Tracing Stephanie’s Growth in Image Making through the Pirie-Kieren Lense
DescriptionIn this analytic, Stephanie’s growth in mathematical understanding is presented as she learns in the image making layer of the Pirie-Kieren model for studying the growth in mathematical understanding. Attention is paid to Stephanie’s exploration of the Shirts and Pants task in third grade, and Stephanie’s exploration of the towers problem, building towers of certain heights while selecting form two colors of cubes.
Stephanie builds images as she learns by creating picture diagrams and using letters to represent colors of shirts, building towers and sorting them into patterns, counting up towers, and creating classes of towers based on patterns. Stephanie begins to recognize patterns as she builds towers and creates images that represent processes used for solving the problems.
