Learning anatomy: do new computer models improve spatial understanding?

Abstract

Desktop computer models that rotate in virtual 3D space allow for many non-traditional viewpoints of objects. This study sought to determine whether providing more views of the carpal bones improved understanding of their spatial characteristics. Forty-nine first-year medical students entered a randomized controlled trial conducted over 1 1/2 hours on computer workstations. Spatial learning with a computer carpal bone model horizontally rotating at 10 degree views (MV), was compared with the same model rotating at 90 degree views (KV). The main measure of spatial learning was 36 created multiple-choice items. There were no significant differences in spatial learning between MV and KV. It is possible that virtual 3D models that provide multiple views of anatomical objects may be no more effective in teaching spatial relationships than standard views that appear in any anatomical atlas. The benefits of new computer models should be better outlined before more resources are spent on their development.
