Absztrakt (kivonat)

In the German mathematical educational system the graphical calculator is not only allowed but also recommended in secondary grammar school. Therefore in the Deutsche Schule Budapest, where the graphical calculator based on German curriculum is also allowed and required, an experiment were conducted with two groups in grade 10. This experiment was performed in these groups for 46 lectures. The parallel teaching with and without graphical calculator was the main emphasis in the lectures. We consistently used the “old” with the “new” method simultaneously. The aim of the experiment was to determine how the graphical calculator can be helpful in the mathematics courses when it is used for introduction of differential calculus. To apply calculators for mathematical problems secondary-school students have to understand the meaning and the concepts of mathematical formulas confidently, they have to convert and interpret the parameters and substitute them into the right formulas. Besides, they have to know correctly the functions of the calculator in practice. Even better students can have difficulty in using the calculator because they need different notations on paper and booklet operation and on the software or graphical calculator. While it has been suggested that appropriate use of the graphical calculator can support students in differential calculus, the following issues were considered: how and how deep the differential calculus should be instructed with and without graphical calculator so that the students can build the right concept image.
