This infographic was shared with me to shed light on why a system, like Common Core, was needed for American students. I thought it well done and it does shed light on why change is needed.
Now, whether or not all of the Common Core parts are sanely written and administrated is another debate.
But, I think you can see from these statistics, that an overall change was required.
I am not saying Common Core (the way it is organized, written and was implemented) is the answer; I am saying a CHANGE is and was required.
Further reasonable discussion, debate and awareness has the potential of bringing about a much better scene overall if we work from the premise a change needed to occur in our public education system.
