Resumen
The study analyses the influence of multiplicative relationships between quantities, and its discrete or continuous nature in the development of primary school students' ability to discriminate proportional from additive situations. Results have shown that multiplicative relationships between quantities affect significantly primary school students' performance in both situations. However, the continuous or discrete nature of quantities only affects students' performance on proportional problems. Moreover, implicative statistical analysis shows the independence of students' performance on proportional and additive problems. These findings underline the complementarity of understanding proportional and additive relationships in developing the conceptualisation of the notion of ratio as a new unit.
