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

Area of Science:

• Medical Education
• Anatomy Education
• Medical Simulation

Background:

• Traditional 2D anatomical models may present limitations in conveying complex 3D spatial relationships of structures like the inner ear.
• Enhancing medical student understanding of intricate anatomical structures is crucial for clinical competence.

Purpose of the Study:

• To compare the efficacy of 2D versus 3D models in teaching inner ear anatomy.
• To assess the impact of 3D anatomical models on student satisfaction and self-confidence in learning.

Main Methods:

• First-year medical students were randomized into two groups: one receiving a 2D inner ear model presentation, the other a 3D model presentation.
• Student confidence was measured pre- and post-presentation using surveys and the Student Satisfaction and Self Confidence in Learning (SCLS) questionnaire.

Main Results:

• The 3D model group reported significantly higher perceived helpfulness of the teaching model (p=0.0147).
• Statistically significant differences favoring the 3D model were observed in Q1 (p=0.0365) and Q12 (p=0.0308) of the SCLS questionnaire.
• The 3D model group demonstrated increased self-confidence in understanding inner ear anatomy.

Conclusions:

• Three-dimensional models offer a superior learning experience for inner ear anatomy compared to 2D representations.
• Utilizing 3D models in medical education can significantly boost student confidence and perceived learning effectiveness.
