Spatial language and ability play important roles in children's cognitive development. Spatial ability in kindergarten predicts achievement in reading, math, science, and technology in primary school and therefore constitutes an important skill set in preparation for school entrance. Good spatial thinking skills are required for learning in school. The study's purpose was to examine the contribution of robot programming to an intervention aimed at promoting spatial language (spatial vocabulary) and spatial ability (mental rotation, visual-spatial memory) among preschool children at risk for Specific learning disability (SLD). The sample of 84 preschool children participating in the study was randomly assigned to three groups: (1) intervention group with robot programming, (2) intervention group without robot programming, and (3) a control group. The findings indicate that children exposed to the robot-based intervention exhibited the greatest improvement in spatial vocabulary and mental rotation tests when compared to the children who participated in either the intervention without robot programming or in the control group. No significant differences between the groups were found in post-intervention visual-spatial memory. The findings indicate that robot programming activity contributes unique added value in attempts to foster spatial vocabulary and mental rotation.
