Keywords:

Research studies (e.g. Vinner, 1989) have shown that students’ mathematics
understanding is typically analytic not visual. The use of multiple
representations (visual and analytic) of mathematical concepts, in instruction
can be beneficial for to students develop conceptual understanding of
mathematics. The process of calculating the derivative f’ of a given function f
is called differentiation. The graph of f’ can often be sketched directly from
that of f by visualizing slopes, a procedure called graphical differentiation.
In this poster presentation, authors will share the results of graphical
differentiation activity done with ClassPad300+. We have tried activity with
high school students and will share the results in detail. The results revealed
that graphical differentiation have a positive effect on students understanding
of differentiation concept compare to those received traditional instruction
