An insight into student understanding of functions in a graphing calculator environment

The teaching of functions plays a key role in the secondary mathematics curriculum. Electronic technologies afford deepening student understanding of functions by linking multiple representations. Findings from my previous research which investigated the understanding of functions by students in their final two years of secondary school whilst immersed in a graphing calculator learning environment will be presented and discussed. In the RITEMATHS project I am extending this research to consider a range of technologies and how teachers and students can realise the range of affordances offered by these technologies to support the teaching and learning of functions in a multiple representation environment.
