Chief Rabbi: atheism has failed. Only religion can defeat the new barbarians ... - 0 views

  • reading the new atheists.
  • Where is there the remotest sense that they have grappled with the real issues, which have nothing to do with science and the literal meaning of scripture and everything to do with the meaningfulness or otherwise of human life, the existence or non-existence of an objective moral order, the truth or falsity of the idea of human freedom, and the ability or inability of society to survive without the rituals, narratives and shared practices that create and sustain the social bond?
  • religion has social, cultural and political consequences, and you cannot expect the foundations of western civilisation to crumble and leave the rest of the building intact. That is what the greatest of all atheists, Nietzsche, understood
  • ...10 more annotations...
  • The history of Europe since the 18th century has been the story of successive attempts to find alternatives to God as an object of worship, among them the nation state, race and the Communist Manifesto. After this cost humanity two world wars, a Cold War and a hundred million lives, we have turned to more pacific forms of idolatry, among them the market, the liberal democratic state and the consumer society,
  • This is what a society built on materialism, individualism and moral relativism looks like. It maximises personal freedom but at a cost.
  • This freedom, energising and exciting as it is, is also profoundly disintegrative, making it very difficult for individuals to find any stable communal support, very difficult for any community to count on the responsible participation of its individual members. It opens solitary men and women to the impact of a lowest common denominator, commercial culture.’
  • In one respect the new atheists are right. The threat to western freedom in the 21st century is not from fascism or communism but from a religious fundamentalism combining hatred of the other, the pursuit of power and contempt for human rights.
  • But the idea that this can be defeated by individualism and relativism is naive almost beyond belief. Humanity has been here before.
  • The barbarians win. They always do.
  • The new barbarians are the fundamentalists who seek to impose a single truth on a plural world. Though many of them claim to be religious, they are actually devotees of the will to power. Defeating them will take the strongest possible defence of freedom, and strong societies are always moral societies
  • That does not mean that they need be religious. It is just that, in the words of historian Will Durant, ‘There is no significant example in history, before our time, of a society successfully maintaining moral life without the aid of religion.’
  • I have not yet found a secular ethic capable of sustaining in the long run a society of strong communities and families on the one hand, altruism, virtue, self-restraint, honour, obligation and trust on the other
  • A century after a civilisation loses its soul it loses its freedom also. That should concern all of us, believers and non-believers alike.

C. S. Lewis, Evangelical Rock Star - NYTimes.com - 0 views

  • the text for which Lewis is best known is his “Chronicles of Narnia.” And what “Narnia” offers is not theological simplicity, but complexity. The God represented in these books is not quite real (it’s fiction) and yet more real than the books pretend (that’s not a lion, it’s God).
  • In “Mere Christianity,” Lewis wrote that to pretend helps one to experience God as real. In “Narnia” he offered a way to pretend — by depicting a God who is so explicitly not a God from an ordinary human church. Aslan keeps God safe from human clumsiness and error.
  • What does it mean that our society places such a premium on fantasy and imagination?
  • ...6 more annotations...
  • This suggests that we imagine a complex reality in which things might be true — materially, spiritually, psychologically
  • Westerners, by contrast, not only tolerate fantasy play but actively encourage it, for adults as well as for children. We are novel readers, movie watchers and game players.
  • “Inventive pretend,” in which children pretend the fantastic or impossible (enchanted princesses, dragon hunters) “is rarely — if ever — observed in non-industrialized or traditional cultures,”
  • Science leads us to draw a sharp line between what is real and what is unreal. At the same time, we live in an age in which we are exquisitely aware that there are many theories, both religious and scientific, to explain the world, and many ways to be human.
  • Probably fiction does for us what the vision of Aslan did for Bob: it helps us to learn what we find emotionally true in the face of irreconcilable contradictions.
  • fiction teaches us how to think about what we take to be true. In the cacophony of an information-soaked age, we need it.

Archimedes - Separating Myth From Science - NYTimes.com - 0 views

  • A panoply of devices and ideas are named after Archimedes. Besides the Archimedes screw, there is the Archimedes principle, the law of buoyancy that states the upward force on a submerged object equals the weight of the liquid displaced. There is the Archimedes claw, a weapon that most likely did exist, grabbing onto Roman ships and tipping them over. And there is the Archimedes sphere, a forerunner of the planetarium — a hand-held globe that showed the constellations as well as the locations of the sun and the planets in the sky.
  • Dr. Rorres said the singular genius of Archimedes was that he not only was able to solve abstract mathematics problems, but also used mathematics to solve physics problems, and he then engineered devices to take advantage of the physics. “He came up with fundamental laws of nature, proved them mathematically and then was able to apply them,” Dr. Rorres said.

