OBJECTIVE: This study was conducted to establish a baseline DREEM score for a Pakistani private dental college and a private dental college of Turkey, to compare the educational environment as perceived by the dental students’ of the two institutes and provide insight into the aspects of dental education that are in need of improvement.
METHODOLOGY: It’s a cross- sectional, questionnaire based study conducted at Bahria University Medical and Dental College, Karachi (BUMDC) and a private dental college of Istanbul, Turkey between December 2018 and March 2019. The Dundee Ready Education Environment Measure was filled out by first, second and third year undergraduate dental students at both the institutes. Ethical approval was obtained from ethical review committee of BUMDC after consent was taken from the head of the Turkish institute.
RESULTS: Global DREEM mean score of the two institutes was 116.6 ± 20.7. The overall DREEM score of Bahria University was 119.3 ±24.3 while of Turkish dental institute was 113.8±.16.1, with p-value = 0.000. Institutional DREEM depicts a student perception that is predominantly positive. In both the institutes, the perception regarding the social atmosphere (Students’ Social Self Perception) scored lowest as compared to all other domains.
CONCLUSION: Over all the educational environment at both the institutes is satisfactory however this study has highlighted a need for reforms to improve the social and teaching atmosphere. Despite the overall positive trend, the institutes have yet to achieve excellent status for educational environment. One can learn from the Turkish university in terms of how the social atmosphere can be improved, while the Turkish dental college can benefit by implementing a more student centered teaching methodology.

Defined as everything that is part of the academic institute and affects the learning process, educational environment includes infrastructure, teaching methodology, attitude and behaviour of both teachers and
peers.1,2,3 Numerous studies have proven that educational environment is a major determinant of successful learning instruction.4,5,6 The atmosphere of an institute is considered a stronger predictor of academic growth as compared to prior achievement at school.3
It bears considerable consequence on the effectiveness of curriculum and hence skill, motivation and eventual success of the student.7 The acute noteworthiness of this arbitrary component of medical and dental education brought about the need to qualitatively measure it with a reproducible, universally accepted technique.8
Advances in this front led to the development of Dundee Ready Educational Environment Measure (DREEM) questionnaire by a multinational committee of medical educators in 1997.1,9,10 Further research has established it as a globally recognized and validated tool for “measuring’ the perception of learning environment of students at medical and dental institutes.11,12 Culturally nonspecific, it is an inventory of fifty components that focus on five domains of education namely learning, teaching, academic and social self-perception & atmosphere.13 It draws a holistic and comprehensive snapshot of all the domains at work within the educational institute.14 A considerable impact of this inventory is that it makes homogenized comparisons between medical and dental schools of different countries, a possibility, allowing institutes to establish a point of reference for future comparisons.15,16,17 Moreover, it may bring to light areas of concerns that might have been unintentionally left out by the educators.18,19
Bahria University Medical and Dental College (BUMDC), is located in the metropolis of Karachi. Established in 2011, the dental college follows a hybridmodular curriculum and incorporates both traditional and
latest student based teaching methodology. With a teaching history of less than a decade the college is still in its infancy and hence in constant need of rigorous introspection in order to optimize the learning environment. 2 0
Despite its validity as a successful investigative tool for evaluation of quality of teaching, only a handful of DREEM based researches have been conducted in dental colleges of Pakistan and not one international comparison has been made thus far.10
This study was conducted to establish a baseline DREEM score, to juxtapose the educational environment perception of student of the two institutes and provide insight into the aspects of dental education that are in need of improvement.
Permission for the research was granted by the Ethical review committee of BUMDC (ERC 05/2019). It was a cross-sectional questionnaire based survey. Students who had completed one, two or three years of undergraduate dental education at Bahria University Medical and Dental College, Karachi and a private dental college located in Istanbul, Turkey were invited to take part in it between the period of December 2018 and March 2019. Final year students and house officers were excluded from the study. Sample size of 132 students from each institute was calculated, keeping the confidence interval at 95%, margin of error at 0.5%, population size of 200 and prevalence of 50%. Formula used was,
Convenience sampling technique was used. In all, 264 participants were requested to take part in the study. Participation in the study was voluntary. Data from the Turkish private dental college was collected by a faculty member who was selected under Erasmus teaching mobility program from Bahria University to deliver a lecture to dental students of the Turkish dental college. After the lecture, faculty member explicated the purpose and idea of the study, assured confidentiality and took assent before asking the students to fill the proforma. The original English DREEM inventory was translated into Turkish. Validity of the translation was evaluated with a pilot study and the participants of the pilot study were then excluded from the final study. Similarly at our institute, after explaining the purpose of the study and taking consent, 132 original English language DREEM forms were circulated. Anonymity of the process was reassured. A total of 121 students responded from Bahria University and 124 responded from the Turkish dental college.
The DREEM questionnaire was employed to measure educational environment’s perception of the participants. Based on five main domains and a total score of 200, it comprises of a 50-item inventory focused on statements related to the Educational Environment namely Students’ perceptions of learning (SPL) with 12 statements and a total sum of 48, Students’ perceptions of teachers (SPT) having 11 articles and topmost sum of 44, Students’ academic selfperceptions (SASP) with total of 8 statements and a total sum of 32, Students’ perceptions of atmosphere (SPA) comprising of 12 articles and an absolute sum of 48 and
lastly Students’ social self-perceptions (SSSP) with 7 statements and topmost sum of 28. 5- point Likert type scale was employed to collect responses ranging from strongly agree (4) to strongly disagree (0). The nine negative statements were tallied in reverse manner where strongly agree was scored 0 and strongly disagree scored 4. Incomplete questionnaires were excluded from the study. As suggested by McAleer and Roff in their DREEM inventory guide, the total DREEM score was interpreted as follows: total score of 0-50 was considered very poor, 51-100 as an environment with plenty of problems, score between 101-150 was considered more positive than negative, 151-200 as excellent. Individual statement scores < 3.5 was considered real positive, a score of 2.0-3.0 suggested that the item has room for improvement and an average score of <2.0 was considered troublesome.
