Educators often use concrete objects to help children understand mathematics concepts. However, findings on the effectiveness of concrete objects are mixed. The present study examined how two factors-perceptual richness and established knowledge of the objects-combine to influence children's counting performance. In two experiments, preschoolers (N = 133; Mage = 3;10) were randomly assigned to counting tasks that used one of four types of objects in a 2 (perceptual richness: high or low) × 2… CONTINUE READING
