During seven chemistry lessons students from grade 9 and 10 conducted three chemical experiments. They used the calculator TI-Nspire and different sensors for recording data and providing the corresponding graphs. Central aims of the study were to find out what students think about the use of the hardware and software, what advantages and disadvantages they see and how useful the obtained graphs are for them to interpret the experiments and find out general rules. The study included 350 pupils from 7 different schools in 4 different federal states of Germany.

The study was carried out in cooperation of Prof. Dr. Rebekka Heimann from the University of Leipzig, Mr. Frank Liebner from the Löbau High School, the German T3 Project and Texas Instruments.
