Abstract
This article was migrated. The article was marked as recommended. We have changed the medical educational environments which included educational curricula, medical staffs, facilities and teaching and learning methods to improve the academic achievement of medical students and to develop good doctors in schools. Medical students have complaints with their educational environments. Dundee Ready Education Environment Measure(DREEM) consists of five domains; students' perceptions of learning, students' perceptions of teachers, students' academic self-perception, students' perceptions of atmosphere. Using DREEM, the overall mean DREEM score of our school was 106.98 and low to that of Korean medical schools and developed countries. Medical students acknowledged that the domains of teachers and academic self-perceptions were positive. Through the students' perception, the changes of the educational environment might be needed continually to get good academic achievement of medical students.
