Using technology in maths lesson it is possible to introduce new tasks.
One example for mathematical questions, that can be explored dynamically
with different approaches, is the following:
Three intersection points with the horizontal axis of a rational function
of degree 3 are given.
Construct the tangent at the midpoint of two zeros of the function f. What
do you notice?
Using technology in maths classrooms enables much more
interaction between students

.
Different mathematical representations
can be used interactively by integrating CAS technology.
This can be demonstrated
with the following film, which shows a possible solution of the given problem.

Technical guide
Here you can find some hints
if you want to solve this problem by using technology. You have different
kinds of hints to pick up ones which suit you best.

Rich instructions
We also try to provide you with different types of instructions that can
be used. So there are
paper based
instructions
,
screencasts
as well as HTML pages which show with the help of
technology we can provide
very rich
instructions
to students. On the left side there is a screencast
with precise instructions and on the right side, there is an applet
where students work [following the left side instructions].