Skinner Marketing: We're the Rats, and Facebook Likes Are the Reward - Bill Davidow - T... - 0 views

  • the age of Skinnerian Marketing. Future applications making use of big data, location, maps, tracking of a browser's interests, and data streams coming from mobile and wearable devices, promise to usher in the era of unprecedented power in the hands of marketers, who are no longer merely appealing to our innate desires, but programming our behaviors.
  • In the 1930's, B. F. Skinner developed the concept of operant conditioning. He put pigeons and rats in Skinner boxes to study how he could modify their behavior using rewards and punishments.
  • Skinner's techniques of operant conditioning and his notorious theory of behavior modification were denounced by his critics 70 years ago as fascist, manipulative vehicles that could be used for government control.
  • ...6 more annotations...
  • They were right about control but wrong about the controllers. Our Internet handlers, not government, are using operant conditioning to modify our behavior today.
  • we now know how to design cue, activity, and reward systems to more effectively leverage our brain chemistry and program human behavior.
  • The beauty of the Internet is that by combining big data, behavioral targeting, wearable and mobile devices, and GPS, application developers can design more effective operant conditioning environments and keep us in virtual Skinner boxes as long as we have a smart phone in our pockets.
  • Operant conditioning techniques will and are currently being used to program the behavior of susceptible Internet users -- young men who play MMORPG (Massively Multiplayer Online Role-Playing Games) for forty hours a week, women who commit hours to social networks, shoppers seeking the thrill of a deal, and poker players.
  • As smart devices become integrated into our lives, retailers who will know where we are standing in stores and fast food restaurants and bars will find ways to provide us with cues to trigger behaviors.
  • The real question is how many hundreds of millions of us will become susceptible to what I believe will prove to be history's most potent marketing techniques.

How Memory Works: Interview with Psychologist Daniel L. Schacter | History News Network - 2 views

