Abstract
BACKGROUND: Knowledge of embryonic development is essential to understand the positioning of organs in the human body. Unfortunately, (bio)medical students have to struggle with textbooks that use static, two-dimensional (2D) schematics to grasp the intricate three-dimensional (3D) morphogenesis of the developing human body. To facilitate embryology education on an understandable and scientific level, a 3D Atlas of Human Embryology (3D Atlas) was created (Science, 2016), encompassing 14 interactive 3D-PDFs of various stages of human embryonic development (freely available from http://www.3datlasofhumanembryology.com). This study examined whether the use of the 3D atlas has added educational value and improves the students learning experience. METHODS: The 3D atlas was introduced and integrated in lectures and practical classes of an existing embryology course at our university for first year biomedical students. By means of a questionnaire the use of the 3D atlas was evaluated. The outcomes in written examinations was compared between cohorts that followed the course before and after integration of the 3D atlas. RESULTS: Our results showed that the 3D Atlas significantly improves students' understanding of human embryology, reflected in significant higher test scores for new students. Furthermore, the 3D atlas also significantly improved repeaters' test scores. CONCLUSIONS: The results indicate that the3D Atlas of Human Embryology facilitates students' learning experience as a resource to support embryology lectures. Students appreciated the use of the 3D atlas in practical classes and liked its interactive aspect. Interestingly, the students also appreciated the physical hand-painted embryological models that were used in addition to the digital 3D atlas during practical classes. The 3D Atlas of Human Embryology has proven to be a valuable resource in addition to the existing resources to teach the intricate developmental processes of human embryology, especially in a blended learning curriculum.
