It is not "discipline in class" but about a positive learning environment, without bullies, without unmotivated teachers who's only goal is to "maintain order".
With teachers who have real knowledge about psychology and interest in childrens development, you don't need "discipline" because children are by nature eager to learn.
For comparison: in most countries a teacher has a college degree. In Scandinavia a university education is recommended for a primary school teacher.
