Immersed In Too Much Information, We Can Sometimes Miss The Big Picture : All Tech Cons... - 22 views

  • Although we find ourselves as travelers in the age of over sharing, it turns out we remain quite adept at avoiding the really tough topics.
  • Google’s Eric Schmidt recently stated that every two days we create as much information as we did from the beginning of civilization through 2003. Perhaps the sheer bulk of data makes it easier to suppress that information which we find overly unpleasant. Who’s got time for a victim in Afghanistan or end-of-life issues with all these Tweets coming in?
  • Between reality TV, 24-hour news, and the constant hammering of the stream, I am less likely to tackle seriously uncomfortable topics. I can bury myself in a mountain of incoming information. And if my stream is any indication, I’m not alone. For me, repression used to be a one man show. Now I am part of a broader movement — mass avoidance through social media.

Shock threat to shut Skype - 0 views

  • eBay says it may have to shut down Skype due to a licensing dispute with the founders of the internet telephony service.
  • eBay has since been licensing the technology from the founders’ new company, Joltid, but the pair recently decided to revoke the licensing agreement.
  • In a quarterly report filed with the US Securities and Exchange Commission, eBay said in no uncertain terms that if it lost the right to use the software it would most likely have to shut Skype down.

  • But, even though Skype has not been a major financial success, it has succeeded in becoming the dominant internet telephony service globally.
  •  
    I use Skype and enjoy the free functionality. It's far from perfect, but has a place in my e-learning toolkit. (I've also used Jah-Jah to call my daughter in Thailand and was very pleased with this alternate take on internet telephony.) Like all things tech, Skype could go. As this article shows, the big hitting billionaires who run the show are in dispute. If i have to switch, so be it! Will Google Voice move into this space? Who knows? Wait and see as the future unrolls on a daily basis

Technology in Schools Faces Questions on Value - NYTimes.com - 9 views

  • Critics counter that, absent clear proof, schools are being motivated by a blind faith in technology and an overemphasis on digital skills — like using PowerPoint and multimedia tools — at the expense of math, reading and writing fundamentals. They say the technology advocates have it backward when they press to upgrade first and ask questions later.
    • Steve Ransom
       
      A valid criticism when technology implementation is decoupled from meaningful and effective pedagogy. You can't buy measurable change/improvement.
  • district was innovating
  • how the district was innovating.
    • Steve Ransom
       
      Again, this is very different than how TEACHERS are innovating their PRACTICES. It's much more challenging than making a slick brochure that communicates how much technology your district has.

  • there is no good way to quantify those achievements — putting them in a tough spot with voters deciding whether to bankroll this approach again
  • “We’ve jumped on bandwagons for different eras without knowing fully what we’re doing. This might just be the new bandwagon,” he said. “I hope not.”
    • Steve Ransom
       
      There's a confidence building statement for you....
  • $46.3 million for laptops, classroom projectors, networking gear and other technology for teachers and administrators.
    • Steve Ransom
       
      Exactly... and how much was spent on equipping teachers to change their practices to effectively leverage this new infrastructure?
  • If we know something works
    • Steve Ransom
       
      And what is that "something"? New technology? If so, you missed the boat.
  • it is hard to separate the effect of the laptops from the effect of the teacher training
  • The high-level analyses that sum up these various studies, not surprisingly, give researchers pause about whether big investments in technology make sense.
    • Steve Ransom
       
      Why does the argument for making schools relevant and using current cultural tools need to be backed with performance data? Give politicians and superintendents horses instead of cars and see how long that lasts.
  • Good teachers, he said, can make good use of computers, while bad teachers won’t, and they and their students could wind up becoming distracted by the technology.
    • Steve Ransom
       
      Finally, a valid point.
  • “Test scores are the same, but look at all the other things students are doing: learning to use the Internet to research, learning to organize their work, learning to use professional writing tools, learning to collaborate with others.”
    • Steve Ransom
       
      Exactly. But somehow, "value" has been equated with test scores alone. Do we have a strong body of research on pencil effectiveness or clay effectiveness or chair effectiveness?
  • “It’s not the stuff that counts — it’s what you do with it that matters.”
  • “There is a connection between the physical hand on the paper and the words on the page,” she said. “It’s intimate.”
  • “They’re inundated with 24/7 media, so they expect it,”
    • Steve Ransom
       
      And you expect them to always engage enthusiastically with tools that are no longer relevant in their culture?
  • The 30 students in the classroom held wireless clickers into which they punched their answers. Seconds later, a pie chart appeared on the screen: 23 percent answered “True,” 70 percent “False,” and 6 percent didn’t know.
    • Steve Ransom
       
