In a friends school in Denmark the teacher could decide that your family had to host a party for all the kids at the family home, so they could get to know each other better, and that was repeated until all involved parties stoped misbehaving.

The canning would vastly shorten the time span on which all parties stop misbehaving while the bullying continues. I was bullied as a kid and the school didn't do anything. When my father tried to reason with the bully's family he discovered they were just awful, violent people, bullies, all of them. When he came home, frustrated, he sat me and said something like "uhm, well, ok, listen, I went to talk to the boy's parents and... well... the next time he bothers you just beat the shit out of him. I'll deal with the school" and the quoted the motto of my country: "by reason or by force". Some things just works faster than diplomacy and all shit get sorted out without extending the suffering for most parties involved.
Good when all parents are able to host such party. I would say that in Poland, most of parents with a misbehaving kid are barely able to throw a party for their kid and several of his/her friends. Many times people complain about the cost of school supplies for their kids already.
