I watched the film and don't recall that many Finnish comparisons. The cultures here and there are also probably vastly different, when it comes to unions.
The film tackles several topics, such as unions, teacher performance, and charter schools, created using public money, but free from union contracts.
It's a pretty compelling case, seeing the %'s of students that end up going to college from charter schools vs normal public education.
It's not a bad argument here to say throwing more money at the systems isn't going fix the problem. As a nation, we need to address simple things like tenure and teacher unions, force parents to become more aware, and making teaching more appealing.
it's funny how the D.C chancellor introduced an option for teachers to give up tenure for a chance at higher salaries via merit based pay, but the unions saw it as so threatening to their culture, that they defeated this option from even becoming available to teachers.
it shouldn't be so hard to fire the bad teachers and replace them with a different teacher. At least make it simple to get rid of them during the summer, tenure be damned.