      Okay... and you follow up with a totally trivial example of the power of technology in learning.
  • term” that can slide past critical analysis.
  • engagement is a “fluffy
    • Steve Ransom
       
      Very true
  • rofessor Cuban at Stanford argues that keeping children engaged requires an environment of constant novelty, which cannot be sustained.
    • Steve Ransom
       
      If that is so, why not back up your claim by linking to the source here. I have a feeling he has been misquoted and taken out of context here.
  • that computers can distract and not instruct.
    • Steve Ransom
       
      Computers don't really "instruct". That's why we have teachers who are supposed to know what they are doing and why they are doing it... and monitoring kids while keeping learning meaningful.
  • guide on the side.
    • Steve Ransom
       
      But many teachers are simply not prepared for how to do this effectively. To ignore this fact is just naive.
  • Professor Cuban at Stanford
    • Steve Ransom
       
      Are they in love with Cuban or something? Perhaps they should actually look at the research... or interview other authorities. Isn't that what reporting is all about? I think this reporter must be a product of too much Google, right?
  • But she loves the fact that her two children, a fourth-grader and first-grader, are learning technology, including PowerPoint
    • Steve Ransom
       
      Again, the fact that any supporter is happy that their kids are learning PowerPoint illustrates the degree of naiveté in their understanding of technology's role in learning.
  • creating an impetus to rethink education entirely
  • Mr. Share bases his buying decisions on two main factors: what his teachers tell him they need, and his experience. For instance, he said he resisted getting the interactive whiteboards sold as Smart Boards until, one day in 2008, he saw a teacher trying to mimic the product with a jury-rigged projector setup. “It was an ‘Aha!’ moment,” he said, leading him to buy Smart Boards, made by a company called Smart Technologies.
    • Steve Ransom
       
      Herein lies another huge problem. Mr. Director of Technology seems to base no decisions on what the learning and technology literature have to say... nor does he consult those who would be considered authorities on technology infused learning (emphasis on learning here)
  • This is big business.
    • Steve Ransom
       
      No kidding.
  • “Do we really need technology to learn?” she said. “It’s a very valid time to ask the question, right before this goes on the ballot.”
    • Steve Ransom
       
      Anyone who asks that should volunteer to have their home and work computer confiscated. After all, it's just a distraction, right?

Q&A on diaspora - 5 views

  • What do you think are the most important features a social network should have? How would you prioritize them? Do you plan to Build Less or go big? If building less, what is the minimal set of features you can get away with? We plan to “build less.” These are the features which we aim to complete first: 1. A good secure protocol, encrypted at every leg, including a specification for a lightweight, probably HTTPS, RESTful set of routes. We see all of this communication happening between two Diaspora servers, rather than strictly between peers. We realize there is the problem with polling with this model, but we think there are several tricks worth trying which all have their relative pros and cons: PubSub (fast and easy, requires some level of centralization), querying friends servers from the browser side and posting responses back (requires browser side decryption) to name a couple. Alternatively, we are considering going with XMPP altogether due to the ability to be able to push content between nodes, but we need to research it further to see if it is something we would want to implement. 2. A datastore and corresponding interface that can store all of your stuff in one place. MongoDB is what we are looking at for V1, but the redundancy of TahoeFS is intriguing(as well as serving a slightly different purpose). 3. A clear extension framework. Diaspora will be service-agnostic and we will need to make it easy to import from and export to any format/web service. It is also our goal to make Diaspora as content-agnostic as possible, by providing abstract data types and an easily extended UI so that whatever new content people want to store and share can be integrated without re-rewriting parts of the whole application stack. 4. Be your own OpenID provider. Having a single identity across lots of services is great, but why trust a web service to hold it? Once we are the keepers of our own data, we can also selectively allow services access to it through Oauth.

Commentary: Don't prop up failing schools - CNN.com - 0 views

  • Story HighlightsChristensen, Horn: Federal spending on schools is set to jumpThey say it would be a big mistake to use money to let failing schools resist changeCo-authors: Federal money should go to innovators challenging traditional waysThey say technology should be used to create new forms of schooling
  • The most likely result of this stimulus will be to give our schools the luxury of affording not to change.
  • Fourth, direct more funds for research and development to create student-centric learning software. Just a fraction of 1 percent of the $600 billion in K-12 spending from all levels currently goes toward R&D. The federal government should reallocate funds so we can begin to understand not just what learning opportunities work best on average but also what works for whom and under what circumstance. It is vital to fund learning software that captures data about the student and the efficacy of different approaches so we can connect these dots.
