Abstract Background and Objective:
Problem-Based Learning (PBL), as a student-centered approach, provides opportunities to enhance critical thinking, group collaboration, and the practical application of knowledge in real-world situations. This study aimed to compare the effects of PBL and traditional lecture-based methods on learning outcomes and student satisfaction among dental students in the "Systemic" course. Methods: This descriptive cross-sectional study was conducted with 87 fifth-semester dental students at Islamic Azad University, Tehran, during the second semester of 1403–1404. Students were randomly assigned to either the PBL or lecture group. The PBL group attended four one-hour sessions, while the lecture group participated in three one-hour sessions. Learning outcomes were assessed using pre-tests, post-tests, and a cumulative test, and student satisfaction was measured through a validated and reliable questionnaire. Results: No significant differences were found between the lecture and PBL groups in pre-test (p = 0.545), immediate post-test (p = 0.363), or 15-day post-test scores (p = 0.420). Repeated measures analysis revealed a significant increase in scores over time. Student satisfaction was significantly higher in the PBL group (64.2 ± 5.11) compared to the lecture group (57.3 ±2.11). There were no significant differences between the groups in age (p = 0.702), GPA (p = 0.529), or gender distribution (p = 0.891). Conclusion: Although PBL did not have a significant impact on learning scores, it increased student satisfaction and active participation, suggesting that it is an effective method for enhancing motivation and collaborative learning in dental education.
