The Linear Transformer is developed by the Concord Consortium and informed by previous work on the Calculus Unlimited by Michal Yerushalmy, and Judah Schwartz. The Linear Transformer explicitly ties changes a user makes in a graph of a linear function with corresponding changes in its symbolic expression. Novel features include the capacity to view the symbolic form of the linear function in either slope-intercept or point-slope forms, reflect about both x- and y-axis with associated changes in symbolic form, and model the motion of an object whose vertical position is defined by values on the y-axis and whose velocity is defined by the values on the x-axis.
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.
