This new edition gives expanded attention to the important symbolic roles of school leaders, including practical suggestions on how leaders can balance cultural goals and values against accountability demands, and features new and powerful case examples throughout. Most important, the authors show how school leaders can transform negative and toxic cultures so that trust, commitment, and sense of unity can prevail. Praise for Shaping School Culture "For those seeking enduring change that is measured in generations rather than months, and to create a legacy rather than a headline, then Shaping School Culture is your guide." —Dr. Douglas B. Reeves, founder, The Leadership and Learning Center, Englewood, CO "Deal and Peterson combine exquisite language, vibrant stories, and sage advice to support school leaders in embracing the paradoxical nature of their work. A 'must read' for all school leaders." —Pam Robbins, educational consultant and author "Once again, the authors have presented practitioners, researchers, professional developers, school coaches, and others with a tremendous resource for renovating and reinvigorating schools." —Karen M. Dyer, Ed.D., group director, Education and Nonprofit Sector Office, Center for CreativeLeadership, Greensboro, NC

    Shaun Allison and Andy Tharby examine the evidence behind what makes great teaching and explore how to implement this in the classroom to make a difference to learning. They distil teaching and learning down into six core principles - challenge, explanation, modelling, practice, feedback and questioning - and show how these can inspire an ethos of excellence and growth, not only in individual classrooms but across a whole school too. Combining robust evidence from a range of fields with the practical wisdom of experienced, effective classroom teachers, the book is a complete toolkit of strategies that teachers can use every lesson to make that lesson count. There are no gimmicky ideas here - just high impact, focused teaching that results in great learning, every lesson, every day. To demonstrate how attainable this is, the book contains a number of case studies from a number of professionals who are successfully embedding a culture of excellence and growth in their schools. Making Every Lesson Count offers an evidence-informed alternative to restrictive Ofsted-driven definitions of great teaching, empowering teachers to deliver great lessons and celebrate high-quality practice. Suitable for all teachers - including trainee teachers, NQTs, and experienced teachers - who want quick and easy ways to enhance their practice and make every lesson count.

    Rhyming text filled with funny, countable examples shows what it means to take one number away from another. Readers are also introduced to the terminology they'll encounter as they learn to subtract.

    Petr Beckmann holds up this mirror, giving the background of the times when pi made progress -- and also when it did not, because science was being stifled by militarism or religious fanaticism.

    Who invented zero? Why are there 60 seconds in a minute? Can a butterfly's wings really cause a storm on the far side of the world? In 50 concise essays, Professor Tony Crilly explains the mathematical concepts that allow use to understand and shape the world around us.

    Birth of a Theorem is Villani’s own account of the years leading up to the award. It invites readers inside the mind of a great mathematician as he wrestles with the most important work of his career.But you don’t have to understand nonlinear Landau damping to love Birth of a Theorem. It doesn’t simplify or overexplain; rather, it invites readers into collaboration. Villani’s diaries, emails, and musings enmesh you in the process of discovery. You join him in unproductive lulls and late-night breakthroughs. You’re privy to the dining-hall conversations at the world’s greatest research institutions. Villani shares his favorite songs, his love of manga, and the imaginative stories he tells his children. In mathematics, as in any creative work, it is the thinker’s whole life that propels discovery—and with Birth of a Theorem, Cédric Villani welcomes you into his.

    Based on a National Magazine Award-winning article, this masterful biography of Hungarian-born Paul Erdos is both a vivid portrait of an eccentric genius and a layman's guide to some of this century's most startling mathematical discoveries.

    In two years, this ring of card savants earned more than three million dollars. Filled with tense action and incredibly close calls, this is a real-life adventure that could have stepped straight out of a Hollywood film.

    With equal parts humanity, insanity, and profanity, Frank Stepnowski, a twenty year veteran of the academic wars, offers unique insight into a world everybody knows about but very few understand. "Step" as he was re-christened by his students, pulls no punches in the classroom, and takes no prisoners in his writing debut. The title, which comes from a line that the author heard many times throughout his career, is both a confession and a confirmation. "I wanted a book," he explains, "that would make people laugh out loud but also open their eyes to just how insane the teaching profession can get. With that in mind, the book is a riotous success, providing searing insight into the classroom and giving an iconoclastic voice to a profession that often goes unheard. Why Are All the Good teachers Crazy? is a wake up call for some, a rallying cry for others, and an invitation to laugh and learn for everyone.Based on actual events, the vivid imagery, colorful characters, and incendiary dialogue of this nuclear powered novel will take readers on a roller coaster ride that they will be talking about long after the ride is over.

    A fun and fascinating look at great scientific paradoxes.   Throughout history, scientists have come up with theories and ideas that just don't seem to make sense.  These we call paradoxes.  The paradoxes Al-Khalili offers are drawn chiefly from physics and astronomy and represent those that have stumped some of the finest minds.  For example, how can a cat be both dead and alive at the same time?  Why will Achilles never beat a tortoise in a race, no matter how fast he runs?  And how can a person be ten years older than his twin?   With elegant explanations that bring the reader inside the mind of those who've developed them, Al-Khalili helps us to see that, in fact, paradoxes can be solved if seen from the right angle.  Just as surely as Al-Khalili narrates the enduring fascination of these classic paradoxes, he reveals their underlying logic.  In doing so, he brings to life a select group of the most exciting concepts in human knowledge.  Paradox is mind-expanding fun.

    Breaking down the symbols themselves, they pose a series of questions: What is energy? What is mass? What has the speed of light got to do with energy and mass? In answering these questions, they take us to the site of one of the largest scientific experiments ever conducted. Lying beneath the city of Geneva, straddling the Franco-Swiss boarder, is a 27 km particle accelerator, known as the Large Hadron Collider. Using this gigantic machine—which can recreate conditions in the early Universe fractions of a second after the Big Bang—Cox and Forshaw will describe the current theory behind the origin of mass.Alongside questions of energy and mass, they will consider the third, and perhaps, most intriguing element of the equation: 'c' - or the speed of light. Why is it that the speed of light is the exchange rate? Answering this question is at the heart of the investigation as the authors demonstrate how, in order to truly understand why E=mc2, we first must understand why we must move forward in time and not backwards and how objects in our 3-dimensional world actually move in 4-dimensional space-time. In other words, how the very fabric of our world is constructed. A collaboration between two of the youngest professors in the UK, Why Does E=mc2? promises to be one of the most exciting and accessible explanations of the theory of relativity in recent years.

    

    Polya, How to Solve It will show anyone in any field how to think straight. In lucid and appealing prose, Polya reveals how the mathematical method of demonstrating a proof or finding an unknown can be of help in attacking any problem that can be reasoned out--from building a bridge to winning a game of anagrams. Generations of readers have relished Polya's deft--indeed, brilliant--instructions on stripping away irrelevancies and going straight to the heart of the problem.
