    Multitasking is a myth

Why Learning and Multitasking Don't Mix | The Creativity Post - 82 views

  • But evidence from psychology, cognitive science, and neuroscience suggests that when students multitask while doing schoolwork, their learning is far spottier and shallower than if the work had their full attention. They understand and remember less, and they have greater difficulty transferring their learning to new contexts.
  • But when students are doing serious work with their minds, they have to have focus.”
  • “Young people have a wildly inflated idea of how many things they can attend to at once, and this demonstration helps drive the point home: If you’re paying attention to your phone, you’re not paying attention to what’s going on in class.”

  • Texting, emailing, and posting on Facebook and other social media sites are by far the most common digital activities students undertake while learning, according to Rosen. That’s a problem, because these operations are actually quite mentally complex, and they draw on the same mental resources—using language, parsing meaning—demanded by schoolwork.
  • “Under most conditions, the brain simply cannot do two complex tasks at the same time. It can happen only when the two tasks are both very simple and when they don’t compete with each other for the same mental resources. An example would be folding laundry and listening to the weather report on the radio. That’s fine. But listening to a lecture while texting, or doing homework and being on Facebook—each of these tasks is very demanding, and each of them uses the same area of the brain, the prefrontal cortex.”
  • “there’s nothing magical about the brains of so-called ‘digital natives’ that keeps them from suffering the inefficiencies of multitasking. They may like to do it, they may even be addicted to it, but there’s no getting around the fact that it’s far better to focus on one task from start to finish.”

SpeEdChange: The Church Task Believers - 6 views

    If you want to have your thinking pushed regarding teaching and technology, Ira Socol's blog here is one to subscribe to. This post is a prime example that challenges many of our assumptions about learning, school, and technology.

WPR Program - At Issue with Ben Merens - 0 views

    A radio program that looks at multi-tasking and its effects. About 2/3 of the way through, it gives an example that came out of Stanford of giving standardized tests to top students and letting them multi-task, vs. average students and not letting them multi-task. The second tier students outperformed the top students!

Multitasking: This Is Your Brain On Media - 6 views

Interviews - Clifford Nass | Digital Nation | FRONTLINE | PBS - 58 views

  • So what we're seeing is less of a notion of a big idea carried through and much more little bursts and snippets. And we see that across media, across film, across, in Web sites, this idea of just do a little bit and then you can run away.
    • Michelle Krill
      I consider this to fit in with my 'plate spinning' analogy.
  • anytime you switch from one task to another, there's something called the "task switch cost," which basically, imagine, is I've got to turn off this part of the brain and turn on this part of the brain. And it's not free; it takes time.
    • Michelle Krill
      I make use of this task switch time by noting things that pass through my brain during this lapse in work time. I keep post-its around all the time and carry a jot it down notebook. It's rationalizing, but I do feel like I make use of the 'lost' time.
  • One of the biggest delusions we hear from students is, "I do five things at once because I don't have time to do them one at a time." And that turns out to be false. That is to say, they would actually be quicker if they did one thing, then the next thing, then the next. It may not be as fun, but they'd be more efficient.

BBC News - Is multi-tasking a myth? - 36 views

  • What that suggests, the researchers say, is that multi-task are more easily distracted by irrelevant information. The more we multi-task, the less we are able to focus properly on just one thing.
  • A raft of studies has found that, actually, multi-tasking is a good way to do several things badly.
  • We're not really multi-tasking. We're switching between tasks in an unfocused or clumsy way."
  • ...2 more annotations...
  • Amazing, but as it turns out, quite logical. "The brain has very specialised modules for different tasks, like language processing and spatial recognition. It stands to reason that two similar tasks are much harder to do simultaneously, because they're using similar bits of tissue."
  • Driving and talking doesn't use the same bits of brain. Answering an e-mail while chatting on the phone does. In effect, we are creating information bottlenecks.
