Young Children Reasoning about Symmetry in a Dynamic Geometry Environment
Oi-Lam Ng; Nathalie Sinclair
ZDM: The International Journal on Mathematics Education Vol. 47, No. 3 (June 2015) pp. 421–434
In this paper, we investigate children's learning of reflectional symmetry in a dynamic geometry environment. Through a classroom-based intervention involving two 1-h lessons, we analyse the changes in the children's thinking about reflectional...

"Area without Numbers": Using Touchscreen Dynamic Geometry to Reason about Shape
Oi-Lam Ng; Nathalie Sinclair
Canadian Journal of Science, Mathematics and Technology Education Vol. 15, No. 1 (2015) pp. 84–101
In this article, we report on two lessons aimed at introducing junior high school students to the idea of shearing in a touchscreen dynamic geometry environment. By using shearing, we hoped to shift students' attention away from a formula-driven,...
