The Fifth International Conference on Technology in Mathematics Teaching (ICTMT 5)
will be held at the University of Klagenfurt; Aug 6-9, 2001.
It is the plan of the organizers, to structure the submitted more lecture type papers into strands which each have a renowned speaker as a leading "figure".
Moreover, to offer a plenty of discussion and group work, there will be a number of special groups and working groups organized.

Schedule and abstracts

For any enquiries relating to this strand, please do not hesitate to contact the chair.If your contribution should fit to this strand, please also contact the chair: garbayo@eucmos.sim.ucm.es

Plenary talk: Eugenio Roanes Lozano, Madrid:

Co-operation Between Dynamic Geometry Systems and Computer Algebra Systems
- Investigating, Guessing, Checking and Proving with the computer

Software is usually classified according to the purpose of the different packages and languages. The types of software most frequently used in Maths education (if we exclude Statistical Packages) are:

• Computer Algebra Systems (like Maple, Derive, Mathematica, Axiom, Macsyma, Reduce, Mupad...) and
• Dynamic Geometry Systems (like the Geometer's Sketchpad, Cabri Geometry, Cinderella, Euklid, Dr. Geo, WinGeom...).
• The TI-92 calculator offers both types of software.

Computer Algebra Systems (CAS) and Dynamic Geometry Systems (DGS) complement each other, offering two different approaches to mathematical knowledge (the "algebraic" approach vs. the "rule and compass" approach.

This session is devoted to Maths education using both technologies. For instance the topic of the plenary session is the co-operation between both technologies in order to treat with the computer the whole mathematical process of discovery or re-discovery: Investigating ---> Guessing ----> Checking ----> Proving.

But many lines of research fit within this session, for instance

• Co-operation between CAS and DGS.
• Extensions and possible developments of CAS and DGS in order to match the necessities of the Maths class.
• How to use CAS and DGS in the Maths class.
• Classroom experiences and materials using CAS and DGS.
• DGS and CAS in Maths curricula.
• ... Observe that the topics of the session are not restricted to the list.
