Gabriela Valverde, Encarnación Castro Martínez

• We present the findings of a study on prospective elementary teachers� proportional reasoning. After describing some of the teachers� performance in solving multiplicative structure problems that involve ratios and relations of direct proportionality between quantities, we were able to establish classifications of their answers according to various categories of proportional reasoning.
