High Scalability - High Scalability - The Amazing Collective Compute Power of the Ambient Cloud - 4 views

  • Earlier we talked about how a single botnet could harness more compute power than our largest super computers. Well, that's just the start of it. The amount of computer power available to the Ambient Cloud will be truly astounding.
  • By 2014 one estimate is there will be 2 billion PCs. That's a giant reservoir of power to exploit, especially considering these new boxes are stuffed with multiple powerful processors and gigabytes of memory. 7 Billion Smartphones By now it's common wisdom smartphones are the computing platform of the future. It's plausible to assume the total number of mobile phones in use will roughly equal the number of people on earth. That's 7 billion smartphones. Smartphones aren't just tiny little wannabe computers anymore either. They are real computers and are getting more capable all the time.
  • One Google exec estimates that in 12 years an iPod will be able to store all the video ever produced.

  • But all the compute power in the world is of little use if the cores can't talk to each other.
  • Inductive chargers will also make it easier to continually charge devices. Nokia is working on wireless charging. And devices will start harvesting energy from the surroundings. So it looks like the revolution will be fully powered.
  • . Literally billions of dollars are being invested into developing a giant sensor grids to manage power. Other grids will be set up for water, climate, pollution, terrorist attacks, traffic, and virtually everything else you can think to measure and control.
  • . Others predict the smart grid could be 1,000 times larger than the Internet.
  • Clearly this technology has obvious health and medical uses, and it may also figure into consumer and personal entertainment.
  • What if instead smartphones become the cloud?
  • In the future compute capacity will be everywhere. This is one of the amazing gifts of computer technology and also why virtualization has become such a hot datacenter trend.
  • It's out of that collective capacity that an Ambient Cloud can be formed, like a galaxy is formed from interstellar dust. We need to find a more systematic way of putting it to good use.

Why do people dance? | Education | The Guardian - 3 views

  • Lovatt says his own experience proves dance can provide confidence that spills into other areas of life. Suffering from profound reading difficulties at school, he left with no qualifications, and was unable to read until he was 23. "I taught myself to read while working as a dancer in theatres," he says. "I was surrounded by talent and thought it was ridiculous that I couldn't read, so I just sat down and, very slowly, learned."Next, Lovatt studied A-levels, then a degree in psychology and English at Roehampton Institute, ultimately gaining a PhD and taking a senior researcher post at Cambridge University. Now, he combines dancing "nearly every day" with dance research at Hertfordshire University, where he teaches the psychology of performing arts.
  • the best way to attract a compatible mate is to relax and just move naturally to the rhythm
  • "Dance lessons are a bit like plastic surgery," says Lovatt. "They mask the true expression of your genes."
  •  
    Not sure I buy the genetic determinism. But I love the story of Dr Lovatt's educational path and I strongly advocate dance for everybody!

Faceless no more: Facebook admits errors | The Australian - 9 views

  • Staff reacted with shock and disbelief as they learned of the defacement of tribute pages set up to honour 12-year-old Elliott Fletcher and eight-year-old Trinity Bates.
  • Facebook stood accused of being faceless in Australia.
  • "Are people really doing that to a tribute page for a dead child? None of us as a group of people wants to see the product that we built used like that. It's awful."
  • ...4 more annotations...
  • If Facebook is subject to the traditional rules of publishing, then it is legally responsible for all the content that it hosts -- a commercially untenable position for a company of just 1000 employees for 400 million users globally.
  • But in fact, there was no security breach -- the people who defaced the Bates and Fletcher tribute sites had Facebook accounts and the tribute groups or pages were left open for anyone to join or comment.
  • but people who set up tribute sites do not have to wait for the website to remove objectionable material. When a person sets up either a group or fan page on Facebook, they can set controls about who is allowed to join or post content and what types of content -- such as comments, photographs or videos -- are permitted. The person running the tribute page can also delete any content they want without any need for a higher authority to intercede.
  • the problem was compounded by the fact the group founder quit and the page was left without an administrator.
  •  
    "Staff reacted with shock and disbelief as they learned of the defacement of tribute pages set up to honour 12-year-old Elliott Fletcher and eight-year-old Trinity Bates." This is an important article to discuss with students as the defacement of these pages happened because the group was set up for anyone to join and without moderation. Education Education prevents hurt and harm as happened in this case. Of course, it doesn't change the fact that Facebook, even though it is a global company, seems to have a centralized communications structure.

