The quality & morale of teachers is absolutely central to the well being of students and their learning.
In Finland, within very broad government guidelines, teachers create their own curricula together across schools in every community and district. They don't confine collaboration to their own individual schools and to just implementing other people's ideas.
Professional trust is a process, not a state.
There is no morality without temptation; otherwise it is just lack of opportunity.
Trust processes as well as people.
We need standards with flexibility, not standardization with force if we are to get the best from our teachers.
