Abstract
Research into the impact and effectiveness of handheld technologies in the teaching and learning of mathematics shows signs of having matured over the past few years. This ?coming of age? will prove useful in the years ahead. Significant developments in the nature and purposes of the technology demand new questions and new approaches from those that would chart a course for others to follow in their effective uptake. This paper addresses some of these new questions and approaches within the context of the tools that drive them. It proposes a research agenda which is mindful of previous ?blindspots? as well as some new imperatives imposed by radical developments in the technology itself.
