diajar menggunakan model pembelajaran konvensional yaitu model pembelajaran discovery learnin. Hasil penelitian ini adalah (1) kemampuan berpikir kritis matematis siswa kelas VIII SMP Negari 1 Palopo sebelum diterapkan model pembelajaran kooperatif tipe the power of two dan model pembelajaran konvensional berada pada kategori sangat rendah; (2) kemampuan berpikir kritis matematis siswa kelas VIII SMP Negari 1 Palopo setelah diterapkan model pembelajaran kooperatif tipe the power of two berada pada kategori rendah dan model pembelajaran konvensional berada pada kategori sedang; (3) peningkatan kemampuan berpikir kritis matematis siswa yang diajar dengan model pembelajaran kooperatif tipe the power of two lebih baik daripada siswa yang diajar dengan pembelajaran konvensional; (4) tidak terdapat perbedaan kemampuan berpikir kritis matematis siswa kelas yang diajar dengan model pembelajaran kooperatif tipe the power of two dan siswa yang diajar dengan pembelajaran konvensional.
