Applying QR Codes in Facilitating Mathematics and Informatics Education

In this volume of the International Journal of Research in E-learning, authors from different countries are trying to answer the following question: what should be the university / school of the 21 st century? Among other things, it should be open to innovation -not only in the world of technology, but also in relation to teaching and learning processes. Personalisation of teaching / learning should take place -a student is in the centre of the university / school of the 21 st century. Another desirable feature is highly qualified staff, open and prepared for lifelong learning. One of the pillars of preparing new generation specialists should be STEM education, internationalisation of higher education, and mobility.
