> "The issue boils down to the pervasiveness of bad teachers in the system, and an inability to get rid of those teachers and reward/promote good teachers."
As others have mentioned, that is seen as a solution (and one that the US is acting on), however MANY disagree heavily that that is the core issue, as do I. I hope no one is offended by this comparison, but I believe it can be compared to the issue with the massive amount of people in prison in US problem -- can there really be that many bad people, or is the issue something else? I'm 100% convinced it's something else, specifically that (in a lot of cases) the system itself causes the behaviors by motivating/incentivizing it.
I agree with you that "bad teachers" is not the core or only issue. A more serious issue, as an example, is that good teachers are actively driven away by petty bureaucrats. Those that remain are severely constrained in the good they can do. With the advent of endemic standardized testing tied into bonuses and tenure, classes have devolved into regurgitate the answer mode. That issue, of really excellent teaching being punished or prohibited, is only one of many many problems in the system. Easy fixes don't work because there is not just one thing that is the problem. There are many things and the things vary somewhat state by state and district by district within a state.