  • knowledge from a scientific perspective of how human memory works can be instructive to historians.
  • Memory is much more than a simple retrieval system, as Dr. Schacter has demonstrated in his research. Rather, the nature of memory is constructive and influenced by a person’s current state as well as intervening emotions, beliefs, events and other factors since a recalled event.
  • Dr. Schacter is William R. Kenan, Jr. Professor of Psychology at Harvard University. His books include Searching for Memory: The Brain, The Mind, and The Past, and The Seven Sins of Memory: How the Mind Forgets and Remembers, both winners of the American Psychological Association’s William James Book Award, and Forgotten Ideas, Neglected Pioneers: Richard Semon and the Story of Memory. He also has written hundreds of articles on memory and related matters. He was elected a Fellow of the American Academy of Arts and Sciences in 1996 and the National Academy of Sciences in 2013.
  • ...16 more annotations...
  • that memory is not a video recorder [but that] it’s a constructive activity that is in many ways accurate but prone to interesting errors and distortions. It’s the constructive side of memory that is most relevant to historians.
  • Is it the case then that our memories constantly change every time we access them?
  • That certainly can happen depending on how you recount a memory. What you emphasize. What you exaggerate. What you don’t talk about. All of those things will shape and sculpt the memory for future use. Certainly the potential is there.
  • Research on memory shows that the more distant in time the event, the more prone to inaccuracy the memory. There are several experiments when subjects recorded impressions of an event soon afterward, then a year later and then a few years later, and the memory changed.Yes. It’s not that the information is lost but, as the memory weakens, you become more prone to incorporating other kinds of information or mixing up elements of other events. This has been seen, for example, in the study of flashbulb memories. Where were you when Kennedy was shot? Where were you when you heard about 9/11?
  • Isn’t there a tendency to add details or information that may make the story more convincing or interesting later?Yes. That’s more a social function of memory. It may be that you draw on your general knowledge and probable information from your memory in a social context where there may be social demands that lead you distort the memory.
  • What are the different memory systems?
  • What is the difference between working memory and permanent memory?Working memory is really a temporary memory buffer where you hold onto information, manipulate information, use it, and it’s partly a gateway to long-term memory and also a buffer that you use when you’re retrieving information from long-term memory and that information temporarily resides in working memory, so to speak.
  • Your discussion of the testimony of White House Counsel John Dean about Watergate is illuminating. There was a perception that Dean had a photographic memory and he testified in rich detail about events. Yet later studies of White House tape recordings revealed that he was often inaccurate.
  • He was perceived because of all the detail with which he reported events and the great confidence to be something analogous to a human tape recorder. Yet there was interesting work done by psychologist Ulric Neisser who went back and analyzed what Dean said at the hearings as compared to available information on the White House taping system and basically found many and significant discrepancies between what Dean remembered and what was actually said. He usually had the gist and the meaning and overall significance right, but the exact details were often quite different in his memory than what actually was said.
  • That seems to get into the area of false memories and how they present problems in the legal system.We know from DNA exonerations of people wrongfully convicted of crimes that a large majority of those cases -- one of the more recent estimates is that in the first 250 cases of 2011 DNA exonerations, roughly 70 to 75 percent of those individuals were convicted on the basis of faulty eyewitness memory.
  • One of the interesting recent lines of research that my lab has been involved in over the past few years has been looking at similarities between what goes on between the brain and mind when we remember past events on the one hand and imagine events that might occur in the future or might have occurred in the past. What we have found, particularly with brain scanning studies, is that you get very similar brain networks coming online when you remember past events and imagine future events, for example. Many of the same brain regions or network of structures come online, and this has helped us understand more why, for example, imagining events that might have occurred can be so harmful to memory accuracy because when you imagine, you’re recruiting many of the same brain regions as accessed when you actually remember. So it’s not surprising that some of these imagined events can actually turn into false memories under the right circumstances.
  • One reasonably well accepted distinction involves episodic memory, the memory for personal experience; semantic memory, the memory for general knowledge; and procedural memory, the memory for skills and unconscious forms of memory.Those are three of the major kinds of memory and they all have different neural substrates.
  • One of the points from that Ross Perot study is that his supporters often misremembered what they felt like at the time he reported he had dropped out of the race. The nature of that misremembering depended on their state at the time they were remembering and what decisions they had made about Perot in the interim affected how they reconstructed their earlier memories.Again, that makes nicely the point that our current emotions and current appraisals of a situation can feed back into our reconstruction of the past and sometimes lead us to distort our memories so that they better support our current emotions and our current selves. We’re often using memories to justify what we currently know, believe and feel.
  • memory doesn’t work like a video camera or tape recorder.That is the main point. Our latest thinking on this is the idea that one of the major functions of memory is to support our ability to plan for the future, to imagine the future, and to use our past experiences in a flexible way to simulate different outcomes of events.
  • flexibility of memory is something that makes it useful to support this very important ability to run simulations of future events. But that very flexibility might be something that contributes to some of the memory distortion we talked about. That has been prominent in the last few years in my thinking about the constructive nature of memory.
  • The historian Daniel Aaron told his students “we remember what’s important.” What do you think of that comment?I think that generally holds true. Certainly, again, more important memories tend to be more significant with more emotional arousal and may elicit “deeper processing”, as we call it in cognitive psychology

Ben Bernanke to Princeton Grads: The World Isn't Fair (and You All Got Lucky) - Jordan ... - 0 views

  • We have been taught that meritocratic institutions and societies are fair. Putting aside the reality that no system, including our own, is really entirely meritocratic, meritocracies may be fairer and more efficient than some alternatives. But fair in an absolute sense? Think about it. A meritocracy is a system in which the people who are the luckiest in their health and genetic endowment; luckiest in terms of family support, encouragement, and, probably, income; luckiest in their educational and career opportunities; and luckiest in so many other ways difficult to enumerate -- these are the folks who reap the largest rewards.
  • Life is amazingly unpredictable; any 22-year-old who thinks he or she knows where they will be in 10 years, much less in 30, is simply lacking imagination.
  • In so many words: You, Princeton Class of 2013, got lucky, and never forget it.
  • ...5 more annotations...
  • You're here because you're smart, but you're smart because you're fortunate.
  • The only way for even a putative meritocracy to hope to pass ethical muster, to be considered fair, is if those who are the luckiest in all of those respects also have the greatest responsibility to work hard, to contribute to the betterment of the world, and to share their luck with others.
  • Whatever life may have in store for you, each of you has a grand, lifelong project, and that is the development of yourself as a human being.
  • Those most worthy of admiration are those who have made the best use of their advantages or, alternatively, coped most courageously with their adversities.
  • Speaking as somebody who has been happily married for 35 years, I can't imagine any choice more consequential for a lifelong journey than the choice of a traveling companion.

