Baccaglini-Frank, Anna; Mariotti, Maria Alessandra – International Journal of Computers for Mathematical Learning, 2010
Research has shown that the tools provided by dynamic geometry systems (DGSs) impact students' approach to investigating open problems in Euclidean geometry. We particularly focus on cognitive processes that might be induced by certain ways of dragging in Cabri. Building on the work of Arzarello, Olivero and other researchers, we have conceived a…

Herbert, Sandra; Pierce, Robyn – International Journal of Computers for Mathematical Learning, 2008
Does speed provide a "model for" rate of change in other contexts? Does JavaMathWorlds (JMW), animated simulation software, assist in the development of the "model for" rate of change? This project investigates the transference of understandings of rate gained in a motion context to a non-motion context. Students were 27 14-15 year old students at…

Parnafes, Orit; Disessa, Andrea – International Journal of Computers for Mathematical Learning, 2004
This paper examines the idea that particular representations differentially support and enhance different cognitive processes, in particular different types of reasoning. Five case studies were conducted consisting of detailed observations of pairs of middle-school students interacting with a computer-based learning environment. The software…
