Abstract
We examine the educational possibilities afforded by new connections
between physical and simulation-based data to build intimacy with
function representations. Historically, technology was first used to
facilitate actions within notations, then to link them, eventually bidirectionally.
Yet recent data strongly indicate that students' difficulties
with interpreting and productively using mathematical notations
continue. We suggest that students need phenomena expressive linked to
the notations, and secondly, that students themselves should be immersed
in generating such phenomena.
