Atul Gawande: How Do Good Ideas Spread? : The New Yorker - 36 views

  • Why do some innovations spread so swiftly and others so slowly
  • Consider the very different trajectories of surgical anesthesia and antiseptics, both of which were discovered in the nineteenth century.
  • The first public demonstration of anesthesia was in 1846.
  • ...18 more annotations...
  • nsisted that he had found a gas that could render patients insensible to the pain of surgery.
  • The idea spread like a contagion, travelling through letters, meetings, and periodicals. By mid-December, surgeons were administering ether to patients in Paris and London. By February, anesthesia had been used in almost all the capitals of Europe, and by June in most regions of the world.
  • On October 16, 1846, at Massachusetts General Hospital, Morton administered his gas through an inhaler in the mouth of a young man undergoing the excision of a tumor in his jaw.
  • Four weeks later, on November 18th, Bigelow published his report on the discovery of “insensibility produced by inhalation” in the Boston Medical and Surgical Journal.
  • There were forces of resistance, to be sure. Some people criticized anesthesia as a “needless luxury”; clergymen deplored its use to reduce pain during childbirth as a frustration of the Almighty’s designs.
  • Yet soon even the obstructors, “with a run, mounted behind—hurrahing and shouting with the best.” Within seven years, virtually every hospital in America and Britain had adopted the new discovery.
  • Sepsis—infection—was the other great scourge of surgery. It was the single biggest killer of surgical patients, claiming as many as half of those who underwent major operations
  • nfection was so prevalent that suppuration—the discharge of pus from a surgical wound—was thought to be a necessary part of healing.
  • In the eighteen-sixties, the Edinburgh surgeon Joseph Lister read a paper by Louis Pasteur laying out his evidence that spoiling and fermentation were the consequence of microorganisms. Lister became convinced that the same process accounted for wound sepsis.
  • Lister had read about the city of Carlisle’s success in using a small amount of carbolic acid to eliminate the odor of sewage, and reasoned that it was destroying germs. Maybe it could do the same in surgery.
  • During the next few years, he perfected ways to use carbolic acid for cleansing hands and wounds and destroying any germs that might enter the operating field.
  • The result was strikingly lower rates of sepsis and death.
  • Far from it.
  • Surgeons soaked their instruments in carbolic acid, but they continued to operate in black frock coats stiffened with the blood and viscera of previous operations—the badge of a busy practice.
  • hey reused sea sponges without sterilizing them.
  • It was a generation before Lister’s recommendations became routine and the next steps were taken toward the modern standard of asepsis—that is, entirely excluding germs from the surgical field, using heat-sterilized instruments and surgical teams clad in sterile gowns and gloves.
  • Maybe ideas that violate prior beliefs are harder to embrace. To nineteenth-century surgeons, germ theory seemed as illogica
  • The technical complexity might have been part of the difficulty. Giving Lister’s methods “a try” required painstaking attention to detail.

BBC News - How Chinese babies and Mid-East pizza tip US markets - 17 views

  • his year in the US, milk futures leapt 26% and butter prices 62%
  • As a result, there was usually an oversupply of milk products on the market, Levitt says.
  • US and European governments stored excess dairy products
  • ...13 more annotations...
  • nd dairy regulation decreased, driving a new incentive and ability to trade with other nations.
  • s a result, the dairy market tends now toward undersupply.
  • But from December 2013 to February 2014, Chinese demand grew to 20-25% of all global dairy imports, with much of the supply coming from the US and New Zealand.
  • New Zealand is the world's largest dairy exporter, accounting for nearly one-third of the global dairy trade.
  • Many of the nation's cows graze in fields, and a big drought in 2013 caused national milk production to plummet nearly 30%.
  • The US started exporting more dairy, capturing more international market share but pushing up domestic prices.
  • It's not all bad news for New Zealand, though. Traditionally, when the price of dairy goes up, farmers expand operations and produce more milk, thus lowering prices down the line.
  • The increase in supply could eventually lead to cheaper prices in the US, but not for several months.
  • US franchises including KFC, Ihop, Subway, The Cheesecake Factory, Jamba Juice and Papa John's Pizza have all staked claims in the Middle East, with more chains looking to follow.
  • A young, newly urbanised population in the Middle East is demanding more dairy imports.
  • That removed an estimated $6.6bn (£4bn) in annual dairy trade from the global market. In 2013, the EU alone exported $3bn of dairy to Russia, of which cheese accounted for more than one-third.
  • In response, the European Commission has announced it will provide financial support to the dairy industry, subsidising private storage of cheese, skimmed milk powder and butter until they can be sold at a later date.
  • But it will take a little while to see those changes reflected in American supermarkets.

