In the US, the decades of weak pay, support and heavy criticism almost seem like a high point compared to the demonization of more recent years.
It seems to me that those that become teachers in Finland have chosen the career fairly early on. It's a vocational thing. Money doesn't influence the decision, but of course there is the financial baseline that teaching is a stable job that offers an extraordinarily long summer vacation (something like 11 weeks, fully paid).
Wow -- that alone could cause a number of the effects we're talking about. Anyone who wants to go to college can, versus in the US, there are a number of children who know (or pessimistically assume) that college is just not in the cards for them.
Not saying we should adopt that single tenet. Just that it has surprisingly strong ripples throughout the whole system that should not be underestimated.
That's partially because many parents see school as free childcare and don't understand the value of education themselves. This in turn is because parents are (in general) spending more time away from their children trying to "make ends meet" which itself has to do with consumer culture and living beyond means. It's a complex problem.
The 2nd interesting point I took away is the ability grouping. Not grouping by ability works for young children, say K-6. But once older, the gap is too much for a unified curriculum. Taking this concept further out, Americans need more vocational high schools, like Finland. College is overvalued in this country, and a large segment of high school students are being misled by the college myth.
Why do you think bad teachers would work their way out of the system due to competition? Ontario pays teachers generously and as a result has a glut of teachers (widespread unemployment amongst new teachers, people going abroad, certainly many of these people would be good teachers). There's no "competition" because the challenge is to get on the supply list, and then get hired into the unionized workplace. Once you're there, don't worry about getting fired. The main struggle is getting in, not avoiding getting out. High pay does necessarily lead to the sort of competition that I think you have in mind.
Not to go pop commentary on you, but Malcom Gladwell once wrote a piece on this very thing. <http://www.newyorker.com/reporting/2008/12/15/081215fa_fact_...;
