Determining optimal learning conditions for acquiring spatial 3D information using computer‐based anatomical reconstructions

Abstract

Interactive stereoscopic 3D digital models of head and neck structures, generated from CT scans of a male cadaver, have been developed. The display and interactive features of the models will be used to determine optimal conditions for acquiring 3D information for individuals with different spatial abilities. A pre‐mental rotation test will be used to determine participants' spatial ability. Based on pre‐test results, participants will be assigned to either the high or low spatial ability group. Members of each group will be further divided into four subgroups based on four learning conditions. A stereo/high‐interactive group will study anatomy using stereoscopic models and will have active control over the pace and direction of the model. A non‐stereo/low‐interactive group will examine anatomy with 2D images and restricted interaction. A stereo/low‐interactive and non‐stereo/high‐interactive group will study the same anatomy in corresponding conditions. Learning will be assessed by 50 multiple‐choice questions that require mental manipulation of internalized 3D anatomical representations. The results of this study will aid the design and implementation of effective 3D computer visualizations to help students comprehend the spatial 3D organization of the human body, while accounting for individual differences in spatial abilities.Grant Funding SourceInternal
