The aim of the project is to link realia (materials e.g. trees) via QR codes with learning assignments or information in a way that a differentiated learning assignment can be called up according to the level of education (1st gr gets a different task than 2nd gr with the same code). This tool is implemented in existing learning management systems (moodle, lms.at). The aim is to make the learning process more interactive and appealing and to adapt it individually to the abilities of the Vocation
