Dear Parents:Below is an excerpt from the article, You’ll Never Learn! by Annie Murphy Paul which is about digital multi-tasking and how it impairs learning. If your student is texting, surfing the internet, playing video games, on Instagram, Snapchatting, or on any other social media while at the same time doing homework or studying, they need to stop and focus on one task at a time- homework or studying!The last statement in the article sums it up- “Just make sure when they’re doing schoolwork, the cellphones are silent, the video screens are dark, and that every last window is closed but one.”Mrs. Kathryn Doyle Mrs. Chesley Bowling8th Grade Counselor 7th Grade CounselorYou’ll Never Learn!By: Annie Murphy Paul
Students can’t resist multitasking, and it’s impairing their memory.
“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, a psychology professor at California State University–Dominguez Hills. 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.
, a psychology professor at the University of Michigan who’s studied the effects of divided attention on learning, takes a firm line on the brain’s ability to multitask: “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.”
Young people think they can perform two challenging tasks at once, Meyer acknowledges, but “they are deluded,” he declares. It’s difficult for anyone to properly evaluate how well his or her own mental processes are operating, he points out, because most of these processes are unconscious. And, Meyer adds, “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.”
Researchers have documented a cascade of negative outcomes that occurs when students multitask while doing schoolwork. First, the assignment takes longer to complete, because of the time spent on distracting activities and because, upon returning to the assignment, the student has to refamiliarize himself with the material.
Second, the mental fatigue caused by repeatedly dropping and picking up a mental thread leads to more mistakes. The cognitive cost of such task-switching is especially high when students alternate between tasks that call for different sets of expressive “rules”—the formal, precise language required for an English essay, for example, and the casual, friendly tone of an email to a friend.
Third, students’ subsequent memory of what they’re working on will be impaired if their attention is divided. Although we often assume that our memories fail at the moment we can’t recall a fact or concept, the failure may actually have occurred earlier, at the time we originally saved, or encoded, the memory. The moment of encoding is what matters most for retention, and dozens of laboratory studies have demonstrated that , we remember that piece of information less well—or not at all. As the unlucky student spotlighted by Rosen can attest, we can’t remember something that never really entered our consciousness in the first place. And a study last month showed that who see what they’re doing.
Fourth, some research has suggested that when we’re distracted, our brains actually process and store information in different, less useful ways. In in the Proceedings of the National Academy of Sciences, of the University of Texas–Austin and two colleagues asked participants to engage in a learning activity on a computer while also carrying out a second task, counting musical tones that sounded while they worked. Study subjects who did both tasks at once appeared to learn just as well as subjects who did the first task by itself. But upon further probing, the former group proved much less adept at extending and extrapolating their new knowledge to novel contexts—a key capacity that psychologists call transfer.
Brain scans taken during Poldrack’s experiment revealed that different regions of the brain were active under the two conditions, indicating that the brain engages in a different form of memory when forced to pay attention to two streams of information at once. The results suggest, the scientists wrote, that “even if distraction does not decrease the overall level of learning, it can result in the acquisition of knowledge that can be applied less flexibly in new situations.”
Finally, researchers are beginning to demonstrate that media multitasking while learning is negatively associated with students’ grades. In Rosen’s study, students who used Facebook during the 15-minute observation period had lower grade-point averages than those who didn’t go on the site. And two recent studies by , a faculty associate at Harvard’s , found that texting and using Facebook—in class and while doing homework—were negatively correlated with college students’ GPAs. “Engaging in Facebook use or texting while trying to complete schoolwork may tax students’ capacity for cognitive processing and preclude deeper learning,” write Junco and a co-author. (Of course, it’s also plausible that the texting and Facebooking students are those with less willpower or motivation, and thus likely to have lower GPAs even aside from their use of technology.)
Meyer, of the University of Michigan, worries that the problem goes beyond poor grades. “There’s a definite possibility that we are raising a generation that is learning more shallowly than young people in the past,” he says. “The depth of their processing of information is considerably less, because of all the distractions available to them as they learn.”
Given that these distractions aren’t going away, academic and even professional achievement may depend on the ability to ignore digital temptations while learning—a feat akin to the famous marshmallow test. In a series of experiments conducted more than 40 years ago, psychologist tempted young children with a marshmallow, telling them they could have two of the treats if they put off eating one right away. Follow-up studies performed years later found that the kids who were better able to delay gratification not only achieved higher grades and test scores but were also more likely to succeed in school and their careers.
Two years ago, Rosen and his colleagues conducted an information-age version of the marshmallow test. College students who participated in the study were asked to watch a 30-minute videotaped lecture, during which some were sent eight text messages while others were sent four or zero text messages. Those who were interrupted more often scored worse on a test of the lecture’s content; more interestingly, those who responded to the experimenters’ texts right away scored significantly worse than those participants who waited to reply until the lecture was over.
This ability to resist the lure of technology can be consciously cultivated, Rosen maintains. to satisfy their cravings for electronic communication: After they’ve labored on their schoolwork uninterrupted for 15 minutes, they can allow themselves two minutes to text, check websites, and post to their hearts’ content. Then the devices get turned off for another 15 minutes of academics.
Over time, Rosen says, students are able extend their working time to 20, 30, even 45 minutes, as long as they know that an opportunity to get online awaits. “Young people’s technology use is really about quelling anxiety,” he contends. “They don’t want to miss out. They don’t want to be the last person to hear some news, or the ninth person to ‘like’ someone’s post.” Device-checking is a compulsive behavior that must be managed, he says, if young people are to learn and perform at their best.
Rideout, director of the Kaiser study on kids and media use, sees an upside for parents in the new focus on multitasking while learning. “The good thing about this phenomenon is that it’s a relatively discrete behavior that parents actually can do something about,” she says. “It would be hard to enforce a total ban on media multitasking, but parents can draw a line when it comes to homework and studying—telling their kids, ‘This is a time when you will concentrate on just one thing.’ ”
Parents shouldn’t feel like ogres when they do so, she adds. “It’s important to remember that while a lot of kids do media multitask while doing homework, a lot of them don’t. One out of five kids in our study said they ‘never’ engage in other media while doing homework, and another one in five said they do so only ‘a little bit.’ This is not some universal norm that students and parents can’t buck. This is not an unreasonable thing to ask of your kid.”
So here’s the takeaway for parents of Generation M: Stop fretting about how much they’re on Facebook. Don’t harass them about how much they play video games. The digital native boosters are right that this is the social and emotional world in which young people live. Just make sure when they’re doing schoolwork, the cellphones are silent, the video screens are dark, and that every last window is closed but one.”
