Kynigos, Chronis; Psycharis, Georgos – International Group for the Psychology of Mathematics Education, 2003
We explore how 13 year-olds construct meanings around the notion of curvature in their classroom while working with software that combines symbolic notation to construct geometrical figures with dynamic manipulation of variable. The ideas of curve as intrinsic dynamic construction, and curve as object with properties related to its positioning on…
