Feedback is one of the most important words when I began to learn automatic control theory in college. The PID algorithm is such a beauty to do object tracking automatically in our real life which has been advancing human life for many many years. One application is the cruise control button in our car. As simple as when we drive on the highway, we will slow down when we are too fast, we need accelerate when are too slow. Human has the built-in feedback system which is learned over years when we grow up.
Our school system needs such a feedback mechanism too. A consistent, timely feedback mechanism should be built into our school program performance evaluation. In software design, we have another term: continuous integration and testing. That means the system will automatically check the system performance without any human interference when there is any change . This will minimize human errors. We also need the feedback mechanism to run continuously and share that result with us whenever available. Any anomaly in the system will be detected automatically and then analyzed by humans later.
Many our school programs are multi-layered. However, we should try our best to set some quantifiable, measurable objective function, evaluate them continuously and get the feedback into the human hands periodically.
We should make substantial effort to get the input data right, set up a feedback process and evaluate program performance continuously for our school system.
