Kristy Goodwin, Joanne Mulligan and John HedbergSignificant technological change has impacted on the representational modalities employed in mathematics learning. Yet, studies evaluating their impact and efficacy are not entirely unequivocal. This study investigates the unique contribution of interactive, digital technologies in the learning of early mathematical concepts in the first years of schooling. The study describes the pedagogical and technological affordances upon differences in observed learning outcomes. The impact of digital, pedagogical interventions on children?s internalised representations of concepts is explored. Case studies of the development of children’s mathematical representations are presented through the use of digital agents, such as learning objects, interactive whiteboards, and wireless mobile learning devices.
