As is the case in the earth system, educational subsystems are interactive. What affects one system will affect another, maybe not today or tomorrow, but in the long term. The common thread that ties all the systems together, whether it be the earth or education, is the exchange of energy and mass. In the case of the educational system, the energy and mass exchanged is students moving from one grade to the next, or from teacher preparation programs into the pre-college classroom. One system feeds on the other.
Systems are dynamic, and the only thing that is constant is change.
The type of change is a function of the feedback mechanisms between the individual parts. Feedback can be either positive or negative. We will be happy to help you. The list is current as of February 1, 1998. For those that did not, your membership information may no longer be accurate.
