Symmetry detection in early childhood as a foundation for spatial and STEM development

Abstract: Early spatial skills in children predict future mathematical and STEM performance. This study investigates 4- and 5-year-old children's (N=41) detection of symmetry transformations using simplified coloured magic squares. We examined recognition of invariance through rotations and reflections with visual tasks and tissue paper activities. ANOVA results indicate that rotational symmetry was stable across ages, except for 270° rotations, which showed improvement at age five. In contrast, reflectional symmetry showed significant gains, particularly along vertical and horizontal axes. These findings suggest that reflection tasks demand greater cognitive effort than rotations. Early educational experiences should therefore gradually introduce rotational activities before reflections to lay the groundwork for developing spatial abilities and symmetry reasoning. This study also supplements recent discussions on the pedagogical significance of spatial, hands-on learning in early STEM education.
