Finland's success in Pisa scores is the reason that these practices are highlighted. Although homogenous population plays a role, Finnish scores are constantly better than almost equally homogenous Norway. However, the true reason behind the success of Finnish school system is yet unclear. One thing that certainly plays an important role is that teacher as a profession has traditionally been highly regarded in Finnish society, and it's not trivial to get in to universities to study teaching. There are other interesting aspects, for example does the language play a role: Finland has an affluent Swedish-speaking minority. There a separate schools for Swedish speakers, but they follow similar practices as the rest of the Finnish schooling system. However, for some odd reason doesn't fare as well in Pisa tests than Finnish speaking students, despite that family background of Swedish speakers have traditionally been more stable.
