"Why Doesn't It Start from the Origin?": Hearing the Cognitive Voice of Signs
Ferrara, Francesca
International Group for the Psychology of Mathematics Education, 28th, Bergen, Norway, July 14-18, 2004
Starting from a situated cognition perspective, this paper reports on the activity of 9th grade students who are interpreting the shape of a graph arising from the motion of a bouncing ball. In an unfamiliar context, informed by previous knowledge of similar experiments, the obstacle of understanding why the graph does not start from the origin is overcome through an interplay between different signs.
