Pupils of the secondary school Maria-Ward in Deggendorf could acquire the necessary know-how within the elective course „App-Inventor“. This elective course was implemented by a team of the University of Applied Sciences Deggendorf and some collegues of the STREICHER division electrical engineering. Previously Theresa Eder, Marco Marx, Joel Pokam and Sebastian Zeitel attended a workshop to become familiar with the programming tool „App-Inventor“. Then, on a couple of afternoons, they had the possibility to share their knowledge and a lot of tricks to 18 pupils of the classes 7 to 9. The tutors were excited about the great interest of the pupils and their artistic zeal in using mobile phone and computer. This campaign was initiated by the MINT network of the MINT region Lower Bavaria.
