Finland is a really interesting model. One of the big reasons for their PISA success was the way they were able to improve the performance of the lower ability pupils.
The biggest reform they made in the 70s-80s was to enforce mixed-ability teaching for the first 9 years of schooling (up to age 16). But at the same time the teaching style was fairly universally very traditional, and continued to be so until fairly recently (and possibly still is today). This is something that is hardly ever mentioned in articles about Finnish education, yet it seems to me to quite important, given what we know about how lower-ability pupils are more likely to struggle with constructivist methods.
I suspect if we wanted to emulate Finnish education, we would also need to emulate their teaching methods, but the beliefs among influential educationalists in this country, including much of ITT, appear to run directly counter to that.

Interestingly, I have found three other links in the past to blogs and reports produced by progressive visitors, which deplore the lack of progressive practices they have observed in visits to Finnish schools, but these have unfortunately ended up deleted by their authors.