The Faulty Logic of the 'Math Wars' - NYTimes.com - 0 views

  • The American philosopher Wilfrid Sellars was challenging this assumption when he spoke of “material inferences.” Sellars was interested in inferences that we can only recognize as valid if we possess certain bits of factual knowledge.
  • If we make room for such material inferences, we will be inclined to reject the view that individuals can reason well without any substantial knowledge of, say, the natural world and human affairs. We will also be inclined to regard the specifically factual content of subjects such as biology and history as integral to a progressive education.
  • according to Wittgenstein, is why it is wrong to understand algorithm-based calculations as expressions of nothing more than “mental mechanisms.” Far from being genuinely mechanical, such calculations involve a distinctive kind of thought.
  • ...3 more annotations...
  • That the use of standard algorithms isn’t merely mechanical is not by itself a reason to teach them. It is important to teach them because, as we already noted, they are also the most elegant and powerful methods for specific operations. This means that they are our best representations of connections among mathematical concepts. Math instruction that does not teach both that these algorithms work and why they do is denying students insight into the very discipline it is supposed to be about.
  • There is a moral here for progressive education that reaches beyond the case of math. Even if we sympathize with progressivists in wanting schools to foster independence of mind, we shouldn’t assume that it is obvious how best to do this. Original thought ranges over many different domains, and it imposes divergent demands as it does so. Just as there is good reason to believe that in biology and history such thought requires significant factual knowledge, there is good reason to believe that in mathematics it requires understanding of and facility with the standard algorithms.
  • there is also good reason to believe that when we examine further areas of discourse we will come across yet further complexities. The upshot is that it would be naïve to assume that we can somehow promote original thinking in specific areas simply by calling for subject-related creative reasoning

The Way to Produce a Person - NYTimes.com - 0 views

  • the brain is a malleable organ. Every time you do an activity, or have a thought, you are changing a piece of yourself into something slightly different than it was before. Every hour you spend with others, you become more like the people around you.
  • Gradually, you become a different person. If there is a large gap between your daily conduct and your core commitment, you will become more like your daily activities and less attached to your original commitment. You will become more hedge fund, less malaria.
  • I would worry about turning yourself into a means rather than an end. If you go to Wall Street mostly to make money for charity, you may turn yourself into a machine for the redistribution of wealth. You may turn yourself into a fiscal policy.

Moral Puzzles That Tots Struggle With | Mind & Matter - WSJ.com - 2 views

  • children are "intuitive sociologists" trying to make sense of the social world. We already know that very young children make up theories about everyday physics, psychology and biology. Dr. Rhodes thinks that they have theories about social groups, too.
  • children aren't just biased against other racial groups: They also assume that everybody else will be biased against other groups. And this extends beyond race, gender and religion to the arbitrary realm of Zazes and Flurps.
  • intuitive social theory may even influence how children develop moral distinctions
  • ...4 more annotations...
  • Back in the 1980s, Judith Smetana and colleagues discovered that very young kids could discriminate between genuinely moral principles and mere social conventions. First, the researchers asked about everyday rules—a rule that you can't be mean to other children, for instance, or that you have to hang up your clothes. The children said that, of course, breaking the rules was wrong. But then the researchers asked another question: What would you think if teachers and parents changed the rules to say that being mean and dropping clothes were OK? Children as young as 2 said that, in that case, it would be OK to drop your clothes, but not to be mean. No matter what the authorities decreed, hurting others, even just hurting their feelings, was always wrong. It's a strikingly robust result—true for children from Brazil to Korea.
  • in the new study, Dr. Rhodes asked similar moral questions about the Zazes and Flurps. The 4-year-olds said it would always be wrong for Zazes to hurt the feelings of others in their group. But if teachers decided that Zazes could hurt Flurps' feelings, then it would be OK to do so. Intrinsic moral obligations only extended to members of their own group.
  • The 4-year-olds demonstrate the deep roots of an ethical tension that has divided philosophers for centuries. We feel that our moral principles should be universal, but we simultaneously feel that there is something special about our obligations to our own group, whether it's a family, clan or country.
  • you don't have to be taught to prefer your own group—you can pick that up fine by yourself. But we do have to teach our children how to widen the moral circle, and to extend their natural compassion and care even to the Flurps.

