The technical training for students on the (teacher training) technology degree programme in the Technical Education working group includes a variety of practical skills to enable them to design technology lessons with pupils in school technology rooms later in their careers and is carried out in the working group's own workshops.

The previous experience in craftsmanship for this varies greatly at the start of the programme, as some students have completed an academic appointment and others have not. This is clearly noticeable in the workshop module. While students with previous experience can combine skills they have already acquired, other students cannot. As a result, students require very different levels of support, which is a major challenge for teachers, even in small groups. In addition, the acquired skills are only needed again a few semesters later in the advanced modules. To date, there has been a lack of support concepts for the very different individual abilities to reactivate these skills.

This is where the SelTecAR project (self-directed learning in technical education using augumented reality) comes in. The project's contribution to solving these two challenges is to support self-directed learning processes in the acquisition of practical skills with an augmented reality environment precisely at the time and place of learning. In other words, when the use of new tools and machines needs to be learnt or mastered.

Self-directed learning with AR support takes place both during the initial acquisition of skills and when refreshing past learning outcomes in higher semesters. The AR environment can be accessed using your own smartphone. Accessing this support is low-threshold and available to all students at any stage of their studies.
