Folgende Bereiche könnten interessant sein:

• Wiki für Schüler:innen
• Wiki für für Eltern und Sorgeberechtigte
• Wiki für Lehrkräfte und andere Mitarbeitende

Besonders hilfreich ist sicherlich die Suchfunktion, mit der das ganze Wiki durchsucht werden kann.

Dieses Wiki befindet sich noch im Aufbau. 😁
