As a Techie, this was the biggest eye opener for me when I worked on EdTech: At average, a teacher spends 20% time outside of school hours preparing for their class. Its crazy!
Plus, add in the stress of being in the classroom in today's political climate, where teachers can be sued from left and from right and we have got a real problem.
To fix teaching in America, we need to radically transform the education system and stop playing politics. Or else, we are going to lose a whole lot of talented teachers and our country is already going down a slippery slope.
