Summary:
Experiments carried out by students are very motivating and lead them to a better understanding of principles and processes in sciences. The main objective is to find functions fitting best to the experimental data and to interpret the special values of the parameters of these functions. The students have to combine knowledge about the different types of functions with the knowledge about chemical and physical facts. As an additional aspect, the students also have to take care of the accuracy in working for obtaining good results. The collection of large lists of data is supported by the TI-CBL system. Mathematical experimenting, complicated mathematical computations and visualization are supported by the TI-92.
We report about first experience of CBL/TI-92 within the final exam at an Austrian grammar school. Basic skills for making experiments, documenting results and using and transferring basical knowledge are discussed in this presentation.
In this presentation we will report about the experiences made with students at the age of 17 to 18 carrying out experiments in chemistry and physics in science courses. We concentrate on how the students can apply their knowledge from mathematics and sciences in these practical situations and how they document their results.
