Nemirovsky, Ricardo; Ferrara, Francesca; Ferrari, Giulia; Adamuz-Povedano, Natividad – Educational Studies in Mathematics, 2020
This paper focuses on the emergence of abstraction through the use of a new kind of motion detector--WiiGraph--with 11-year-old children. In the selected episodes, the children used this motion detector to create three simultaneous graphs of position vs. time: two graphs for the motion of each hand and a third one corresponding to their…

Noble, Tracy; Nemirovsky, Ricardo; Dimattia, Cara; Wright, Tracey – International Journal of Computers for Mathematical Learning, 2004
In this article, we will describe the results of a study of 6th grade students learning about the mathematics of change. The students in this study worked with software environments for the computer and the graphing calculator that included a simulation of a moving elevator, linked to a graph of its velocity vs. time. We will describe how the…
