The Qualitative Grapher is developed by the Concord Consortium and informed by previous work of several authors, including Michal Yerushalmy, Beba Shternberg and Judah Schwartz on The Function Sketcher, and James Kaput on SimCalc. The Qualitative Grapher presents a Cartesian playground to explore graphs and models of motion and change without quantitative values. Graphs built by users using straight and curved linear elements determine the vertical motion of an object.
Innovative technology developed by the Concord Consortium permits networked users of our software to save with one click an image of any screen made with CC interactive software. They can then share their work with other networked users in real time or asynchronously.
