ab: The TI-89/92’s Data/Matrix-editor is an excellent tool to support
concepts of accumulation points, limits, continuity, average and
instantaneous rates of change. Some steps can be done using a
spreadsheet, too. But very soon we miss the comfortable use of
functions and much more important the computer algebra. In this paper
we focus on the use of handheld technology, because we experienced the
advantage of the overall and anytime availability of these small
machines. The author tried the same approach with a calculus class in
the PC-lab using Derive$^{TM}$. (author’s abstract)
