OK, so this is a post that is focused for profs. You all are very familiar with this issue. If you're like me, you also almost at a loss as to what to do. Our students are all hopelessly distracted. I'm in the "ban the laptop" crowd. But, this year the smart phones have started to come out. What to do, what to do...
One thing is for certain, multitasking is not conducive to education. A couple of years ago there were two sides to this argument, but new research is making it more clear that multi-taskers are suckers for irrelevance.
If you're not distracted enough, here's the recent Frontline episode on this issue:
What did you expect when you started these experiments?
Each of the three researchers on this project thought that ... high multitaskers [would be] great at something, although each of us bet on a different thing.
I bet on filtering. I thought, those guys are going to be experts at getting rid of irrelevancy. My second colleague, Eyal Ophir, thought it was going to be the ability to switch from one task to another. And the third of us looked at a third task that we're not running today, which has to do with keeping memory neatly organized. So we each had our own bets, but we all bet high multitaskers were going to be stars at something.
And what did you find out?
We were absolutely shocked. We all lost our bets. It turns out multitaskers are terrible at every aspect of multitasking. They're terrible at ignoring irrelevant information; they're terrible at keeping information in their head nicely and neatly organized; and they're terrible at switching from one task to another.
So what do you make of that?
... We're troubled, because if you think about it, if on the one hand multitasking is growing not only across time, but in younger and younger kids we're observing high levels of multitasking, if that is causing them to be worse at these fundamental abilities -- I mean, think about it: Ignoring irrelevancy -- that seems pretty darn important. Keeping your memory in your head nicely and neatly organized -- that's got to be good. And being able to go from one thing to another? Boy, if you're bad at all of those, life looks pretty difficult.
And in fact, we're starting to see some higher-level effects [of multitasking]. For example, recent work we've done suggests we're worse at analytic reasoning, which of course is extremely valuable for school, for life, etc. So we're very troubled about, on the one hand, the growth, and on the other hand, the essential incompetence or failure. ...
One would think that if people were bad at multitasking, they would stop. However, when we talk with the multitaskers, they seem to think they're great at it and seem totally unfazed and totally able to do more and more and more. We worry about it, because as people become more and more multitaskers, as more and more people -- not just young kids, which we're seeing a great deal of, but even in the workplace, people being forced to multitask, we worry that it may be creating people who are unable to think well and clearly.
... Are there certain kinds of thought that suffer more than others?
It's a great question. The answer is yes. So we know, for example, that people's ability to ignore irrelevancy -- multitaskers love irrelevancy. They get distracted constantly. Multitaskers are very disorganized in keeping their memory going so that we think of them as filing cabinets in the brain where papers are flying everywhere and disorganized, much like my office.
And then we have them being worse at switching from one task to another. ... It's very troubling. And we have not yet found something that they're definitely better at than people who don't multitask.
