As the new school year begins in Germany, the biggest problem is still the nationwide shortage of teachers. This could be remedied, for example by employing career changers, having larger classes, and using more hybrid lessons (partly online). But this increases the risk that the existing teachers may suffer illness or even resign and makes the general atmosphere and conditions for the students to learn well in lessons more challenging. In addition, due to measures introduced during the Covid crisis, learning deficiencies and mental illnesses have increased significantly among children and young people. The fear of being infected by Covid has now been replaced by fears about climate change and the apocalypse (the world coming to an end). These take away motivation and willingness to learn. The building of a world for tomorrow requires not only discipline, but above all a vision.
