Book Description
Dark Matter, Dark Energy and Dark Gravity make life possible!This book for the lay reader provides a summary of the latest astrophysical observational results and theoretical insights into what we know and what we hope to learn about dark matter, dark energy, and dark gravity.How did the profound beauty of our Earth, our Solar System, our Milky Way galaxy and indeed our universe unfold? Dark matter, dark energy, and dark gravity have made all the difference in how the universe has developed, and have been key to creating the overall environment that makes life possible. We have only recently developed the ability to begin unlocking their secrets, thus providing a deeper insight into how a universe of our type is possible. It seems that because of dark matter, dark energy and dark (weak) gravity, our universe has the right attributes for the development of complex structure and the evolution of intelligent life that can engage in the quest to understand our world. These "dark" or more hidden attributes of the cosmos have very good outcomes.In particular, the existence of dark matter makes it easier to form complex structures, including galaxies, stars and planets through gravitational collapse of denser regions of the universe. Planets are the most suitable abodes for the development of life. Dark energy acts to extend the lifetime of the universe by counteracting gravity and driving continued expansion of the universe.Even as far back as the 1930s there has been evidence that most of the matter in the universe was not visible via electromagnetic radiation (optical light, radio waves, etc.). By the last few decades of the 20th century, the case for a considerable amount of this dark matter was very strong. It is the second largest contributor to the total mass-energy of the universe. We don't know what it is and there are various candidates to explain it; nevertheless we see the gravitational effects of dark matter everywhere on the largest scales. Recent observational results indicate that dark matter dominates by a factor of 6 relative to the ordinary matter that makes up stars, planets, and living things.We now know that the major contributor to the mass-energy of the universe is not the substantial dark matter, but the 'newer' so-called dark energy. Dark energy acts to some extent as a negative gravity, and for the last several billion years has driven the expansion of the universe to a faster and faster pace, overcoming even the gravitational effect of dark matter. We have a general idea that it is the irreducible energy found in every volume of space, even in the absence of matter - in the vacuum. We don't understand why it takes the value that it does, one that is small in quantum particle physics terms, but nevertheless is of great significance on the large cosmological scale of the universe. The third important aspect to consider is not a mass-energy component, but the nature of gravity and space-time. The big question here is - why is gravity so relatively weak, as compared to the other 3 forces of nature? These 3 forces are the electromagnetic force, the strong nuclear force, and the weak nuclear force. Gravity is different - it has a dark or hidden side. It may very well operate in extra dimensions beyond the normal 4 dimensions of space-time that we can observe. This is what we mean in this book by "dark gravity".

Book Description
Note: A newer edition of this title is available. The framework for teaching is a research-based set of components of instruction that are grounded in a constructivist view of learning and teaching. The framework may be used for many purposes, but its full value is realized as the foundation for professional conversations among practitioners as they seek to enhance their skill in the complex task of teaching. The framework may be used as the foundation of a school's or district's recruitment and hiring, mentoring, coaching, professional development, and teacher evaluation processes, thus linking all those activities together and helping teachers become more thoughtful practitioners. The actions teachers can take to improve student learning are clearly identified and fall under four domains of teaching responsibility: Planning and Preparation, the School Environment, Instruction, and Professional Responsibilities. Within the domains are 22 components and 76 descriptive elements that further refine our understanding of what teaching is all about. The framework defines four levels of performance (Unsatisfactory, Basic, Proficient, and Distinguished) for each element, providing a valuable tool that all teachers can use. This second edition has been revised and updated and also includes frameworks for school specialists, such as school nurses, counselors, library and media specialists, and instructional coaches. Comprehensive, clear, and applicable to teaching across the K-12 spectrum, the framework for teaching described in this book is based on the PRAXIS III: Classroom Performance Assessment criteria developed by Educational Testing Service and is compatible with INTASC standards.

Book Description
As seen in ESPN Films’ Unguarded, a “powerful . . . bracing . . . exceptional” true account of the former NBA and overseas pro’s rise and harrowing fall (NPR Books). I was dead for thirty seconds. That’s what the cop in Fall River told me. When the EMTs found me, there was a needle in my arm and a packet of heroin in the front seat. At basketball-crazy Durfee High School in Fall River, Massachusetts, junior guard Chris Herren carried his family’s and the declining city’s dreams on his skinny frame. He was heavily recruited by major universities, chosen as a McDonald’s All-American, featured in a Sports Illustrated cover story, and at just seventeen years old became the central figure in Fall River Dreams, an acclaimed book about the 1994 Durfee team’s quest for the state championship. Leaving Fall River for college, Herren starred on Jerry Tarkanian’s Fresno State Bulldogs team of talented misfits, which included future NBA players as well as future convicted felons. His gritty, tattooed, hip-hop persona drew the ire of rival fans and more national attention: Rolling Stone profiled him, 60 Minutes interviewed him, and the Denver Nuggets drafted him. When the Boston Celtics acquired his contract, he lived the dream of every Massachusetts kid—but off the court Herren was secretly crumbling, as his alcohol and drug use escalated and his life spiraled out of control. Twenty years later, Chris Herren was a husband, a father, and a heroin junkie, who would flirt with death—and ultimately live to tell about it.

Book Description
Teacher evaluation is arguably the hottest issue in education right now. Because of Race to the Top, many states and districts around the country are designing and implementing new teacher evaluation systems that--for the first time ever--evaluate teachers based on how much their students learn. However, there is limited research on how to build an evaluation system centered on classroom observations that can distinguish between effective and ineffective teaching. This report from the University of Chicago Consortium on School Research focuses on Chicago, but the lessons learned have significant applicability to districts across the country. The report is one of the first to provide research-based evidence showing that new teacher observation tools, when accompanied by thoughtful evaluation systems and professional development, can effectively measure teacher effectiveness and provide teachers with feedback on the factors that matter for improving student learning. This is especially relevant for those districts that are implementing the Charlotte Danielson Framework for Teaching, including Arkansas, Delaware, Florida, Idaho, Illinois, New Jersey, New York, South Dakota, Washington, Los Angeles, and Pittsburgh.

Book Description
NATIONAL BESTSELLER A unique, unfiltered memoir from the NBA champion and fifteen-time all-star ahead of his induction into the Hall of Fame. Kevin Garnett was one of the most dominant players the game of basketball has ever seen. He was also one of its most outspoken. Over the course of his illustrious twenty-one-year NBA career, he elevated trash talk to an art form and never shied away from sharing his thoughts on controversial subjects. In KG A to Z, published ahead of Garnett’s induction into the Basketball Hall of Fame, he looks back on his life and career with the same raw candor. Garnett describes the adversity he faced growing up in South Carolina before ultimately relocating to Chicago, where he became one of the top prospects in the nation. He details his headline-making decision to skip college and become the first player in two decades to enter the draft directly from high school, starting a trend that would be followed by future superstars like Kobe Bryant and LeBron James. He shares stories of playing with and against Bryant, James, Michael Jordan, and other NBA greats, and he chronicles his professional ups and downs, including winning a championship with the Boston Celtics. He also speaks his mind on a range of topics beyond basketball, such as fame, family, racism, spirituality, and music. Garnett’s draft decision wasn’t the only way he’d forever change the game. His ability to play on the perimeter as a big man foreshadowed the winning strategy now universally adopted by the league. He applies this same innovative spirit here, organizing the contents alphabetically as an encyclopedia. If you thought Kevin Garnett was exciting, inspiring, and unfiltered on the court, just wait until you read what he has to say in these pages.
