Rendahnya kemampuan berpikir kritis siswa dalam pembelajaran Geografi masih menjadi permasalahan di sekolah. Salah satu model pembelajaran yang dapat digunakan untuk mengatasi permasalahan tersebut adalah Problem-Based Learning yang menekankan pada keterlibatan aktif siswa dalam memecahkan masalah nyata. Penelitian ini bertujuan untuk menganalisis pengaruh penerapan model pembelajaran Problem-Based Learning berbantuan film dokumenter terhadap kemampuan berpikir kritis siswa kelas XI di MAN 1 Aceh Besar. Penelitian ini menggunakan pendekatan kuantitatif dengan metode kuasi eksperimen menggunakan desain non-equivalent control group. Populasi penelitian adalah seluruh siswa kelas XI MAN 1 Aceh Besar dengan mengambil sampel dua kelas (kelas eksperimen dan kelas kontrol) melalui teknik purposive sampling dari enam kelas paralel yang tersedia. Pengumpulan data dilakukan dengan menggunakan tes kemampuan berpikir kritis berupa pre-test dan post-test. Data dianalisis melalui uji prasyarat yang meliputi uji normalitas dan uji homogenitas, kemudian dilanjutkan dengan uji hipotesis menggunakan uji-t untuk mengetahui pengaruh perlakuan terhadap variabel yang di teliti. Hasil analisis menunjukkan bahwa nilai thitung "2,3375" > ttabel 1,6759 pada taraf signifikansi 5%. Dengan demikian, terdapat pengaruh yang signifikan dari penerapan model pembelajaran Problem-Based Learning berbantuan film dokumenter terhadap kemampuan berpikir kritis siswa dalam pembelajaran Geografi kelas XI di MAN 1 Aceh Besar.

Kata Kunci: Problem-Based Learning, film dokumenter, berpikir kritis.

Fajriyani. (2026). The Effect of Problem-Based Learning Model Assisted by Documentary Films on Students’ Critical Thinking Skills in Geography Learning for Grade XI at MAN 1 Aceh Besar. [Undergraduate Thesis. Universitas Syiah Kuala]. Supervised by Dr. Mirza Desfandi, S.Pd., M.Soc.Sc., and Ruliani, S.Pd., M.Pd. The low level of students’ critical thinking skills in Geography learning remains a problem in schools. One instructional model that can be used to address this issue is Problem-Based Learning, which emphasizes students’ active involvement in solving real-world problems. This study aims to analyze the effect of implementing the Problem-Based Learning model assisted by documentary films on the critical thinking skills of eleventh-grade students at MAN 1 Aceh Besar. This research employed a quantitative approach using a quasi-experimental method with a non-equivalent control group design. The population consisted of all eleventh-grade students of MAN 1 Aceh Besar. The sample included two classes (an experimental class and a control class) selected through purposive sampling from six available parallel classes. Data were collected using a critical thinking skills test administered as a pre-test and post-test. The data were analyzed through prerequisite tests, including normality and homogeneity tests, followed by hypothesis testing using an independent samples t-test to determine the effect of the treatment on the studied variable. The results of the analysis showed that the calculated t-value (2.3375) was greater than the t-table value (1.6759) at the 5% significance level. Therefore, it can be concluded that there is a significant effect of implementing the Problem-Based Learning model assisted by documentary films on students’ critical thinking skills in eleventh-grade Geography learning at MAN 1 Aceh Besar. Keywords: Problem-Based Learning, documentary films, critical thinking skills.
