EarthEcho Expeditions: What's the Catch? - 5 views

  •  
    "Teachers in England are being invited to join a professional development opportunity through EarthEcho International sponsored by the Northrop Grumman Foundation. The 'EarthEcho Expeditions: What's the Catch?' programme leverages the rich Cousteau legacy of exploration and discovery to bring Science, Technology, Engineering and Mathematics (STEM) education alive for today's 21st-century learners and their educators. The free, expenses-paid opportunity is planned to allow secondary school teachers to participate as Expedition Fellows to learn first-hand from scientists and engineers the consequences of fisheries mismanagement and how this can be changed for the better with new technological approaches and discoveries."

      Where does this statistic come from?
  • Twitter is a rare case: it has arranged to archive all of its tweets at the Library of Congress.
  • Sometimes when you try to visit a Web page what you see is an error message: “Page Not Found.” This is known as “link rot,”
  • ...14 more annotations...
  • Or maybe the page has been moved and something else is where it used to be. This is known as “content drift,”
  • For the law and for the courts, link rot and content drift, which are collectively known as “reference rot,” have been disastrous.
  • According to a 2014 study conducted at Harvard Law School, “more than 70% of the URLs within the Harvard Law Review and other journals, and 50% of the URLs within United States Supreme Court opinions, do not link to the originally cited information.”
  • one in five links provided in the notes suffers from reference rot
  • 1961, in Cambridge, J. C. R. Licklider, a scientist at the technology firm Bolt, Beranek and Newman, began a two-year study on the future of the library, funded by the Ford Foundation and aided by a team of researchers that included Marvin Minsky, at M.I.T.
  • Licklider envisioned a library in which computers would replace books and form a “network in which every element of the fund of knowledge is connected to every other element.”
  • Licklider’s two-hundred-page Ford Foundation report, “Libraries of the Future,” was published in 1965.
  • Kahle enrolled at M.I.T. in 1978. He studied computer science and engineering with Minsky.
  • Vint Cerf, who worked on ARPAnet in the seventies, and now holds the title of Chief Internet Evangelist at Google, has started talking about what he sees as a need for “digital vellum”: long-term storage. “I worry that the twenty-first century will become an informational black hole,” Cerf e-mailed me. But Kahle has been worried about this problem all along.
  • The Internet Archive is also stocked with Web pages that are chosen by librarians, specialists like Anatol Shmelev, collecting in subject areas, through a service called Archive It, at archive-it.org, which also allows individuals and institutions to build their own archives.
  • Illien told me that, when faced with Kahle’s proposal, “national libraries decided they could not rely on a third party,” even a nonprofit, “for such a fundamental heritage and preservation mission.”
  • screenshots from Web archives have held up in court, repeatedly.
  • Perma.cc has already been adopted by law reviews and state courts; it’s only a matter of time before it’s universally adopted as the standard in legal, scientific, and scholarly citation.
  • It’s not possible to go back in time and rewrite the HTTP protocol, but Van de Sompel’s work involves adding to it. He and Michael Nelson are part of the team behind Memento, a protocol that you can use on Google Chrome as a Web extension, so that you can navigate from site to site, and from time to time. He told me, “Memento allows you to say, ‘I don’t want to see this link where it points me to today; I want to see it around the time that this page was written, for example.’ ”

