PENERAPAN MODEL PEMBELAJARAN KOOPERATIF TIPE TEAM ASSISTED INDIVIDUALIZATION (TAI) DALAM UPAYA PENINGKATAN KEMAMPUAN BERPIKIR KREATIF MATEMATIS SISWA
Abstract
Penelitian ini bertujuan untuk mengetahui apakah kemampuan berpikir kreatif
matematis siswa yang menerapkan model pembelajaran kooperatif tipe Team
Assisted Individualization (TAI) lebih baik dari pada kemampuan berpikir kreatif
matematis siswa yang menerapkan pembelajaran konvesional. Penelitian ini
dilaksanakan di kelas VII SMPN 1 Lebakwangi pada semester 2 tahun pelajaran 2015/
2016. Teknik pemgambilan sampel yang digunakan adalah random sampling. Metode
penelitian yang digunakan adalah metode eksperimen. Hasil tes kemampuan berpikir
kreatif matematis siswa diperoleh nilai rata-rata tes awal kelas eksperimen 32,83 dan
nilai rata-rata tes awal kelas kontrol 32,17. Sedangkan nilai rata-rata tes akhir kelas
eksperimen 48,25 dan nilai rata-rata kelas kontrol 37,42. Teknik analisis data
menggunakan uji-t untuk menguji hipotesis statistik. Pada uji perbandingan dua ratarata diperoleh nilai thitung = 2,040, nilai ttabel = 1,669, karena 2,040 > 1,669 atau
-2,040 < -1,669 maka H1 diterima, artinya kemampuan berpikir kreatif matematis
siswa yang menerapkan model pembelajaran kooperatif tipe Team Assisted
Individualization (TAI) lebih baik dari pada kemampuan berpikir kreatif matematis
siswa yang menerapkan pembelajaran konvesional.
