Abstract
This paper reports ongoing research on mental processes in early algebra. Two Year 7 classes were each taught with the aim of developing an understanding of algebraic generalizations which included the distributive law. One class used arithmetic examples leading to generalizations. The other used an objects-and-containers model to assist. Significantly better gains were recorded by the latter class on attitudes and content-specific achievement. No significant differences were detected before the teaching intervention for these mixed ability coeducational classes. The evidence points to the likelihood that the use of a concrete analogue assisted cognitive development.
