Pengaruh Penggunaan Model Pembelajaran Kooperatif Tipe Group Investigation (Gi) Terhadap Motivasi Belajar Dan Pemahaman Konsep Biologi Siswa SMA Negeri 2 Banjar

Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan model pembelajaran kooperatif tipe group investigation (GI) dan model pembelajaran konvensional terhadap motivasi belajar dan pemahaman konsep Biologi siswa. Rancangan eksperimen penelitian adalah “Non-Randomized Post-Test Only Control Group Design”, dengan melibatkan dua kelas. Polpulasi penelitian adalah siswa kelas X SMA Negeri 2 Banjar tahun pelajaran 2013/2014. Sampel diambil dari delapan kelas dengan tehnik Simpel Random Sampling. Data dianalisis dengan menggunakan statistik deskriptif dan MANOVA (Multivariat of Analisis Variance) dengan bantuan SPSS 17.0 For Windows dengan taraf signifikansi 5%. Hasil penelitian menunjukkan bahwa (1) terdapat perbedaan yang signifikan motivasi belajar dan pemahaman konsep Biologi antara siswa yang belajar dengan model pembelajaran kooperatif tipe group investigasi dengan siswa yang belajar dengan model pembelajaran konvensional (2) terdapat perbedaan yang signifikan motivasi belajar siswa yang belajar dengan model pembelajaran kooperatif tipe group investigasi dan siswa yang belajar dengan model pembelajaran konvensional, (3) terdapat perbedaan yang signifikan pemahaman konsep Biologi siswa yang belajar dengan model pembelajaran kooperatif tipe group investigasi dan siswa yang belajar dengan model pembelajaran konvensional.