Wired Campus: Skidmore May End Online-Education Program - Chronicle.com - 0 views

  • Although economic downturns tend to push more students to enroll in online education programs, enrollment in University Without Walls remains well shy of where it would need to be for the program to break even
  • The Skidmore Faculty Senate will vote at the end of February on whether to recommend to the Board of Trustees that the program be phased out. The board is expected to make the final decision when it convenes in May.

The Atlantic Online | January/February 2010 | What Makes a Great Teacher? | Amanda Ripley - 82 views

  • embodies the most stunning finding to come out of education research in the past decade: more than any other variable in education—more than schools or curriculum—teachers matter.
  • Parents have always worried about where to send their children to school; but the school, statistically speaking, does not matter as much as which adult stands in front of their children. Teacher quality tends to vary more within schools—even supposedly good schools—than among schools
  • The results are specific and surprising. Things that you might think would help a new teacher achieve success in a poor school—like prior experience working in a low-income neighborhood—don’t seem to matter. Other things that may sound trifling—like a teacher’s extracurricular accomplishments in college—tend to predict greatness.
  • ...3 more annotations...
  • Great teachers, he concluded, constantly reevaluate what they are doing.
  • What did predict success, interestingly, was a history of perseverance—not just an attitude, but a track record
  • Meanwhile, a master’s degree in education seems to have no impact on classroom effectiveness.

What Makes a Great Teacher? - The Atlantic (January/February 2010) - 71 views

  • hey avidly recruited students and their families into the process; they maintained focus, ensuring that everything they did contributed to student learning; they planned exhaustively and purposefully—for the next day or the year ahead—by working backward from the desired outcome; and they worked relentlessly, refusing to surrender to the combined menaces of poverty, bureaucracy, and budgetary shortfalls.
  • one way that great teachers ensure that kids are learning is to frequently check for understanding: Are the kids—all of the kids—following what you are saying? Asking “Does anyone have any questions?” does not work,
  • Students are not always the best judges of their own learning.
  •  
    "For years, the secrets to great teaching have seemed more like alchemy than science, a mix of motivational mumbo jumbo and misty-eyed tales of inspiration and dedication. But for more than a decade, one organization has been tracking hundreds of thousands of kids, and looking at why some teachers can move them three grade levels ahead in a year and others can't. Now, as the Obama administration offers states more than $4 billion to identify and cultivate effective teachers, Teach for America is ready to release its data."

      Yes, how do you remove the stickies from my Edmodo page?
    • Roy Sovis
       
      Cathy, I loaded the Diigo toolbar in IE, Firefox, and Chrome. It's the only toolbar I use. In Firefox and IE, I click on the Diigo icon in the toolbar and mouse hover over "See All Annotations". Another menu will open in whcih you can select the setting you desire in regards to public and private annotations/sticky notes.

      I like using the highlighting and sticky notes. This can be a great tool to use with my students. Just like I am doing for Edmodo by pointing out the different features of the site.

      OK. Nice. Now, how do I get rid of the notes floating on my Edmodo page?
    • A Kashdan
       
      I started using Diigo, but I have no idea why I'm seeing these notes.
    • carmelladoty
       
      Ok, I read the sticky notes, now how do I remove them?
    • Diego Tutor
       
      You can't remove them as they are not your notes, they were published by somebody else in a group where you have access to (Public, Diigo in Education, etc.). You have the option to hide them through the Diigo toolbar, or you can abandon the group not to see any notes from any member in it. :)

  • incremental change, if you’ve looked at any system, has a particular way of breeding immune reactions and resistance to further change. If you bring in a little bit of change people adapt to it and then it gets professionalized.

    Excellent perspective on "The 'W' Word" - use it wisely for what it is - high school and college kids shouldn't be citing any general knowledge encyclopedias for serious research - but that doesn't mean there aren't some excellent uses for it.

The Best Web 2.0 Applications For Education - 2009 | Larry Ferlazzo's Websites of the D... - 116 views

  • The poll for this list — The Best Web 2.0 Applications For Education — 2009 — is located below this post, and closes on February 1, 2010. Please vote for no more than ten of the thirty-two sites listed. Please note that I’ll be listing these sites in my post from my pick from number thirty-two and ending at first place, but the poll is listed in the opposite order.
  • Number twenty: PodOmatic is an extraordinarily easy way to create a podcast. Sign-up and your class has your own channel — all you need is a computer microphone. I’m adding it to The Best Sites To Practice Speaking English.  I’m also adding it to The Best Places Where Students Can Create Online Learning/Teaching Objects For An “Authentic Audience”.
  • PinDax is a new web tool that lets you “pin” virtual “Post It” notes on a virtual bulletin board.  It’s very, very similar to a tool I like a lot called Wallwisher.  It has a lot more “bells and whistles” than Wallwisher.  That additional complexity (and I have to admit, it doesn’t seem that much more complex — it just seems to have a lot more options) doesn’t necessarily make it more attractive for classroom use.
