On retibne.de, teachers can find freely available teaching materials on the subject of repairs and education for sustainable development for technology and IT lessons. This didactic and methodical preparation of repair tasks for lessons should, on the one hand, help to enable pupils to identify and analyse the sources of faults professionally and to restore the functionality of technical artefacts.

On the other hand, analysing how they work should contribute to a deeper understanding of the complex problems associated with their manufacture, use and disposal. To this end, methods and materials have been developed that address the ethical, ecological, economic and political implications associated with repair and obsolescence in an interdisciplinary manner in the spirit of education for sustainable development.
