Few if any people, including boards of education, may realize teacher frustrations. The result is partly from ignored limitations imposed on teachers. Resulting gaps develop between what teachers feel they want and might achieve and pressure limiting their expectations. School may seem good for those who succeed. It could be much better for more people if there could be more discussion and dialogue at every level among educators, rather than debate and the silence resulting from coercion.
Consequences spill out where teachers and students meet.
It isn't enough to identify symptoms. We need to understand causes, not simply to know about them. The same discussion and dialogue is needed between urban and suburban schools, between schools and the public everywhere. All face similar challenges. Verbal commitments to understand are worthless if every criticism of education is met with a wall of protective voices.
