Abstract

Open peer commentary on the article “Elementary Students’ Construction of Geometric Transformation Reasoning in a Dynamic Animation Environment” by Alan Maloney. Upshot: Parnorkou and Maloney describe how a dynamic animation environment, Graphs ’n Glyphs, supported fourth-grade students’ understandings of translations and rotations. Two elements were critical in their teaching experiment: the design of the software and tasks. This commentary focuses on the decisions that they made and possible implications they had for students’ reasoning.
