      And we've done all of that with education!
  • An organization with cost disease can use lower paid workers, increase the number of consumers per worker, subsidize production, or increase price
  • Cheap graduate students let a college lower the cost of teaching the sections while continuing to produce lectures as an artisanal product, from scratch, on site, real time

  • We ask students to read the best works we can find, whoever produced them and where, but we only ask them to listen to the best lecture a local employee can produce that morning.

      Which is why I think amazing lectures and lecture-notes followed by in person discussion could be powerful. Like a reading group (aka english class) but for video.
  • he very things the US News list of top colleges prizes—low average class size, ratio of staff to students—mean that any institution that tries to create a cost-effective education will move down the list.
  • hese are where most students are, and their experience is what college education is mostly like.
  • a good chunk of the four thousand institutions you haven’t heard of provide an expensive but mediocre education
  • That’s because the fight over MOOCs is really about the story we tell ourselves about higher education: what it is, who it’s for, how it’s delivered, who delivers it.
  • OOCs expand the audience for education to people ill-served or completely shut out from the current system, in the same way phonographs expanded the audience for symphonies to people who couldn’t get to a concert hall, and PCs expanded the users of computing power to people who didn’t work in big companies. Those earlier inventions systems started out markedly inferior to the high-cost alternative: records were scratchy, PCs were crashy. But first they got better, then they got better than that, and finally, they got so good, for so cheap, that they changed people’s sense of what was possible
  • n the US, an undergraduate education used to be an option, one way to get into the middle class. Now it’s a hostage situation, required to avoid falling out of it.
  • Open systems are open. For people used to dealing with institutions that go out of their way to hide their flaws, this makes these systems look terrible at first. But anyone who has watched a piece of open source software improve, or remembers the Britannica people throwing tantrums about Wikipedia, has seen how blistering public criticism makes open systems better.

Reading and the Web - Texts Without Context - NYTimes.com - 49 views

  • It’s also a question, as Mr. Lanier, 49, astutely points out in his new book, “You Are Not a Gadget,” of how online collectivism, social networking and popular software designs are changing the way people think and process information, a question of what becomes of originality and imagination in a world that prizes “metaness” and regards the mash-up as “more important than the sources who were mashed.”

      Core discussion topic? From this, I see a few discussion issues: 1. Do we prize "mash-ups" more than original work? Who is "we" in this? 2. If the answer to #1 is "yes," then the next question is: is this good or bad? 3. Finally, if the answer is "bad" to #2, what place do "mash-ups" have, and how do we help our students see the value in original work?
  • Web 2.0 is creating a “digital forest of mediocrity” and substituting ill-informed speculation for genuine expertise;

      How do teachers help students rise above this "digital forest of mediocrity"?
  • Mr. Johnson added that the book’s migration to the digital realm will turn the solitary act of reading — “a direct exchange between author and reader” — into something far more social and suggested that as online chatter about books grows, “the unity of the book will disperse into a multitude of pages and paragraphs vying for Google’s attention.”
    • Stan Golanka
       
      If Johnson's predictions are true, is this necessarily bad? How much of this concern is "nostalgia"? What would be lost from an academic p.o.v, and what migh be gained?

  • Instead of reading an entire news article, watching an entire television show or listening to an entire speech, growing numbers of people are happy to jump to the summary, the video clip, the sound bite — never mind if context and nuance are lost in the process; never mind if it’s our emotions, more than our sense of reason, that are engaged; never mind if statements haven’t been properly vetted and sourced.
    • Stan Golanka
       
      Should teachers "fight" this, or embrace it? Can summaries/sound bites ever be appropriate for academic discussions?
  • And online research enables scholars to power-search for nuggets of information that might support their theses, saving them the time of wading through stacks of material that might prove marginal but that might have also prompted them to reconsider or refine their original thinking.
  • Digital insiders like Mr. Lanier and Paulina Borsook, the author of the book “Cyberselfish,” have noted the easily distracted, adolescent quality of much of cyberculture. Ms. Borsook describes tech-heads as having “an angry adolescent view of all authority as the Pig Parent,” writing that even older digerati want to think of themselves as “having an Inner Bike Messenger.”
    • Stan Golanka
       
      Can teachers moderate this attitude? Does our (adults) use/non-use of technology help breed this attitude?
  • authors “will increasingly tailor their work to a milieu that the writer Caleb Crain describes as ‘groupiness,’ where people read mainly ‘for the sake of a feeling of belonging’ rather than for personal enlightenment or amusement. As social concerns override literary ones, writers seem fated to eschew virtuosity and experimentation in favor of a bland but immediately accessible style.
    • Stan Golanka
       
      Does this ring true to educators? Are social concerns and literary conerns opposites? How does web publishing affect "literary" publishing, as opposed to "non-literary" publishing?
  • However impossible it is to think of “Jon & Kate Plus Eight” or “Jersey Shore” as art, reality shows have taken over wide swaths of television,