The Elusive Big Idea - NYTimes.com - 51 views

  • If our ideas seem smaller nowadays, it’s not because we are dumber than our forebears but because we just don’t care as much about ideas as they did. In effect, we are living in an increasingly post-idea world — a world in which big, thought-provoking ideas that can’t instantly be monetized are of so little intrinsic value that fewer people are generating them and fewer outlets are disseminating them, the Internet notwithstanding. Bold ideas are almost passé.
  • we live in a post-Enlightenment age in which rationality, science, evidence, logical argument and debate have lost the battle in many sectors, and perhaps even in society generally, to superstition, faith, opinion and orthodoxy. While we continue to make giant technological advances, we may be the first generation to have turned back the epochal clock — to have gone backward intellectually from advanced modes of thinking into old modes of belief.
  • Post-Enlightenment refers to a style of thinking that no longer deploys the techniques of rational thought. Post-idea refers to thinking that is no longer done, regardless of the style.
  • ...10 more annotations...
  • In the past, we collected information not simply to know things. That was only the beginning. We also collected information to convert it into something larger than facts and ultimately more useful — into ideas that made sense of the information. We sought not just to apprehend the world but to truly comprehend it, which is the primary function of ideas. Great ideas explain the world and one another to us.
  • These ideas enabled us to get our minds around our existence and attempt to answer the big, daunting questions of our lives.
  • But if information was once grist for ideas, over the last decade it has become competition for them.
  • In effect, we are living within the nimbus of an informational Gresham’s law in which trivial information pushes out significant information, but it is also an ideational Gresham’s law in which information, trivial or not, pushes out ideas.
  • We prefer knowing to thinking because knowing has more immediate value. It keeps us in the loop
  • For one thing, social networking sites are the primary form of communication among young people, and they are supplanting print, which is where ideas have typically gestated. For another, social networking sites engender habits of mind that are inimical to the kind of deliberate discourse that gives rise to ideas.
  • Indeed, the gab of social networking tends to shrink one’s universe to oneself and one’s friends, while thoughts organized in words, whether online or on the page, enlarge one’s focus.
  • But because they are scientists and empiricists rather than generalists in the humanities, the place from which ideas were customarily popularized, they suffer a double whammy: not only the whammy against ideas generally but the whammy against science, which is typically regarded in the media as mystifying at best, incomprehensible at worst. A generation ago, these men would have made their way into popular magazines and onto television screens.
  • there is a vast difference between profit-making inventions and intellectually challenging thoughts.
  • There won’t be anything we won’t know. But there will be no one thinking about it.

Startup turns carbon dioxide into fuels - 1 views

  • Today, carbon dioxide (CO2) is a hot topic. Scientists around the globe are searching for ways to store, dispose of, or prevent the formation of the greenhouse gas, which is a major driver of global climate change. Liquid Light hopes to take this concept one step further and harness waste CO2 as a source of carbon to make industrial chemicals and fuels.
  • Take CO2 and mix it in a water-filled chamber with an electrode and a catalyst. The ensuing chemical reaction converts CO2 into a new molecule, methanol, which can be used as a fuel, an industrial solvent or a starting material for the manufacture of other chemicals.
  • Bocarsly likes to call the process "reverse combustion" because it is like running a burning reaction backwards. Instead of burning fuel and oxygen to produce CO2, the CO2 converts back into fuel and oxygen.
  • ...2 more annotations...
  • Cole set up a flask containing a solution of CO2 and a pyridinium catalyst dissolved in water. In place of sunlight, which emits a broad spectrum of wavelengths of light, she shined on the flask a blue light-emitting diode (LED) because it gives off certain wavelengths that are highly efficient at driving the reaction. In the flask she placed an electrode that is activated by particles of light, or photons. "We used a semiconductor electrode that would allow us to substitute light for electricity," said Cole.
  • The Princeton scientists did some additional studies, and made a surprising discovery: They could turn CO2, which contains only one carbon, into a compound with a carbon-carbon bond, which vastly increases the possibilities for creating commercial applications.

Education 2011: A case study in seniority-and burn-out - Buffalo Spree - September 2011... - 74 views

