Virtual Reality Dog Head: The Effectiveness of VR to Enhance Learning Canine Larynx and Hyoid Apparatus
Teaching the anatomy of the canine larynx and hyoid apparatus is challenging because dissection disassembles and/or damages the structures, making it difficult to understand their three-dimensional anatomy and spatial interrelationships. Two studies were conducted to assess the effectiveness of custom developed mono 3D and virtual reality interactive computerized tutorials for teaching the anatomy of the canine larynx and hyoid apparatus using a randomized control design with students enrolled in the first-year professional program at Oregon State University’s College of Veterinary Medicine.

All students received the traditional methods of didactic teaching and dissection to learn the anatomy of the canine larynx and hyoid apparatus, after which they were divided into two statistically equal groups based on their cumulative anatomy test scores from the prior term. The first study evaluated the mono 3D version containing 3D objects of the canine larynx and hyoid apparatus against a control of the same objects presented as static images. The second study evaluated the virtual reality version containing the same 3D objects against a control of the mono 3D version from the first study.

In each study, groups received identical post-learning assessments and surveys. Post-learning assessment and survey scores were significantly higher among students in the mono 3D group than those in the control group for the initial study. For the second study, post-learning assessment and survey scores were both higher among students in the virtual reality group than those in the control group.

These studies demonstrated that a 3D computerized tutorial is more effective in teaching the anatomy of the canine hyoid apparatus and larynx than images without a tutorial. They also suggested that a virtual reality computerized tutorial may be more effective in teaching the anatomy of the canine hyoid apparatus and larynx than a mono 3D computerized tutorial, but did not reach statistical significance. Students from each study rated their learning experience higher when using the mono 3D and virtual reality computerized tutorial, respectively.
