Why is the Finnish schools better than the Danish and Swedish ones?

Today when we were at Kaakkuri school we were discussing the school systems of the different countries (Sweden, Finland and Denmark. We tried to see if there was differences in the family patterns, but no, all three countries are dealing with families with different formations. Maybe we could see that the Finnisch families still relied a lot to school because of II WW, that has had a greater impact here in Finladn because of the great destruction of the country under the war. Education therefore was very important and still is. One of the things that strike me is that they seem to work more systematically than we do. So it´s not the content but the systematic in how you work and follow it up that differs.
Another thing is that the work that has to do with other things except teaching, like team work, is not a great part of a Finnish teachers job. When you teach higher grades, from 7th you mostly teach just one subject, could this have an impact?

One other thing we talked about was how many students that went on to upper secondary (gymnasiet)and how to encourage it. We really did not find any solution there. I mentioned that we have an interest in looking into, maybe in a Comenius Regio Project, how to help the students and the teachers to overcome the sometimes big step from lower Secondary to Upper Secondary School. Maybe we could build a project from this with Denmark and Finland.