Philosophy isn't dead yet | Raymond Tallis | Comment is free | The Guardian - 1 views

  • Fundamental physics is in a metaphysical mess and needs help. The attempt to reconcile its two big theories, general relativity and quantum mechanics, has stalled for nearly 40 years. Endeavours to unite them, such as string theory, are mathematically ingenious but incomprehensible even to many who work with them. This is well known.
  • A better-kept secret is that at the heart of quantum mechanics is a disturbing paradox – the so-called measurement problem, arising ultimately out of the Uncertainty Principle – which apparently demonstrates that the very measurements that have established and confirmed quantum theory should be impossible. Oxford philosopher of physics David Wallace has argued that this threatens to make quantum mechanics incoherent which can be remedied only by vastly multiplying worlds.
  • there is the failure of physics to accommodate conscious beings. The attempt to fit consciousness into the material world, usually by identifying it with activity in the brain, has failed dismally, if only because there is no way of accounting for the fact that certain nerve impulses are supposed to be conscious (of themselves or of the world) while the overwhelming majority (physically essentially the same) are not. In short, physics does not allow for the strange fact that matter reveals itself to material objects (such as physicists).
  • ...3 more annotations...
  • then there is the mishandling of time. The physicist Lee Smolin's recent book, Time Reborn, links the crisis in physics with its failure to acknowledge the fundamental reality of time. Physics is predisposed to lose time because its mathematical gaze freezes change. Tensed time, the difference between a remembered or regretted past and an anticipated or feared future, is particularly elusive. This worried Einstein: in a famous conversation, he mourned the fact that the present tense, "now", lay "just outside of the realm of science".
  • Recent attempts to explain how the universe came out of nothing, which rely on questionable notions such as spontaneous fluctuations in a quantum vacuum, the notion of gravity as negative energy, and the inexplicable free gift of the laws of nature waiting in the wings for the moment of creation, reveal conceptual confusion beneath mathematical sophistication. They demonstrate the urgent need for a radical re-examination of the invisible frameworks within which scientific investigations are conducted.
  • we should reflect on how a scientific image of the world that relies on up to 10 dimensions of space and rests on ideas, such as fundamental particles, that have neither identity nor location, connects with our everyday experience. This should open up larger questions, such as the extent to which mathematical portraits capture the reality of our world – and what we mean by "reality".

Belief Is the Least Part of Faith - NYTimes.com - 1 views

  • Why do people believe in God? What is our evidence that there is an invisible agent who has a real impact on our lives? How can those people be so confident?
  • These are the questions that university-educated liberals ask about faith. They are deep questions. But they are also abstract and intellectual. They are philosophical questions. In an evangelical church, the questions would probably have circled around how to feel God’s love and how to be more aware of God’s presence. Those are fundamentally practical questions.
  • The role of belief in religion is greatly overstated, as anthropologists have long known. In 1912, Émile Durkheim, one of the founders of modern social science, argued that religion arose as a way for social groups to experience themselves as groups. He thought that when people experienced themselves in social groups they felt bigger than themselves, better, more alive — and that they identified that aliveness as something supernatural. Religious ideas arose to make sense of this experience of being part of something greater. Durkheim thought that belief was more like a flag than a philosophical position: You don’t go to church because you believe in God; rather, you believe in God because you go to church.
  • ...4 more annotations...
  • In fact, you can argue that religious belief as we now conceptualize it is an entirely modern phenomenon. As the comparative religion scholar Wilfred Cantwell Smith pointed out, when the King James Bible was printed in 1611, “to believe” meant something like “to hold dear.” Smith, who died in 2000, once wrote: “The affirmation ‘I believe in God’ used to mean: ‘Given the reality of God as a fact of the universe, I hereby pledge to Him my heart and soul. I committedly opt to live in loyalty to Him. I offer my life to be judged by Him, trusting His mercy.’ Today the statement may be taken by some as meaning: ‘Given the uncertainty as to whether there be a God or not, as a fact of modern life, I announce that my opinion is yes.’ ”
  • secular Americans often think that the most important thing to understand about religion is why people believe in God, because we think that belief precedes action and explains choice. That’s part of our folk model of the mind: that belief comes first.
  • that was not really what I saw after my years spending time in evangelical churches. I saw that people went to church to experience joy and to learn how to have more of it. These days I find that it is more helpful to think about faith as the questions people choose to focus on, rather than the propositions observers think they must hold.
  • If you can sidestep the problem of belief — and the related politics, which can be so distracting — it is easier to see that the evangelical view of the world is full of joy. God is good. The world is good. Things will be good, even if they don’t seem good now. That’s what draws people to church. It is understandably hard for secular observers to sidestep the problem of belief. But it is worth appreciating that in belief is the reach for joy, and the reason many people go to church in the first place.

