Résumé
Introduction: Often there is a ‘hidden’ curriculum running alongside the planned curriculum as published in official statements of a medical school. The two aspects of the curriculum may not be in concordance, especially in a phase of change. In this study Dundee Ready Education Environment Measure (DREEM) was used as the tool to determine the level of concordance between two curricula. Method: The DREEM questionnaires were administered face-to-face to two batches of undergraduate medical students of Faculty of Medicine, University of Kelaniya, Sri Lanka. One batch was the first group to follow the integrated curriculum and the other was the last group to follow the discipline-based curriculum. Results: The total scores of both batches indicated a reasonably positive overall perception of the education environment, but still with considerable room for improvement. The scores of third year male students for the domains of student perception of learning and teaching were significantly lower than their female colleagues and the seniors, thus indicating where interventions should be prioritised. By analysing the responses to individual items, a collection of items which were perceived negatively by both batches of students were identified. The items represented all domains with variable degree. Discussion: In addition to its multiple utilities, a careful and deep interpretation of the DREEM results can be used to identify a group affected specifically by the educational environment, possibly caused by a lack of concordance between the planned and the hidden curricula of the same institution.
