During the winter break, educators developed their teaching workshop in the trainings at RODN ‘WOM’ in Częstochowa. On 19th and 21st February, 2019 they took part in workshops dedicated to using QR codes in foreign language classes. The participants stepped into their students’ shoes and solved some coded tasks. They also learnt to generate QR codes in order to create language challenges for their students. They got familiar with a lot of ideas how to use coded information in foreign language classes. The trainings took place in the atmosphere of study and fun accompanied by new technologies.
