Penelitian ini merupakan penelitian tindakan kelas yang terdiri dari tiga tahap, yaitu (1) perencanaan, (2) tindakan dan observasi, dan (3) refleksi. Penelitian dilakukan dalam tiga siklus. Teknik pengumpulan data yang digunakan adalah observasi, wawancara, dan tes. Pelaksanaan penerapan model project-based learning dari siklus I, siklus II, dan siklus III berturut-turut yaitu 85,75%; 89,65%; dan 93,30% pada aktivitas dosen, sedangkan pada aktivitas mahasiswa, dari siklus I, siklus II, dan siklus III berturut-turut yaitu 87,85%; 89,63%; dan 94,12%. Melalui penerapan model project-based learning yang telah dilaksanakan, terjadi peningkatan nilai rata-rata keterampilan berpikir kritis mahasiswa dari siklus I, siklus II, dan siklus III berturut-turut yaitu 76,13; 82,75; dan 86,50; sehingga dapat disimpulkan bahwa penerapan model project-based learning dapat meningkatkan keterampilan berpikir kritis mahasiswa.