The data was compiled manually into MS Office Excel Version 2010 spread sheets from both the countries and then into SPSS Version 23. For categorical variables such as nationality, frequency and percentages were presented. Continuous variables such as age and DREEM scores were presented as mean ± standard deviation (SD). To know the significance between Bahria University’s and Turkish dental college students with DREEM score independent sample ttest was applied. For comparison of different level of students with their achieved scores of DREEM inventory Fisher exact test was applied. p-value of <0.05 was considered to be statistically significant.
Response rate of our institute was 91.6% while that of Turkish University was 93.9%. Average age of the Pakistani students was 20.74 ± 1.24 years (18-26) and that of Turkish students was 20.61 ± 1.92 years (17-33) Table 1 mentions the Global DREEM mean score of the two institutes and the combined subscale score. The total DREEM score of our institute was 119.34 ±24.26 while of
Table 1: Overall DREEM score (mean and standard deviation) and total score of DREEM subscales. (Combined score of Pakistan and Turkey)
Turkish dental college was 113.85 ± 16.13. Overall as well as individual institutional DREEM depicts a student perception of more positive than negative (101-150). And the difference between the two institutes is statistically significant, p-value = 0.038 Subscale mean and standard deviation along with their interpretation for both the institutes is displayed in Table 2. The table also indicates the significant differences
between the two institutes.

The study aimed to evaluate what differences, if any, existed between private dental college of Turkey and Pakistan in terms of educational environment as perceived by the students. For this purpose the institutes were evaluated by employing the DREEM questionnaires. It is the first time that such a study is being conducted in either of the institutes. With overall DREEM score of 119.3 ±24.3 for BUMDC and 113.8±.16.1 for the Turkish Institute there appears very little difference in the overall opinion but nonetheless, the difference is statistically significant, p-value = 0.038. Scores in the range of 100 to 150 are considered more positive than negative but with definite room for improvement, as only values above 150 are considered excellent. These values are in concurrence with findings of Khan K et al19, who reported a score of 120 for 4 dental institutes of Rawalpindi, Pakistan and also similar to results reported by Tontus O et al21 of Turkey who stated DREEM score of 107.15/200 for 11 medical faculties in Turkey. Similar scores have been reported for Saudi Arabia1, Iran3 , India23 and other countries of this region. In contrast to these, higher scores were reported by Vanghan B et al. (135.37 ±19.33) in their study9 conducted in University of Melbourne, Australia and by Hongkan W et al24 from Thailand (131.1 ±17.0).
Analysis of the subscales revealed that students of Bahria dental college rated the learning environment as the most positive aspect of their environment, suggesting that the students are generally satisfied with the hybrid curriculum, focused on incorporating student centered practices The most highly rated statements were ‘I feel I am being well prepared for my profession’ and ‘teaching time is put to good use’ which depicts that the institute is ensuring students’ satisfaction when it comes to their future performance. For the Turkish students, the atmosphere of their institute was most highly rated, showing they found the teaching environment relaxed, stress free and overall joyous. Among the highest rated statements were “the atmosphere is relaxed during lectures” and ‘I feel comfortable in class socially’. Both the institutes unanimously declared the social selfperception to be the most neglected category, indicating a need for improvement of effective support system for stressed out individuals.
Analysis of the individual items demonstrated that for the private dental college of Turkey, a shift from teacher centred to student centred approach is needed as the statements pertaining to this this category all unanimously scored less than 2. In this domain BUMDC appears to be on the right track as the students have rated this component to be the
highest among all others subscales.
According to our findings Bahria dental college needs to work on improving its control over cheating during examination as its one of the poorly rated items. Concerted efforts also need to be put into making the overall university experience enjoyable for the students as they most strongly agreed to the statement “I find the experience disappointing”
This study has provided valuable insight into students’ perception of their learning environment and how it compares with another international institute. Secondly, individual
items analysis highlighted specific problems and strengths within each of the dental colleges.
One of the inherent limitations of DREEM questionnaire is that it does not give any details about the underlying reasons for the highlighted issue nor does it suggest solutions
to the problems. Furthermore the DREEM inventory being a predetermined questionnaire might have left out certain factors that impacted our educational setups. Moreover the
sampling techniques employed for this study is voluntary participation and this may have resulted in sampling bias. The self-reporting questionnaire is likely associated with
response bias. Since this study only compared two dental colleges and its results cannot be generalized, further studies should be done in future with more number of institutes participating in order to establish a generalized score. Moreover this study can be conducted again, in the same dental college, at a later point in time to determine the effect
of any changes that the institutes may have made in their educational environment.
This study has highlighted a number of problems that are in need of attention. Both institutes need to reform their educational environment. Even though the overall scores
may be predominantly positive both the institutes have yet to achieve excellent status for all the criteria that constitute an educational environment. Bahria University can learn
from the Turkish university in terms of how the social atmosphere can be improved, while the Turkish dental college can benefit by implementing a more student centered teaching
methodology. DREEM-based surveys are highly recommended for periodic monitoring of the educational environment.
