Put an archived web cam in every public school classroom, and all the problems would disappear. Incompetent and political teachers would be driven out rapidly.
You would think so. We thought by putting camera on school busses, that behavior would improve—but you can’t show the little terror’s parents his misbehavior unless you blur out all of the other children’s faces. Without video proof (and sometimes even with it!) parents can and will deny anything ever happened.
Yes there are incompetent/political teachers out there, but believe it or not, they are not what is killing public education. It is a combination of a major societal breakdown of a significant proportion of the schools’ population combined with an attitude that the bell-shaped curve applies to everything in nature except scholastic aptitude.
