Understanding the Vestibular Apparatus: How 3D Models Can Improve Student Learning

The objective of this study is to compare student satisfaction and confidence following a presentation of the inner ear anatomy using either a 2D model or a 3D model. First-year medical students were randomized to a 2D or 3D teaching group and given a presentation on the inner ear. Students were surveyed on confidence levels pre- and post-presentation, helpfulness of the presentation, and completed the student satisfaction and self confidence in learning (SCLS) questionnaire. 30 first-year medical students participated in the study: 14 in the 2D model and 16 in the 3D model group. A statistical significance was found between the 2D and 3D group regarding the helpfulness of the model (p = 0.0147), Q1 of the SCLS questionnaire (p = 0.0365), and Q12 of the SCLS questionnaire (p = 0.0308). The use of a 3D model of the inner ear aids in student self-confidence regarding the material and is perceived to be helpful with learning the material.
