In What Do We Really Know? Simon Blackburn addresses the twenty most-asked philosophical questions, including 'Can machines think?', 'What is the meaning of life?', 'Is death to be feared?', 'Why be good?', 'What am I?' and 'What do we really know?' Each 3000-word essay examines a question that has eternally perplexed enquiring minds, and provides answers from history's great thinkers.

So What Do They Really Know? Cris Tovani explores the complex issue of monitoring, assessing, and grading students' thinking and performance with fairness and fidelity. Like all teachers, Cris struggles to balance her student-centered instruction with school system mandates. Her recommendations are realistic and practical; she understands that what isn't manageable isn't sustainable. Cris describes the systems and structure she uses in her own classroom and shows teachers how to use assessments to monitor student growth and provide targeted feedback that enables students to master content goals. She also shares ways to bring students into the assessment cycle so they can monitor their own learning, maximizing motivation and engagement. So What Do They Really Know? includes a wealth of information: Lessons from Cris's classroomTemplates showing how teachers can use the workshop model to assess and differentiate instructionStudent work, including samples from linguistically diverse learners, struggling readers, and college-bound seniorsAnchor charts of student thinkingIdeas on how to give feedbackGuidelines that explain how conferring is different from monitoringSuggestions for assessing learning and differentiating instruction during conferencesAdvice for managing ongoing assessmentCris's willingness to share her own struggles continues to be a hallmark of her work. Teachers will recognize their own students and the challenges they face as they join Cris on the journey to figure out how to raise student achievement.

Clear, easy principles to spot what's nonsense and what's reliable Each year, teachers, administrators, and parents face a barrage of new education software, games, workbooks, and professional development programs purporting to be "based on the latest research." While some of these products are rooted in solid science, the research behind many others is grossly exaggerated. This new book, written by a top thought leader, helps everyday teachers, administrators, and family members—who don't have years of statistics courses under their belts—separate the wheat from the chaff and determine which new educational approaches are scientifically supported and worth adopting. Author's first book, Why Don't Students Like School?, catapulted him to superstar status in the field of education Willingham's work has been hailed as "brilliant analysis" by The Wall Street Journal and "a triumph" by The Washington Post Author blogs for The Washington Post and Brittanica.com, and writes a column for American Educator In this insightful book, thought leader and bestselling author Dan Willingham offers an easy, reliable way to discern which programs are scientifically supported and which are the equivalent of "educational snake oil."

Today, it's not uncommon to get the impression that our claims to know are either doomed before they begin or that they have a status that approaches certainty. The pendulum seems to swing from one end to the other, with our educational institutions too often perpetuating both depending on the person being asked. Yet the question of how and if our claims to know are really justified remains central. * Is knowledge a purely social construct without any objective basis, as many claim? * Or, if we do have some basis to believe some of our claims, are we justified in holding those claims with an attitude of certainty, as others in today's environment seem to imply? * And what role do our quick judgments play in those claims? From the tenor of our public debates, one could easily be left with the suspicion that either we can't know anything or that whatever the present state of knowledge is shouldn't be questioned. What Can We Really Know? The Strengths and Limits of Human Understanding aims to bring some balance to the topic, and argues that while we do have reason to believe that a great many of our claims are justified, it's also true that much of what passes for knowledge is a social product and therefore vulnerable to future revision. Exploring how knowledge can be understood, how far science can take us and what its limitations might be, and the status of some of the most recent arguments for God's existence, it will be suggested that a healthy dose of humility should be reincorporated in our public and private debates.

Forget the 10,000 hour rule— what if it’s possible to learn the basics of any new skill in 20 hours or less? Take a moment to consider how many things you want to learn to do. What’s on your list? What’s holding you back from getting started? Are you worried about the time and effort it takes to acquire new skills—time you don’t have and effort you can’t spare? Research suggests it takes 10,000 hours to develop a new skill. In this nonstop world when will you ever find that much time and energy? To make matters worse, the early hours of prac­ticing something new are always the most frustrating. That’s why it’s difficult to learn how to speak a new language, play an instrument, hit a golf ball, or shoot great photos. It’s so much easier to watch TV or surf the web . . . In The First 20 Hours, Josh Kaufman offers a systematic approach to rapid skill acquisition— how to learn any new skill as quickly as possible. His method shows you how to deconstruct com­plex skills, maximize productive practice, and remove common learning barriers. By complet­ing just 20 hours of focused, deliberate practice you’ll go from knowing absolutely nothing to performing noticeably well. Kaufman personally field-tested the meth­ods in this book. You’ll have a front row seat as he develops a personal yoga practice, writes his own web-based computer programs, teaches himself to touch type on a nonstandard key­board, explores the oldest and most complex board game in history, picks up the ukulele, and learns how to windsurf. Here are a few of the sim­ple techniques he teaches: Define your target performance level: Fig­ure out what your desired level of skill looks like, what you’re trying to achieve, and what you’ll be able to do when you’re done. The more specific, the better. Deconstruct the skill: Most of the things we think of as skills are actually bundles of smaller subskills. If you break down the subcompo­nents, it’s easier to figure out which ones are most important and practice those first. Eliminate barriers to practice: Removing common distractions and unnecessary effort makes it much easier to sit down and focus on deliberate practice. Create fast feedback loops: Getting accu­rate, real-time information about how well you’re performing during practice makes it much easier to improve. Whether you want to paint a portrait, launch a start-up, fly an airplane, or juggle flaming chain­saws, The First 20 Hours will help you pick up the basics of any skill in record time . . . and have more fun along the way.

How do scientific conjectures become laws? Why does proof mean different things in different sciences? Do numbers exist, or were they invented? Why do some laws turn out to be wrong?In this wide-ranging book, Brian Davies discusses the basis for scientists' claims to knowledge about the world. He looks at science historically, emphasizing not only the achievements of scientists from Galileo onwards, but also their mistakes. He rejects the claim that all scientific knowledge is provisional, by citing examples from chemistry, biology and geology. A major feature of the book is its defence of the view that mathematics was invented rather than discovered. While experience hasshown that disentangling knowledge from opinion and aspiration is a hard task, this book provides a clear guide to the difficulties.Full of illuminating examples and quotations, and with a scope ranging from psychology and evolution to quantum theory and mathematics, this book brings alive issues at the heart of all science.