Betrayed - Why Public Education Is Failing: Why administrators don't listen - 21 views

  • In April and May, I asked district administrators for the research and data that support their continued use of reform curricula. Despite several formal requests for public information and a friendly phone call, I’ve received no data and no research. I was told that supporting research was tossed with yesterday’s meatloaf. No, I was actually told it wasn’t kept on hand. (The meatloaf is still there.) I don’t know why the research wouldn’t be kept because administrators keep referring to it (as in “research shows” and “according to the research”). Instead, I was given the names of three organizations and two types of tests, and I was invited to the central office to look over their “great number of materials on the subject of effective instruction in mathematics.” Technically, this is not “data” or “research.” Technically, I think this is called “skating.”

      The author's implication is that the district never had any research despite the claim that it wasn't kept

Some Biologists Find an Urge in Human Nature to Help - NYTimes.com - 3 views

  • This could have happened at some point early in human evolution, when in order to survive, people were forced to cooperate in hunting game or gathering fruit. The path to obligatory cooperation — one that other primates did not take — led to social rules and their enforcement, to human altruism and to language. “Humans putting their heads together in shared cooperative activities are thus the originators of human culture,” Dr. Tomasello writes.

What Makes a Great Teacher? - The Atlantic (January/February 2010) - 10 views

  • What did predict success, interestingly, was a history of perseverance—not just an attitude, but a track record.
  • But another trait seemed to matter even more. Teachers who scored high in “life satisfaction”—reporting that they were very content with their lives—were 43 percent more likely to perform well in the classroom than their less satisfied colleagues.
  • In general, though, Teach for America’s staffers have discovered that past performance—especially the kind you can measure—is the best predictor of future performance. Recruits who have achieved big, measurable goals in college tend to do so as teachers.

  • taxonomy
  • This mapping suggests that each learning object should be based on one learning objective or clear learning goal.
  • The principle of cohesion, however, indicates that there should be a separate learning object for each type of loop. An immediate advantage is that the tutor can select the order in which these learning objects are combined. A tutor dealing with experienced student may wish to deal with these in sequence; another tutor with a different group of students may intersperse these learning objects with object dealing with other features of the language.

      YES! Can we please apply this to items as simple as Word documents and HTML? It would make things so much easier. This also reminds me of good pedagogical design principles BEFORE we had digital learning -- the same should be true for worksheets, handouts, textbooks, etc. It needs to be able to be changed.
  • adaptation
  • The challenge is to maintain this richness in a system composed of reusable components.
  • We must face the challenge of creating learning objects that are cohesive, decoupled and pedagogically rich. This design challenge is associated with the issue of 'repurposability' as we might expect rich learning objects to provide further options for adaptation by local tutors.
    • Adrienne Michetti
       
      Yes, yes, and yes. We need to think beyond our own immediate purposes.

      quite honestly, I would have preferred a non-computer programming example. These principles apply to all technology design, not just programming. Something more accessible would have made this paper stronger.
  • The project involves intervention in syllabus development, the social organisation of learning and the introduction of new eLearning materials. The eLearning resources are being based on the authoring of rich, reusable learning objects. This development provides the focus for the present discussion.
  • The learning objects are being developed both to meet immediate pedagogical needs and to serve this larger goal. This produces extra pressure initially. However, it provides the potential to divide the eventual task among a number of contributing partners, exploiting considerable advantages of scale.
  • A key challenge for the project is to resolve the tensions in a creative and productive way.
    • Adrienne Michetti
       
      Basically, you have to take it all apart and put it back together again. This is fundamental to learning a new way to design anything, really.
  • A compound object consists of two or more independent learning objects that are linked to create the compound.
  • A further important feature is that each simple component object can be reused independently.
  • They thus provide a basis for pedagogical richness that fully exploits the opportunities offered by the technology.

  • the syllabus navigation structure operates at a different layer of organisation for the learning object resources
  • . These syllabi objects operate at a different layer from that of main content objects
  • The key message is the need to establish distinct layers of organisation in eLearning
  • The central challenge is to design for reuse and repurposing.
  •  
    painful reading with the example of Java - but the point remains that all learning objects should be managed and designed with the purpose of being able to use them in the future in ways that are dynamic and reusable. This means de-coupling them and ensuring they are made of distinct pedagogical units.

