Abstract

Penelitian ini menggunakan bentuk kuasi eksperimen yaitu Nonequaivalent Control Group Design. Kelas eksperimen diberikan perlakuan berupa penggunaan model Pembelajaran Kooperatif Numbered Head Together (NHT) untuk kelas XI MIA 1, sedangkan untuk kelas konvensional diberikan perlakuan berupa model pembelajaran Eskpositori yaitu untuk kelas XI MIA 3. Analisis data dilakukan dengan menggunakan uji t, dimana hasil penelitian menunjukan: (1) ada peningkatan model pembelajaran Kooperatif Numbered Head Together (NHT) terhadap kemampuan matematis siswa. Hal ini diperoleh dari hasil pengujian statistik dengan uji t yaitu t hitung > t tabel=3,48 > 1,67 , maka H0 ditolak dan H1 diterima. (2) Berdasarkan perhitungan yang telah dilakukan menggunakan uji t’ maka didapat niai t hitung < t tabel=1,04 < 1,67, maka H0 diterima dan H1 ditolak. Oleh karena tidak terdapat perbedaan peningkatan kemampuan matematis siswa yang mendapatkan model pembelajaran Kooperatif Numbered Head Together dengan siswa yang mendapatkan model pembelajara Ekspositori siswa kelas XI MIA SMA Angkasa 1 Perdanakusuma. Kata Kunci : Kemampuan Matematis, Numbered Head Together (NHT), Ekspositori./ This study uses a quasi-experimental form, namely the Nonequaivalent Control Group Design. The experimental class was given treatment in the form of the Cooperative Learning Model Numbered Head Together (NHT) for class XI MIA 1, while the conventional class was given treatment in the form of an Expository learning model for class XI MIA 3. Data analysis was carried out using the t test, where the results showed : (1) there is an increase in the Numbered Head Together (NHT) Cooperative learning model on students' mathematical abilities. This is obtained from the results of statistical testing with the t test, namely t count > t tabel = 3.48 > 1.67 , then H0 is rejected and H1 is accepted. (2) Based on the calculations that have been carried out using the t' test, the value of t count < t table=1.04 < 1.67, then H0 is accepted and H1 is rejected. Because there is no difference in the increase in mathematical ability of students who get the Numbered Head Together Cooperative learning model with students who get the Expository learning model of class XI MIA students of SMA Angkasa 1 Perdanakusuma. Keywords: Mathematical Ability, Numbered Head Together (NHT), Expository.
