news tools howard_rheingold rheingold journalism facts factcheck bullshit

shared by Ed Webb on 15 Mar 10 - Cached
  • Students in Howard Rheingold’s journalism class at Stanford recently teamed up with NewsTrust, a nonprofit Web site that enables people to review and rate news articles for their level of quality, in a search for lousy journalism.
  • the News Hunt is a way of getting young journalists to critically examine the work of professionals. For Rheingold, an influential writer and thinker about the online world and the man credited with coining the phrase “virtual community,” it’s all about teaching them “crap detection.”
  • last year Rheingold wrote an important essay about the topic for the San Francisco Chronicle’s Web site
  • ...3 more annotations...
  • What’s at stake is no less than the quality of the information available in our society, and our collective ability to evaluate its accuracy and value. “Are we going to have a world filled with people who pass along urban legends and hoaxes?” Rheingold said, “or are people going to educate themselves about these tools [for crap detection] so we will have collective intelligence instead of misinformation, spam, urban legends, and hoaxes?”
  • I previously called fact-checking “one of the great American pastimes of the Internet age.” But, as Rheingold noted, the opposite is also true: the manufacture and promotion of bullshit is endemic. One couldn’t exist without the other. That makes Rheingold’s essay, his recent experiment with NewsTrust, and his wiki of online critical-thinking tools” essential reading for journalists. (He’s also writing a book about this topic.)
  • I believe if we want kids to succeed online, the biggest danger is not porn or predators—the biggest danger is them not being able to distinguish truth from carefully manufactured misinformation or bullshit

    "It was October and I was standing on the roof of a high rise building in the middle of Shanghai. Flight after flight of stairs interspersed with several elevator journeys had brought me to the summit, and the rooftop on which I now stood served as a primary school playground for hundreds of pupils. As I made my way to the edge of the building I was amazed to find that the only barrier between me and the pavement - 16 stories down - was a small wall, waist height at most. I peered over the edge and can still recall that instant feeling of danger and dizziness washing over my entire body. I stepped back and turned to the Chinese headteacher whose school I was visiting."

    It is almost precisely eighteen years since Donald Rumsfeld uttered his now well-regarded commentary on the danger of "unknown unknowns". At the time his remarks brought more confusion than clarity and reinforced for many a belief that politicians use words to conceal the truth. Somehow though, Donald's words from 2002 seem to fit the world of today, and the challenges confronting educators all too well.

  • Martin Burrett on 29 Dec 16
     
    "Italian psychologist Geatano Kanizsa first described this optical illusion in 1955 as a subjective or illusory contour illusion. The study of such optical illusions has led to an understanding of how the brain and eyes perceive optical information and has been used considerably by artists and designers alike. They show the power of human imagination in filling in the gaps to make implied constructions in our own minds. Kanizsa figures and similar illusions are a really useful way to encourage learners to 'say what they see' and to explain how they see it. It offers a chance for others to become aware of the different views available in a diagram and share their own thoughts without the 'danger' of being wrong; many people see different things."

    Possibly the most dangerous place to spend too much time is inside your comfort zone. Only when we take a risk and step away from the safety of the familiar and the ways we have always done things do we expose ourselves to new ideas and become open to the possibility of learning and discovery. The trouble is having the confidence to take that first step, to embrace discomfort and become open to the risks that come with trying something new.

    "In a few years from now, students in schools all over the world will receive part of their education in virtual learning environments. Wearing VR-goggles the students will be able to enter 3-dimensional, simulated places and situations that they would normally not have access to because it would be too expensive, too dangerous or physically impossible. Teaching via VR-technology is spreading widely and international studies predict that this will revolutionise the way we learn."

commoncore testing standardizedtesting highstakestesting accountability critique

shared by Steve Ransom on 06 Mar 13 - No Cached
  • The promise of the Common Core is dying and teaching and learning are being distorted.  The well that should sustain the Core has been poisoned.
  • Whether or not learning the word ‘commission’ is appropriate for second graders could be debated—I personally think it is a bit over the top.  What is of deeper concern, however, is that during a time when 7 year olds should be listening to and making music, they are instead taking a vocabulary quiz.
  • Real learning occurs in the mind of the learner when she makes connections with prior learning, makes meaning, and retains that knowledge in order to create additional meaning from new information.  In short, with tests we see traces of learning, not learning itself.
  • ...7 more annotations...
  • Teachers are engaged in practices like these because they are pressured and afraid, not because they think the assessments are educationally sound. Their principals are pressured and nervous about their own scores and the school’s scores. Guaranteed, every child in the class feels that pressure and trepidation as well.
  • I am troubled that a company that has a multi-million dollar contract to create tests for the state should also be able to profit from producing test prep materials. I am even more deeply troubled that this wonderful little girl, whom I have known since she was born, is being subject to this distortion of what her primary education should be.
  • The Common Core places an extraordinary emphasis on vocabulary development
  • Parents can expect that the other three will be neglected as teachers frantically try to prepare students for the difficult and high-stakes tests.
  • They see data, not children. 
  • Data should be used as a strategy for improvement, not for accountability
  • A fool with a tool is still a fool.  A fool with a powerful tool is a dangerous fool.

