Book excerpt: Invisible Learning reveals the secrets behind one of Harvard's most successful statistics courses. Dan Levy is famous at Harvard for his inclusive learning environment, which leaves students feeling not just confident about using statistics in the real world, but also seen, heard and loved. Written from the perspective of the student, the book is a fly-on-the-wall case study of the course. It argues that the learning environment is composed of invisible bonds between students and teacher, and considers how he strengthens those bonds and uses them to maximise learning. It seeks to answer the question, asked by students and Harvard faculty alike: "How does he do it?"
