Book Description
Diariamente escuchamos expresiones como "falta un cuarto de hora," "dame la mitad" o "necesito tres cuartos de kilo," entre muchas otras. Esto hace evidente que las fracciones forman parte de nuestra vida cotidiana. Entonces, por que sera tan comun escuchar a los alumnos de diferentes niveles de escolaridad comentar: "yo no les entiendo a las fracciones" o "a mi no me gusta trabajar con fracciones"? Este tipo de comentarios genera toda una serie de interrogantes en relacion a la forma como los profesores entienden los racionales, la manera en la que abordan el tema en su salon de clase y como los alumnos lo perciben. Fundamentalmente, en el trabajo escolar, es necesario sentar bases muy solidas con respecto al concepto de fraccion y sus multiples aplicaciones; al concepto de equivalencia y orden; de flexibilidad del entero. El trabajo cotidiano con una diversidad de materiales concretos permiten al alumno apropiarse de dichos conceptos y construir los cimientos para el posterior desarrollo de los algoritmos de las operaciones con fracciones."

Book Description
The launch ofa new book series is always a challenging eventn ot only for the Editorial Board and the Publisher, but also, and more particularly, for the first author. Both the Editorial Board and the Publisher are delightedt hat the first author in this series isw ell able to meet the challenge. Professor Freudenthal needs no introduction toanyone in the Mathematics Education field and it is particularly fitting that his book should be the first in this new series because it was in 1968 that he, and Reidel, produced the first issue oft he journal Edu cational Studies in Mathematics. Breakingfresh ground is therefore nothing new to Professor Freudenthal and this book illustrates well his pleasure at such a task. To be strictly correct the ‘ground’ which he has broken here is not new, but aswith Mathematics as an Educational Task and Weeding and Sowing, it is rather the novelty oft he manner in which he has carried out his analysis which provides us with so many fresh perspectives. It is our intention that this new book series should provide those who work int he emerging discipline of mathematicseducation with an essential resource, and at a time of considerable concern about the whole mathematics cu rriculum this book represents just such resource.

Book Description
From the bestselling author of the acclaimed Chaos and Genius comes a thoughtful and provocative exploration of the big ideas of the modern era: Information, communication, and information theory. Acclaimed science writer James Gleick presents an eye-opening vision of how our relationship to information has transformed the very nature of human consciousness. A fascinating intellectual journey through the history of communication and information, from the language of Africa’s talking drums to the invention of written alphabets; from the electronic transmission of code to the origins of information theory, into the new information age and the current deluge of news, tweets, images, and blogs. Along the way, Gleick profiles key innovators, including Charles Babbage, Ada Lovelace, Samuel Morse, and Claude Shannon, and reveals how our understanding of information is transforming not only how we look at the world, but how we live.

Book Description
Phosphorus in Environmental Technology: Principles and Applications, provides a definitive and detailed presentation of state-of-the-art knowledge on the environmental behaviour of phosphorus and its applications to the treatment of waters and soils. Special attention is given to phosphorus removal for recovery technologies, a concept that has emerged over the past 5-6 years. The book features an all-encompassing approach: the fundamental science of phosphorus (chemistry, geochemistry, mineralogy, biology), key aspects of its environmental behaviour and mobility, industrial applications (treatment, removal, recovery) and the principles behind such applications, novel biotechnologies and, importantly, it also addresses socio-economic issues which often influence implementation and the ultimate success of any new technology. A detailed subject index helps the reader to find their way through the different scientific and technological aspects covered, making it an invaluable reference work for students, professionals and consultants dealing with phosphorus-related environmental technologies. State-of-the-art knowledge on the behaviour of phosphorus and its applications to environmental science and technology. Covers all aspects of phosphorus in the environment, engineered and biological systems; an interdisciplinary text.

Book Description
A rigorous, pathbreaking analysis demonstrating that a country's prosperity is directly related in the long run to the skills of its population. In this book Eric Hanushek and Ludger Woessmann make a simple, central claim, developed with rigorous theoretical and empirical support: knowledge is the key to a country's development. Of course, every country acknowledges the importance of developing human capital, but Hanushek and Woessmann argue that message has become distorted, with politicians and researchers concentrating not on valued skills but on proxies for them. The common focus is on school attainment, although time in school provides a very misleading picture of how skills enter into development. Hanushek and Woessmann contend that the cognitive skills of the population—which they term the “knowledge capital” of a nation—are essential to long-run prosperity. Hanushek and Woessmann subject their hypotheses about the relationship between cognitive skills (as consistently measured by international student assessments) and economic growth to a series of tests, including alternate specifications, different subsets of countries, and econometric analysis of causal interpretations. They find that their main results are remarkably robust, and equally applicable to developing and developed countries. They demonstrate, for example, that the “Latin American growth puzzle” and the “East Asian miracle” can be explained by these regions' knowledge capital. Turning to the policy implications of their argument, they call for an education system that develops effective accountability, promotes choice and competition, and provides direct rewards for good performance.

Book Description
A manifesto for a radically different philosophy and practice of manufacture and environmentalism "Reduce, reuse, recycle" urge environmentalists; in other words, do more with less in order to minimize damage. But as this provocative, visionary book argues, this approach perpetuates a one-way, "cradle to grave" manufacturing model that dates to the Industrial Revolution and casts off as much as 90 percent of the materials it uses as waste, much of it toxic. Why not challenge the notion that human industry must inevitably damage the natural world? In fact, why not take nature itself as our model? A tree produces thousands of blossoms in order to create another tree, yet we do not consider its abundance wasteful but safe, beautiful, and highly effective; hence, "waste equals food" is the first principle the book sets forth. Products might be designed so that, after their useful life, they provide nourishment for something new-either as "biological nutrients" that safely re-enter the environment or as "technical nutrients" that circulate within closed-loop industrial cycles, without being "downcycled" into low-grade uses (as most "recyclables" now are). Elaborating their principles from experience (re)designing everything from carpeting to corporate campuses, William McDonough and Michael Braungart make an exciting and viable case for change.

Book Description
Based on a four-year study, Manga High explores the convergence of literacy, creativity, social development, and personal identity in one of New York City’s largest high schools. Since 2004, students at Martin Luther King, Jr., High School in Manhattan have been creating manga—Japanese comic books. They write the stories, design the characters, and publish their works in print and on the Internet. These students—African-American and Latino teenagers—are more than interested in the art and medium of manga. They have become completely engrossed in Japanese language, culture, and society. Manga High is highlighted by reproductions and content analysis of students’ original art and writing. An appendix includes guidelines for educators on starting a comic book club.
