Abstract
This study investigates the structure and development of quantitative thought in Greece and India. A total of 297 Indian subjects and 269 Greek subjects, aged from 10 to 16 years, were examined by a battery addressing their ability to execute arithmetic operations, a battery addressing their proportional reasoning, and a battery addressing algebraic reasoning. The items in each battery addressed four developmental levels. Confirmatory factor analysis showed, as predicted, that the same model is able to account for the performance of both cultures. Some differences were observed in the relative strength of the various abilities. However, the developmental inter-patterning of abilities was generally the same in the two cultures. There were no differences in capacity-dependent sequences but there were some differences in strategy-dependent sequences. These findings are discussed in the context of our theory of cognitive development.