  • If you doubt that we live in a winner-take-all economy and that education is the trump card, consider the vast amounts the affluent spend to teach their offspring.
  • This power spending on the children of the economic elite is usually — and rightly — cited as further evidence of the dangers of rising income inequality.
  • But it may be that the less lavishly educated children lower down the income distribution aren’t the only losers. Being groomed for the winner-take-all economy starting in nursery school turns out to exact a toll on the children at the top, too.
  • ...11 more annotations...
  • There is a lively debate among politicians and professors about whether the economy is becoming more polarized and about the importance of education. Dismissing the value of a college education is one of the more popular clever-sounding contrarian ideas of the moment. And there are still a few die-hards who play down the social significance of rising income inequality.
  • When you translate these abstract arguments into the practical choices we make in our personal lives, however, the intellectual disagreements melt away. We are all spending a lot more money to educate our kids, and the richest have stepped up their spending more than everyone else.
  • spending on children grew over the past four decades and that it became more unequal. “Our findings also show that investment grew more unequal over the study period: parents near the top of the income distribution spent more in real dollars near the end of the 2000s than in the early 1970s, and the gap in spending between rich and poor grew.”
  • But it turns out that the children being primed for that race to the top from preschool onward aren’t in such great shape, either.
  • “What we are finding again and again, in upper-middle-class school districts, is the proportion who are struggling are significantly higher than in normative samples,” she said. “Upper-middle-class kids are an at-risk group.”
  • troubled rich kids. “I was looking for a comparison group for the inner-city kids,” Dr. Luthar told me. “And we happened to find that substance use, depression and anxiety, particularly among the girls, were much higher than among inner-city kids.”
  • “I Can, Therefore I Must: Fragility in the Upper Middle Class,” and it describes a world in which the opportunities, and therefore the demands, for upper-middle-class children are infinite.
  • “It is an endless cycle, starting from kindergarten,” Dr. Luthar said. “The difficulty is that you have these enrichment activities. It is almost as if, if you have the opportunity, you must avail yourself of it. The pressure is enormous.”
  • these parents and children are responding rationally to a hyper-competitive world economy.
  • “When we talk to youngsters now, when they set goals for themselves, they want to match up to at least what their parents have achieved, and that is harder to do.”
  • we live in individualistic democracies whose credo is that anyone can be a winner if she tries. But we are also subject to increasingly fierce winner-take-all forces, which means the winners’ circle is ever smaller, and the value of winning is ever higher.

  • There are keynote speakers—often the people who created the technology at hand or crafted a given language. There are the regular speakers, often paid not at all or in airfare, who present some idea or technique or approach. Then there are the panels, where a group of people are lined up in a row and forced into some semblance of interaction while the audience checks its e-mail.
  • Fewer than a fifth of undergraduate degrees in computer science awarded in 2012 went to women, according to the National Center for Women & Information Technology
  • The average programmer is moderately diligent, capable of basic mathematics, has a working knowledge of one or more programming languages, and can communicate what he or she is doing to management and his or her peers
  • ...16 more annotations...
  • The true measure of a language isn’t how it uses semicolons; it’s the standard library of each language. A language is software for making software. The standard library is a set of premade software that you can reuse and reapply.
  • A coder needs to be able to quickly examine and identify which giant, complex library is the one that’s the most recently and actively updated and the best match for his or her current needs. A coder needs to be a good listener.
  • Code isn’t just obscure commands in a file. It requires you to have a map in your head, to know where the good libraries, the best documentation, and the most helpful message boards are located. If you don’t know where those things are, you will spend all of your time searching, instead of building cool new things.
  • Some tools are better for certain jobs.
  • C is a simple language, simple like a shotgun that can blow off your foot. It allows you to manage every last part of a computer—the memory, files, a hard drive—which is great if you’re meticulous and dangerous if you’re sloppy
  • Object-oriented programming is, at its essence, a filing system for code.
  • Where C tried to make it easier to do computer things, Smalltalk tried to make it easier to do human things.
  • Style and usage matter; sometimes programmers recommend Strunk & White’s The Elements of Style—that’s right, the one about the English language. Its focus on efficient usage resonates with programmers. The idiom of a language is part of its communal identity.
  • Coding is a culture of blurters.
  • Programmers carve out a sliver of cognitive territory for themselves and go to conferences, and yet they know their position is vulnerable.
  • Programmers are often angry because they’re often scared.
  • Programming is a task that rewards intense focus and can be done with a small group or even in isolation.
  • For a truly gifted programmer, writing code is a side effect of thought
  • As a class, programmers are easily bored, love novelty, and are obsessed with various forms of productivity enhancement.
  • “Most programming languages are partly a way of expressing things in terms of other things and partly a basic set of given things.”
  • Of course, while we were trying to build a bookstore, we actually built the death of bookstores—that seems to happen a lot in the business. You set out to do something cool and end up destroying lots of things that came before.

  • by ‘Making Thinking Visible’ (MTV) can help here. MTV strategies offer two advantages to teachers and learners. Importantly they provide structure to thinking and encourage a deeper engagement with concepts and ideas. They also allow the thinking that is occurring to be made visible and thus a part of the assessment process

    The maker movement and with it maker-centered learning brings new possibilities and challenges into the classroom. It has spawned makerspaces and students are busy designing and making products. The danger with all this frenzied making is that it is very easy to miss the point, to focus on the product and not the journey.