  • Gestalt theories of visual perception and psychology, specifically those dealing with how the human brain organizes visual information into categories, or groups
  • Closure is the idea that the brain tends to fill in missing information when it perceives an object is missing some of its pieces.
  • Continuance is the idea that once you begin looking in one direction, you will continue to do so until something more significant catches your attention
  • Items of similar size, shape and color tend to be grouped together by the brain, and a semantic relationship between the items is formed.
  • In addition, items in close proximity to or aligned with one another tend to be grouped in a similar way.
  • Contrast addresses the notion of dynamic tensionÔthe degree of conflict that exists within a given design between the visual elements in the composition.
  • The objects in the environment represent the positive space, and the environment itself is the negative space.
  • The rule of thirds is a compositional tool that makes use of the notion that the most interesting compositions are those in which the primary element is off center.
  • The visual center of any page is just slightly above and to the right of the actual (mathematical) center.

  • The principles of design are the guiding truths of our profession, the basic concepts of balance, rhythm, proportion, dominance and unity. Successful use of these core ideas insures a solid foundation upon which any design can thrive.

  • Bottom line is that we will see learners becoming responsible to their peers, audiences, and communities for their learning.  ..and that responsibility will not be based on a measure of their learning (how much or how well), but on what they have learned and what they can do with what they’ve learned.

The Next Movement In Education - Synthesizing Education - 5 views

  • Desks signify the “old guard” of education where people sat in their seats, listened, maintained compliance, and were forced to stare at the front of the room as an older individual barked information. Desks signify a form of education that created widgets and workers for factories where everyone was expected to perform the same rote task at the same time and finish at the same level of understanding.
  • Instead, we should be equipping all classrooms with a diverse mix of tables, couches, exercise balls, bar stool tables, and anything else that reminds us of something other than the traditional classroom. Every classroom should have a variety of these items and as many different combinations as possible. Why? Kids spend 6-7 hours a day in a classroom and every, single one looks the same. Same color, same shape, same seats. If not the same, they look pretty damned similar. It forces kids to think the same in every class and stunts any flow of creative juices that might be triggered by a change in environment. Who’s with me?

Internet as Playground and Factory :: Intro - 6 views

  • Large corporations then profit from this interaction by collecting and selling this data.  Social participation is the oil of the digital economy. Today, communication is a mode of social production facilitated by new capitalist imperatives and it has become increasingly difficult to distinguish between play, consumption and production, life and work, labor and non-labor.  
  • The revenues of today's social aggregators are promising but their speculative value exceeds billions of dollars. Capital manages to expropriate value from the commons; labor goes beyond the factory, all of society is put to work. Every aspect of life drives the digital economy: sexual desire, boredom, friendship — and all becomes fodder for speculative profit.
  • Free Software and similar practices have provided important alternatives to and critiques of traditional modes of intellectual property to date but user agency is not just a question of content ownership. Users should demand data portability, the right to pack up and leave the walled gardens of institutionalized labor à la Facebook or StudiVZ. We should ask which rights users have beyond their roles as consumers and citizens.

Shutting Down the Machine « Ed Tech Journeys - 16 views

  • There is no tiptoeing around this thing. Those who truly desire a transformation of educational system will have to endure many of the same trials and tribulations as those who fought and fight for change in other domains. While educational change agents may not endure the physical pain that so many activists experience; it should come as no surprise that some will be intimidated, or refused tenure, or shunned by colleagues.
  • So, what will it take to transform teaching and learning? What will it take to shut down the pleasant hum of the machine that is so good at turning out 20th century students even though we’re entering the second decade of the 21st century? Leaders with Courage and Commitment!

Algebraic Thinking Through Problem Solving: Exploring Problems That are Not Limited to Single Solution Answers - 9 views

  •  
    For students to make connections in algebraic thinking in problem solving situations, it is important they learn to use algebra symbolism to represent known and unknown information. To this end they must express problem solving situations as linear, quadratic, or exponential models. This way of thinking also requires students to model, represent, analyze, and generalize contextualized problems in a variety of problem solving situations as they begin to think algebraically.
