Penelitian ini mengggunakan penelitian kuantitatif dengan desain one grup pre test posttest desaign penelitian ini menggunakan 1 kelas eksperimen (kelas IV) dan 1 kelas uji coba (kelas V). Teknik pengumpulan data menggunakan tes essayberupa pretest dan posttest, data analisis menggunakan uji -t teknik independent sample t-test dengan taraf signifikansi 5% menggunakan program SPSS 16 for windows. Hasil analisis data uji normalitas menunjukan nilai signifikansi 0,966 > 0,05 maka dapat disimpulkan bahwa nilai pretest dan posttest berdistribusi normal dan berdasarkan hasil uji t-tes t-hitung < t-tabel (-12.074 < 0,05) maka Ho di tolak artinya ada perbedaan antara pretest dan posttest artinya model pembelajaran problem based learning mempunyai pengaruh pada kemampuan berpikir kritis peserta didik pada materi gaya kelas IV SD Plus Cahaya Budaya.
