I think the model in Finland is better because it rewards talented teachers. Those teachers, if you have a favorite one, would excel at devising ways to simplify complicated things, I think.
Finland doesn't have the obscenity that is homeless kids coming to school tired because they couldn't sleep, hungry, scared because of violence and instability in their life circumstances, and otherwise with so many strikes against them it would take a miracle for them just to graduate, let alone thrive.
