BackgroundIn 2007, the Faculty of Medical Sciences, University of Sri Jayewardenepura revised its medical curriculum from discipline-based to one that was student-centered and integrated. This study aimed to evaluate the perceptions of students regarding the educational environment and compare them to those prior to curricular revision.MethodsThe Dundee Ready Education Environment Measure (DREEM) questionnaire was administered to all volunteering students enrolled in the medical degree programme at the time of the study (n = 595). Results were compared to DREEM scores obtained prior to curricular revision.ResultsThe overall DREEM score and sub-scale scores were positive and showed improvement compared to previous scores. The score for Students’ Perceptions of Atmosphere showed progression from ‘there are many issues which need changing’ to the next highest category ‘a more positive attitude’. The mean scores in pre-clinical, para-clinical and clinical phases also showed an improvement. ‘The teachers are knowledgeable’ was the highest rated item overall and within each phase of learning. All sub-scales were rated highest by pre-clinical students and lowest by para-clinical students, in contrast to previous results where such patterns were not observed. Certain items, especially those related to teaching/learning, received exclusively low scores in particular student subsets.ConclusionsStudents’ perceptions towards the educational environment overall, have improved following curricular revision. However, certain negative areas warranting further evaluation were highlighted.
