3D Modalities for Medical Student Education of Congenital Heart Disease

The goal of this clinical trial is to learn if 3D-printed heart models and augmented reality can be useful modalities to teach medical students about congenital heart disease. The main questions it aims to answer are: 1. Does using 3D-printed heart models improve learners' understanding of congenital heart disease when compared to traditional slide-based teaching methods? 2. Does using augmented reality heart models improve learners' understanding of congenital heart disease when compared to traditional slide-based teaching methods? 3. How can these modalities best be integrated into standard medical school curricula? Participants will: 1. Take a pre-test consisting of questions regarding anatomy and physiology of the normal heart as well as two congenital heart diseases. 2. Be randomized into 3 groups that receive a teaching session using either slide-based lecture, 3D-printed models, or augmented reality. 3. Take a post-test of the same questions from the pre-test. 4. Take a delayed post-test of the same questions with additional subjective questions about their experience with their assigned modality.
