Download or read book The Myth of Achievement Tests written by James J. Heckman and published by University of Chicago Press. This book was released on 2014-01-14 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: Achievement tests play an important role in modern societies. They are used to evaluate schools, to assign students to tracks within schools, and to identify weaknesses in student knowledge. The GED is an achievement test used to grant the status of high school graduate to anyone who passes it. GED recipients currently account for 12 percent of all high school credentials issued each year in the United States. But do achievement tests predict success in life? The Myth of Achievement Tests shows that achievement tests like the GED fail to measure important life skills. James J. Heckman, John Eric Humphries, Tim Kautz, and a group of scholars offer an in-depth exploration of how the GED came to be used throughout the United States and why our reliance on it is dangerous. Drawing on decades of research, the authors show that, while GED recipients score as well on achievement tests as high school graduates who do not enroll in college, high school graduates vastly outperform GED recipients in terms of their earnings, employment opportunities, educational attainment, and health. The authors show that the differences in success between GED recipients and high school graduates are driven by character skills. Achievement tests like the GED do not adequately capture character skills like conscientiousness, perseverance, sociability, and curiosity. These skills are important in predicting a variety of life outcomes. They can be measured, and they can be taught. Using the GED as a case study, the authors explore what achievement tests miss and show the dangers of an educational system based on them. They call for a return to an emphasis on character in our schools, our systems of accountability, and our national dialogue.

Download or read book Environmentally Significant Consumption written by National Research Council and published by National Academies Press. This book was released on 1997-07-09 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been much polemic about affluence, consumption, and the global environment. For some observers, "consumption" is at the root of global environmental threats: wealthy individuals and societies use far too much of the earth's resource base and should scale back their appetites to preserve the environment for future generations and allow a decent life for the rest of the world. Other observers see affluence as the way to escape environmental threats: economic development increases public pressure for environmental protection and makes capital available for environmentally benign technologies. The arguments are fed by conflicting beliefs, values, hopes, and fearsâ€"but surprisingly little scientific analysis. This book demonstrates that the relationship of consumption to the environment needs careful analysis by environmental and social scientists and conveys some of the excitement of treating the issue scientifically. It poses the key empirical questions: Which kinds of consumption are environmentally significant? Which actors are responsible for that consumption? What forces cause or explain environmentally significant consumption? How can it be changed? The book presents studies that open up important issues for empirical study: Are there any signs of saturation in the demand for travel in wealthy countries? What is the relationship between environmental consumption and human well-being? To what extent do people in developing countries emulate American consumption styles? The book also suggests broad strategies that scientists and research sponsors can use to better inform future debates about the environment, development, and consumption.

Download or read book The Art Science of Learning Design written by Marcelo Maina and published by Springer. This book was released on 2015-07-21 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live in an era defined by a wealth of open and readily available information, and the accelerated evolution of social, mobile and creative technologies. The provision of knowledge, once a primary role of educators, is now devolved to an immense web of free and readily accessible sources. Consequently, educators need to redefine their role not just “from sage on the stage to guide on the side” but, as more and more voices insist, as “designers for learning”. The call for such a repositioning of educators is heard from leaders in the field of technology-enhanced learning (TEL) and resonates well with the growing culture of design-based research in Education. However, it is still struggling to find a foothold in educational practice. We contend that the root causes of this discrepancy are the lack of articulation of design practices and methods, along with a shortage of tools and representations to support such practices, a lack of a culture of teacher-as-designer among practitioners, and insufficient theoretical development. The Art and Science of Learning Design (ASLD) explores the frameworks, methods, and tools available for teachers, technologists and researchers interested in designing for learning Learning Design theories arising from findings of research are explored, drawing upon research and practitioner experiences. It then surveys current trends in the practices, methods, and methodologies of Learning Design. Highlighting the translation of theory into practice, this book showcases some of the latest tools that support the learning design process itself.

Download or read book Rubric Nation written by Michelle Tenam-Zemach and published by IAP. This book was released on 2015-04-01 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is a rubric and how are they being used in teacher education and evaluation? When did rubrics become ubiquitous in the field of education? What impact do rubrics have on students, teachers, teacher educators, and the educational enterprise? This book is an edited volume of essays that critically examine the phenomenon of rubrics in teacher education, evaluation and education more broadly. Rubrics have seen a dramatic rise in use and presence over the past twenty-five years in colleges of education and districts across the country. Although there is a wealth of literature about how to make rubrics, there is scant literature that explores the strengths and weaknesses of rubrics and the impact the rubric phenomenon is having in reshaping education. The chapters included in this edited volume will critically reflect on the contemporary contexts of rubrics and the uses and impact of rubrics in education. Since rubrics have become indelible in education, it is necessary for a fuller, nuanced discussion of the phenomenon. Creating a book that explores these aspects of rubrics is timely and fundamental to expanding the discourse on this ubiquitous evaluation tool. This book is not meant to be a series of chapters dedicated to best practices for creating rubrics, nor is this text meant to present all sides of the rubric discussion. Rather, this text intends to offer critical polemics about rubrics that can spur greater critical discussion about a phenomenon in education that has largely been unquestioned in the literature.
