Education is a very important part of any good society and a good equational system makes for a better world. In Finland, they have found a way to have a relaxing, effective, and the world’s best educational environment. The BBC has an article with some videos (which I can’t embed here) on the awesomeness of Finnish schools.
The Finnish philosophy with education is that everyone has something to contribute and those who struggle in certain subjects should not be left behind.
A tactic used in virtually every lesson is the provision of an additional teacher who helps those who struggle in a particular subject. But the pupils are all kept in the same classroom, regardless of their ability in that particular subject.
