| An investigation into the role manipulatives play in helping middle school students transition from two-dimensional (2D) geometry to three-dimensional (3D) geometry. Parvate and Hosking's Java applet simulates a square piece of paper: choose how much of its corners to cut away, and it calculates the volume of the box formed by folding its edges upwards. From "How it helps," download Microsoft Word documents of field test write-ups that detail the visualization, empirical validation, scaffolding of formalization, and other outcomes that emerged from the kinesthetic input, group collaboration, and conversation. The authors envision "the design of an entire geometry curriculum taught through the building of a collaborative artifact.... [the prototype of which] is the generation of a 3D puzzle of the Trans America building." | |
