Abstract

Penelitian ini bertujuan untuk mendeskripsikan kemampuan berpikir kreatif matematis siswa salah satu SMP di Kota Lahat. Pada penelitian ini menggunakan jenis penelitian deskriptif-kualitatif. Sampel dalam penelitian ini diambil 88 siswa kelas VIII. Pengumpulan data yang digunakan adalah instumen tes tertulis dan wawancara. Setelah dilakukan tes tertulis, dipilih subjek untuk diwawancara. Pemilihan subjek wawancara berdasarkan hasil tes tertulis kemampuan berpikir kreatif matematis dan Tingkat Kemampuan Berpikir Kreatif (TKBK) siswa. Analisis data yang dilakukan yaitu (1) Reduksi data, (2) Penyajian data dan (3) Penarikan simpulan (verifikasi). Hasil penelitian menunjukkan sebagai berikut: (1) Kemampuan berpikir kreatif matematis siswa salah satu SMP di Kota Lahat masih sangat rendah dengan rata-rata persentase 20%. Dari 88 siswa yang menjadi sampel, 30 siswa berada di TKBK level 0 (Tidak Kreatif), 35 siswa berada di level 1 (Kurang Kreatif), 19 siswa berada di level 2 (Cukup Kreatif) dan 4 siswa berada di level 3 (Kreatif) serta tidak ada siswa yang berada di level 4 (Sangat Kreatif). (2) Rata-rata persentase tertinggi ada pada indikator fleksibelitas yaitu 39%, indikator kefasihan 33% dan indikator terendah ada di indikator kebaruan yaitu rata-rata persentasenya 15%. (3) Rendahnya kemampuan berpikir kreatif matematis pada siswa disebabkan siswa kurang latihan mengerjakan soal-soal yang memiliki indikator kemampuan berpikir kreatif matematis sehingga masih kurang dalam memahami maksud soal.
