Performance and Preference of Problem Based Learning (Pbl) and Lecture Based Learning Among Selected Medical Students of Nepal
Abstract Background: This study aims to compare student’s understanding and knowledge retention when taught through PBL (Problem Based Learning) and Lecture, and compare student’s perception about PBL and Lecture in medical education. Method: This is cross-sectional study done among medical students of PBL based medical school. Ethical approval was taken from IRC-PAHS. To assess understanding and knowledge retention, 50 vignettes based Multiple Choice Questions were administered, half of which were taught through PBL sessions and remaining half were taught in didactic Lectures during basic science years of medical school. To assess student's preference on PBL and Lecture, separate pre-validate perception questionnaire was used.Result: Out of 107 students, 99 participated in understanding and knowledge retention questionnaire and 107 filled perception questionnaires. Understanding and knowledge retention of students was found to be same for topics taught by PBL and Lecture with median score of 17 and 16 respectively. PBL was preferred more for physiology(59.81%), pathology(51.40%) and pharmacology(53.27 %) concepts, and Lecture was more preferred for anatomy(78.50%), biochemistry(45.79%), and microbiology(42.99%) topics. Many students wanted same concepts to be taught through both PBL and Lecture, especially for anatomy. Combined Lecture by group of faculties and community-based programs were preferred for Community Health Science (CHS) contents and hospital ward-based teaching was preferred for Introduction to Clinical Medicine (ICM) rather than PBL or Lectures.Conclusion: Understanding and knowledge retention is same for topics taught by either PBL or Lecture during basic science years of undergraduate medical education. Students prefer PBL for physiology, pathology and pharmacology related concepts, conventional didactic Lecture for physiology and microbiology, and combination of Lecture and PBL sessions for Anatomy.
