Abstrak

Penelitian ini bertujuan untuk menganalisis pengaruh model pembelajaran Problem Based Learning (PBL) terhadap kemampuan berpikir kreatif siswa MTs. Penelitian menggunakan pendekatan kuantitatif dengan desain quasi-eksperimen. Populasi penelitian adalah seluruh siswa kelas VIII MTs Negeri 1 Purworejo sebanyak 240 siswa. Sampel dipilih dengan teknik cluster random sampling, sehingga terpilih kelas VIII D (30 siswa) sebagai eksperimen dan VIII A (31 siswa) sebagai kontrol. Instrumen penelitian berupa tes kemampuan berpikir kreatif dengan indikator fluency, flexibility, originality, dan elaboration. Validitas isi instrumen diperoleh melalui expert judgment, sedangkan reliabilitas diuji menggunakan Alpha Cronbach (0,82). Data dianalisis dengan uji-t dan perhitungan effect size Cohen’s d. Hasil penelitian menunjukkan rata-rata nilai eksperimen (70,43) lebih tinggi dibandingkan kontrol (58,25), dengan thitung = 2,43 > ttabel = 2,001 pada taraf signifikansi 5% serta effect size sebesar 0,65 (kategori sedang). Hal ini membuktikan bahwa penerapan PBL berpengaruh signifikan dalam meningkatkan kemampuan berpikir kreatif siswa, khususnya pada aspek keluwesan dan keaslian.
