This week on Uncommon Knowledge, Joel Klein, Amplify CEO and former chancellor of the New York City department of education, discusses technology, school choice, and the challenges facing the US educational system. The gap between the haves and the have-nots is growing, with huge implications for the United States; the way to reduce the gap and create knowledgeable, skilled, problem solvers is through education. For the past two hundred years we have had the model of one teacher and thirty plus children, but that model is not working for many students. With less than one-third of students ready for college, Amplify is reimagining the way teachers teach and students learn to build a better Kó12 educational system and thus a better society.