Stanford Magazine - History Detected - May/June 2013 - 2 views

  • an approach developed at Stanford's Graduate School of Education that's rapidly gaining adherents across the country
  • trial studies of the Stanford program demonstrated that when high school students engage regularly with challenging primary source documents, they not only make significant gains learning and retaining historical material, they also markedly improve their reading comprehension and critical thinking.
  • Colglazier builds his thought-provoking classes using an online tool called Reading Like a Historian. Designed by the Stanford History Education Group under Professor Sam Wineburg, the website offers 87 flexible lesson plans featuring documents from the Library of Congress
  • ...15 more annotations...
  • "Textbooks are useful as background narrative. It's difficult to talk about the Gulf of Tonkin Resolution if students don't know where Vietnam is, or the Lincoln-Douglas debates if they don't know who Abe Lincoln was before he was Daniel Day-Lewis.
  • The website's lessons have been downloaded 800,000 times and spawned a lively online community of history educators grateful for the camaraderie
  • just 30 percent of the people who teach history-related courses in U.S. public high schools both majored in the field and are certified to teach it.
  • " By reading these challenging documents and discovering history for themselves, he says, "not only will they remember the content, they'll develop skills for life."
  • Teachers can download the lessons and adapt them for their own purposes, free of charge. Students learn how to examine documents critically, just as historians would, in order to answer intriguing questions: Did Pocahontas really rescue John Smith? Was Abraham Lincoln a racist? Who blinked first in the Cuban Missile Crisis, the Russians or the Americans?
  • But when a ten-pound textbook becomes the script for a whole year's worth of instruction, a precious learning opportunity is lost. "Many students go through their entire middle and high school and never encounter the actual voice of a historical participant,"
  • The Common Core curriculum will bring radical changes in the standardized state tests that youngsters have been taking for decades. Instead of filling in multiple-choice bubbles, they will be expected to write out short answers that demonstrate their ability to analyze texts, and then cite those texts to support arguments—the exact skills that Reading Like a Historian fosters.
  • Wineburg realized that the art of historical thinking is not something that comes naturally to most people; it has to be cultivated. Students have to be taught to look at the source of a document before reading it, figure out the context in which it was written, and cross-check it with other sources before coming to a conclusion.
  • In 2008, Reisman was ready to conduct a test of the curriculum at five schools in the San Francisco Unified School District. As expected, students in the test classes showed an increased ability to retain historical knowledge, as well as a greater appreciation for history, compared to the control group. What took everyone by surprise, though, was how much the test students advanced in basic reading.
  • Fremont 11th grader Ayanna Black agrees. "In other history courses I have taken, I wasn't able to fully understand what was going on. It seemed that it was just a bunch of words I had to memorize for a future test," she says. "Now that I contextualize the information I am given, it helps me understand not only what is being said but also the reason behind it." The approach, she says, "leads me to remembering the information out of curiosity, rather than trying to pass a test."
  • Scholars in the Stanford History Education Group hope to develop more online lesson plans in world history
  • Wineburg devoured history books as a kid and did well in Advanced Placement courses at his public high school. But when he entered Brown University, he was shocked at how ill-prepared he was in the subject. Employed after college as a high school history teacher, he saw similar weaknesses in his students. "The best ones could repeat what the text said," he recalls, "but when I asked them to critically examine whether they believed the text, I could have been speaking Martian."
  • Wineburg and his PhD students have teamed up with the library on another project: a website called Beyond the Bubble,where teachers can learn how to evaluate their students using short written tests called History Assessments of Thinking. Each HAT asks students to consider a historical document—a letter drawn from the archives of the NAACP, for example—and justify their conclusions about it in three or four sentences. By scanning the responses, teachers can determine quickly whether their pupils are grasping basic concepts.
  • Wineburg hopes to make Reading Like a Historian lesson plans completely paperless, with exercise sheets that can be filled out on a laptop or tablet computer.
  • Though the work has been hard in history this year, she appreciates what it's taught her. "I've learned that you don't just read what is put in front of you and accept it, which is what I had been doing with my textbook all summer," she explains.
