Jaime Escalante didn't just teach calculus in East LA; he blew up the lie that poor, minority students can't handle serious academics-and then watched the system quietly bury the evidence. Defying Low Expectations tells the story beyond Stand and Deliver, the 1988 film about Escalante starring Edward James Olmos that became a classroom staple. Here we learn about the immigrant teacher from Bolivia, the maverick principal Henry Gradillas who cleared a path for him, and the forces that dismantled their success once it became too threatening to the status quo. Drawing on fresh interviews, lost online material, and hard data about today's failing schools, Dembski and Thomas show how Escalante created an ecosystem where students did the hard thing-and won big. This isn't nostalgia. It's a blueprint for rescuing American education. Escalante's example exposes low expectations as educational malpractice and shows how disciplined teaching, principled leadership, and moral courage can turn "throwaway" American schools into powerhouses of learning.
