Abstract

A 10-week study investigated children's ability to infer object cross-sectional shapes (3D to 2D) and reconstruct objects from cross-sections (2D to 3D). Results revealed positive correlations between cross-sectional problem performance, spatial ability and math scores. These correlations were stronger for cross-section inference than object reconstruction. Some children excelled at inferring cross-sections but struggled with reconstruction, while others showed the opposite pattern, suggesting these abilities are distinct. The study indicates that children's capacity for 3D to 2D transformation, rather than 2D to 3D, is more closely linked to their spatial and mathematical abilities. These findings contribute to our understanding of spatial reasoning development in children and have implications for educational approaches in geometry and spatial cognition.
