Aims: To examine the reliability and validity of the Dundee Ready Educational Environment Measure (DREEM) amongst New Zealand students in the first professional year of the Bachelor of Dental Surgery (BDS) and Bachelor of Oral Health (BOH) programmes. Method: In 2009 and 2010, students’ perceptions of the educational environment were evaluated using a modified version of the 50‐item DREEM, completed on the first and last day of their first professional year. Individual DREEM items’ strengths and weaknesses were identified. The difference or dissonance between students’ expectations and actual experience was determined by subtracting the Actual DREEM score (for each item or subscale) from the Expected DREEM score. Effect‐size statistics were calculated, and internal consistency was tested using Cronbach’s alpha. Results: Overall, 82% of 2009 and 2010 BDS and BOH students in their first professional year completed the Expected and Actual DREEM (N = 176). Both groups identified the ‘overemphasis of factual learning’ as an Expected and Actual aspect and ‘memorising all I need to know’ as an Actual aspect of the educational environment. Internal consistency was high for the overall DREEM and the BDS and BOH Expected DREEM (0.89 and 0.88, respectively) and excellent for both the BDS and BOH Actual DREEM (0.92 and 0.90, respectively). Conclusion: Overall, students entering the courses anticipated a number of strengths and weaknesses and those expectations were relatively similar in the different programmes (BDS and BOH). The DREEM showed excellent internal consistency for the overall scores, and that for the subscale scores was generally acceptable. The study confirms the DREEM’s utility for the NZ dental education environment. 相似文献

Objectives: The educational climate in which future doctors are trained is an important aspect of medical education. In contrast to human medicine, it has been rather neglected in dental educational research. The aim of the study was to supplement this lack by applying and validating the Dundee Ready Education Environment Measure (DREEM) for the first time in a German‐speaking sample of dental students. Methods: All dental students at the Medical Faculty of Heinrich‐Heine‐University Düsseldorf were asked to complete a German adaptation of the DREEM and the Düsseldorf Mission Statement Questionnaire (DMSQ) in a paper‐pencil survey. Data from 205 participants were analysed. Psychometric validation included analysis of item homogeneity and discrimination, test reliability, criterion and construct validity (convergent, factorial). Results: DREEM item parameters were satisfactory, reliability (α = 0.87) and convergent validity (r = 0.66 with DMSQ) were also high. Factor analyses, however, yielded dimensions which did not fully correspond to the original DREEM subscales. Overall perception of the educational environment was positive (DREEM total score = 122.95 ± 15.52). Students in the clinical part of course rated the atmosphere more negatively, but their academic self‐perception more positively than preclinical students. Conclusions: Showing satisfactory psychometric properties, DREEM proved suitable for assessing educational environments among dental students. Given the right circumstances, e.g., small and early clinically oriented classes, traditional curricula can generate positive environments. 相似文献

The significance of the educational environment in health professions academic institutions, increasingly recognized on a global scale, is fundamental to effective student learning. This study was carried out to evaluate students' perceptions of the educational environment in five undergraduate dental institutions in Pakistan. This non-interventional study used a postal questionnaire based on the Dundee Ready Educational Environment Measure (DREEM). The subjects were dental students taking the final professional B.D.S. examination at five dental institutions affiliated with the University of Health Sciences, Lahore, Pakistan. A total of 197 students participated in the study (response rate of 83.82 percent). The overall DREEM score was 115.06 (Cronbach's alpha 0.87). Nine items recorded scores <2 and were flagged for remediation. Significant differences were observed between students' perceptions of learning and of teachers (p<0.05). Many issues challenge the quality and delivery of dental education in Pakistan, and dental institutions need to develop robust mechanisms to incorporate contemporary international trends in dental education in order to improve the educational environment. 相似文献

Aim: 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. Materials and 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. 相似文献

Aim: To develop and validate an instrument, the Hong Kong Rapid Estimate of Adult Literacy in Dentistry (HKREALD‐30). Methods: The Rapid Estimate of Adult Literacy in Dentistry (REALD‐99) was translated into Chinese and modified in the pretest. A total of 200 parents of pediatric dental patients were interviewed using this modified scale and administered additional three sets of self‐reported questionnaires. The 99 items of the scale were reduced to 30 (HKREALD‐30). Concurrent validity was tested by comparing the HKREALD‐30 scores with the participants’ educational level, pattern of dental visits and reading habits. Convergent validity was tested by examining the association between HKREALD‐30 and the Test of Functional Health Literacy in Dentistry (TOFHLiD). The test–retest reliability and internal consistency of HKREALD‐30 were also evaluated. Results: A significant correlation (P < 0.01) was found between HKREALD‐30 and participants’ reading habits. HKREALD‐30 was also highly correlated with TOFHLiD (Spearman’s rho = 0.693, P < 0.01). In the regression model, HKREALD‐30 was positively associated with TOFHLiD (P < 0.05) after controlling for participants’ characteristics. The intra‐class correlation coefficient of HKREALD‐30 was 0.78 and the Cronbach’s alpha was 0.84. Conclusion: Initial testing of HKREALD‐30 suggested that it is a valid and reliable instrument for the basic screening of oral health literacy among Chinese people in Hong Kong. 相似文献

OBJECTIVES: To develop and test the psychometric properties (validity and reliability) of a questionnaire to evaluate clinical dental teachers. METHODS: An item (question) pool was generated with the use of a literature review, feedback from faculty staff, and from focus group discussions with dental students. Following factor analysis the validity and reliability of a revised questionnaire was assessed. This involved 148 dental students and 453 assessments of 29 clinical dental teachers. RESULTS: Effective clinical dental teaching (ECDT) scores were associated with 'global ratings' of the effectiveness of clinical dental teaching (P<0.01), indicating strong criterion validity. In comparison analysis there was strong agreement between students regarding ratings of individual clinical dental teachers, indicating good construct validity. Reliability was assessed by examining internal consistency of sub-scales and overall ECDT scale, and found to be good (Cronbach alpha's > 0.80). CONCLUSION: A valid and reliable measure to evaluate clinical dental teachers has been developed for use in a clinical academia setting, and has potential use as a quality assurance measure. 相似文献
