"Work Hard. Be Nice." is an inspiring journey through the transformative power of education, chronicled with heart and insight by Jay Mathews. It traces the formidable path of Mike Feinberg and Dave Levin, two young teachers who emerged from their initial classroom failures with a relentless commitment to become the educators they had once dreamed of being. Their story is not just one of personal triumph but of a revolutionary educational movement. The creation of the Knowledge Is Power Program (KIPP) stands as a testament to their vision, transforming the lives of thousands of students across the United States with schools that stretch from coast to coast. Mathews masterfully captures the essence of KIPP, where the mantra "Work hard, be nice" is more than just a slogan—it's a way of life. Through vivid narratives, the book delves into the innovative teaching strategies and the unwavering belief in the potential of every student that defines the KIPP ethos. The longer school days, the constant availability of teachers, and the incorporation of chants and songs are not mere details but pivotal elements of a groundbreaking educational model. This is a book that goes beyond the story of two men's quest to redefine teaching. It's a hopeful, compelling look at what it means to challenge the status quo and make a genuine difference in the world of education.
