“Through this wonderful book, frustrated golfers can learn to swing like Moe [Norman] and improve their games.” —Anthony Robbins, #1 New York Times–bestselling author The mysterious and reclusive genius Moe Norman is acknowledged as the best ball-striker in the history of golf by many of the game’s greats. The Single Plane Golf Swing: Play Better Golf the Moe Norman Way reveals the secrets of the swing that enabled him to hit the ball solidly with unerring accuracy and consistency—every time. Norman’s simple, efficient, and easily understood Single Plane Swing has improved the games of thousands of golfers. Golf professional Todd Graves, known as “Little Moe” and regarded as the world authority on Norman’s swing, comprehensively teaches readers the mechanics, drills, and feelings of the Single Plane Swing that Moe called “The Feeling of Greatness.” Graves shares Norman’s brilliant insights and liberating approach to the game and demonstrates why the conventional “tour” swing is too complex and frustrating for the majority of amateurs. Illustrated with more than 300 photographs and written with Tim O’Connor, Norman’s biographer, the book also engagingly tells Norman’s bittersweet life story and explores the teacher-student bond forged between Norman and his protégé Graves. “One of golf’s greatest untold stories, Moe Norman’s life illustrated a simple and powerful truth: greatness is built from practicing the right swing in the right way. In this book, Todd Graves has given us a blueprint for that swing, for those practice habits, and most of all for a process that builds success.” —Dan Coyle, New York Times-bestselling author of The Culture Code

An invigorating examination of the potential for meaningful change in education, from one of the nation's most astute observers of schooling and school improvement. In The Great School Rethink, education policy sentinel Frederick M. Hess offers a pithy and perceptive appraisal of American schooling and finds, in the uncertain period following pandemic disruption, an ideal moment to reimagine US education. Now is the time, he asserts, to ask hard questions about how schools use time and talent, how they work with parents, what they do with digital tools, and how they meet the needs of their communities. As Hess explains, to rethink is to acknowledge the realities of the education system while opening one’s mind to possibility. With characteristic verve and wit, Hess guides readers through his rethink process, a versatile and easily implemented approach to identifying issues and brainstorming possible responses. He encourages readers to explore what improvements might alleviate current pressures and frustrations, such as teacher shortages and burnout, declining student performance, and compromised learning time. Whether their goal is to achieve better student engagement, increase parent involvement, or implement personalized learning, readers will develop the mindset to ask the right questions, to fully understand the problem that’s being solved, and to evaluate the probable effectiveness of proposed solutions. Brimming with challenging questions, robust exercises, and eye-opening data, this book is a must-read for education professionals, parent advocates, and anyone passionate about the future of American education.

Semantics in Business Systems begins with a description of what semantics are and how they affect business systems. It examines four main aspects of the application of semantics to systems, specifically: How do we infer meaning from unstructured information, how do application systems make meaning as they operate, how do practitioners uncover meaning in business settings, and how do we understand and communicate what we have deduced? This book illustrates how this applies to the future of application system development, especially how it informs and affects Web services and business rule- based approaches, and how semantics will play out with XML and the semantic Web. The book also contains a quick reference guide to related terms and technologies. It is part of Morgan Kaufmann's series of Savvy Manager's Guides. * Presents an easy and enjoyable introduction to semantics in the context of business IT systems.* Articulates the business value of semantics, while providing relevant introductory technical background.* Describes the semantic underpinnings of data modeling, business rules, enterprise integration, and Web services.* Contains a handy quick-reference guide to technologies and terminology. * For more information, links, and discussions, go to www.savvymanagers.com.
