I also think that it helps to be very direct (depending on the teacher and how open they seem to parent input) and say that you have some ideas about how things could work but you want to work with her as a team and brainstorm solutions, come up with a plan for how to proceed, and that she should feel free to experiment. I think it's actually easier to bring up concerns earlier in the school year so the teacher doesn't take it personally, or as criticism. Of course this is exactly the approach I took last year and it didn't go well. The teacher simply did not get it. I think in those cases a school or teacher change is in order (if possible) rather than trying to fight it.
