Educational institutions worldwide are increasingly adopting innovative teaching methodologies to improve student engagement, critical thinking, and long-term knowledge retention. Problem-Based Learning (PBL) has emerged as a student-centered instructional approach that contrasts with traditional lecture-based teaching methods. While both approaches have strengths and limitations, evidence comparing their effectiveness remains a subject of ongoing academic discussion.

Objective

This study compares Problem-Based Learning and Traditional Teaching Methods in terms of academic performance, critical thinking skills, student satisfaction, collaborative learning, and knowledge retention among undergraduate students.

Methods

A comparative cross-sectional study was conducted among 500 undergraduate students from health sciences, engineering, and social sciences programs. Students were divided into two groups based on instructional exposure: Problem-Based Learning (n=250) and Traditional Teaching Methods (n=250). Academic performance, critical thinking scores, student satisfaction surveys, and knowledge retention assessments were analyzed using descriptive and inferential statistical techniques.

Results

Students exposed to PBL demonstrated significantly higher critical thinking scores (82.4 ± 8.7) compared to traditional learners (71.3 ± 9.5; p < 0.001). Student satisfaction was also higher in the PBL group (88.2%) than in the traditional group (67.5%). Knowledge retention after six months showed superior performance among PBL participants. Traditional teaching demonstrated advantages in content coverage and examination preparedness.

Conclusion

Problem-Based Learning promotes critical thinking, collaboration, and long-term knowledge retention, whereas traditional teaching remains effective for structured content delivery. A blended educational model integrating both approaches may provide optimal learning outcomes.
