Résumé:
The current research aims at investigating the impact of problem-based learning on EFL students’ critical thinking skills. Hence, we hypothesized that problem-based learning could be effective to improve students’ critical thinking skills. To test the validity of the hypothesis, the quantitative descriptive method is adopted through the administration of two questionnaires for EFL teachers and first-year Master students at the Department of English, 8 Mai 1945 Guelma University. The obtained findings indicated the strong impact of problem-based learning on improving students’ critical thinking skills. Therefore, problem-based learning should be adopted and taken into account to improve students’ critical thinking skills.
