Hasil belajar sejarah siswa SMA masih rendah. Kemampuan berpikir kritis merupakan salah satu keterampilan yang penting dimiliki siswa dalam menghadapi tantangan zaman. Model  Problem Based Learning (PBL) dianggap sebagai salah satu model pembelajaran yang efektif dalam meningkatkan kemampuan berpikir kritis siswa. Menggunakan desain penelitian pre-eksperimental one group pre-test post-test design. Teknik pengambilan sampel judgement purposive sampling. Populasi adalah siswa dari kelas XI 1 SMAN 1 BALONGPANGGANG. Pengumpulan data menggunakan Teknik observasi, lembar angket respon siswa, dan pre-test post-test. Hasilnya terdapat pengaruh. Uji Normalitas Data pretest dan posttest memperoleh hasil sig sebesar nilai pretest sig 0.283> 0.05 dan nilai posttest sig 0.358 >0.05. Uji Paired Sampel T-test sebesar 0,00 <0,05 nilai t hitung 13.682. Hasil uji hipotesis diperoleh sig 0,000< 0.05 sehingga  ditolak dan  diterima. Hasil normalized gain siswa adalah 0.59. Kemampuan berpikir kritis siswa berada pada kategori sedang. Sedangkan dalam kategori tafsiran efektivitas N-GAIN Score penggunaan model PBL adalah Cukup Efektif.