  • The following year teachers are required to “map” curriculums, a long process with no apparent functional use. Teaching for Understanding and Cross Curriculum Literacy are two trendy new programs promoting the latest hot topic. Everyone reads Active Literacy before author Heidi Hayes Jacobs arrives amidst great fanfare to promote her comprehensive program, which administrators cherry-pick, then forget. By 2008 the latest buzz-phrase is Professional Learning Communities. The high school adopts this concept at considerable cost and strife. Three years later Principal Power moves on, and PLCs fizzle. With each new initiative Sara’s enthusiasm diminishes. She has twenty-two years of books, binders, and workshop folders stacked in a file drawer, representing hundreds of hours of abandoned work. Sara digs through the strata like a scientist noting geologic eras. She ponders the energy spent on each new program, technological advance, and philosophical shift, and decides the only way she’ll make it to retirement is to stop caring so much. President Obama introduces the Race to the Top Fund, and by 2010 New York has successfully secured its slice of the cash cow. Common Core Standards are developed in 2011, and a system is put into place to rate teachers based on student test scores. Epilogue In 2013 the anti-union movement hits NY State and teacher unions lose the right to collectively bargain. With the help of key Assembly members, New York Mayor Mike Bloomberg and Governor Andrew Cuomo push through legislation they had endorsed for years eliminating the time-honored practice of laying-off teachers by seniority—“last hired, first fired.” A new math teacher is hired at Sara’s school. Being young and unattached, Bob impresses the new principal, who sees to it that he is not assigned the “problem” kids. Sara remains a competent and dedicated teacher, but the fire is out. She is asked to mentor Bob, but feels no motivation to train the competition. Bob can’t help but notice that Sara shows little interest in the newest reform initiatives. In 2014 a math position is cut due to budget constraints. At half the pay, Bob is clearly the better choice. Sara is laid off, and at age fifty, with a son in college, she joins the unemployed.

Contemplating the consequences of Constructivism - The Learner's Way - 21 views

  • learning is a process which occurs within the mind of the individual as they process stimuli arriving from their sensory buffer from their environment (broadly speaking), into working memory and onward into long-term memory.

      The emphasis does not have to be on the individual, as is common. The social group learns by means of individual, but joined and synchronized, learning.

      Does not sounds like the classroom is empty? Classmates? Who cares about them?
  • It is not always the case that learning is best served when the process begins with direct instruction.
  • Schools provide a rich environment within which such learning may occur
    • Rafael Morales_Gamboa
       
      It is not always the case, and I would rather say that is not often the case, if our cultural legacy that depicts the school in literature and films.
  • best model can be to begin with an independent exploration of new content even when this produces failure
  • schools maximise their impact on the learning that occurs
  • constructivism urges teachers to ensure that the learner is at least as involved in the process as their teachers are
    • Rafael Morales_Gamboa
       
      I would call that "teacher-centred constructivism".
  •  
    Constructivism is one of those ideas we throw around in educational circles without stopping to think about what we mean by it. They are the terms that have multiple meanings, are at once highly technical and common usage and are likely to cause debate and disagreements. Constructivism in particular carries a quantity of baggage with it. It is a term that is appropriated by supporters of educational approaches that are in stark contrast to the opposing view; constructivism vs didactic methods or direct instruction. The question is what are the origins of constructivism and does a belief in this as an approach to understanding learning necessitate an abandonment of direct instruction or is this a false dichotomy?

    "Every year Edge.org poses an Annual Question to dozens of scholars, scientists, writers, artists and thinkers. The respondents this year include the reasonably famous, such as Arianna Huffington, Steven Pinker, Brian Eno, Daniel Dennet, Sam Harris and 13.7's own Stuart Kauffman, as well as the not so famous (like me). "The 2013 question is: "What should we be worried about?" Respondents were urged to raise worries that aren't already on the public radar, or to dispel those that are" (Lombardo, NPR)

When fish come to school, kids get hooked on science - 14 views

  •  
    "A programme that brings live fish into classrooms to teach the fundamentals of biology not only helps students learn, but improves their attitudes about science, a new study finds. The study of nearly 20,000 K-12 students, who raised zebrafish from embryos over the course of a week, found that kids at all grade levels showed significant learning gains. They also responded more positively to statements such as "I know what it's like to be a scientist." The results, to be published by the journal PLOS Biology, suggest that an immersive experience with a living creature can be a particularly successful strategy to engage young people in science, technology, engineering and maths."

Study finds social media has limited effects on teenage life satisfaction - 9 views

  •  
    "Researchers from the Oxford Internet Institute (OII), part of the University of Oxford, used an eight-year survey of UK households (Understanding Society, part of the UK Household Longitudinal Study) to study how long teenagers spent using social media on a normal school day and their corresponding life satisfaction ratings. This is the first large-scale and in-depth study testing not only whether adolescents who report more social media use have lower life satisfaction but also whether the reverse is true. Before this study scientists had little means of disentangling whether adolescents with lower life satisfaction use more social media or whether social media use leads to lower life satisfaction."

The Genius Who Plays For A Living | Popular Science - 35 views
