Our main ideas and principles:
- We introduce the technology from the beginning along mathematical tasks. No command - explanations before you get an idea for which task you use it.
- To learn the handling of the technology we offer to you four different
types of technical guide.
You can decide twice:- Do you prefer a short or a long version?
- Do you prefer an electronic or a paper version?
Electronic Paper Short 
This could be- a website with a glossary with two columns:
- I wish to do ...
- How you can do it with the technology
- a film with a sequence of screen shots showing you how to use a certain command
This could be:- doc or/and pdf file with a table like a glossary
with two columns:
- I wish to do ...
- How you can do it with the technology
Long 
This could be:- a film of a sequence of screen shots showing the step wise solution of the task
- a file of the used technology (as TI-Nspire, GeoGebra) with possible solution(s).
This could be:
- doc or/and pdf file with possible step wise solution(s).
- a website with a glossary with two columns:
- We try to use different approaches for all the tasks.
- We offer to you further information about the presented tasks, such
as:
- For whom is the task?
- For which age of students?
- What is the needed knowledge?
- What is the task about?
- What is the main idea?
- Which kind of technology is used?
