The overall project "Denken lernen - Probleme lösen" has been expanded in recent years after an initial sub-project in elementary school to include one for the lower secondary level. Schools throughout Austria were provided with the micro:bit and related materials. A training initiative for teachers was rolled out. In this article I would like to present a part of the evaluation results of this project. The investigation covers two aspects: the students' ability to solve problems and the students' opinions and views on working with the micro:bit.
