Area of Science:

  • Medical Education
  • Neuroanatomy
  • Virtual Reality

Background:

  • Three-dimensional (3D) computer graphics are increasingly utilized in anatomy education.
  • Traditional systems often use 2D renderings on standard screens.
  • The Dextrobeam VR environment offers stereoscopic projection for large-group neuroanatomical model presentation.

Purpose of the Study:

  • To compare the effectiveness of a 3D virtual reality (VR) neuroanatomy lecture with a standard 2D presentation.
  • To evaluate student perception and learning outcomes between the two teaching modalities.

Main Methods:

  • Second-year medical students (n=169) were randomized into two groups.
  • One group received a 2D PowerPoint lecture, the other a 3D animated VR lecture using DextroBeam.
  • Both groups completed a multiple-choice exam and a subjective evaluation.

Main Results:

  • The 3D VR group's exam scores were statistically non-inferior to the 2D group (mean 5.45 vs. 5.19).
  • Students rated the 3D VR method superior in spatial understanding, future application, effectiveness, and enjoyableness (p<0.01).

Conclusions:

  • Stereoscopic 3D VR lectures are a valid method for teaching neuroanatomy.
  • This immersive approach is well-received by students, enhancing spatial comprehension.
  • Further research is needed to integrate large-group VR systems into neuroanatomy curricula.
