“…These approaches enable efficient and consistent content coverage; however, images often fail to capture the three‐dimensional shape of the structures depicted or show dynamic developmental change (Carlson, 2002; Math and Mahgerefteh, 2018). Although animations and videos can show developmental processes in action (Lowrie et al, 2007; Beale, 2010), few accurate animations are available, and these rely upon passive visual learning.…”

Knowledge of embryology is foundational for understanding normal anatomy and birth defects, yet, embryology is a notoriously difficult subject for medical students. Embryonic lateral folding in particular is one of the most challenging concepts in embryology. Highly effective teaching methods that promote active engagement with dynamic, three-dimensional models may be helpful for teaching this content. The aim of this study was to determine whether a hands-on modeling activity utilizing premade crocheted pieces constructed from durable, inexpensive yarn helped medical students enrolled in a pre-matriculation course to understand embryonic lateral folding. Change in knowledge was assessed using a pre-post design. Students also completed subjective evaluations regarding their satisfaction with the activity. Quiz scores in means (±SD) increased from 62.7 (±24.1) % before the activity to 77.0 (±17.1) % after the activity (P = 0.0495, two-tailed paired t test; d = 0.68). Generally, students reported that the activity was helpful and enjoyable, and the model pieces were easy to manipulate. These promising results suggest that hands-on activities with dynamic, three-dimensional models constitute an effective method for teaching embryology. Anat Sci Educ 14: 666-674.
