Design and Evaluation of a Virtual Reality Model for Skull Anatomy Education

Thesis Abstract

The pedagogical challenges associated with traditional cadaveric dissection and two-dimensional imaging in skull anatomy education necessitate innovative instructional approaches to enhance student understanding and engagement. This study aims to design, develop, and evaluate a virtual reality (VR) model specifically tailored for teaching human skull anatomy, thereby addressing the limitations of conventional methods in providing immersive, interactive, and accessible learning experiences. The primary objectives include developing an anatomically accurate VR skull model using a participatory design process, assessing the model’s usability and efficacy through quantitative and qualitative methods, and comparing learning outcomes between students exposed to the VR model and those receiving traditional instruction. Employing a mixed-methods research design, the study involved a sample of 120 undergraduate medical students enrolled in the human anatomy course at a major university, randomly assigned to experimental (VR-based learning) and control (traditional learning) groups. The VR model was constructed utilizing Unity 3D and Oculus Rift head-mounted displays, incorporating features such as multisensory engagement, interactive dissection, and detailed annotations. Data collection tools included validated questionnaires for usability assessment (System Usability Scale), pre- and post-test examinations measuring anatomical knowledge, and semi-structured interviews to explore user experiences. Validity and reliability of instruments were established through expert review and Cronbach’s alpha coefficients exceeding 0.85. Data analysis involved descriptive statistics to summarize participant demographics, paired and independent samples t-tests to evaluate differences in pre- and post-test scores, and ANOVA for group comparisons. Thematic analysis was employed to interpret qualitative interview data, providing insights into user perceptions and challenges associated with the VR application. The study draws on Cognitive Load Theory and the Experiential Learning Theory to underpin the pedagogical framework, positing that immersive VR experiences can reduce cognitive load and foster deeper learning through active engagement. The anticipated findings suggest that students utilizing the VR model will demonstrate significantly higher gains in anatomical knowledge, exhibit higher usability scores, and report greater motivation and satisfaction compared to their counterparts in the traditional learning group. The model is expected to facilitate improved spatial understanding of skull structures, particularly complex regions such as the cranial fossae and foramina, supported by subjective feedback indicating enhanced visualization and interaction. These results would confirm the potential of VR technology as an effective supplement or alternative in anatomy education, bridging gaps inherent in traditional pedagogies. Consequently, this research contributes novel empirical evidence to the field of medical education technology, especially regarding the application of immersive VR models in complex anatomical learning domains. It fills existing gaps concerning the usability and pedagogical impact of VR models in skull anatomy, providing a framework for scalable implementation. The study advocates for integrating VR-based tools into curricula to complement dissection and lectures, emphasizing cost-effectiveness, safety, and accessibility. Recommendations include refining VR design based on user feedback, expanding the model to cover other anatomical regions, and exploring longitudinal effects on clinical competencies. Future studies should investigate the transferability of VR-acquired knowledge to clinical practice through long-term assessment and interdisciplinary integration, ensuring that technological advancements translate into tangible educational and healthcare outcomes.
