Résumé
Young children find it much easier to solve concrete partitive division problems when the objects to be shared are grouped by the divisor rather than by the quotient, but the reverse is true in quotitive division problems. In previous research, the objects to be shared were grouped and the perceptual display was slightly different in the Grouping-by-Divisor and Grouping-by-Quotient conditions and this may have contributed to the difference between the conditions. In the study reported here, partitive and quotitive division problems were presented to 5-8-year-olds. The objects to be shared were presented in a grid and the groups were created by verbal instruction; the perceptual arrangement was identical in both conditions. The Grouping-by-Divisor condition remained significantly easier than the Grouping-by-Quotient condition in the partitive problems but the reverse was true in the quotitive problems. This shows that the perceptual arrangement of objects cannot fully explain the difference in difficulty between the Grouping-by-Divisor and Grouping-by-Quotient conditions and also provides support for the notion that young children rely on models that are based on restricted concrete representations when solving division problems.
