title: Students' perceptions of the educational environment in a Greek Dental School, as measured by DREEM.
abstract: OBJECTIVE
  The aim of this study was to estimate the dental students' perceptions of their educational environment and to identify any differences related both to their gender and semester of studies.
  
  
  METHODS
  The translated and validated in Greek Dundee Ready Education Environment Measure (DREEM) questionnaire was distributed to all 2nd- to 5th-year students of the Athens Dental School. The questionnaire consisted of 50 statements organised in five subscales (perceptions of learning, teachers, atmosphere, academic self-perceptions and social self-perceptions). Internal validity was checked with Cronbach alpha. Confirmatory factor analysis (CFA) was performed under the same conditions as the original inventory. Mean statement, subscale and overall scores were calculated and given as percentages.
  
  
  RESULTS
  The response rate was 64%. Overall Cronbach alpha was 0.93 (excellent). CFA produced five meaningful subscales, not matching the original ones. The overall DREEM mean score was 56%. Gender did not influence the findings. The students' perceptions of the educational environment with the exception of the academic self-perceptions were more positive in the pre-clinical years. Statistically significant differences were revealed only for the 'learning' subscale between the 3rd- and the 4th-year students. Seventy-eight percent of the statements were in the positive side. The lowest scores were related to students' stress, tiredness and lack of appropriate feedback from the teachers, and the highest were related to accommodation, school friends and perceptions that they feel socially comfortable in class.
  
  
  CONCLUSIONS
  Students' perceptions of the educational environment were reasonably positive, with no gender difference. However, some weaknesses were identified, particularly in the clinical years. Further research is needed to clarify appropriate interventions.
