Which concepts can teachers use to inspire their classes for the so-called STEM subjects, that is science, technology, engineering and mathematics? The Nordmetall Foundation, which is particularly committed to schools in the state of Bremen, honors the STEM school together with partners. STEM stakeholders from Bremen and representatives of the Foundation have now met at MARUM to certify the schools. The Oberschule Oberschule in den Sandwehen was again certified as a STEM school, the Gerhard-Rolfs-Oberschule, the Wilhelm-Olbers-Oberschule and the Oberschule Koblenzer Straße. New in the network of excellence STEM schools Bremen is now the Oberschule Rockwinkel.
