In Elkhorn Slough, an inlet on the California coast, seagrass grows healthy and strong in the shallow water. This healthy seagrass baffled marine biologist Brent Hughes. The scientist expected this estuary to be overrun with algae, causing the seagrass to die. Why was the seagrass thriving? As Brent investigated, signs pointed to an unexpected player helping to keep the seagrass healthy: sea otters! What do these top predators have to do with an aquatic grass at the opposite end of the food chain? Brent's discovery gave scientists insight into the delicate balance of ecosystems. Follow science in action as Brent conducts the research that led to this major discovery.

    We call this imprisonment schooling, yet wonder why kids become bored and misbehave. Even outside of school children today seldom play and explore without adult supervision, and are afforded few opportunities to control their own lives. The result: anxious, unfocused children who see schooling—and life—as a series of hoops to struggle through.In Free to Learn, developmental psychologist Peter Gray argues that our children, if free to pursue their own interests through play, will not only learn all they need to know, but will do so with energy and passion. Children come into this world burning to learn, equipped with the curiosity, playfulness, and sociability to direct their own education. Yet we have squelched such instincts in a school model originally developed to indoctrinate, not to promote intellectual growth.To foster children who will thrive in today’s constantly changing world, we must entrust them to steer their own learning and development. Drawing on evidence from anthropology, psychology, and history, Gray demonstrates that free play is the primary means by which children learn to control their lives, solve problems, get along with peers, and become emotionally resilient. This capacity to learn through play evolved long ago, in hunter-gatherer bands where children acquired the skills of the culture through their own initiatives. And these instincts still operate remarkably well today, as studies at alternative, democratically administered schools show. When children are in charge of their own education, they learn better—and at lower cost than the traditional model of coercive schooling.A brave, counterintuitive proposal for freeing our children from the shackles of the curiosity-killing institution we call school, Free to Learn suggests that it’s time to stop asking what’s wrong with our children, and start asking what’s wrong with the system. It shows how we can act—both as parents and as members of society—to improve children’s lives and promote their happiness and learning.

    Ellen J. Langer and her team of researchers at Harvard introduced a unique concept of mindfulness, adapted to contemporary life in the West. Langer's theory has been applied to a wide number of fields, including health, business, aging, social justice, and learning. There is now a new psychological assessment based on her work (called the Langer Mindfulness Scale).
