I recently read an editorial piece by Arlene Ackerman, former Philadelphia public schools superintendent and longtime educator, on how she came to the realization that our public education system will not improve on its own. I have come to the same realization, because among other reasons, there is no indication school districts are suddenly going to hold themselves accountable for elevating the academic achievement of all students; or take every step necessary to ensure all students only have effective teachers. There are also just too many people who have a vested interest in keeping the current system intact, who are resistant to even the smallest of changes – let alone the dramatic improvements most of us recognize must be made in order for the system to succeed.
The traditional school establishment and its supporters know if you change the ingredients, it likely changes the recipe. If you change the recipe, you get a different dish; and, there are no real internal motivators to change a system that has served a whole bunch of adults so well for such a long time.
