Abstract

Penelitian ini bertujuan untuk memperlihatkan pengaruh hasil belajar kimiasiswa, peningkatan hasil belajar kimiasiswayang diajarkan dengan model pembelajaran Problem Based Learning dengan model Pembelajaran Langsung (Direct Intruction), dan hubungan antara aktivitas dengan hasil belajar kimia siswa yang diajarkan dengan model pembelajaran Problem Based Learning pada materi ikatan kimia kelas X MAN 1 Medan. Sampel diambil secara purposive sampling sehingga diperoleh dua kelas yaitu kelas yang diberi pengajaran dengan menggunakan model pembelajaran Problem Based Learning sebagai kelas eksperimen dan kelas yang diberi pengajaran model pembelajaran Langsung (Direct Instruction) sebagai kelas kontrol.Penelitian ini menggunakan instrument test yang telah diujicobakan dan telah valid. Data hasil belajar siswa diuji normalitas dan homogenitasnya, hasil yang didapat kedua kelompok sampel homogen dan berdistribusi normal. Hasil pengolahan data menunjukkan siswa pada kelas eksperimen memiliki rata-rata nilai pretest 42,000 dan postest 84,375. Sedangkan siswa pada kelas kontrolmemiliki rata-rata nilai pretest 39,375 dan postest 74,125. Peningkatan hasil belajar siswa dihitung dengan bentuk gain ternormalisasi dan didapatkan persen peningkatan belajar siswa pada kelas eksperimen sebesar 73,13%, sedangkan persen peningkatan belajar siswa kelas kontrol sebesar 56,93%. Uji hipotesis dilakukan dengan menggunakan uji t satu pihak dan diperoleh thitung = 8,346 sedangkan ttabel = 1,652 untuk α = 0.05 dan db = 78. Dengan demikian thitung> ttabel, maka Ha diterima yakni Hasil belajar kimiasiswa yang diajardengan model pembelajaran Problem based learning lebih tinggi dari hasil belajar kimia siswa dengan model Pembelajaran Langsung (Direct Intruction),danterdapatpeingkatanhasilbelajar yang signifikanyaknisebesar 16,20 % pada pokok bahasan ikatan kimia di kelas X MAN 1 Medan
