Yet we still don't know what, precisely, makes a teacher great. Is it a matter of natural-born charisma? Or does exceptional teaching require something more? Building a Better Teacher introduces a new generation of educators exploring the intricate science underlying their art. A former principal studies the country s star teachers and discovers a set of common techniques that help children pay attention. Two math teachers videotape a year of lessons and develop an approach that has nine-year-olds writing sophisticated mathematical proofs. A former high school teacher works with a top English instructor to pinpoint the key interactions a teacher must foster to initiate a rich classroom discussion. Through their stories, and the hilarious and heartbreaking theater that unfolds in the classroom every day, Elizabeth Green takes us on a journey into the heart of a profession that impacts every child in America.What happens in the classroom of a great teacher? Opening with a moment-by-moment portrait of an everyday math lesson a drama of urgent decisions and artful maneuvers Building a Better Teacher demonstrates the unexpected complexity of teaching. Green focuses on the questions that really matter: How do we prepare teachers and what should they know before they enter the classroom? How does one get young minds to reason, conjecture, prove, and understand? What are the keys to good discipline? Incorporating new research from cognitive psychologists and education specialists as well as intrepid classroom entrepreneurs, Green provides a new way for parents to judge what their children need in the classroom and considers how to scale good ideas. Ultimately, Green discovers that good teaching is a skill. A skill that can be taught.A provocative and hopeful book, Building a Better Teacher shows that legendary teachers are more than inspiring; they are perhaps the greatest craftspeople of all."

    In this book, Fred Krupp, longtime president of Environmental Defense Fund, brings a stirring and hopeful call to arms: We can solve global warming. And in doing so we will build the new industries, jobs, and fortunes of the twenty-first century.In these pages the reader will encounter the bold innovators and investors who are reinventing energy and the ways we use it. Among them: a frontier impresario who keeps his ice hotel frozen all summer long with the energy of hot springs; a utility engineer who feeds smokestack gases from coal-fired plants to voracious algae, then turns them into fuel; and a tribe of Native Americans, for two thousand years fishermen in the roughest Pacific waters, who are now harvesting the fierce power of the waves themselves.These entrepreneurs are poised to remake the world's biggest business and save the planet—if America's political leaders give them a fair chance to compete.

    Fuller expresses what may well be his penultimate view of the human condition. Here, in a mood at once philosophical and involved, Mr. Fuller traces man's intellectual evolution and weighs his capability for survival on this magnificent craft, this Spaceship Earth, this superbly designed sphere of almost negligible dimension in the great vastness of space.Mr. Fuller is optimistic that man will survive and, through research and development and increased industrialization, generate wealth so rapidly that he can do very great things. But, he notes, there must be an enormous educational task successfully accomplished right now to convert man's tendency toward oblivion into a realization of his potential, to a universe-exploring advantage from this Spaceship Earth.It has been noted that Mr. Fuller spins ideas in clusters, and clusters of his ideas generate still other clusters. The concept spaceship earth is Mr. Fuller's, and though used by Barbara Ward as the title of a work of her own the idea was acknowledged by her there as deriving from Mr. Fuller. The brilliant syntheses of some fundamental Fuller principles given here makes of this book a microcosm of the Fuller system.

    In How to Clone a Mammoth, Beth Shapiro, evolutionary biologist and pioneer in "ancient DNA" research, walks readers through the astonishing and controversial process of de-extinction. From deciding which species should be restored, to sequencing their genomes, to anticipating how revived populations might be overseen in the wild, Shapiro vividly explores the extraordinary cutting-edge science that is being used--today--to resurrect the past. Journeying to far-flung Siberian locales in search of ice age bones and delving into her own research--as well as those of fellow experts such as Svante Paabo, George Church, and Craig Venter--Shapiro considers de-extinction's practical benefits and ethical challenges. Would de-extinction change the way we live? Is this really cloning? What are the costs and risks? And what is the ultimate goal?Using DNA collected from remains as a genetic blueprint, scientists aim to engineer extinct traits--traits that evolved by natural selection over thousands of years--into living organisms. But rather than viewing de-extinction as a way to restore one particular species, Shapiro argues that the overarching goal should be the revitalization and stabilization of contemporary ecosystems. For example, elephants with genes modified to express mammoth traits could expand into the Arctic, re-establishing lost productivity to the tundra ecosystem.Looking at the very real and compelling science behind an idea once seen as science fiction, How to Clone a Mammoth demonstrates how de-extinction will redefine conservation's future.
