Education isn't failing. Teachers are side-tracked, kids are side-tracked, and too many people have their attention focused on what their selected media site is telling them but in reality the world is actually a much better place than the screen would sometimes tell us. Like Luke Bryan says, "most people are good".
I think if you listen to the noise you will believe it. But in reality, look around you and see what's really going on. Not outside your walls but inside. And then plow ahead because truth be told, most people ARE good and most kids ARE learning regardless of the noise. One day at a time and control your four walls and the rest of it let go. My child has some classes that are learning because the teacher doesn't make excuses. They teach. Other classes not so much because the teachers spend more time making excuses or not teaching because they have given up. Be the teacher that just teachers. That's what the kids really want.
