Kemampuan berpikir kritis dan kemampuan pemecahan masalah merupakan kompetensi yang harus dimiliki oleh siswa untuk dapat bersaing di era globalisasi. Penelitian ini bertujuan untuk mengetahui peningkatan kemampuan berpikir kritis dan kemampuan pemecahan masalah siswa pada materi sistem reproduksi manusia. Metode penelitian yang digunakan adalah weak experiment, dengan desain penelitian the one group pretest posttest design. Partisipan yang telibat sebanyak 32 siswa kelas XI di salah satu SMA Negeri di Kota Bandung. Data kemampuan berpikir kritis dijaring melalui tes uraian dengan indikator soal berdasarkan framework Inch, sedangkan data kemampuan pemecahan masalah dijaring melalui soal uraian dengan indikator soal berdasarkan framework Kirkley. Teknik pengumpulan data dilakukan melalui tes dan non tes berupa angket untuk mengetahui respons siswa terhadap implementasi PBL terintegrasi blended learning. Peningkatan kemampuan berpikir kritis dan kemampuan pemecahan masalah siswa dilihat berdasarkan data hasil pretest dan posttest yang dianalisis dengan N-gain. Berdasarkan perhitungan N-gain didapatkan bahwa peningkatan kemampuan berpikir kritis yaitu 0,73 (kategori tinggi) dan kemampuan pemecahan masalah yaitu 0,70 (kategori tinggi). Hasil ini menunjukkan bahwa PBL terintegrasi blended learning dapat meningkatkan kemampuan berpikir kritis dan kemampuan pemecahan masalah siswa pada materi sistem reproduksi manusia.
