Abstract
This study aimed to determine the differences in the chemistry learning outcomes using cooperative learning model type Numbered Head Together with Think-Pair-Share on the material of atomic structure and periodic table in class XI SMAN 9 Palu. This type of research was a quasi-experimental research with the nonrandomized pretest-posttest design. The population in this research was 44 students of class XI IPA in SMA Negeri 9 Palu who registered in the academic year 2017/2018. The sampling technique used was saturated sampling. The sample in this study were 22 students of class XI IPA 1 as experimental class 1 and 22 students of class XI IPA 2 as experimental class 2. The data of the research were analyzed using a one-party t-test statistic with the prerequisite test, normality test, and homogeneity. The result of data analysis obtained, X̅1 value of chemistry learning on the students of experimental class 1 was 79.86 (SD = 7.15) whereas in the experimental class 2 students X̅2 value was 73.95 (SD = 8.26). The result of hypothesis testing was obtained t > t1 – α was 2,55 > 1.68 with a significant level (α = 0.05) and degrees of freedom = 42. This showed that Ho was rejected and Ha was accepted so that it can be concluded that there were differences in the results of chemistry learning outcomes using cooperative learning model type Numbered Head Together with Think-Pair-Share on the material of the atomic structure and the periodic table.
Highlights
Pendahuluan1 Pelajaran kimia merupakan mata pelajaran yang cenderung sulit diterima dan dipahami oleh siswa, kerena membutuhkan pemahaman konsep yang cukup tinggi

Summary
Kedua tipe pembelajaran kooperatif tersebut mempunyai persamaan yaitu guru mengajukan permasalahan atau pertanyaan kemudian siswa diminta untuk bekerjasama dan mendiskusikan jawaban atas permasalahan atau pertanyaan tersebut (Murti dkk., 2014). Tulisan ini dimaksudkan untuk mendeskripsikan tentang perbedaan hasil belajar kimia menggunakan model pembelajaran kooperatif tipe Numbered Heads Together dengan tipe think pair share pada materi struktur atom dan sistem periodik di kelas XI SMAN 9 Palu. Tes hasil belajar siswa disusun dengan maksud untuk memperoleh data hasil belajar siswa setelah belajar-mengajar sehingga diketahui ada tidaknya perbedaan hasil belajar kimia siswa menggunakan model pembelajaran kooperatif tipe NHT dengan tipe TPS terhadap hasil belajar kimia di kelas XI SMAN 9 Palu pada pokok bahasan struktur atom dan sistem periodik. Hasil dan Pembahasan Hasil penelitian ini mencakup hasil selama proses kegiatan belajar mengajar di kelas XI IPA 1 menggunakan model pembelajaran kooperatif tipe Numbered Head Together (NHT) dan XI IPA 2 menggunakan model pembelajaran kooperatife tipe Think-Phair-Share (TPS) di SMA Negeri 9 Palu, yang meliputi hasil belajar kimia siswa. Rentang dan frekuensi skor tes akhir hasil belajar kimia pada siswa kelas eksperimen
