Development of effective 3D digital models for first-time learners of musculoskeletal anatomy

Musculoskeletal anatomy is a critical component of allied health curricula. With the ubiquity of technology in the classroom and the recent COVID-19 pandemic creating accessibility barriers for students, there is a need for viable digital resources to enhance learning by supplementing traditional textbook studying. This article describes the creation of an annotated, interactive, three-dimensional digital model and presents preliminary data on its effectiveness for students learning musculoskeletal structures of the hip and knee for the first time. The 3D model was developed in Blender using open-source files and was uploaded to the Sketchfab platform. Eighty-one students in the musculoskeletal anatomy course at a large midwestern university took an assessment to measure their baseline anatomical knowledge, studied the testable structures from either the model or textbook images for 10 min, and took a follow-up assessment. Students in the 3D Model Group saw greater increases from their baseline scores and also reported higher confidence in what they had learned, increased ability to visualize anatomical structures, and greater enjoyment of their resource than students who used textbook images. The findings presented here suggest that creating effective, accessible 3D digital resources is feasible for educators without training in technology-related fields and that having access to these resources can be beneficial to first-time learners of anatomy.
