In this article, Eric Schwarz describes how "Citizen Schools" are coming to the aid of teachers by adding a second shift of educators that make teachers more effective and happier, while also improving the outcomes of its students. Teaching fellows and volunteer citizen teachers could support the master and core teachers while also extending the learning day, providing more time for academic practice, more time for personalized learning, and significantly more time for students to make and do things with real professionals. Adding a second shift of educators in schools could fundamentally change the teacher's job for the better, making it more sustainable and enjoyable while bringing more resources to kids and engaging families more deeply in their child's education.
