Young Children's Understanding of Geometric Shapes: The Role of Geometric Models
Elia, Iliada; Gagatsis, Athanasios; Kyriakides, Leonidas
International Group for the Psychology of Mathematics Education, Paper presented at the 27th International Group for the Psychology of Mathematics Education Conference Held Jointly with the 25th PME-NA Conference (Honolulu, HI, Jul 13-18, 2003), v2 p349-356
In this paper, we explore the role of polygonal shapes as geometrical models in teaching mathematics, so as to elicit and interpret children's geometric conceptions and understanding about shapes. Primary pupils were asked to draw a stairway of figures (triangles, squares and rectangles) each one bigger than the preceding one. Pupils use two different strategies to tackle this task: (a) conservation of shape by increasing both dimensions of the figure and (b) increasing mainly one dimension of the figure. Each strategy seems to reflect a different way of reasoning, possibly corresponding to a different level of development in geometric thinking. Implications of findings for teaching geometry are discussed. (Contains 4 figures.) [For complete proceedings, see ED500859.]
