Rumiati, Rumi; Wright, Robert – Mathematics Education Research Group of Australasia, 2010
An assessment approach from Mathematics Recovery was used to document the number knowledge of 20 first-graders and 20 second-graders in an Indonesian school. Sixteen first-graders were at the advanced-counting-by-ones stage and fourteen second-graders were facile. As well, fifteen first-graders and eleven second-graders were at the level of an…

Meron, Ruth; Peled, Irit – International Group for the Psychology of Mathematics Education, 2004
This study investigated the development of an additive schema from the perspective of the schema's flexibility in coping with new context and unfamiliar semantic structure. It followed 27 first graders who learned addition and subtraction using an experimental curriculum. The instruction involved a didactical model combining the context of two…

Mulligan, Joanne; Prescott, Anne; Mitchelmore, Michael – International Group for the Psychology of Mathematics Education, 2004
In a descriptive study of 103 grade 1 children, including 16 longitudinal case studies, we investigated the use of mathematical structure across a range of mathematical tasks. Children's structural development was inferred from their imagistic representations, supported by analysis of problem-solving behavior during videotaped task-based clinical…
