Abstracts:

Piotr Bialas, USA:

Linking Graphing Calculators to the Internet (LGCI)

LGCI increases access to the numerical data files, provides no need to type the data into the graphing calculator, and makes possible that the selected data files may be used for Excel, Minitab, SPSS, and many other statistical software products. The TI-83 example of the data transfer will be demonstrated. Participants will be provided with written materials about data transfer to the TI-83/TI-89 graphing calculator.

Piotr Bialas, USA:

ANOVA with the TI-83 Graphing Calculator

This presentation will demonstrate how the Catalog and cut-and paste utilities of the TI-83 graphing calculator can be used to complete a one-factor ANOVA table. The worksheet including two examples will be distributed. Extension may include Two-Factor ANOVA such as 2X2, 2X3, or 3X3 factorial designs. (Hands-on session with the participants using TI-83 graphing calculator suggested.) The presenter will share a handout for the TI-89 graphic calculator if needed.

Jan Kaspar, Czech Republic:

Programming as a tool for the precision

Using the TI-83 graphing calculator I would like to demonstrate how programming requires precision in step-by-step description of mathematics tasks.

Regis Ockerman, Belgium:

Probability simulation with TI-83

Taking advantage of the possibilities of the TI-83, it's easy to do simulations, dealing with problems of probability. In this workshop, we will use programs for those simulations. This will be done in a way, that you can also use these things in class.

Jarmila Robova, Czech Republic:

Graphic solutions of equations and their systems

The contribution deals with using graphing calculator TI-83 in teaching of algebra in secondary school. Several techniques of graphic solution are presented (geometric representation of problems, boolean function, graphic substitution).
