Animated teaching improves student learning of human gastrulation and neurulation.

Human embryology is a complex topic that brings together core components of anatomy and physiology to describe the developmental process from fertilisation to birth. Embryonic development is a challenging topic of study that is core to the curricula for health science students. There are challenges ingrained in teaching and learning embryology, due to the three-dimensional dynamic processes that occur as the embryo develops. This study aimed to develop and assess two newly developed animations depicting key processes in embryology, namely gastrulation and neurulation, as supplemental learning aids for students. Indeed, animated teaching tools to enhance the learning of gastrulation and neurulation are not widely available. A multi-disciplinary team of physiologists, biochemists, anatomists, and a computer scientist developed the animation sets. A student cohort of 81 first-year health science students were enrolled in this study over a period of three academic years. Both animations are in line with the course content of the first-year health science students undertaking the Human Health and Disease BSc at Trinity College Dublin, who were the study participants. Participants were randomly assigned to a non-animation control group and an animation group. Each set of animated teaching aids was broken down into individual clips which were given identifiable headings to allow the user to interchange between clips to facilitate a more personal learning experience. The animation group had open access to the animations for a three-week period. Questionnaires were designed to assess participants' attitude to the animations and their knowledge of embryology, both at the start of the study and three weeks later following access to the animations. Data presented herein indicate that students incorporated the animated teaching aids into digital home study and that the use of the animations acted as a supplemental tool that increased student knowledge in key areas of human embryology. From a qualitative point of view, students described the animations as enjoyable and helpful in visualising complex processes. This study indicates that the development of gastrulation and neurulation animated learning tools allow for a more engaging learning experience, facilitating student's engagement with academically challenging concepts in human embryology.
