Resumen de Make It Stick

In Make It Stick, cognitive scientists Peter C. Brown, Henry L. Roediger III, and Mark A. McDaniel argue that the most common study habits—rereading, highlighting, and massed practice—are largely ineffective because they produce fluency that feels like learning but fades quickly. Drawing on decades of experimental psychology, the book shows that durable learning comes instead from retrieval practice, spacing, and interleaving: quizzing yourself rather than reviewing, distributing practice over time, and mixing related topics or problem types instead of drilling one at a time. The authors explain why these methods feel harder and slower even as they produce stronger retention, a phenomenon they call a desirable difficulty. Specific studies anchor the argument, including Roediger and Karpicke's research on testing versus restudying prose passages, and experiments with interleaved versus blocked mathematics practice in classrooms. The book also addresses illusions of knowing, the limits of learning styles, and the value of elaboration, generation, and reflection. Later chapters extend these principles to lifelong learning, showing how retrieval and spacing apply to medical training, surgery, and professional expertise, and it discusses calibration—learning to judge accurately what you actually know. The 2014 Harvard University Press book grew from a collaboration among Brown, a novelist and writer, and Washington University in St. Louis psychologists Roediger and McDaniel, whose research on memory and testing effects underpins it. Each chapter pairs a principle with concrete examples and ends with takeaway tips for students, teachers, and trainers, making the case that effective learning is an active, effortful, and test-driven process rather than passive exposure.
