Description: To understand how students construct mathematical ideas in "Dynamic Geometry" environments (tools like Geometer's Sketchpad and Cabri), one needs clear characterizations of the mathematical "raw materials" embodied in the software and how students use them. What are the mathematical objects and allowable transformations? Which of these do students actually encounter? Which do they notice and attend to? How do they interpret what they notice? Project reports, transcripts of interview data, and sketches used in the research are available on this site.
