Abstract

Penelitian ini bertujuan untuk mengetahui apakah hasil belajar kimia siswayang mendapat model pembelajaran PBL yang diintegrasikan dengan kooperatiftipe NHT lebih tinggi daripada yang mendapat model pembelajaran PBL,mengetahui apakah kemampuan berpikir kritis siswa yang mendapat modelpembelajaran PBL yang diintegrasikan dengan kooperatif tipe NHT lebih tinggidaripada yang mendapat model pembelajaran PBL, mengetahui persenpeningkatan hasil belajar kimia siswa yang mendapat model pembelajaran PBLyang diintegrasikan dengan kooperatif tipe NHT dan mengetahui persenpeningkatan hasil belajar kimia siswa yang mendapat model pembelajaran PBLpada pokok bahasan kelarutan dan hasil kali kelarutan. Populasi dalam penelitianini adalah seluruh kelas XI MIA SMAN 16 Medan, yang berjumlah 4 kelassedangkan sampel dalam penelitian ini sebanyak 2 kelas yang diambil secarapurposif, yaitu kelas eksperimen I mengunakan model PBL yang diintegrasikandengan kooperatif tipe NHT dan kelas eksperimen II menggunakan model PBL.Berdasarkan analisa data diperoleh hasil pretest dan posttest kedua kelas yangberdistribusi normal dan kelompok yang homogen. Hasil posttest diperoleh rataratakelas eksperimen I 90,56, dan kelas eksperimen II 82,22. Rata-ratakemampuan berpikir kritis siswa pada kelas eksperimen I sebesar 2855.7 ,eksperimen II sebesar 2566,8. Hasil uji t untuk hipotesis hasil belajar diperolehthitung = 10 dan ttabel = 0,77 sehingga thitung > ttabel (10 > 0,77) maka Ha diterima,artinya hasil belajar kimia siswa yang mendapat model pembelajaran PBL yangdiintegrasikan dengan kooperatif tipe NHT lebih tinggi. Hasil uji t untuk hipotesiskemampuan berpikir kritis siswa diperoleh thitung = 3,38 dan ttabel = 0,77 sehinggathitung > ttabel (3,38 > 0,77) maka Ha diterima, artinya kemampuan berpikir kritissiswa yang mendapat model pembelajaran PBL yang diintegrasikan dengankooperatif tipe NHT lebih tinggi pada pokok bahasan kelarutan dan hasil kalikelarutan.
