title: Medical students' achievement on the Bachelor of Medicine, Bachelor of Surgery/Chirurgery Final Part I and II licensing examination: a comparison of students in problem-based learning, community-based education and service, and conventional curricula in Ghana.
abstract: OBJECTIVE
  Problem-based learning is an established method of teaching and learning in medical education. However, its impact on students' achievement on examinations is varied and inconsistent. We compared the levels of achievement on the Bachelor of Medicine, Bachelor of Surgery/Chirurgery (MB ChB) Part I and II licensing examination of students in problem-based learning, community-based education and service (PBL/COBES), and conventional curricula.
  
  
  METHODS
  In 2014, we analyzed the MB ChB Final Part I and II licensing examination results of students in three classes (2004, 2005, and 2006) of the School of Medicine and Health Sciences, University for Development Studies, Tamale, Ghana. Ninety-three students in the 2004 and 2005 cohorts followed a conventional curriculum, and 82 students in the 2006 cohort followed a PBL/COBES curriculum. Using appropriate statistical tools, the analysis compared individual discipline scores and the proportions of students who received distinction/credit/pass grades among the classes.
  
  
  RESULTS
  The PBL students had significantly higher mean and median scores than the conventional students in Obstetrics and Gynecology, Internal Medicine, Community Health and Family Medicine, Surgery, and Psychiatry, but not in Child Health and Pediatrics. Also, a significantly (P=0.0010) higher percentage, 95.1% (n=78), of the PBL students passed all the disciplines, compared to 79.6% (n=74) of the conventional students.
  
  
  CONCLUSIONS
  The PBL students significantly performed better in all the disciplines except child health and pediatrics, where the conventional students scored higher. These findings demonstrate that the benefits of the PBL/COBES curriculum are tangible and should be fostered.
