Abstract

This research has been conducted to recognize the improvement of the students study achievement in polymer lesson at 12th grade of science program in SMAN 2 Pontianak by the application of cooperative learning model type numbered heads together. The form of this research is Classroom Action Research. The research was conducted in three cycles. The students learn about the meaning and the reaction how the polymer is formed, the classification of polymer, kinds of plastic, the use and the impact of polymer as well. The instruments used are the students’ test achievement and questioners. Result of this research on the first cycle the percentage of the study completeness is 70,97%, the second cycle is 75% and the third cycle is 84,38%. It can be concluded that there is improvement on the students study result. It is recommended for the teachers to choose cooperative learning model type numbered heads together become one of the learning model alternative in polymer lesson to improve of the students’ study result. Keywords: Numbered heads together, polymer.

Abstract

This research has been conducted to figure out the improvement of the students learning activities in polymer lesson at twelft grade of science program in SMAN 2 Pontianak by the application of cooperative learning model type numbered heads together. The form of this research is Classroom Action Research. The research was conducted in three cycles. The students learn about the meaning and the reaction how the polymer is formed, the classification of polymer, kinds of plastic, the use and the impact of polymer as well. The instrument used is observation of the students’ activities and questioners. Based on the data analysis, it can be concluded that there is improvement on the students learning activities. The percentage of the students activities is 29,03% in the first cycle, 43,75% in the second cycle and 84,38% in the third cycle. It is recommended for the teachers to choose cooperative learning model type numbered heads together to become one of the learning model alternative in polymer lesson to improve  the students’ learning activities. Keywords : Cooperative learning, numbered heads together.

Abstract

Penelitian ini dilakukan untuk mengetahui peningkatan hasil belajar siswa pada materi kesetimbangan kimia kelas XI MIPA SMA Negeri 2 Pontianak melalui penerapan model pembelajaran kooperatif tipe STAD berbantuan modul. Metode penelitian ini adalah penelitian tindakan kelas (classroom action research). Pengumpulan data melalui observasi, tes, dan kuesioner. Hasil penelitian menunjukkan bahwa ketuntasan pada siklus I sebesar 27,27%, meningkat menjadi 51,43% pada siklus II, dan meningkat menjadi 77,78% pada siklus III. Predikat super team sebesar 62,50% pada siklus I, meningkat menjadi 87,50% pada siklus II, dan meningkat menjadi 100% pada siklus III. Dapat disimpulkan bahwa terjadi peningkatan hasil belajar siswa setelah penerapan model pembelajaran kooperatif tipe STAD berbantuan modul. Model kooperatif tipe STAD dapat menjadi alternatif untuk meningkatkan hasil belajar siswa.
