Rupert Heindl and Daniel Pittich contributed an impulse lecture at the "Schulleiter:innenendienstbesprechung" on 21.06.2022 at the invitation of the government of Lower Bavaria. Based on the lecture with the title "How teaching and school development (can) go hand-in-hand..." interesting discussions and exchanges take place. In addition, new contacts were made for possible perspective collaborations. Thank you very much for the invitation and the open exchange. It was very enriching.
