Schulpflicht and Schulzwang mean compulsory schooling.
Unerzogen and eine schulfreie Kindheit mean home schooled/unschooled and childhood without school respectively.
A great slogan: Der Schulzwang wird fallen wie die Berliner Mauer...Compulsory schooling will collapse like the Berlin Wall.
That's enough vocab for today!!
Don't worry if the sentences are too long and overwhelming, just skip to the start of the next paragraph, or read the slogans at the side.
Best wishes to the other rusty German speakers out there.
