Abstract

Two teachers in different schools participated in a research project looking at the use of technology based representations of mathematical objects. Each used the same software, incorporating a novel representation of fraction as a dynamic functional relationship between values on two number lines. They planned together, discussing the characteristics of the software, the educational goals and modes of use as well as sharing resources and ideas about student tasks. In practice, the lessons each taught were very different and the ways in which students made use of the software also differed substantially. Influences on the nature of teachers’ incorporation of new elements into their pedagogic practice are discussed, including consideration of explicit and implicit theoretical frameworks and of institutional and cultural contexts.
